| 摘 要： | 在普通物理实验中 ,已理想地消除了产生系统误差的原因 ,但在相同条件下多次重复测量同一物理量时 ,还会发现各次测量值之间有差异 ,由此而产生的误差的绝对值和符号以不可预定的方式变化着 ,这就是随机误差 (又称偶然误差 ) ,因此对误差的计算主要是随机误差的计算

| Abstract: | In the experiment in basic physics,though the systematic errors have been gotten rid of successfully,the result of the repeated measurements of the same physical quantity under same conditions are of a little difference.Thus the ablsolute value and the sign of errors produced are always changing unexpectedly. This phenomenon is called random errors.So the measurement of errors is mainly that of the random errors. |
