However, chloroplast matK genes are indispensable since in nonphotosynthetic parasitic plant, Epifagus virginiana and fren, Adiantum capillus-veneris which chloroplast genome has rearrangememt, the chloroplast matK is functional even being a free-standing from with dismissed trnK exons.The chloroplasts of Psilotum, moss and liverworts all have trnK5'-matK-trnK3' structure, but it is found that matK is a pseudogene in hornwort Anthoceros formosae. Little is known in other lower land plants, it is the purpose of this thesis to examine the presence of chloroplast matK gene is these taxa.

叶绿体trnK5'-matK-trnK3'的结构在高等植物相当一致，但先前研究发现两个matK脱离trnK而存在的例子，像是叶绿体严重退化的寄生植物Epifagus virginiana及因叶绿体基因重组而导致trnK外显子丢失的铁线蕨，它们的matK仍然具有完整的开读框，显示了matK的确十分重要而不可缺失，藓苔类和松叶蕨也被证实具有trnK5'-matK-trnK3'的结构，但是在角藓中却发现其matK是伪基因。

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。
