辅助系统

The DTM for automatic-design of thruway was put forward by Prof. Miller in 1956. Since then , the DEM is used for design of various circuit diagram, and for account of area, cubage, gradient of various project, and for estimating visibility from point to point; for rendering contour, grade-graph, aspect-graph, solid model; for making orthographic image and repair map in the Topography; for assistant data to classify in the Remote Sensing; as basic data in the GIS, for analysis and layout actuality of using soil, for disaster prediction; for navigation, guiding missile in the military affairs.

美国麻省理工学院Miller教授为了高速公路的自动设计于1956年提出了数字地面模型的概念后，DEM被用于各种线路的设计及各种工程的面积、体积、坡度的计算，任意两点间可视性判断及绘制任意断面图；在测绘中被用于绘制等高线、坡度坡向图、立体透视图，制作正射影像图与地图的修测；在遥感中可作为分类的辅助数据；它是地理信息系统的基础数据，可用于土地利用现状的分析、合理规划及洪水险情预报等；在军事上可用于导航及导弹制导；在工业上可利用数字表面模型DSM或数字物体模型绘制出表面结构复杂的物体的形状[2]。

Each male ratwas paired with 2 female rats in proestrus when administration terminated. Femalerats were examined the next morning for the presence of sperm in vaginal smears andunderwent a cesarean section on day 13 of gestation. Then the reproductive indiceswere calculated as follows: copulation index, pregnancy index, and fertility index,which can evaluate male fertility directly. The sperm motility and morphology wereevaluated by computer-assisted sperm analysis, moreover, the caudaepididymal sperm ultramicrostructure were analyzed by transmission electronmicroscope, which can evaluate the influence on sperm maturation bydutasteride ; sperm survival rate was assessed by SYBR-14 and propidium iodidefluorescent staining; serumal dihydrotestosterone and testosterone of ratswere detected by enzyme-labeled immunoassay, which can evaluate the effecton androgenic levels; the weights of testes and epididymides, were determined byprecise electronic balance; histological examination of above tissues were evaluatedby HE staining and TEM, which can evaluate treatment on histology of reproductiveorgans by dutasteride.
