A locking device adapted to lock a shell to an installation body includes a thread connection member extending through a connecting hole in the shell and engaging a threaded hole in the installation body, a sealing ring sleeved on the thread connection member and adapted to be pressed on an installation surface of the shell to seal the connecting hole of the shell, and a gasket sleeved on the thread connection member and adapted to be pressed between the thread connection member and the sealing ring to prevent the thread connection member from being loosened. The gasket has a pair of stopping arms. An angle defined between the stopping arms is greater than 0 degrees and less than 180 degrees. A pair of top ends of the stopping arms are adapted to simultaneously abut against an outer wall of the shell to prevent the gasket from rotating with the thread connection member.

The present invention provides a method for comprehensively assessing indoor environmental quality. Pollutant concentration data used in the method is an average value calculated after sampling is performed at a plurality of positions in an indoor space, and is therefore relatively accurate, so that an excessively high or excessively low pollutant concentration at a position is prevented from impairing the accuracy of a measurement result. In the method, concentrations of pollutants are further converted into damage values, the damage values of the pollutants are converted into a total damage value based on a predetermined rule, and an air index is then calculated according to the total damage value, where the calculated air index reflects the impact of various pollutants on air healthiness. Therefore, by using the method for comprehensively assessing indoor environmental quality of the present invention, the measurement is precise, and indoor air healthiness can be comprehensively reflected.

The present invention belongs to the technical field of application of microbial secondary metabolites, and particularly relates to novel use of prodigiosin in resisting potato virus Y. Application of prodigiosin in preparing a medicine for preventing and controlling potato virus Y. The medicine for preventing and controlling the potyvirus is a liquid or solid preparation containing prodigiosin. It is clarified that PVY promotes its own replication and infection by recruiting host factor Hsp70 in the process of infecting the host, realizing virus infection and spread. Hsp70 plays an important role in the infection and replication of plant viruses. Based on the above results, it is further clarified that prodigiosin treatment can significantly increase the ubiquitination level of the plant host, promote the ubiquitination of HSP70 protein of the host, degrade or inhibit the expression of Hsp70 protein, activate the natural immune activity of the host plant.

Use of prodigiosin in resisting potyvirus

A method of reactive extrusion copolymerization of vinyl monomer consisting of (1) feeding vinyl monomer or at least one vinyl monomer together with an initiator into the first screw of twin-screw extruder, and modified resin into the subsequent screw section; (2) feeding the above monomer into the screw segment after auto-acceleration zone and feeding the initiator corresponding to the temperature of barrel and micro/nano inorganic modified fillers after the half-life period of the initiator; (3) feeding the antioxidant and anti-UV agent at the end of the polymerization, and then removing unpolymerized monomer and by-products by devolatilization of screw segment; (4) obtaining vinyl copolymer resin with a anticipated molecular weight of 5&#xd7;102 to 6&#xd7;105 from the reactive extrusion polymerization by controlling the temperature of different screw segments. The invention which overcomes the existing defects of the free radical polymerization by reactive extrusion technology, can not only meet the requirement of short stay time of reactive extrusion polymerization, combine the functionalization and high performance, but also make it possible to obtain high molecular weight polymers.
