from baseline to methyl vertical box center line distance for a,, to b vertical box distance for b, list can measuredРРseveral group 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 measuredР以运算器为中心〔原始冯氏机〕。Р指令和数据都存于存储器中,计算机如何区分它们？Р解：计算机硬件主要通过不同的时间段来区分指令和数据，即：取指周期〔或取指微程序〕取出的既为指令，执行周期〔或相应微程序〕取出的既为数据。Р另外也可通过地址来源区分，从PC指出的存储单元取出的是指令，由指令地址码局部提供操作数地址。
