There are also glass on the Moon! On 7 July, the journalist was informed by the Institute of Physics of the Chinese Academy of Sciences that, through the systematic physical scientific research of Pyongyang samples, my country’s scientific research staff found various types of lunar glass from various sources. More importantly, they also discovered natural glass fibres for the first time in Pyongyang. Relevant research results are published online in the National Scientific Review.

On the lunar surface, there are abundant glass substances generated by volcanic eruptions, geological movements, stone impact, etc. Many of the glass on the moon can be stable for millions of years. The lunar glass is an important element in the exploration of the moon Secretary, not only for the preservation of ancient moon materials, but also for the recording of environmental information in their formation.

Space activities such as rock impact on the moon surface and solar wind radiation exposure.

At this time, researchers analysed the morphology, composition, microstructuring and formation mechanisms of glass substances in Pyongyang samples. They found that there were glass sources on the moon surface of solid, liquid and gas-transformation routes. The mineral melting and rapid cooling of the rocks and traces of the lucrative effects of the lucrative surface of the moon, which are frequently exposed to the surface of the moon, have produced various forms of glass substances, including glass balloons, balloon balloons, throws, glasses of rotary shapes such as balloons, throws, glasses of aerosols, etc.

The glass of the rotary characteristics of the Pyongyang balloon, balloon, titanium, etc.

Of particular concern is the discovery of natural glass fibres by researchers in Pyongyang for the first time. These glass fibres with a superhigh diameter are derived from thermal formations of liquids in the impact process. Liquidity formations of these fibres are higher than glass with low long run diameters, implying a lower counterpart impact temperature and impact rate. This reflects a moderate micro-impact event on the moon surface.

“The natural glass fibres prove that Pyongyang has a good glass-forming capacity and excellent process-formulating character, and confirm the feasibility of using the process of producing glass materials on the surface of the Moon for processing in Pyongyang, which will provide important support for the building of the future moon base.” Shen, Deputy Researcher of the Institute of Physics of the Centre, took the lead.

Lixun precision has made a series of big moves, which has attracted the attention of many institutions, and the leaders of public offering and private placement have conducted personal research. According to the statistics of the securities times, 223 institutions participated in the company’s research activities after Lixun precision announced the construction of the car on February 13; On February 22, after Lixun precision announced a fixed increase of 13.5 billion, 239 institutions conducted research on the company. Excluding institutions with duplicate names, since February, a total of 332 institutions have investigated Lixun precision, ranking first in the number of monthly institutions.

Jufeng view

Medium term strategy:

Jufeng investment adviser believes that the liquidity at the macro level has been gradually improved, and the central bank has continuously cut reserve requirements and interest rates to release liquidity, indicating that the policy bottom has appeared; The medium-term market is expected to rise, but the construction of the market bottom is more complex and there is a time lag between the market bottom and the policy bottom. We should be more patient.

Pre session judgment: the European stock market surged and fell overnight, the US stock market opened high and fell sharply, led by large technology stocks and new energy vehicles, gold and mining stocks rose sharply, and the situation in Ukraine and the expectation of the US Federal Reserve to raise interest rates were the main factors leading to the adjustment of the global market; It is expected that the A shares will open low and the track shares may be sold down. We should pay attention to controlling the position.

In fact, today, the central bank continued its 7-day reverse repurchase operation of 200 billion yuan, and the bid winning interest rate was 2.10%, which was the same as before. The three major A-share indexes collectively opened low, and then rebounded in shock. The gem index fell by 1% in the session, and the science and innovation board 50 took the lead in rising in the red market. Since then, the gem turned red, but after 10:20, the periphery fell again, the A-share rebound fell in resistance, and the gem fell by more than 1%. The international oil price soared by more than 3%, and the gold price stood at US $1920 / ounce.

After the opening, the mining and gas sector led the rise, followed by the rise of photovoltaic and power sectors. The track stocks continued their strength on Wednesday, and the education, insurance, wine and other sectors began to adjust. The market is still a structural market. The concept of Eastern digital computing and Western computing, which rose sharply for four days, rose and fell, driving the decline of many sectors such as Internet, cloud computing and data security.

Yesterday’s afternoon review and closing review suggested: “for the oversold rebound market, we should reduce our expectations. If the rebound is unlimited, we should still pay attention to the risk of decline.” At present, this view remains unchanged. After the rebound of the market is blocked, the bottom will continue to be tamped and the box will be constructed.

Investment suggestions:

Before the Spring Festival, a shares were corrected continuously, and the overvalued track stocks and growth stocks were significantly adjusted. The undervalued blue chips reflected a certain degree of defensive. After the Spring Festival, the market liquidity will be improved, and the spring offensive will be officially launched. In the initial stage, it will still be a structural market, with value and growth one after another. Recently, the oversold rebound of growth stocks and secondary new shares has been launched. In the future, you can choose to sell high, and continue to seek trading opportunities in the low P / E sector.
