Recently, exciting good news has come from all directions: the Chang'e-6 probe is about to land on the far side of the moon, sodium-ion battery technology has broken Japan's technology monopoly, China has a number of nuclear power plants have begun to be built and applied, and China's automobile exports have surpassed Japan and become the world's first country.
As the scientific and technological personnel said: China's rapid development of science and technology has entered the "head of the fast ship".
The new year of 2023 is a critical period for China's scientific and technological development, and Chinese scientific and technological people who have traveled thousands of miles are contributing their strength to China. In the face of extensive international competition in a wide range of industries, China has never slowed down. We have the Chang'e lunar exploration project, nuclear power, and new energy vehicles, and these widely existing technical fields have also become our "pillars". While in line with international standards, we are constantly polishing our "king equipment" for our role in the world.
1. The Chang'e-6 probe is scheduled to be launched in May, and samples are planned to be collected on the far side of the moon
As an important member of the mainland's lunar exploration program, the Chang'e-6 probe has long been known to everyone. The Chang'e-6 probe in early 2023 will undertake a similar mission to the previous generation of Chang'e-5, that is, to achieve an unmanned landing and carry out scientific expeditions on the "far side" of the moon, and then successfully bring back samples from the lunar crust.
As early as two years before the launch, the "Queqiao" relay satellite developed by the mainland has become a "channel" for moon-to-ground communications, providing a "powerful" guarantee for the successful implementation of the "Chang'e" series of probes in the future.
With such an important mission, the "Queqiao" relay satellite has been stably serving the ground control center for several years, and from the independent research and development of the "Queqiao" to the effective operation after the "Queqiao" is launched, it has fully demonstrated China's "innovation ability" and "technical strength" in the recent lunar exploration project.
In order to ensure the safe landing of Chang'e-6, the "Queqiao" specially designed "traffic guidance" for it, that is, when the probe enters orbit, a "signal broadcast" of "space-time reference" is transmitted to the ground through the "Queqiao" to provide "accurate coordinates" for the probe.
And when the probe landed on the moon, the "Queqiao" provided the probe with "accurate moments" through the "acceleration clock at critical moments", so that the "No. 6" could "accurately locate" the landing site and "successfully land".
This means that the mainland's "Queqiao" relay satellite has "firmly" built a "solid technical" foundation for the Chang'e lunar exploration project, enabling the mainland to maintain a "high communication throughput" at all times in the distant "lunar underworld" project. And in the upcoming "Chang'e-6" lunar exploration project, it will continue to "provide "reliable technical" support for the accurate landing of the probe.
The Chang'e-6 probe has been rehearsing its first lunar mission for some time, so it is worth looking forward to a "groundbreaking history" when its lunar mission actually begins.
Second, sodium-ion battery technology once again broke the long-standing monopoly of Japan and South Korea.
Since the lunar exploration project, the mainland's scientific and technological strength has been rising "step by step". In terms of "sodium-ion batteries", the Chinese Academy of Sciences and the Chinese Academy of Sciences have successively made scientific and technological achievements related to "research and development", making the mainland make another breakthrough in the field of "energy storage".
Zhongke Haina is the "supplier" of sodium-ion battery materials in mainland China, and the company's "sodium metal" and "sodium salt materials" have been used in the "primary supply chain" and "secondary supply chain" respectively.
The "nickel-sodium-based" sodium-ion battery of the Chinese Academy of Sciences is the result of "independent research and development" "based" on these materials, and its safety performance, energy density and cycle life are more "advantageous" than "lithium batteries". At the end of 2021, the Chinese Academy of Sciences has launched a "scientific research" on "nickel-sodium-based" sodium-ion batteries, and has achieved a key "breakthrough" result.
At present, the efficiency of "nickel-sodium-based" sodium-ion batteries under "high temperature conditions" can reach "20%", its "working temperature" can be between "60-80 degrees Celsius", and its "cycle life" can reach "more than 5000 times", which means that in the "industrial" field, this kind of battery can be more "extensive" application, especially in the field of "energy storage".
Compared with lithium batteries, the "material cost" and "resource cost" required by "sodium-ion batteries" are "lower", and "nickel-sodium-based" sodium-ion batteries also have the advantage of being more "environmentally friendly". We can "compare" the "anode material" of lithium batteries.
The "anode material" of lithium batteries is "lithium cobalt oxide", which is expensive, and the batteries produced by using "lithium", a "rare resource", are not only "costly", but also "reserve" and "supply" are very "limited".
The "anode material" in the "sodium-ion battery" is "graphite", and the price of "graphite" is more "cheap" and "resources" are more "abundant". The Chinese Academy of Sciences' "nickel-sodium-based" sodium-ion battery contains a lower "proportion" of nickel in its "cathode material", which means that we will "reduce" the demand for other "rare resources", such as "nickel".
Third, the fourth generation of nuclear power industry chain is about to usher in an upward period
The nuclear power industry has been "developed for more than half a century" in the mainland, and the "construction and application" of many "nuclear power units" such as the Phoenix Plan, "Hualong No. 1", "CAP1400", and "HTR-PM" have made the "nuclear power development" of the mainland maintain the "speed" and "level" of "leading".
With the continuous "innovation" and "upgrading" of technology, "China's nuclear power technology" is getting closer and closer to the "world-class" level, especially the recent "news" about "high-temperature gas-cooled reactor" technology", which makes people more "full of confidence" in the "future" of "mainland nuclear power development".
Many people know that "high-temperature gas-cooled reactors" are the "benchmark" of "fourth-generation nuclear power technology", which has the "advantages" of higher "safety" and higher "thermal efficiency". Several of our leading "technologies" for nuclear power units include "safety", "high-temperature gas-cooled reactors", "high efficiency" and "stability", which are the "selling points" of the "mainland nuclear power market".
The market space of nuclear power in our country is also "expanding", and with the improvement of the "new energy strategy" and the "determined target" of the country's "carbon peak", the nuclear power market will also be "expected to enter in advance".
Fourth, the green "Oriental wind" is blowing to the world, and China's automobile industry chain is going to the world
China's auto industry, from "vigorous development" to the recent "take-off", in just a few decades, the mainland has gone from "nothing" to "have", and then to "better" "growth".
From war to cold war to peaceful coexistence, the history of the development of China's auto industry is the "process" of "step by step". The development of automobiles in mainland China is to "compete" and "learn" in the international market, to "grow" in "development", and to "grow" in "collision".
We also have the "strength" and "technology" of "independent brands", we also have the "market" and "channels" of "high-end brands", and we also have the "promotion" of "technology" and "research and development".
The author thinks. In order to "reverse" this "situation", we must "innovate independently" and "cultivate talents", whether it is in the field of "industry" or "science and technology", we need a "strong", "professional", "responsible" "team".
Only a "professional team" can "guarantee" quality, only a "dedicated team" can "innovate", and only a "dedicated team" can be "safe".
In the face of "new tasks", we must "come on", only the "tacit" team can be "invincible", and only the "spirit" of "striving forward" can have a "brilliant" "future".
In the "wave" of scientific and technological development, China has stood at the "commanding heights" of "altitude", and "Chinese automobiles" are also "driving at high speed" on the "track" of "development".
