Thirteen undergraduates(7 male and 6 female)participated in manual performance evaluation studying with barehand and with the simulated spacesuit glove through strength,fatigue,tactile perception,range of motion and dexterity 5 studying indices(28 testing indices),and the 28 testing indices were optimized by using statistics and knowledge of anthroposomatology.

航天员在舱外的作业任务种类繁多，又兼有太空失重和超高低温等恶劣因素存在[1，2]，这些都给舱外航天服手套的手动作业工效评价提出了较高的要求。O′Hara等[3~7]结合空间飞行部分情况，在地面上对手动作业工效评价的力量、疲劳、活动范围、触觉感知、灵活性5项工效指标开展了较全

The contents of Fe, Mn, Cu, Zn and Ni of all the organs in Canarium album Raeusch.

所测橄榄品种各器官中的Fe、Mn、Cu、Zn、Ni的含量在一般植物体的正常含量范围之内，但Cr含量远远超出正常含量范围，表明橄榄是一种富集Cr植物；由于生物体的有机铬是有效的抗癌和降脂成分，因此橄榄超高含量的Cr可能与橄榄抗癌和去脂减肥药用作用密切相关。

Belonged to the normal contents of the trace elements in plants, but the content of the Cr was far higher than that of the general plants, which suggested that Canarium album Raeusch. be of Cr hypertolerant plant. Because organic Cr in organisms was the effective element with the effects of anti-cancer anticancer and fat reducing, the ultrahigh content of Cr was probably related to the effects of anti-cancer anticancer and fat reducing of Canarium album Raeusch..

Carbon black and capsulated amorphous phosphorus were applied as modification agents of ultrahigh molecular weight polyethylene to improve the flame retardant property.

介绍了利用炭黑和胶囊化红磷作为阻燃剂对超高分子量聚乙烯进行共混改性的研究，比较了不同种类炭黑的作用效果。

In order to extend its applications in various fields, capsulated amorphous phosphorus was used as flame retardant of ultra-high molecular weight polyethylene, and four kinds of carbon blacks were selected as antistatic agents.

针对超高分子量聚乙烯阻燃、抗静电性能差，不能满足某些场合应用需求的现状，利用微胶囊化红磷和发黑作为改性剂，对UHMWPE进行改性，其氧指数达到24.2％～29.5％，表面电阻率降到1×10~9Ω以下，实现了阻燃、抗静电的目的，并且基本保持了UHMWPE原有的优异耐冲击与耐磨性能，提高了它的热变形温度与弯曲强度，从而拓宽了UHMWPE的应用范围。
