Then, the distance between point of STL model reconstructed by CT slices and CAD model is got by UG function and the error distribution is also got.

然后利用UG函数求取出CT切片重构的STL模型上的点到CAD模型的距离，得到误差分布。

For special earthquake location research, it also provides function to draw two dimensional isogram drawings of earthquake location error and distribution drawings of three dimensional error.

对于专门进行地震定位研究的工作，还提供了绘制地震定位误差二维等值线图和三维误差分布图的功能。

The ARMA model was used to describe the prior distribution of observed discharge and the ar model was adopted to simulate the likelihood function of forecasting error.

该模型采用ARMA模型描述实测流量的先验分布，采用AR模型模拟预报残差的似然函数，并假定先验分布和似然函数均服从正态分布。
