Making use of this model I have a taste in Yan Shan Reservoir watershed in He Nan Province: I start on the information of the surface in this area, give every grid cell the proper parameters by distilling them from the map of how the people use soil and the map of soil type in this area; In order to get the topographical information, I add numerical value to a abundant of contour lines and points in topographical map, use the software Arc View of GIS to create Digital Elevation Models automatically, get every volume of the reservoir from the water level 99m to 117m. By using a special module of the software, I distill triumphantly the grid cells elevation value, slope value, flow direction, flow accumulation, watershed, stream network, isochrones and so on.

本文在分布式水文模型的基础上，对河南省燕山水库流域洪水入库计算模拟方面作了一些研究：从燕山水库流域的下垫信息开始着手，依据流域的土地使用类型图、土壤分布图确定每个栅格单元的土壤特性和土地利用方式，进行下垫信息的参数化，得到单元模型所需的参数值；为了提取地形信息，本文通过对流域地形图海量数据加载高程值，利用GIS软件自动生成流域内的数字高程模型，提取了流域水文模型所需要的库容曲线；通过栅格自动划分，提取栅格单元的高程、坡度、栅格流向、流域边界、虚拟河网、流量积累、等时流线面积分布等分布式水文模型的流域特征。

Phthalic acid esters are widely used in the many fields of industry. So many countries including China have come to pay attention to them and make up the codes for limiting the content in some products such as textile. By combining international codes, the thesis selects coating and textile that have close relative with people as objections. The research results are as follows:1. The thesis has established the textiles preparation method by a series of experimentations such as extraction solvent, extraction time, solid-phase extraction. The average recoveries of eleven phthalates are from 80.30% to 98.00%, and the relative standard deviations from 0.59% to 2.56%, the results show that this method is accurate and credible.2. The thesis set up the simultaneous determination of benzene, toluene, xylenes and phthalates in coatings.
