极值问题 meaning in English
extreme value problem
extreme-value problem
extremum problem
Examples
- A migration velocity analysis method is proposed , in which the problem of velocity analysis is converted to the problem of determining the local maximums of the defined criterion function
利用等时原理，把建立速度场问题转化为求取判别函数的局部极值问题，可以利用优化方法求解此问题。 - The conclusion that a set of extremum questions can not be solved by lagrange - multiplication is explained through analysising the extremum questions under linear target functions and linear constrained conditions
摘要通过对线性的目标函数在线性的约束条件下的极值问题的分析，得到这类极值问题一般是不能用拉格朗日乘数法求解。 - By using the inner boundary conditions , a kind of boundary value problem of three dimensional partial differential equations with discontinuous coefficients is transformed into a variational and functional one so that a difficult problem is simplified
摘要通过使用内边界条件，使一类具有间断系数的三维偏微分方程的边值问题的解法能够转化为变分与泛函极值问题的解法，使复杂方程问题简单化。 - At last , a better idea is presented : in fact , the problem of computing the shape distance between two open curves can be changed to the problem of a functional extremum , therefore , we can get the shape distance through solving an euler equation
本文在最后还证明了这样一个结论，两条平面开曲线的形状距离的计算问题可以转化为一个泛函的极值问题，于是通过解一个欧拉方程就可以求出两条开曲线的形状距离。 - In the end of this chapter , we study the wiener index for the ( m , n ) - graph . this may help for the study of the following problem : which graphs have the wiener index equal to the natural numbers besides 2 and 5 , or the extreme value problem of the wiener index
本章最后给出了( m ， n ) -图类的wiener数，这有助于探讨下述问题：以任何2 、 5之外的自然数为其wiener数的图类四北工业大学硕士学位论文的研究，以及wiener数的极值问题的研究。
