Formerly the arc length error for the insulation resistance instrument is defined by scale arc length. At present national standard determines that the percentage of indicated value expresses it.

The check result indicated that J9 the forecast model can control the predicted value relative error in 5%, the J15 forecast model can control in 3%.

检验结果表明J9的预测模型能够把预测值的相对误差控制在5%以内，J 15的预测模型能够控制在3%以内。

Our results also indicated that the inversion results are not sensitive to the error distributions as long as they have the same mean value and the same standard deviation.

在均值和方差相同时，上述三种不同分布的误差的反演结果相差很小。
