Who can tell me some little knowledge

"The solar calendar follows the sun and the lunar calendar follows the moon." This statement is not accurate, whatever the calendar, it cannot be separated from the sun. the patterns of the yellow-red intersection angle between the sun and the earth. The earth is also The seasons change with the change in the angle of intersection between yellow and red; The lunar calendar is the traditional Chinese calendar, also called the lunar calendar, which is closely related to traditional agricultural society. In ancient times, the calendar was calculated accurately using the maximum direct angle of the sun and the phase of the moon, both of which are related to the sun, but the error of the lunar calendar is slightly. larger than that of the solar calendar. For example, the arrival of the twenty-four solar terms is usually measured and calibrated according to the solar calendar. The greatest feature of the lunar calendar is that the marThese are closely linked to the gravitational pull of the moon (related to changes in solar terms), and the moon will be round on the 15th day of the year...

"It rains at midnight in the solar halo, and the wind blows in the lunar halo at noon"

"Rain halo in the middle of the night": The sun is extremely hot during the day, but it still produces a corona, which means that the water vapor is quite humid at night (the temperature is lowest in the middle of the night), rain will inevitably occur;

< p> "Noon moon halo. "The wind" is opposite the solar halo. The temperature is relatively low at night. Although there is a lunar halo, the water vapor may not be enough. Before noon, it will heat up and expand, forming a cool wind.

These proverbs are very useful

On June 29, 2021, GEM announced a planned construction project in Jingmen: recycling technology to produce 100,000 tons/year of high quality batteries. Purity nickel-cobalt salt crystal projects (33,000 tons of battery-grade high-purity nickel sulfate crystals, 33,000 tons of battery-grade high-purity cobalt sulfate crystals and 33,000 tons of battery-grade nickel-cobalt salt crystals cobalt chloride). The total investment is 310 million yuan and the construction period is 9 months. In the normal production year of this project, the turnover reaches 5 billion yuan, the total profit is 250 million yuan, the net profit after tax is about 190 million yuan, and the period dynamic recovery of investments is 4.32 years.

On June 27, 2021, GEM announced that Shenzhen Huifengyuan Investment Co., Ltd. planned to reduce its stake to a maximum of 0.88% of the company's total share capital. As the majority shareholder of GEM, Shenzhen Huifengyuan Investment Co., Ltd. is firmly optimizedste about the bright future of China's environmental protection industry and new energy industry, and is firmly optimistic about the competitiveness, profitability and development prospects of the business " urban mining” from GEM. + “new energy materials” activities.

On June 6, 2021, GEM announced plans to invest 1.8 billion yuan in Taixing Economic Development Zone, Jiangsu Province, using raw materials from developed batteries. scrap as the main material and adopting a circular economy model to form an annual output of 30,000 tons of lithium battery. EIt contains several precursors, 10,000 tons of high-performance cobalt tetraoxide, an annual output of 25,000 tons of high-purity nickel-cobalt-manganese raw materials and 3,000 tons of lithium phosphate raw materials, and a byproduct 50,000 tonnes of anhydrous sodium sulfate. The project is expected to start construction in June 2021. It is expected to complete construction of the 30,000-ton multi-precursor lithium battery project by June 2022 and complete construction of all projects in December 2023. /strong> The company currently has an annual production capacity of 10,000 tons of cobalt tetroxide and 2,000 tons of cobalt flakes per year, which is an important source of profit for the company. After the completion of the project, the annual production value of Taixing Park will reach more than 10 billion, and it will become another park with an output value of 10 billion.rds after the company's 10 billion production value park Jingmen Park, effectively promoting the implementation of the company's 14th park. Five-year plan strategic goal of "exceeding the production value of 30 billion."

On June 6, 2021, GEM announced its intention to sign a cooperation agreement in the China Economic Development Zone. Wuxi airport to build an annual shopping mall. the recycling and processing of 100,000 new energy vehicles and the annual recycling and refurbishment of 100,000 tons of electric batteries.

On April 21, 2021, GEM announced the spin-off of its subsidiary Jiangxi Green Recycling Industry. Co., Ltd. will be listed on GEMGEM is mainly engaged in the electronic waste sector. Through this split, GEM will focus on developing new energy businesses such as manufacturing battery materials.electric. and recycling of used batteries. Green Cycle will leverage the GEM platform of the Shenzhen Stock Exchange to independently raise funds and increase investment in the recovery, dismantling and recycling of unique waste. In 2020, Greencycle made a net profit of 120 million per year. -annual increase of 70%

On April 15, 2021, Greenland published its report for the first quarter of 2021. The company achieved a turnover of 3.8 billion, i.e. increase of 63% over one year. ; net profit attributable to shareholders of listed companies amounted to 276 million, up 150% year-on-yearMainly due to the release of production capacity in the battery materials sector and the strong rising prices of nickel and cobalt. in the first quarter

In its first quarter report, GEM wrote its performance forecastthis operational for June 2021, with a net profit of 475.7 billion, an increase of 120% year-on-year. and 170%The company's core business, ternary precursors and cobalt tetroxide for the whole year, orders are hot, and orders are fully booked throughout the year, effectively promoting the release of production capacities in January and June 2021. profit growth is expected.
