In the paper, the author did some research on the Graphical Model Platform of MGMS, the subsystem of MGMS. The GMP mainly has four functions as follows. The first aspect is the drawing function of micro-grid power system, including drawing power equipment, selecting power equipment and delete power equipment etc. The second aspect is the function of modifying parameters of power equipment. The third aspect is the function of topology automatic identification of the power system. The last aspect is advanced application function of GMP, including topology analysis and the real-time monitoring of the micro-grid power system which is in operation.

GMP主要要实现以下四个方面的功能：首先是设备绘图功能，包括鼠标绘制设备图元、鼠标选中设备图元、删除设备图元等基本的人机交互绘制微电网接线图功能；其次是修改已建设备的属性；再有是建立与建立的图形系统一致的电力系统网络模型，即对已绘图形的网络拓扑自动识别；最后是在此基础上的高级应用功能，包括电力系统网络拓扑的着色分析和运行数据的实时显示功能。

Here, we examined the genetic diversity and phylogeographic structure of domestic goats by determining mitochondrial DNAand microsatellite DNA. The genetic diversity of five goat breeds including Angora goat, Shandonglaiwu black goat, Hanshan white goat, Taihang goat and Wuzhumuqin goat was surveyed using twenty-five microsatellite loci,The UPGMA phylogenetic trees constructed with the Dcoa genetic distances between the five goat breeds supported a closer relationship between Hanshan White goat and Wuzhumuqin goat.

本研究利用微卫星和线粒体DNA分析山羊的遗传多样性及系统进化关系，用25个微卫星位点分析了安哥拉山羊、山东莱芜黑山羊、罕山白绒山羊、太行山羊及乌珠穆沁绒山羊这5个山羊品种的遗传多样性，共祖遗传距离的UPGMA聚类表明遗传距离和地理距离是一致的，如内蒙的罕山白绒山羊和乌珠穆沁绒山羊聚到一起。

In the third chapter, Based on the Bloch equation and with the use of methoddevoloped in chapterl, the level shifts of two-level atom are calculated under theinteration of classical and quantized field. An analytic formula of level shift of atomin AC Zeeman effect is obtained.

从本章给出的计算方法中，还揭示了当一量子系统受到一与时间相关的微扰并发生跃迁时，微扰引起的能级移动是一个与跃迁同时发生的瞬态过程，跃迁和能级移动是同一过程的两个方面。
