Diagenetic zone and anchizone were recognized as a region rich in phyllosilicates in one-dimensional nanometer size by means of the X-ray diffraction technique.
运用X射线衍射分析技术,计算了成岩带、近变质带粘土矿物c~*方向的粒度。
For this kind of discontinuous systems ,we introduce some conceptions of the variational stability for bounded variation solutions,the Lyapunov type theorems for variational stability and variationally-asymptotically stability of bounded variation solutions are established.
介绍了本文所用到的基本概念和引理，给出了此类不连续系统的变差稳定性的定义等基本概念；建立了这类不连续系统有界变差解的变差稳定性、渐近变差稳定性两个李雅普诺夫型定理；通过李雅普诺夫函数V的构造，建立了两个李雅普诺夫型定理的逆定理，这两个逆定理的建立，表明李雅普诺夫型定理中的李雅普诺夫函数是存在的。
