order of separation meaning in English

分离顺序

Based upon practical engineering applications , the variant separating - variable algorithms of hyper - surface fitting for arbitrary multivariate scattered data are presented by separating positional variables in a spatial domain from certain physical variables such as time , mach number , angle of attack and so on , followed by their comparison . when compared with existing scatted data interpolation algorithms , the new ones are more effective . a sufficient condition to exchangeable order of separation is obtained and order of continuity on the hyper - surfaces above is discussed
三、以实际工程应用为背景，将具有某种物理意义的量(如时间、 ma数、迎角等)与空间位置变量分开处理，给出任意散乱数据超曲面拟合变量分离的各种算法，对它们进行了算法的分析比较，获得了分离次序可交换性的充分条件，给出了变量分离法构造的超曲面的光滑阶。
