tata motors air powered car The "fish-type duck tail" model partially overcomes the lift of the air when the car is traveling at high speed, but it does not fundamentally solve the problem of lift of the fish. After a lot of exploration and experimentation, the designer finally found a new type of model - wedge. This type of vehicle is to tilt the body forward downward, and the back of the body is as straight as a knife, which can effectively overcome lift. The international monetary fund has strongly defended its gloomy forecast of the UK after brexit, saying a warning of a slowdown in growth is imminent. Think the dissipative structure theory, the negative entropy is to maintain and develop dissipative structure in the process of ordering "power", only the negative entropy flow to the system input, to offset the internal entropy, generated by the block system to the direction of a disorderly change, in order to maintain and develop ordering movement of the system. Obviously, this view only looks at the ordering process of dissipative structure from the perspective of pure "energy exchange". However, the nature of the material in addition to the energy the most basic characteristics, but also has many other features, such as physical properties, chemical properties and biological characteristic, social characteristic, the information characteristics, the material properties of the energy as long as the organization and cooperate well, can be used to promote the human survival and development, to maintain and develop human ordering, played the same energy orderization and objectively, and can according to the main body of the objective need of ordering energy converted into a number of standards, the dissipative structure of the ordering process is not only determined by the energy exchange, must also be by "material exchange" and "information exchange". It can be seen that some non-energy forms of the generalized preordering energy can be attached to the ordering energy and indirectly affect the preordering degree of the dissipative structure. Cave although not directly provide food for animals, for example, energy, but it can be for animals from the cold in winter, make animals reduce body heat loss, and reduce the disease incidence and mortality of animals, the objective effect and reduce the loss of food energy, improve the body of food energy use efficiency. Obviously, these not energy in the form of "ordering energy" from the objective effect does play a orderization and energy is exactly the same effect, also can promote the development of the dissipative structure ordering, plays an alternative on features, compensation, strengthen, catalytic, extension, ordering the role of energy, is a kind of indirect power energy. On the basis of "dissipative structure theory", the concept of unified axiology is put forward. The withdrawal of shares shall include the two kinds of compensation for recovery and compensation. Free withdrawal refers to the return of shares that have been allocated for free. For example, shareholders voluntarily pay back their allocated shares voluntarily. "Buy" or "buy back" means a limited company shall buy back its shares from its shareholders at a certain price. The company's reduced corporate capital could affect the price of its shares in the market. Therefore, article 143 of the company law stipulates that the company shall not acquire shares in the company. However, the following situations are excluded: (1) reducing the company's registered capital; (2) merger with other companies holding shares of the company; (3) reward the employees of the company; (4) shareholders who have objected to the merger and separation of the company made by the shareholders' general meeting require the company to acquire its shares. Company for reduce the company's registered capital, and hold the company shares of other companies mergers and shares will be awarded to the company worker of acquisition, the company's share capital shall be subject to the resolution of the shareholders' general meeting. After acquiring the shares of the company, the company shall cancel the registered capital of the company within 10 days from the date of the acquisition; Belong to a merger with hold shares in other companies the company and the shareholders for the company merger, division of resolutions of the shareholders' general meeting to dissent, requiring companies to buy the shares, shall transfer or cancellation within 6 months. The company shall not exceed 5% of the total amount of the shares issued by the company for the company's purchase of the shares of the company by awarding the shares to its employees; As regards the financing source of the acquisition, the expenses shall be paid from the after-tax profits of the company; The shares acquired by the company shall be transferred to the staff within one year.
