Then, on the basis of leastsquarescollocation, an iterative model is given to dispose the refraction error, and the effect is satisfactory.
在此基础上，利用最小二乘配置原理构造了处理折光误差的迭代平差模型，取得了良好的效果。

The leastsquarescollocation also be quite useful for analysing the station displacement in a network.
文中所用的新、旧网的最小二乘配置法对于点的位移分析也有很大的实用意义。

Using this model, the airborne gravity measurement test data is downward continued based on leastsquarescollocation and is compared with known ground gravity data.
