Because sexangle microscopic image of wood cells can represent most shape features of wood cells,this paper had accomplished the simulation of microscopic image for wood cells of regular normal hexagon,regular long hexagon changeable hexagon as per Early and Late.

由于六角形木材细胞显微图像，可以代表木材细胞的大部分的形状特征，本文完成了对规则正六角形、规则长六角形、按早晚材变化的六角形木材细胞显微图像的仿真。

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。
