marine fishingThere were many situations involved in ocean fishing. From a business point of view, the monthly salary for coastal fishing was 12000 yuan, and the monthly salary for pelagic fishing was 21000 yuan. Even if the fishing boat on the ocean had a good profit, the salary could reach more than 30,000 yuan, and there were more rewards. However, the risk was also very high. Ocean-going fishing boats were relatively large, usually more than 100 meters long. They had high-tech equipment and many crew members. They could catch several tons or even dozens of tons of sea fish at a time. However, the wind resistance of fishing boats was generally around Level 8, which was much lower than that of merchant ships. They were not stable in the sea and were easily overturned by wind and waves. Therefore, the maritime department forced them to install a weather information receiver.
From the perspective of individual fishermen's work, it was possible to catch all kinds of strange creatures in the ocean, such as salps, which were transparent, rare, and recommended by experts to be released. It was also possible to catch giant lobsters as big as heads. However, if they encountered female lobsters in the spawning season, they had to be released.
In addition, ocean fishing had also become a tourist experience. For example, in Zhejiang, Zhejiang, The fishing harvest of the cruise ship depended on the captain's experience. The seafood caught could be cooked and enjoyed on the ship, and the rest could be divided equally among the tourists.
At the same time, there were also games with the theme of ocean fishing. For example, the ocean fishing game on some online game platforms had 10 levels and could be played in the challenge mode. There were also features such as a sonar system.
Biological patch preparationThe preparation method of the composite biological patch is as follows: a fiber layer, a stripping cloth and a diversion net are laid in a mold from bottom to top in sequence, a sealing bag and the mold form a sealing mold system, the fiber layer, the stripping cloth and the diversion net are arranged in the sealing mold system, and the sealing mold system is connected with a diversion pipe and a vacuum pipe; A vacuum pump is used to evacuate the sealed mold system and maintain a negative pressure state, the matrix layer pulp is automatically injected into the sealed mold system through a diversion pipe, the diversion pipe is closed after the matrix layer pulp fills the entire sealed mold system, and the vacuum pump is turned off; the mold system is demolded after being frozen to obtain the fiber reinforced composite matrix, and the composite biological patch is obtained after being freeze-dried.
There is also a method of preparing a biological patch that involves performing various treatments on the sheet of umbilical cord tissue, including shaking at a specific temperature.(The temperature is 20 - 30 degrees Celsius, and the time is not less than 12 hours). Use a specific hypotonic solution.(For example, the first hypotonic solution is a trimethylol amine water solution with a pH value of 7.0 - 8.5, the second hypotonic solution is a water solution of dodecane sulfuric acid, and the hypertonic solution is a mixed water solution of caprylyl ether and potassium chloride.For example, the first hypotonic solution is a trimethylol amine water solution with a pH value of 7.0 - 8.5, the second hypotonic solution is a water solution of dodecane sulfuric acid, and the hypertonic solution is a mixed water solution of caprylyl ether and potassium chloride.For example, the first hypotonic solution is a water solution of trimethylol amine with a ph value of 7.0 - 8.5, the second hypotonic solution is a water solution of dodecane sulfuric acid, and the hypertonic solution is a mixed water solution of caprylyl ether and potassium chloride...)(including an Isotonic buffer solution and double-distilled water).(at least 3 times, no less than 15 minutes each time), and then freeze drying.(including the subsequent atmospheric pressure pre-freezing, atmospheric pressure freezing of the washed sheet of umbilical cord tissue for no less than 30 minutes at an environmental temperature of no higher than-20 ° C and no lower than-60 ° C, and vacuum drying at a temperature of no lower than-70 ° C for no less than 24 hours), and finally sterilization.(For example, radiation sterilization, the freeze-dried product is sterilized at an environmental temperature of 0 - 10 ° C).
There was another type of biological patch that included a matrix with active groups, and the matrix was modified with a Phosphoryl Choline compound. The preparation method was not mentioned in detail, but the preparation of the biological patch involved the Phosphoryl Choline compound being derived from a compound with a specific structure.

Chinese marine literatureChinese marine literature is an important part of Chinese literature. It was born in the early 20th century and developed from the 1950s to the 1980s. It was a period of development for Chinese literature.
