The results revealed that screwdrivers with triangle shaped handle could help subjects produce the maximum torque. Besides, using screwdrivers with hexagon shaped handle spent the least time, generated the minimum biceps muscle activity, and bad the least subjective fatigue rating. Moreover, wearing an anti-static glove or being barehanded can produced the maximum torque and spent the least time as well. Experiment 2 evaluates the handle diameter of screwdriver (30 mm, 34 mm or 38 mm) and operation plan. The results showed that the torque increased with the increase of the radius, the operation time and the brachioradialis muscle activity also increased with the increase of the radius.

本 研究共分为三次实验，实验一分析握把造型(八角形、锐角六角形、圆角六角形、枪型、圆角三角形)与手套(棉质手套、防静电手套、赤手)的影响，结果显示三角形造型握把可产生最大扭力，六角形造型握把的锁附螺丝时间最短、二头肌肌肉活动度最低、主观整体疲劳评比最低，防静电手套与赤手状态的扭力最大并且锁附螺丝时间最短；实验二比较握把直径(30 mm、34 mm、38 mm)与作业面的影响，结果显示直径越大扭力越大，但直径越小锁附螺丝时间则越短，且肱桡肌肌肉活动度越低。

Wing bud differentiation initiated at the early 5th nymphal instar, during which the front wing bud cells in the macropterous proliferated much more rapidly than those in the brachypterous. The hinder wing buds of the brachypterous degeneratd at middle 5th instar and finally turned out to be very little wings.

Compared with the Epoxy resorcinol-formaldehyde resin pretreatment system and Maleic anhydride pretreatment system developed by Xusigui, the 40% carbolated styrene-butadiene latex system can keep the composite"s properties and reduce the cost of pretreatment and simplify the pretreatment technology; especially to the HST 2073 latex system, the composite"s mechanics properties are improved greatly. Secondly, the composite"s comprehensive properties and interface performance are improved by reinforced with short fiber grafted with rubber in the surface. Thirdly, to simplify the production technology of composite, we add TKM-M and RF-90 as adhesive agent to the composite blended in an internal mixer, so as to the composite can be used to industry widely, then the effect of the amount adhesive agent on the composite"s properties and interface adhesive performance was studied, from the experiments the optimum amount of adhesive agent was deduced.

其中采用特软羧基丁苯胶乳预处理短纤维的方案，降低了预处理成本，相对许泗贵的低分子环氧和马来酸酐体系来说，预处理工艺大大简化了，而材料的力学性能保持良好，尤其是 HST 2073A 胶乳预处理体系，力学性能有较大幅度的提高；第二，通过对尼龙短纤维表面进行接枝橡胶分子链预处理，改善了复合材料的界面粘合性能，复合材料的综合性能也得到了相应的提高；第三，为了简化复合材料的生产工艺，使复合材料的应用得到工业化推广，我们选用TKM—M和RF—90长效增粘剂，直接加入短纤维橡胶复合材料中，采用密炼工艺，探讨了增粘剂的用量对复合材料界面粘合以及性能的影响，得出了增粘剂在复合材料中的最佳用量。
