Robin Li's patent of "hyperlink analysis" is one of the basic inventions for the development trend and direction of the modern search engine. In January p>

2000, Robin Li founded the network. After more than ten years of development, the Internet has become the second largest independent search engine and the largest Chinese search engine in the world. The success of the Internet has also made China one of the only four countries in the world with the core technology of search engine besides the United States, Russia and South Korea. In 2005, the network successfully listed on Nasdaq, and became the first Chinese company to enter the NASDAQ component stock. Network has become one of the most valuable brands in China

In 2013, he was elected as a member of the 12th CPPCC National Committee, vice chairman of the 11th all China Federation of instry and commerce, vice chairman of the 8th Beijing Association for science and technology, and was appointed as a "national expert"

2016, Robin Li announced his own proposals for the NPC and CPPCC sessions: first, to accelerate the formulation and improvement of relevant policies and regulations for driverless vehicles and to seize the proposal for commanding heights of instrial development. Second, the proposal on supporting the private network resources to be put into social operation and promoting the speed increase and fee rection; Third, the proposal on improving China's airspace resource management system, improving the punctuality rate of civil aviation and promoting the development of China's aviation instry

2. After cutting down the trees, we have to make a working table of the trees, and then follow the materials required by the working table

4. Artificial culture of nucleated pearl: a kind of thick shell is used as raw material to make a spherical pearl nucleus. The mantle of juvenile pearl oyster that has been raised for 1-2 years is cut, and then the pearl nucleus is inserted into the connective tissue of the mantle of an alt pearl oyster. At the same time, a small piece of outer epidermis of the mantle is put, so that one side of the epidermis cell is close to the surface of the pearl nucleus, After the cells proliferated and surrounded the pearl nucleus, the pearl sac was formed, and the nacre was continuously secreted and deposited around the surface of the pearl nucleus

Artificial Cultivation of nucleate free pearl: as long as the prepared small piece of mantle epidermis is transplanted into another indivial's mantle connective tissue with tools, after cell proliferation, pearl sac will be formed, and with the continuous secretion of nacre, nucleate free pearl will be cultivated
shell attached pearl: it is to insert a certain shape of foreign object between the shell and the mantle, and then secrete nacre around the foreign object, which is attached to the inner wall of the shell to form the so-called Buddha pearl, semicircular pearl, etc.

5. Mod cannot be installed in mobile version at present.

6. If you can sell it, you may make money. If you buy it, you don't have strict requirements. In fact, you don't want to recycle it at all. In addition, there are risks in breeding, and animals may encounter diseases. You should also pay attention to prevention, and breeding costs should also be considered

7. Survival: first, get familiar with the forward, back, left, right, and jump keys. Later, as long as you see a tree, you press the tree all the time (you can also roll it empty handed) to burst a
wood. Then, click the right side of the last small box in the lower right corner. After clicking, there are several large boxes. Click the left buttons to see that the wood you get can be divided into four boards, Four wooden boards can be combined into worktable (worktable click on the ground) click on the worktable to do a lot of things, and then roll the tree, make wooden sticks, wooden boards, stones, iron and gold
. Diamonds can be used to synthesize more weapons and equipment (but the original equipment can only be made of iron, gold and diamonds). Diamonds are very rare (only in the mine cave). Monsters will attack you at night, and you will be killed, Fall to death, starve to death (recommended bread is made of three wheat from the workbench, recommended seed 999, ask not to kill, learn from seed min), creation: randomly place the box, the monster will not attack you, you will not die.

Cultured pearl: according to the law of natural growth of shellfish and the principle of pearl formation, the pearl is cultivated in natural waters by using artificial technology

culture process: a small piece of oyster shell tissue was implanted into the small oyster, and then slowly cultivated. The graft formed a pearl sac, in which calcium carbonate was continuously deposited. After a period of growth, about 2-5 years, the pearl sac will grow into a pearl

1、 Methods:

1. Pearl is a substance similar to shell formed in the body of shellfish. Whether it is natural pearls or cultured pearls, it is e to the fact that when shellfish are accidentally exposed to small external irritant substances entering and contacting their mantle, the mantle is stimulated to secrete a kind of nacreous substance, which will wrap these small acrobatics layer by layer to form vegetations and form pearls after a certain period of time

Food organisms: if the food organisms in the water are abundant and the nutrition of pearl mussel is rich, the Pearl will grow well and the Pearl will grow fast with high quality. The main food organisms are phytoplankton and zooplankton

The results showed that the heat effect was directly proced by light and ventilation, which provided energy source for the survival of pearl mussel and food organisms; Light affects the physical and chemical properties of water environment; Light plays an important role in the color, reproction and behavior of pearl mussels, and it is also beneficial to enrich the luster of pearls. In a well ventilated environment, the water wave increases the dissolved oxygen in the water and promotes the movement of the upper and lower water masses and the heat transfer

Inorganic salts had direct and indirect effects on the growth and pearl formation of pearl mussel. Calcium is the main component of oyster shells and pearls (in the form of calcium carbonate). In general, the culture places of oyster are required to contain more than 10 mg of calcium per liter of water. In addition, there are magnesium, silicon, manganese, iron, etc., which are required to have a certain content

The pH value of water: neutral water (pH7 ~ 7.5) is the most suitable for the growth and secretion of nacre. The pH value of most fresh water is 6.5 ~ 8.5; The hard water is alkaline. The growth and survival of Hyriopsis cumingii will be affected if the pH value exceeds a certain limit

Water with a certain speed is of great significance for the growth of pearl oyster and pearl breeding. The proction practice has proved that the luster of Pearl bred in flowing water is better than that in still water, and the yield is also higher

Most of the substance of Pearl and shell is calcium carbonate. Pearls are composed of aragonite, while shells are prismatic layers composed of calcite

Water temperature: the growth, development, reproction and distribution of pearl oyster are directly affected and controlled by water temperature, and the formation and growth of pearl are also restricted by water temperature

Second, knowledge points:

1. China's natural freshwater pearls are mainly proced in Hainan Islands. Pearls are white, red, yellow, dark and variegated, most of which are opaque. In ancient times, people called the natural round pearl "Zou Pan Pearl"

Pearl is not a natural gem. When it is formed in some shellfish (mussels) and cannot be eliminated, its cell membrane will secrete nacreous fluid, which will continuously wrap the foreign matter layer by layer and form a pearl for a long time. Because the nacreous layer is very thin each time, a pearl is even composed of thousands of nacreous layers, which takes 3-6 years to form. Pearls are proced throughout the year, usually in December

historical functions

1. Pearl medicine has a history of more than 2000 years in China. The curative effect of pearl is clearly recorded in 19 kinds of ancient medical books, such as medical records of famous doctors in the Three Kingdoms period, collection of Materia Medica classics in the Liang Dynasty, marine materia medica in the Tang Dynasty, Kaibao materia medica in the Song Dynasty, compendium of Materia Medica in the Ming Dynasty, and Leigong's property Fu in the Qing Dynasty

In the collection of Materia Medica, Tao Hongjing of Liang Dynasty said that pearl "has the function of treating eye and skin and stopping discharge". According to the Tang Dynasty's Haiyao Materia Medica, pearls can brighten the eyes, remove dizziness and stop discharge. In the Yuan Dynasty, merchants often added honey and pearl powder to water for drinking, believing that it could not only nourish, but also prevent heat. Yuan Haowen recorded in Xuyi Jian: "the Taoshui river forms small ice in winter... Round and clean as a pearl... In midsummer, it is mixed with honey water and pearl powder."

In the Ming Dynasty, Li Shizhen paid more attention to the pharmacological effects of pearls, believing that the efficacy of pearls lies in beautifying the skin, so he wrote in compendium of materia medica: "pearls are salty, sweet, cold and non-toxic, which can calm the heart and order the eyes; Pearl painted surface, it is a good color. Apply on hands and feet, remove the skin; Dropping phlegm, removing facial spots and stopping diarrhea; In addition to children's fever, soul; Stop spermatorrhea, remove acne and treat toxin Make luster white, etc. At the same time, it also recorded a variety of methods of Pearl medicine

In the Ming Dynasty, Chen Jiru quoted yi as saying that ring the reign of Li Yan, the Prime Minister of Tang emperor Wuzong, Li Deyu used jewelry powder, realgar and cinnabar decoctions as soup, which cost about 30000 yuan per cup, and discarded the resie after three decoctions. Alchemy was popular at that time. It was believed that pearl powder, realgar and other substances, after refining, could be used for immortality

10. The output of freshwater pearls in China has been the first in the world, but the quality is not ideal. At present, nearly 10 billion juveniles and juveniles are cultivated in China every year, and 500-800 million pearl mussels are proced. If it were not for the massive death caused by clam disease, the annual proction of commercial pearl mussels and pearls would be more than twice as high as at present. Therefore, it is imperative to improve the quality and limit the yield of pearl.
