The invention relates to a high-light transmittance solar photovoltaic component made with modified substrate and belongs to the technical field of thin-film solar cells. The invention aims to provide a light-transmitting flexible cell component made with flexible substrate and a solution to preparation method thereof. The invention has the key technical characteristics as follows: a stainless steel template is processed into a modified polyimide (PI) substrate (PI substrate for short), and light through-holes including guide holes and concentration holes are formed on the substrate and are distributed on stacked film layers of conducting film layers and photoelectric conversion layers in a penetrating manner. The invention has significant effects, reduces the problems of short circuit and electrical leakage due to the crystallization of the photoelectric layer processing interface resulting from laser etching of the transparent conductive film, reduces the procedure of cell surface lamination, and reduces the production cost. The process provided by the invention can significantly improve the conversion efficiency, on-load capacity and price / performance ratio of solar cells. The light-transmitting flexible solar cell photovoltaic component has a wide application range.

The invention provides a high-temperature resistant saccharomyces cerevisiae strain and a breeding method of the high-temperature resistant saccharomyces cerevisiae strain. The saccharomyces cerevisiae (Saccharomyces cerevisiae) SY-5-11L has a preservation number of CGMCC No.7377. The strain is characterized in that the ethanol yield is 13.9% (v / v) at a condition of fermenting at high temperature of 38 DEG C on the premise that other fermenting performances are not influenced, the yield is improved by 17.8% as compared with that of a parent strain. The ethanol output at the condition of fermenting at high temperature of 40 DEG C is 12.2% (v / v), and is improved by 34.1% as compared with that of the parent strain. The breeding method comprises the following steps of: performing artificial ultraviolet mutagenesis on an initial strain of the saccharomyces cerevisiae; screening out 23 forward mutant strains as a genome rearrangement library, wherein the ethanol output of the forward mutant strains are obviously raised on the condition of fermenting at a high temperature; and performing the genome rearrangement at three rounds, thus gaining the mutant strains with the maximum ethanol output under the high-temperature fermenting condition. The finally bred saccharomyces cerevisiae strain can be subjected to alcoholic fermentation at the high-temperature fermenting condition, brings no special requirements to fermenting equipment and technological conditions, and can be put into service with the equipment and conditions of general plants, thus having a wide application prospect.

The invention discloses a surface coating method for explosive particles. The surface coating method comprises the following steps of: (1) depositing vapor deposition substances at the surfaces of the explosive particles by utilizing a vacuum physical vapor deposition method, so as to obtain explosives coated by wax; and (2) depositing chemical vapor deposition substances at the surfaces of the explosive particles obtained in the step (1) by utilizing a vacuum chemical vapor deposition method. According to the coating method, the explosive particles are coated by a Parylene film after being coated by the wax, as the Parylene film has relatively strong high temperature resistance and can be used for further coating the explosives coated by the wax, the problem that the explosives coated by the wax cannot resist the high temperature is solved, and the explosive particles coated by the Parylene film after being coated by the wax can be used for casting the explosives or composite explosives.

The invention discloses a fireproof plate and a preparation method thereof, and belongs to the technical field of fireproof materials. The fireproof plate comprises a plate core, a fireproof plate body and a veneer from inside to outside sequentially, wherein the plate core comprises frameworks and filler filled between the frameworks; the filler is prepared from components in parts by weight as follows: 200-600 parts of perlite, 150-300 parts of a calcium carbide substrate, 35-45 parts of sodium silicate, 8-16 parts of magnesium oxychloride and 600-1000 parts of water; the calcium carbide substrate is prepared from components in parts by weight: 60-160 parts of CaO, 50-150 parts of kaolinite, 20-30 parts of mullite fiber, 3-5 parts of Fe2O3, 10-20 parts of polyvinyl alcohol, 30-50 parts of dolomite fiber and 600-800 parts of water. Meanwhile, the fireproof plate is prepared by the following three steps: preparation of the frameworks, filling of the plate core, and pressing of a finished product. By means of the synergistic effect of various refractory materials, the comprehensive property of the fireproof plate can be better enhanced. The multi-layer structure of the fireproof plate is pressed by pressure, so that the structure is compact, and the seal property is good.
