In order to figure out the use of compression in the wood preservation aspect, the authors compared the compressed wood samples pretreated with hot water bath or water spraying and compressed preservative-treated wood, which was treated with ammine copper quat-type D preservative solution. The liquid absorption and recovery rate of compression deformation of the compressed wood were determined, as well as the surface hardness, distribution of density and CuO retention in the thickness direction of CPW.

摘要为研究压缩处理在木材防腐方面的应用，该研究测定了经过不同水浴和喷水预处理后的径向压缩木材在胺溶铜季铵盐--D型防腐剂中浸泡后的吸液量和变形回复率，并测定了由此制备得到的压缩防腐木的表面硬度、厚度方向上的密度分布和CuO保持量分布情况。

Multistep deposition process has been adopted in the preparation of superfine inorganic composite antibacterial powder, Ag~+ as crystal nucleus, packed outside by the hydroxid and phosphate precipitate of Ti and Zr elements etc., The optimal process conditions have been found from one-factor influence tests and multi-factor orthogonal test,and the optimal process conditions were: Ag iron was imported by silver ammine, and then 100ml Titanyl sulphate solution mixing with zirconium sulfate keep hot at 90 ℃ for 30 mins, and the Zr/Ti ratio is 0.15,and Na_2HPO_4 was added in the end.
