摘要： A virulence factor FsPL gene from the sugarcane pokkah boeng disease and use thereof are provided. The virulence factor FsPL gene from the sugarcane pokkah boeng disease has a sequence set forth in SEQ ID NO: 1. The present invention reveals a gene FsPL that is related to the pathogenicity of F. sacchari. Preliminary analysis shows that the deletion of the gene affects the ability of hyphae to penetrate and further affects the pathogenicity of pathogens. This provides a basis for the molecular mechanism of the pathogen infection and pathogenic process.

摘要： A method for quantitative analysis of a cavity at the top of a concrete-filled steel tube is disclosed. By substitution of the determined inner radius of the steel tube, the thickness of the steel tube wall and the propagation speed of ultrasonic waves in the steel tube and in the concrete, the propagation time of the ultrasonic wave between the top and the bottom of the concrete-filled steel tube enables calculation of the height of the cavity. The method can be used to quantify the cavity height at the top of the concrete-filled steel tube, with small relative errors and high accuracy.

摘要： To promote anaerobic digestion and delay calcification, one or more signal molecules are used to regulate the microenvironment of anaerobic granular sludge. In the process of anaerobic granular sludge treatment of papermaking wastewater, AHLs (N-acyl Hyperserine Lactones) are added to papermaking wastewater before the papermaking wastewater enters the anaerobic reactor. This may occur when the proportion of microorganism in anaerobic granular sludge VSS/TSS is less than 0.6. Further, the addition of the one or more signal molecules changes the community structure of the bacteria and methanogens, promoting anaerobic digestion and delay calcification. Additionally, the microenvironment of granular sludge is regulated by adding one or more micro-signal molecules to improve the number of bacteria susceptible to calcification, improve the anaerobic digestion rate of sludge that has not been calcified, and delay the calcification rate.

摘要： The invention discloses a method for preparing high-purity chlorine dioxide by using methanol and hydrogen peroxide as reducing agent. The method comprises: concentrated sulfuric acid and sodium chlorate solution are injected into the generator to form the reaction mother liquid. The reaction mother liquid shall be maintained a certain acidity, temperature and sodium chlorate content, and then it is reacted with the reducing agent (methanol and hydrogen peroxide) to produce chlorine dioxide gas and by-product sodium sulfate. The chlorine dioxide gas is cooled and absorbed by low temperature chilled water to obtain an aqueous solution of chlorine dioxide, and by-products are recycled. The chlorine dioxide solution produced by the aforementioned method has a 60-70% reduction in the Cl2 content and 14-20% reduction in sulfuric acid consumption than that of the chlorine dioxide produced by using a single methanol reducing agent, and the by-product produced is sodium sulfate, not sodium hydrogen sulfate, so neutralization reaction treatment is not required.
