The invention belongs to the technical field of computer accessory processing and relates to a CPU (Central Processing Unit) cooling fan. The CPU cooling fan comprises a fixing plate, an inner fixing ring covering the edge of the fixing plate, a plurality of fan blades annularly and evenly distributed on the outer side of the inner fixing ring, and an outer fixing ring fixed to the outer sides of all the fan blades. The fan blades are of a folded structure. The outer fixing ring is provided with an annular base part and upright parts protruding out of the base part, wherein outer clamping seams perpendicular to the base part are formed in the upright parts. The outer sides of the fan blades are provided with clamping claws clamped in the outer clamping seams. According to the CPU cooling fan, air can be thrown out of the side face of the cooling fan in the radial direction through the fan blades of the folded structure, the air volume is large, and the cooling effect is good.

The invention discloses an oily wastewater deoiling and modification ceramic composite coalescence material. The oily wastewater deoiling and modification ceramic composite coalescence material is composed of, by weight, 20 parts to 70 parts of activated aluminum oxide materials r-Al2O3, 20 parts to 70 parts of kaolin, 5 parts of feldspar, 10 parts to 20 parts of pseudo-boehmite, 5 parts to 30 parts of wood charcoal, and 0.1 part to 40 parts of oxidized polypropylene or polythene organic polymer materials. Prescription making, ball-milling and smashing, kneading, vacuum pugging, extrusion forming, drying and sintering are conducted to enable an aluminum oxide cellular material to be obtained, the sintering temperature is controlled between 480 DEG C and 1500 DEGC, a green body is sintered for 10 hours to 24 hours, and then the green body is covered with the oxidized organic polymer materials; the aluminum oxide cellular material is covered with the oxidized polypropylene or the oxidized polythene at the temperature ranging from 100 degrees to 680 degrees, and then the composite modification ceramic coalescence material formed by the oxidized organic polymer materials covered with the aluminum oxide cellular material is obtained. The oily wastewater deoiling and modification ceramic composite coalescence material has the advantages of being high in adsorbability, long in service life, capable of being resistant to acid and alkali, and good in deoiling effect.

This invention discloses a simple and effective microoperation nucleolus transplant method. This invention has the following steps: extruding the inject pin that has absorbed biology substance before on the ovum cell to form the transparent strip gauffer between the inject pin and ovum holding pin, then sticking and penetrating into the transparent strip gauffer with the inject pin to enter the opening of the ovum holing pin, then pulling the inject pin out from the surrounding gap of the ovum and adding the negative pressure in the ovum holing pin to absorb the pole body and object karyoplasms into the ovum holing pin, and then adjusting the place of the ovum cell with ovum holing pin to make its center at the same horizontal line with the needle-point of the inject pin, fixing up the ovum cell again, injecting the biology substance in the inject pin into the cell cytoplast or the surrounding gap of the ovum. This invention can complete the micro stoning and nucleus injecting processing at one time rapidly without special device; it has little damage to the ovum and can be used extensively in the cell project such as animal clone and transfer gene and so on.

The invention designs a preparation method of a novel long-acting sanitizer taking polyvinyl alcohol as a macromolecule retardant material. The preparation method comprises the following steps of: stirring and mixing a complete alcoholysis type polyvinyl alcohol solution with a sanitizer, namely dichloro dimethyl hydantoin, subsequently freezing for 24 hours at low temperature, taking out and thawing so as to obtain piece-shaped polyvinyl alcohol gel; and cutting the gel into small pieces and drying so as to obtain the novel long-acting sanitizer which takes polyvinyl alcohol as the continuous phase and sanitizer grains are dispersed therein. When the long-acting sanitizer is used, the polyvinyl alcohol absorbs water to swell up, however, the framework is not dissolved and disintegrated, the sanitizer is slowly released, the residual chlorine value in a water body is stable, and the slow-release time can be more than 30 days; and when dichloro dimethyl hydantoin is completely released, the piece-shaped polyvinyl alcohol retardant material can be taken out from the water body, so that the water body is not polluted.
