钢丝传送带。第1部分：一般用途传送带的设计、尺寸和机械要求。
Steel cord conveyor belts - Part 1: design, dimensions and mechanical requirements for conveyor belts for general use.
一般地说，钢质棒料、锻件、铸件等只经一次粗切削和一次精切削即可达到所要求的形状和尺寸。
Generally speaking, bars of steel, forging, castings, etc. are machined to the required shape and size with only one roughing and one finishing cut.
由于销孔尺寸、形状和位置精度及粗糙度的要求都很高，一般都需要设计并制造高精度的镗头。
Because of the high requiring of the size, shape, position precision and roughness of pinhole, a high precision boring cutter is required to design and manufacture.
一般来说，MEMS器件具有毫米级的整体尺寸和微米级的局部尺寸，因此，测试技术要求尽可能同时具有大视场、空间分辨率高的性能。
In general, MEMS devices are mm size in overall and um size in local. Thus, the testing technical is required to have high spatial resolution and large field of view.
