例句与用法

1. In chapter three the simplex method is developed in detail , and in chapter four the initiation of the simplex method by the use of artificial variables and the problem of degeneracy are discussed
   在第三章详细建立单纯形法，在第四章介绍利用人工变量法初始化单纯形法并讨论了退化问题。
2. This paper presents a simple approach to working out the basic feasible solution directly in linear programming , which avoids introducing artificial variables , decreases memory , and generally gets a better basic feasible solution at a quicker speed
   摘要本文给出直接求线性规划问题基可行解的一种简易方法，该方法既避免了引入人工变量，减少存储，一般又能较快地得到一个较好的基可行解。
3. The vertical loads , horizontal loads and other factors relevant to the behavior of pile , as natural or artificial variables , are variant in statistics . but statistical variability of vertical loads , horizontal loads and other factors , is seldom applied to the study of behavior of pile under inclined loads by engineers
   不论是荷载还是其它的影响桩受力性能的因素,都是受自然或人为影响的变量,都存在着数理统计上的变异性,但是人们在倾斜荷载桩的工作性能研究上却很少考虑它们的变异性。
4. In contrast to existing simplex method , this method has several peculiarities as follows : to begin with , applying it to solve linear programming problem . one need n ' t introduce any additional variable such as relaxing variable , artificial variable and other parameters , so that calculation is subtracted on a large scale . in addition to this , as a result of its higher degree of structuralization , this algorithm can be more easily transformed into program language and , of course , more quickly performed by computers
   与现有的单纯形法相比，新算法具有如下主要特征：第一，求解过程不需要引进诸如松驰变量、人工变量等参变量参与运算，计算量大大减少了；第二，新算法较单纯形法的结构化程度高，更容易转化为程序语言，进而在计算机上更快地得以实现；第三，新算法在运算过程中不会引起摄动现象。
