通过显微镜下观察、电子探针、X射线粉晶衍射等常规岩石测试方法,并结合阴极发光,得出天蓝玉与翠绿玉的绿色部分主要为含铬的云母;绿粉玉中的绿色部分颜色产生与绿帘石有关,由于Fe的含量比较高,造成了绿色部分比较暗淡,不鲜艳,颜色较浅;绿白玉中绿色部分,经矿物分析主要为透辉石,Cr、Fe含量都比较高,暗绿颜色成因与透辉石有关。

The comparison between the obtained EC50 values and toxicity data from the literature points out the good agreement between the BOD bottle test (Raphidocelis su.) and those of nine widely used test methods, i.e., Fathead minnow, Vibrio fi., Microtox, Polytox, Spriotox, Shk1, Activated sludge, Daphina ma. and Tetrahymena.

Many scholars have studied these respects and given many important results, for example, the Hupperts famous theorem, namely, a finite group G is supersolvable if and only if every maximal subgroup of G has prime index; a finite group G is nilpotent if and only if every maximal subgroup of G is normal in G; a finite group G is solvable if and only if every maximal subgroup of G is c-normal in G (See it in [70]); etc.

The second chapter is the main part of this paper, in which the formulation of the Riemann boundary value problem of non-normal type on the real axis, the solution method of homogeneous problem, the relation between the two kinds of different derivatives and the inhomogeneous problem will be thoroughly given. In this paper, the solution and the solvability of the Riemann boundary value problem of non-normal type on the real axis will be given. Furthermore, it is shown that the twokinds of derivatives of the function Ψ are existing and equivalent in the case ofthe solution about the original problem, therefore, we get uniformly Hermite interpolatory polynomial. The relation between the two kinds of different derivativesof the function Ψ are similar for smooth closed contours by means of the same proof.

In the last chapter, on the basis of theories in paper [4, 5], the notions of strong mixing, weak mixing, generator and expansion of the variable-parametric dynamical system are introduced, it turns out that in variable-parametric dynamical system strong mixing implies weak mixing and then implies transitivity; it is proved that if and both are variable-parametric dynamical system, F conjugates with G , the members of F are communicate with each other and the members of G are also communicate with each other, what's more, they are both homeomorphism, then F is strong mixing implies G has the same properties; futhermore, we prove that F is strong mixing implies F Devaney chaos in the sense of modification in variable-parametric dynamical system and that F Devaney chaos in the sense of modification if and only if G Devaney chaos in the sense of modification when semi-conjugate with and they both are communicate and homeomorphism; at last, we illustrate that F has generator if and only if it has weak generator, and we also prove that if F is expansion, then F has generator.

在第三章中,我们在文[4,5]的基础上,提出了变参数动力系统拓扑强混合、拓扑弱混合以及变参数动力系统的生成子、扩张的概念;证明了变参数动力系统拓扑强混合蕴含拓扑弱混合,进而蕴含拓扑传递;证明了:如果,为两个变参数动力系统,F与G拓扑半共轭,F两两可交换,G两两可交换,它们均为同胚映射,那么F拓扑强混合,则G也有同样的性质;本章还证明了变参数动力系统拓扑强混合蕴含F在修改的意义下Devaney混沌;在此基础上得出了:如果变参数动力系统与变参数动力系统拓扑半共轭,它们都两两可交换,并它们均为同胚映射,那么F在修改的意义下Devaney混沌当仅当G在修改的意义下Devaney混沌;得出了F有生成子当仅当F有弱生成子;如果F是扩张的,则F有生成子。
