摘 要:电子计算机模拟实验研究证明真误差函数式 W=Δ1+Δ2+…+Δn =[Δ]式中W量虽是随机量,但有随n的增加而统计增加的趋势。作者建议以W的绝对值的平均值。 |W|M=E(|W|)=4/5δn1/2作为W随n增加趋势的指标。同时实验证实了σW2=[WW]/N和σW2=σ2·n两式的结果是一致的。
Abstract: It is proved from the random simulating test with a computer that real error function W has atendency to increase statistically with the increase in the number of real error n. The author hasrecomrnended that the average of the absolute valule of W be considered as an index of the tendencyof W with the increase of n. At the same time, it has also been proved from the test that the law of error propagation is correct.
