摘要
由于测量工具、计算工具和计算方法等方面的原因,数据的计算值与实际值之间总是存在一定差距,即误差。文章分析了数据误差产生与传播途径,通过例证,归纳出了多种缩小数据误差、提高计算精确度的措施。
Due to the differences in measuring instruments,calculating tools and methods,differences or errors always exist between the calculated value and the actual value.The appearance of errors and the way of spread were analyzed in the article.By means of illustration,several measures for minimizing data errors and improving calculation precision were summed up.
