凸的

In Chapter 2,a steady permeability identification problem in elliptic equa-tions for two-dimensional orthotropic medium is considered.We construct afunctional,obtain its first and second Gateaux differential,and prove that thefunctional is strictly convex on a convex admissible function set.We seek to iden-tify the permeability by minimization of the above functional.

第二章研究了二维稳态正交异性介质的渗透率反演问题，我们构造了一个泛函，求得该泛函的一、二阶Gateaux微分，证明了它在一个凸的容许集上的严格凸性，并使用极小化泛函即变分方法来求解此问题。

In space optimization, the principle of equal-tiny increment is applied first.This classical method is used while the curve of the equal-tiny increment is raised.But in practice the curve of the equal-tiny increment is not always raised because of many uncertain factors.

在空间最优化问题的求解方法上，等微增率法提出较早，但用等微增率法要求微增率曲线是凸的，而实践中导致微增率曲线非凸的因素很多。
