离散问题 meaning in English

discrete problem
discrete variable problem

The mathematical model based on gis is built , and the interface program of data conversion between the two models is designed , and the spatial discretion of the computational domain is discussed
在此基础上，建立了基于gis的泥沙数学模型，设计了两种模式数据交换的接口程序，探讨了泥沙模型计算域空间离散问题。
This method connects the discrete points processed in the level set method to form a smooth curve , thus transforms the discrete problem to continuous one . constraint entry is added to the curve according to the actual demand , and satisfactory result is obtained in experiments . the results show that the algorithm is effective in the actual applications
基于链码的水平集方法把原先水平集方法中处理的离散点,利用链码易于表示曲线的特点,连接成一条光滑的曲线,这样就把离散问题转化为连续问题,利用曲线的连续性和光滑性,根据实际问题的需要,对曲线加入外部约束项控制,在实验中获得了满意的结果,在实际应用中达到了预期的效果。
