实现与MapObject配合的鹰眼图功能，需要有Mapobject控件支持。-MapObject realize with the Eagle Eye diagram with function, the need for support has MapObject controls.

处理dem的东东，不错，请大家试用 -dem handle the Eastern, yes, please probation probation

32×32的寄存器堆，它有32个32位的寄存器、两个读端口和一个写端口。该寄存器堆由3个层次共5个模块构成，最低层次的模块是D触发器，中间层次的模块包括32位寄存器、5位地址译码器、32选1多路选通器，顶层模块是寄存器堆模块。设计采用行为建模和结构建模相结合的方法，先用行为建模方法建立低层模块，然后再用结构建模方法搭建高层模块。-32 × 32 of the register file, it has 32 32-bit registers, two read ports and one write port. The register file by the three levels of a total of five modules, the lowest level module is the D flip-flop, middle-level module including 32-bit register, address decoder 5, 32 election more than one way strobe, and top-level module is Register File module. Design using behavioral modeling and structural modeling method of combining the first act of modeling methods used to establish low-level modules, then the structural modeling method to build high-level module.

一个电子地图的课程设计,其实还没做完,不过老师要求的功能都差不多实现了,打算在此基础上叠加地貌晕渲的,不过在三角剖分上遇到了些麻烦~,文件夹009中包含了数据的一部分,因为数据大概有十几M就只弄了一部分,还有一个属性数据库.及有些头文件-an electronic map of curriculum design, in fact not done, but teachers required functions are almost the intention on the basis of this superposition Hillshading, but the triangulation encountered a bit of trouble ~, 009 folder contains the data part, because there are about a dozen data M just get the part, there is an attribute database. and some of the first documents

1.ArcEngine组件接口的引用，组件库的初始化，接口授权的使用，创建矢量文件接口的调用步骤

生成tin（不规则三角格网）的算法，根据区域的有限个点集将区域划分为相等的三角面网络-Generation tin (irregular triangular grid) algorithm, according to the region will be a finite number of points equal to the region is divided into triangular surface network

应用背景在物力大地测量学中，重力异常的计算，需要测量计算点的重力值和计算测量点的正常重力。计算正常重力时，需要已知计算点大地坐标，即经度、纬度和大地高，如果采用GPS采集数据，那么获得的大地坐标的参考椭球是WGS84。关键技术此程序，采用WGS84参考椭球参数，因此输入数据为WGS84大地坐标，顺序为，纬度、经度、大地高。输入文件为，Input.dat。输出文件为，output.txt。计算结果为，椭球面以上高程为h处的正常重力。如果将大地高设为0，那么计算结果为此点处参考椭球面上的正常重力。
