虽然每个公式中只有少数几个系数，但是本文中所有公式的平均误差都小于2%。

With a few arbitrary constant for every formula, the average errors are less than 2% for all the formulas in this thesis.

中晚稻单产灾损率的预估误差的绝对值在0.02~3.77个百分点，平均误差为1.9个百分点，预估精度较高，灾损评估方法可行。

The absolute values of the prediction error of the middle-late rice were between 0.02% and 3.77%, the average error was 1.9%. The precision was high, so the damage assessment method was feasible.
