去除转移后LED薄膜中过渡层后，GaN层受到的张应力变大，而铟镓氮层受到的压应力基本不变。

In the upper layer of the crust, low strain energy density is found on both sides.

此外，由计算得到的应变能密度分布图可见，龙门山断裂带在上、中地壳层中均位于宽度相同、其走向与龙门山断裂带走向一致的高应变能密度带中，在上地壳层这个带的东西两侧则是应变能密度较低的地区，而在中地壳层，其强度在断裂带东侧逐渐向东衰减，西侧应变能密度高，而东侧应变能密度较低。

Arc-glow plasma depositing technique is a new surface coating method. With the help of vacuum arc discharge, a cold cathode arc source continually emits ion beams of coating elements with high currency density and high ionizing ratio.Upon the ion bombard and diffusion work on, the surfaces of the parts form deposited layers, diffusion layers. In this study, a commercial magnesium alloy AZ91 was coated with Ti film layer.

加弧辉光离子渗镀技术将辉光放电与弧光放电有机地结合起来，利用辉光放电空心阴极效应使工件迅速升温，同时在真空容器壁上设置一个或多个金属阴极电弧靶源，利用真空电弧放电而不断地发射出高能量、高电流密度、高离化率的欲渗金属离子流，依靠扩散和离子轰击作用快速渗入工件表面层，在工件表面可以形成渗层、镀层、渗镀结合层。

The results showed that the changes of the types were not caused by new cell mutation, but by translocation of the different cell types of variegation. The changes of division direction of white cells and green cells resulted that some of the green epidermal cells translocated into the second layer and it pushed furthermore the origin white cells of the second layer into the third layer, so that the variegation altered.

Pollock'突变型异化不是由于细胞突变形成，而是由于质体突变型白色细胞和原型绿色细胞在生长发育过程中相互竞争转轨所致，即白色细胞和原型绿色细胞改变了分裂方向，部分表皮绿色细胞进人第二层，挤压第二层白色细胞转轨进人第三层，导致细胞类型的移位，从而形成异型斑。

The sixth part: Studies on the dynamic changes of soil retention function value of ecosystem in YUYANG District. Utilized ERDAS8. 5 to interpret the remote sensing image and get LUCC data and vegetation information of YUYANG District. Utilized R2V5. 5 to digitize administrative map, topographic map, vegetation picture, soil distribution map and meteorological website map. Utilized ARCINFOR8. 3 to change every digitization layer to the same projection, to generate Tyson polygon, to structure DEM and do vector polygon overlay. Utilized ARC VIE W3. 3 to obtain the grid data topographic slope and slope length from DEM data of YUYANG District, and then, turned every coverage layer into grid layer and do grid polygon overlay to gain data about dynamic changes of value of soil retention of ecosystem in YUYANG District, at last, the author analyzed the features of the spatial-temporal changes and its reason.The seventh part: Studies on the dynamic changes of fixing drifting sand against wind function value of ecosystem in YUYANG District.

第六部分：榆阳区生态系统土壤保持功能价值动态变化研究；利用ERDAS8.5对遥感数据进行解译获得榆阳区土地利用数据和植被信息，利用R2V5.5数字化榆阳区政区图、地形图、植被图、土壤分布图及气象站点分布图，利用ARCINFOR8.3对各数字化图层进行投影转换、泰森多边形生成、DEM构建和叠加分析，利用ARCVIEW3.3从DEM数据中获取榆阳区的坡度、坡长面域数据，并将上述各图层格网化，然后通过栅格图层叠加分析和代数运算获取榆阳区生态系统土壤保持功能物质量和价值量时空动态变化数据，最后分析了其变化的时空特点及形成原因。

Firstly, a scalar and vector potential analysis models of tooth-layer magnetic field in a two-degree-of-freedom motor is developed, which is the same as standard hybrid step motor. By applying the finite element method, the distribution of the tooth-layer magnetic field is studied in detail. It provides an effective means for further calculation of performance and parameters of the motor.
