The same situation is on the problem of ectogenesis after man's death, which also face the same problems too. it will bring out the assault to the existing social family's structure, and the materialization of child, the violation of the individual's right to make his own decision, and the violation of " human nature dignity " principle, if the law allow to ectogensis after man's death .

同样的情形，在取后进人工生殖之问题探讨上，也面同样的问题，开放后人工生殖，也会对现有的社会家庭结构产生冲击，亦有是否为纯粹满足大人的欲望而将小孩子物化的隐忧，及进后人工生殖得过程中是否尊重个人「自主决定权」之使，有无违背「人性尊严」原则，，，等等问题。

This paper is devoted to solving linear saddle point problems, Specifically, We consider nonsymmetric systems, written as usual in block form, where the upper left block is an invertible linear operator with positive definite symmetric part. Such saddle point problems arise, for example, in certain finite element and finite difference discretizations of NavierStokes equations, Oseen equations, and mixed finite element discretization of second order convection-diffusion problems.
