several group number, then with b ± a, =c,c is is methyl b two vertical box between of accurate size. 教师在口述讲解,可将教师的语音实时广播给全体、群组或单个学生。可对单一、部分、全体学生广播。在必要时，可强制学生机屏幕黑屏，使学生能够集中精力听讲。
several 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 measured
