The present invention relates to a value-based evaluation method of oil and gas proved reserves. The present invention adopts a technical proposal that the calculation method for valuation of the oil and gas reserves is using a computer to set the reserves acquisition cost of a purchaser as a reserves asset value and as cash to flow out, and calculating and distilling depreciation as fixed assets, setting the internal return rate of the purchaser as a basic return rate, reversely calculating to obtain the reserves acquisition cost which is taken as the value of the reserves. The evaluation method has the advantages in the following four aspects: 1. the exploration benefit of different oil reserves can be analyzed according to the evaluation of the proved reserves of each area so as to provide guidance for succeeding exploration works; 2. reserves with economic benefit is selected out and invested in development with clear target in time according to the changes of global oil price, tax policy and supply and demand relationship by evaluating the value of undeveloped proved reserves, thereby providing scientific basis for the decisions of companies.

The invention discloses an antibacterial yarn, and belongs to the technical field of textile. The yarn is prepared from two or more than two of synthetic quaternary ammonium type, quaternary phosphine salt type and silver-loaded cotton fiber type antibacterial fibers in patents of CN101879466B, CN102720057B, CN103266473B and CN103835124B, one or more of cotton, viscose, tencel, dacron, chinlon, modal and soybean fiber blended fibers, and bamboo charcoal fibers by processes of opening picking, combining, cotton carding, drawing, roving, spinning and the like. A fabric made of the antibacterial yarn resists staphylococcus aureus, escherichia coli and pseudomonas aeruginosa, and is good in antibacterial property; and even if the fabric is cleaned by fifty times, the antibacterial property of the fabric can be maintained and regenerated. The antibacterial fabric not only has good antibacterial property, but also is good in spinning property, light in weight and excellent in mechanical strength; series of products such as antibacterial socks and antibacterial underwear can be developed; and skin adaptability, hygroscopicity, degree of comfort and the like are improved.

The invention relates to a hand drier with the paper feeding function. The hand drier comprises a shell, a blowing assembly, a heating net, an inductor and a control system. The shell is provided with an air outlet and an air inlet. The blowing assembly comprises a fan and a first motor. The heating net is arranged in the shell and above the blowing assembly. The inductor is arranged at the air outlet of the shell. The inductor and the first motor are controlled by the control system. The hand drier further comprises a containing box and a paper feeding mechanism. The containing box is used for containing a tissue paper box and arranged in the shell and above the heating net. An air channel for air to pass is formed between at least two side walls of the containing box and the corresponding inner walls of the shell. The paper feeding mechanism is arranged in the shell and above the containing box and is capable of drawing tissue paper out of the tissue paper box and feeding the tissue paper to the air outlet under the blowing of air, and the paper feeding mechanism is controlled by the control system. The paper feeding mechanism can automatically draw out the tissue paper and feed the tissue paper to the air outlet under the action of the blowing assembly, using is convenient, and bacterium breeding on the hands is effectively avoided after hand washing.
