On October 22, according to CCTV News, China’s first self-developed 10 MW advanced compressed air energy storage system, after 4,000 hours of test operation, was officially connected to the grid for power generation in Bijie, Guizhou. Significant progress has been made in the field of energy technology.

It is reported that this set of advanced compressed air energy storage system technology and equipment are independently developed by China. It has the characteristics of large scale, low cost, long life, not restricted by geographical conditions, and environmentally friendly. It is an energy storage that can be promoted on a large scale. technology. The system compresses and stores the air when the electricity load is low at night, and then releases the high-pressure air to drive the generator to generate electricity at the peak of the day. A maximum of 40,000 kWh of electricity can be generated per day, which is equivalent to the electricity consumption of 3000 households a day. Played the role of power grid peak shaving.

According to Guo Wenbin, an engineer from the Institute of Engineering Thermophysics of the Chinese Academy of Sciences, the storage medium of this system is air only, and there is no risk of sudden explosion. The air pressure storage range belongs to the medium pressure range, and the risk is controllable.

The system is successfully connected to the grid for power generation, which can not only enhance the power grid's ability to regulate peak and valley power loads, but also store unstable wind power, photovoltaic power generation and other new energy sources, which is equivalent to the grid "stabilizer" and "battery".

On the 7th, the news that the Shenzhou 13 ship-and-arrow combination was transferred to the launch area made many netizens look forward to it.

What mission will the Shenzhou 13 manned spacecraft perform? How are you preparing now?

Three astronauts will start a six-month space life

On the 7th, at the Jiuquan Satellite Launch Center, the Shenzhou 13 manned spacecraft and the Long March 2 F-Yao 13 carrier rocket combination was transferred to the launch area. It is planned to launch in the near future.

Recently, due to the continuous shortage of power supply, many provinces, cities and regions have adopted power curtailment measures, which will affect the production of enterprises. Several key suppliers of Apple and Tesla have announced the suspension of production in China. During the peak season of electronic products such as the new iPhone, the stability of the supply chain will be at risk.

According to the Nikkei Asian Review, Apple and Tesla’s main mechanical parts supplier Yisheng Precision Industry said on Sunday that the company’s factory in Kunshan, Jiangsu suspended production from Sunday to Friday in response to the The city’s policy to stop the supply of industrial electricity. Yisheng pointed out in the announcement that during the shutdown period, it will temporarily maintain operations with inventory, and it is expected to arrange production during holidays or even holidays to meet customer needs.

Apple's printed circuit board supplier Xinxing Electronics said that the company's factories in Suzhou and Kunshan also need to stop production from noon on Sunday to the end of this month, and will mobilize the production capacity of other manufacturing bases to reduce the impact.

It is reported that Apple's acoustic component supplier, Kang Fu Holdings, has a plant in Suzhou, and also announced that it will stop work from 5 to noon on Thursday, and will use inventory to meet customer needs.

The report pointed out that Pegatron, the main iPhone assembler with large production bases in Kunshan and Suzhou, said on Sunday evening that the factory is currently operating as usual, but the generator is ready for further notice from the city government. In addition, the manufacturing plants of Foxconn, another Apple assembler, in Longhua, Guanlan, Taiyuan and Zhengzhou have not been affected by power supply restrictions.

According to informed sources, several major chip packaging and testing service providers such as Intel, Nvidia, and Qualcomm have also received notices requesting factory shutdowns in Jiangsu Province for a few days, and chip supply in the electronics industry will be further affected.

NXP, Infineon and ASE's semiconductor packaging materials supplier Changhua Technology also announced that the factory will be suspended from the evening of September 26 to the end of the month.

News on September 17 According to a CCTV news report, at about 13:30 on September 17, the Shenzhou 12 manned spacecraft’s return cabin reverse thrust engine successfully ignited and landed safely in the scheduled area of the Dongfeng landing site. This is the first time the Shenzhou spacecraft has landed at the Dongfeng landing site.

The door of the Shenzhou 12 return cabin was opened, and the three astronauts were in good condition.

According to CCTV news, in the Shenzhou 1 to Shenzhou 11 missions, the Dongfeng Landing Site was used as a backup landing site for manned missions. It has been constructed simultaneously with the Siziwangqi Landing Site. With the continuous development of my country’s manned space project, Dongfeng Landing The advantages of field normalization and emergency standby continue to appear.

On June 17, 2021, the Shenzhou 12 manned spacecraft was launched from the Jiuquan Satellite Launch Center. Three astronauts Nie Haisheng, Liu Boming, and Tang Hongbo led the expedition and started a three-month flight mission. The three became the first space visitors after China's manned spaceflight entered the space station stage.

The Shenzhou 12 manned flight mission is the seventh manned space flight organized and implemented by my country, and it is also the first manned space flight during the key technology verification and construction phase of the Chinese space station. During the operation in orbit, the astronauts completed the long-term stay test in the space station assembly, which tested the space station assembly's ability to guarantee the life, work, and health of the astronauts, related technologies, and the ability of the astronauts to perform flight missions. At the same time, the astronauts organized and implemented two out-of-vehicle activities, and with the support of the robotic arm, they carried out operations such as the assembly of related equipment outside the space station.

The crew of the Shenzhou 12 astronauts worked and lived in the space station complex for 90 days, setting a record for the duration of a single mission by Chinese astronauts. Before returning, the Shenzhou 12 manned spacecraft and the space station combination completed the circumnavigation and radial rendezvous tests, which successfully verified the radial rendezvous technology and laid an important technical foundation for subsequent manned missions.

According to CCTV, my country’s second-generation new crown vaccine has completed phase II clinical trials.

Recently, news about the development of the second-generation new crown vaccine and specific drugs for the treatment of new crown pneumonia has received widespread attention. What role will the second-generation vaccines and specific drugs play in preventing the new crown pneumonia epidemic? When will it be listed?

Head of the Vaccine R&D Team of the Scientific Research Group and Director of the Science and Technology Development Center of the National Health Commission, said: “First, my country’s vaccine R&D units have carried out research on inactivated vaccines against Gamma and Delta strains. Research on broad-spectrum or multivalent recombinant protein vaccines of different mutant strains, the third is to develop adenovirus vector vaccines and nucleic acid vaccines against Beta strains and Delta strains."

Zhu Jingjin, Secretary of the Party Committee of Sinopharm Group China: "At present, we have prepared vaccines against variant strains such as Delta and Beta. Broad-spectrum recombinant protein second-generation vaccines have also been developed, and phase I and II clinical trials have been completed.
