The invention includes a composition for stabilizing chlorinated water to sunlight decomposition, and methods of preparing compositions. The composition is a slurry composition of a monoalkali metal cyanurate, of low viscosity. Two methods of preparing the slurry are described, in which cyanuric acid or cyanuric acid wetcake is mixed with a monoalkali metal base. One method dry blends cyanuric acid or cyanuric acid wetcake with a monoalkali metal base. The invention also describes a method of preparing a dry, solid monoalkali metal cyanurate.

The present invention relates to a gene construct which is capable of achieving efficient production of an antimicrobial peptide in a microorganism, and a method for efficient mass production and separation of an antimicrobial peptide using the same. The gene construct of the present invention has a translationally coupled configuration of two independent and separate cistrons which encode an acidic peptide and a basic antimicrobial peptide, each having an opposite charge, under the control of a single promoter. The translationally coupled acidic peptide and basic antimicrobial peptide undergo charge-charge interaction simultaneously with expression thereof to neutralize the potential cytotoxicity of the antimicrobial peptide, resulting in prevention of antimicrobial peptide-mediated killing of host microorganisms. In addition, a conjugate of the acidic peptide and the antimicrobial peptide can be separated without chemical or enzymatic treatment. Therefore, it is possible to achieve easy mass production of antimicrobial peptides from recombinant microorganisms.

The invention discloses cuprous oxide powder and a preparation method thereof. The preparation method of the cuprous oxide powder is as follows: smelting pure copper to a molten state, directly atomizing the copper in the molten state in a nitrogen and oxygen mixed atmosphere for oxidation reaction of the copper and oxygen to obtain the cuprous oxide powder. During production of the cuprous oxide powder by the atomization method, the nitrogen and oxygen mixed atmosphere is introduced for high-temperature oxidation of the pure copper and the oxygen in the atomization process to prepare the cuprous oxide powder, meanwhile because of lack of oxygen, cuprous oxide cannot continue to react with the oxygen to form copper oxide. The preparation steps of the method are efficient, fast and convenient, production steps are saved, the production method of the cuprous oxide powder is broadened; and the cuprous oxide powder prepared by the preparation method has relatively concentrated and uniform particle size distribution and excellent physical properties, and is easy to use later.

The invention discloses sanitary towel partner trousers which comprise a trousers body composed of a single elastic inner core non-woven fabric, and the elastic inner core non-woven fabric is formed by compounding two non-woven fabric layers, a plurality of elastic fibers clamped between the two non-woven fabric layers and a plurality of point-shaped connecting lines perpendicular to the elastic fibers.
