several group number, then with b ± a, =c,c is is methyl b two vertical box between of accurate number, then with b ± a, =c,c is is methyl b two vertical box between of accurate size. Per-2~3 measurement, such as proceeds of c values are equal and equal to the design value, then the vertical installation accurate. For example a, b, and c valueswhile on horizontal vertical errors for measurement, General in iron angle code bit at measurement level points grid errors, specific method is from baseline to methyl vertical box center line distance for a,, to b vertical box distance for b, list can measured

项目设计初期准备：
1、明确电路原理，确定电路的框图，应结合本模块所要完成的功能技术指标逐项的分析
2、说明各模块的作用、模块间的连接线、电源需求，对功能模块的命名应该具有较强的可读性，命名采用英文
3、说明本模块与整个系统中其它模块的接口（包括接口的电气参数和物理参数）
原理图设计：
1、按照项目设计中所分的模块进行原理图设计
2、设计时，原理图图纸大小采用A4尺寸，
