least square approximation

基本解釋

Since the gradient of the velocity is high in the mould, the control method of simulation points is applied in the least square approximation.
由于口模內(nèi)速度變化梯度較大，采用最小二乘近似節(jié)點控制方法來控制近似效果。
In this paper, a method of least square approximation was introduced to predict the trend line of carrier movement. Then the yarn paths were analyzed systematically.
