Abstract: Composite plating Ni-P-PTFE- nano- Al₂O₃ was made by adding nano-scaled Al₂O₃ and PTFE into chemical plating Ni-P alloy plating solution. The influences of the plating material’s hardness, abrasion and antifriction property caused by the additive amount of nano- Al₂O₃ and PTFE were studied in the paper. The results indicate that the composite plating’s hardness, wear resistance and antifriction can be greatly improved by adding nano- Al₂O₃ and PTFE into it.

Abstract: Through orthogonal analysis test analyzed three main process parameters(Acupuncture frequency, acupuncture number and acupuncture depth) on the influence of the preparation of Natural Bamboo Fiber/ Polypropylene fiber non-woven materials. The results show that when Acupuncture frequency, acupuncture number and acupuncture depth are 7.8mm\550/min\6 Composite material performance is the best; Acupuncture depth for material mechanics performance influence is the largest

Abstract: 500 pecans were measured in Henglu village of Linan city of Zhejiang province. Through measuring the tree height, trunk, crown diameter and DBH（diameter at breast height）and analyzing the correlation, the regression equation applicable to different range can be chosen.
