As we all know, as a bridge between users and the digital world, the smartphone operating system is self-evident. If it is not stable enough, it will affect the user experience.

As the world’s leading communication technology company, Huawei has demonstrated strong innovation strength in the field of smart phone operating system, and its HarmonyOS OS system has attracted much attention.

Because unlike other mobile phone manufacturers who customize the Android system, Huawei HarmonyOS is an independent operating system, and it will be completely separated from Android in the future.

Therefore, every upgrade of HarmonyOS OS system will make many users expect value, especially recently, the official version of HarmonyOS OS 4.2 has struck again.

It is reported that Huawei’s Mate50 series, Mate X3 series, P60 series and other nine models are fully open to upgrade the official version of HarmonyOS 4.2 in HarmonyOS, which is undoubtedly a great benefit for Huawei users.

According to the upgrade plan previously announced by Huawei officials, nine models including Huawei Mate50 series, Mate X3 series and P60 series will complete the upgrade of HarmonyOS OS 4.2 in April-June.

Then the unlimited opening of the official version of the upgrade is even more exciting for users who hold these models, at least in terms of update speed, which has accelerated a lot.

It is worth mentioning that these models have previously pushed the Beta version update of HarmonyOS4.2.0.120 in HarmonyOS, with the version number of 4.2.0.120.

It can be said that in terms of the pace of upgrade, the speed of HarmonyOS OS 4.2 is still very fast. Even if you don’t upgrade to everyone’s models this time, the number of models covered by HarmonyOS OS 4.2 version is still very large.

In this case, it is estimated that it won’t be long before the test recruitment will be conducted again, so as to upgrade more models to the new version.

In particular, the pollen of Huawei Mate40 series should be tested and recruited next, so you don’t have to worry about not upgrading.

After all, Huawei Mate30 series, Huawei Nova6 series, Huawei P40 series, Enjoy 50 Pro, Glory 30 and other models are all on the way.

As a very popular model in that year, Huawei Mate40 series has no reason not to update quickly, and the parameters of the product itself are not weak now.

Take Huawei Mate40 Pro as an example, it is equipped with HiSilicon Kirin 9000 high-end dual-mode 5G flagship chip and 5nm process. The CPU frequency is 1 * A77 3.13 GHz+3 * A77 2.54 GHz+4 * A55 2.05 GHz.

At the same time, it also has built-in 24-core ARM Mali-G78 GPU chip and integrated Ba Long 5000 5G baseband chip, covering 11 5G frequency bands, and there is no problem in performance.

Coupled with high refresh rate screen, customized Sony IMX700 sensor, 66W super fast charging, 50W wireless fast charging, wireless reverse charging function, NFC, infrared remote control, stereo double-lift, etc., the comprehensive level is very strong.

That is to say, after upgrading to HarmonyOS OS 4.2, Huawei Mate40 series models will definitely change a lot, just need patience.

There are quite a few models pushed this time, and a lot of pollen has been upgraded. Most of the feedback said that the fluency is very strong.

There are also pollen claims that advertising has decreased, especially the interception function of "shake" advertising jump in the application, which is really very easy to use and very critical.

And some pollen said that after the update to the new version, some changes have taken place in the theme. It can be said that the overall change is indeed greater than the HarmonyOS OS 4.0 version.

However, there are also some pollen that there is some pressure on battery life, and even feel that after updating to the new version, the battery loss is much faster than before.

Moreover, some pollen said that it has been updated to a new version, but many functions are still exclusive to the new machine, such as AI retouching, and there is no way to experience it in the old model.

And some users said that after updating to the new version, they didn’t feel particularly improved, but they felt like they had brushed a version number.

It seems that different models will indeed bring different experiences, and users who have not yet updated need to be psychologically prepared.

Finally, for users with Huawei Mate50 series, Mate X3 series and P60 series, upgrading the official version of HarmonyOS OS 4.2 will be a very worthwhile experience.

Then the question is coming, will everyone upgrade? Welcome to reply to the discussion.

shield machineAlso called full-face tunnel boring machine.

This is a sharp weapon for "entering the ground"

However, in China, there are shield machines that can "climb steep slopes"

Let the huge and heavy "steel pangolin" climb upwards.

It’s not an easy task.

How does it climb up without slipping?

How to deal with the excavated slag?

Approaching togetherThe first one in China will "climb the steep slope"

Full-face hard rock tunnel boring machine-"Yongning"

China Railway Industry "Yongning" is the first full-face hard rock tunnel boring machine in China, also known as "steel pangolin".It has a diameter of 7.23 meters, a total length of 122 meters and a weight of 1550 tons.

When a common roadheader digs a tunnel, it can only "go straight" in the horizontal direction. For a roadheader with a weight of 1,000 tons and more than 10,000 parts, every time the slope rises, it is a great test from construction safety to parts design.

"Yongning" excavatedNo.1 diversion inclined shaft,The total length is 927 meters, and the vertical drop is over 550 meters.It is an important step in the construction of pumped storage power station.

The diameter is over 7 meters and the slope is over 36 degrees. There is no successful precedent at home and abroad to dig such a large tunnel in the mountain by mechanized equipment.Next, Yongning has to complete three major challenges ↓

1 How does Yongning climb up?

The climbing mode of Yongning relies on the structure of Parthenocissus tricuspidata. The research team added two four groups of eight "legs" before and after, and there were 16 "feet".

?

In order to make the shield machine "climb to the top of the mountain" safely, more than 50 experts held nearly 40 coordination meetings. After 40 months of research, design and test, in August 2022, the first domestic shield machine that could "climb the steep slope" was successfully rolled off the assembly line.

2. Why didn’t Yongning "slide"?

When the 1000-ton Yongning is heading up the mountain, the most important thing is to ensure construction safety and prevent falling.

There is a huge support on the wall of the cave, which is the double anti-slip system of shield machine. This anti-skid system was applied to "Yongning" after a month of limit test.

To this end, the research team also made an experiment in the field. In order to simulate the operation of Yongning under extreme conditions, a foundation pit with a diameter of 7 meters and a depth of 20 meters was excavated, and the renovation cost millions of yuan.

?

Even if the iron plates on both sides are smooth, the anti-skid system of Yongning can still hold still, which is equivalent to a much higher safety factor.

It can be seen from the red mark on the cave wall that the anti-skid system is reliable after many tests.

3. How did Yongning ship carry out the slag?

When the "Yongning" is driving, the generated slag will roll down the slope at an accelerated speed. If it is not careful, it will cause the gravel to splash, which is extremely risky.To this end, engineers specially designed a slag chute, which was then transported out of the tunnel by truck.

The research team specially installed a sprinkler system to spray water through this sprinkler head. In the process, gravel and dust will be washed in the chute and flow to the bottom of the tunnel.

?

At 16: 18 on December 14th, Yongning opened the No.1 diversion inclined shaft.Yongning successfully completed the excavation task of No.1 inclined shaft, filling the technical gap in the field of inclined shaft construction in China.

Soon, "Yongning" and more than 2,000 builders will embark on a new journey and excavate the No.2 diversion inclined shaft.

Seven out of every 10 shield machines in the world come from China.Today, engineers in China have innovated the shield machine, which can only move horizontally, to be able to go up, down and turn. Praise!

In May this year, Bao Junyue, known as the domestic "pure electric Jimny", was officially listed. The new car is positioned as a small pure electric SUV, and the prices of the two models are 79,800 yuan and 89,800 yuan respectively.

I have to say that SAIC-GM-Wuling knows the psychology of domestic consumers very well. Since Suzuki withdrew from the domestic market, its small off-road vehicle Jimny is hard to find a car in the domestic market. Buying Jimny through parallel imported car channels, the price increase is basically the same as the car price.

In other words, this Suzuki Jimny with a price of 150,000 yuan will cost you 300,000 yuan if you want to buy it in the domestic market. Even if the market drops later, the price of moving a car will not be lower than 260 thousand.

It is at this stall that SAIC-GM-Wuling timely launched Baojun Yueye, a small pure electric vehicle. Although in off-road performance, Baojun off-road is obviously very different from Suzuki Jimny, but the square design also makes it have a different general temperament, plus the layout of three doors and four seats, so many people will call Baojun Yue "electric Jimny".

For those young consumers who have no off-road demand and just want to buy a personalized car, spending 70,000 to 80,000 yuan to buy a personalized Baojunyue can also satisfy the curiosity to some extent.

Although at present, Baojun Yue’s market performance is not as good as expected, but the monthly sales of two or three thousand vehicles can make sense for Baojun, a car brand on the verge of bankruptcy.

Moreover, in this class, Bao Junyue has no rivals.

However, on August 28th, the official map of the brand-new model Panda Knight of Geely Automobile was officially released, so that Bao Junyue is about to usher in a brand-new opponent.

From the picture, Panda Knight also adopted the design style of hard-core off-road vehicle in appearance design. Angular body lines and a large area of blackened bumper under the front of the car make the new car look wild. The rounded headlights on both sides of the front net also add some retro and lovely elements to the new car. If you don’t look at the Geely English logo on Qianzhong.com, you may mistakenly think that it is a scaled-down version of "Pure Electric Tank 300".

On the side of the car body, Geely Knight is not only equipped with blackened wheel eyebrows, but also designed a ladder similar to Land Rover Defender at the rear of the car. Although it’s just decoration, it’s held in the car. Above the roof, the luggage rack necessary for off-road vehicles is not absent from the Panda Knight.

The rear of the car is equipped with a "C"-shaped taillight and a wide rear bumper, with a length, width and height of 3135/1565/1655mm and a wheelbase of 2015mm respectively.

In the interior design, Panda Knight is also equipped with an 8-inch central control panel and a 9.2-inch color instrument panel, and the steering wheel is designed with a double-spoke flat bottom. Panda is actually equipped with Bluetooth keys, mobile APP remote control, car Bluetooth and low-speed crawling.

The new car will be equipped with permanent magnet synchronous motor and lithium iron phosphate battery. The maximum power is 30 kW, the maximum torque is 110 Nm, and the pure electric cruising range is over 200 km. It supports a fast charge of up to 22 kW, and it only takes 30 minutes to charge the power from 30% to 80%.

The new car will be officially launched in September, and it is expected that the price should be lower than Bao Junyue.

Beijing News Shell Financial News(Reporter Bai Haotian) On September 10, it was officially listed, with a total of three models, with a limited-time preferential price of 199,900 yuan-289,900 yuan.

The design of Extreme Yue 07 incorporates elements such as frameless doors, hatchback tailgates and doorknobs. The length, width and height of the new car are 4953/1989/1480 mm and the wheelbase is 3013 mm.

The vehicle applies the large model to the intelligent cockpit and intelligent driving. The intelligent cockpit uses a 35.6-inch through screen, based on Qualcomm Snapdragon 8295P chip, which supports a variety of software experiences. The AI ? ? big model can continue to learn in voice interaction.

In terms of intelligent driving, Extreme Yue 07 cooperated with Baidu to launch ASD(Apollo Self Driving) advanced intelligent driving system, which was built based on ADFM, Baidu Apollo’s L4 automatic driving model, and realized the intelligent driving scheme of pure vision and end-to-end large model.

In terms of power, the Extreme Yue 07 is based on the vast architecture. The performance version is equipped with front and rear double motors, with a maximum power of 530 kW, and the cruising range of long-life models can reach 880 kilometers.

If the engine is the heart of the car, then the gearbox is an adjustment mechanism for the function of the heart, and the quality of the gearbox can bring better feelings to the driver. For example, the slow start, smooth speed increase or timely supply of power response are all determined by the gearbox.

Although Japanese gearboxes such as Aisin and ZF are very good, China’s domestic gearboxes are not bad, and one of them is one of the top ten in the world.

Let’s talk about this seven-speed dual-clutch gearbox of the Great Wall, which has been on the Great Wall for many years, and its durability and driving experience are also quite good. With the 1.5T engine and front and rear suspension system of the Great Wall, whether it is the off-road ability of the big dog or the strong power of Harvard h6, it is the fresh power provided by this seven-speed wet dual-clutch gearbox.

The second Geely DSI 6AT gearbox.

Geely has rushed to the position of the domestic leader in recent years. Not only with clever sales strategy and marketing methods, this domestic top three gearbox has accounted for quite enough credit.to sayeconomicalSome of the models, the gearbox carried by Geely Emgrand, make the power play a full and good economic ability. Whether it is home or online car, its economic performance is completely without black influence.

The third model, Chery Wan Liyang cvt25 gearbox, is said to be a technical stream. Chery’s engine and gearbox are among the most capable domestic cars. The series of Chery models of this gearbox jointly developed by Chery and Wan Liyang are equipped with this gearbox. In addition to the CVT’s own high speed, stable and simple structure and low maintenance cost, the improved gearbox of this car has the advantages of high efficiency, low fuel consumption and low noise. Among them, it is more inclined to household use, which is not inferior to Honda’s cvt stepless gearbox.

The last one is DF515 of Changan, a dual-clutch gearbox. Apart from the famous Blue Whale engine in Changan, there are only five five-speed dual-clutch gearboxes of DF515.gearHowever, the speed increase is smooth, and it can really meet the use of daily travel. It is released on cs series models respectively, which meets the needs of mass consumers at limited cost, which Changan has done very well.

　　Beijing, Nov. 13 (Xinhua) According to CNN, on the evening of the 12th local time, the US Democratic Party won 50 seats in the mid-term election, locking in the control of the Senate. In celebrating the victory of the Democratic Party, Biden said that he was "satisfied" with the result and "very much looking forward to the next few years."

　　"We feel good about the situation now, and I know that I am an optimist. I knew this from the beginning," Biden said that night. "So I am not surprised by the voting result, but very satisfied."

　　Biden said that he believes that the current vote rate reflects the "quality of candidates" of the Democratic Party, and they have been "working in the same direction".

　　In addition, Biden also said, "I feel very good and I am looking forward to the next few years."

　　According to previous reports, Catherine Cortes Maasto, the incumbent senator of the Democratic Party, defeated her Republican rival Adam Laxalt with 48.7% of the votes and won the Senate election in Nevada. The Democratic Party won 50 seats in the Senate and continued its control over the Senate.

　　At present, the candidates for the Senate seat in Georgia have not yet come to a conclusion, and a runoff election will be held on December 6. If the Democratic Party finally wins the seats, it will first reach 51 seats and win the control of the Senate. If the Republican Party finally wins the Senate seat election in Georgia, the two sides will each occupy 50 seats in the Senate. At that time, Vice President Harris can break the deadlock in the case of a tie vote, and the Democratic Party can still control the Senate.
