Pedestrians at the street dress relatively clean , only design s dull somes , wear leather shoes little people , almost all the persons wear bule rubber overshoes 街上的行人穿得比较乾净，只是花色单调了一些，尤其是穿皮鞋的人少，几乎所有的人都穿蓝色胶鞋。
Low - level waste ( llw ) consists of daily refuse such as paper , gloves , plastic containers , disposable overalls and overshoes with low radioactive contamination 低放射性废物包括受到轻微辐射污染的日常废物，例如纸张、手套、塑胶容器、用完即弃的罩衣和套鞋。
Then the voice said something more , demyan answered something , and the steps in thick overshoes began approaching more rapidly up the unseen part of the staircase 后来还听见某人说了一句什么话，杰米扬应声回答，穿着厚皮靴的脚步声沿着望不见的楼梯转弯的地方更快地向近处传来。
To avoide electric shocks , you should wear protective work cloth , protective gloves and insulating rubber overshoes according to regulations , and keep yourself dry and clean as well 为了防止触电事故的发生，除按规定穿戴防护工作服、防护手套和绝缘胶鞋外，还应保持干燥和清洁。
To avoid electric shocks , apart from wearing protective work overalls , protective gloves and insulating rubber overshoes according to regulations , it is also advised to keep dry and clean 为了防止触电事故的发生，除按规定穿戴防护工作服、防护手套和绝缘胶鞋外，还应保持干燥和清洁。
To avoide electric accidents , you should wear protective work cloth , protective gloves and insulating rubber overshoes according to the regulations , and keep yourself dry and clean as well 为了防止触电事故的发生，除按规定穿戴防护工作服、防护手套和绝缘胶鞋外，还应保持干燥和清洁。

Based on a real applying project , the deep study has been made theoretically on " cad / cam integeration for rubber overshoes " in this paper , which will raise the level of designing and manufacturing rubber overshoe mould 本文通过一个实际应用项目? ? “胶鞋模具cadcam一体化”的系统开发，对此进行了理论研究和具体实施，从而提高了胶鞋模具的设计与制造水平。
Up till now , in some middle - small production enterprises of rubber overshoes in our country , the level in designing and manufacturing rubber overshoe mould is still relative backward , main mode of manufacturing mould is manual operation and its quality and grade is not high . its production period is long , which more and more difficultly meets the needs of market 目前，在我国的一些中小型胶鞋生产企业中，胶鞋模具的设计和制造水平还相对落后，仍然是以手工作仿的加工为主，加工手段落后，质量差，档次低，生产周期长，越来越难以满足市场的需要。
Secondly , to counter contour curve for large sole of rubber overshoes , the way of linear circle arc spline of two dimensions curve fitting has been raised in this paper and autocad has meanwhile been applied in cad / cam integeration system of rubber overshoes mould , and also a whole set of software and hardware technique developed , and the selecting way for optimizing tool path worked out . this way may make nc machining free running minimun 其次，针对胶鞋大底的轮廓曲线，对圆弧样条进行了深入研究，提出了二维曲线拟合的线性化圆弧样条方法；同时将autocad应用于胶鞋模具cad / cam一体化系统中，成功地开发了一整套相应的软硬件应用技术，提出了刀具轨迹优化的动态选择法，以便使nc加工的空行程相对极小化。
