But the introduction of new basis functions also poses a new problem, that is, the complexity of computation of two matrixes' elements in the derivative generalized eigenvalue problem in NMM. Fortunately we found a recursive algorithm and solved it concisely.

在引入幅度基函数和斜度基函数后，广义特征值问题中矩阵元素的计算变的繁琐，我们运用一种递推算法简洁地解决了这个问题。

For reducing boundary distortion area, the elevations of grid DEM are viewed as a discrete sequence under a generalized coordinate, so that the boundary problem of two-dimensional discrete wavelet transform is turned into the boundary problem of one-dimensional discrete wavelet transform, which not only greatly reduces the boundary distortion area, improves the precision of reconstructed DEM data near the boundary, but also decreases the number of zeros adding on the boundary for wavelet transform, and boosts the compression ratio. On the basis of analyzing the distribution characteristics of coefficients in low and high frequency bands, a mixed entropy coding plan is applied, and a high efficient quantizator called"self-adaptive hard threshold"is established, which is helpful for improving the precision of the reconstructed DEM data and for enhancing compression ratio.

为了减小小波变换山区格网DEM数据压缩中边界失真区域，将山区格网DEM高程值视为广义坐标下的离散随机序列，把二维离散小波变换中的边界问题转换为一维离散小波变换中的边界问题，不仅大大减少了小波变换边界失真区域，提高了重构DEM数据边界点的精度，而且减少了边界补零个数，提高了压缩比；通过对山区格网DEM数据小波变换低频区和高频区变换系数分布特点的分析，采取了霍夫曼—游程混合熵编码方案，设计了高效、低失真的"自适应硬阈值"量化器，即对低频区变换系数不进行量化，直接进行霍夫曼编码；对高频区变换系数则先用"自适应硬阈值"方法量化处理，再进行游程编码。

Promoting the successful construction of GIP is very important to rapid economic development, people's livelihood improvement and social harmony. The problem of project has been focused in the research field of project management theory for decades. Many scholars have carried on a large amount of research on the successful standards of the project and the key factors that affect the project's success. However, the research on the problem of GIP success in our country still remains very weak, it is necessary for us to explore and advance the research achievements of GIP for the reason of cultural gap and characteristics of GIP itself.

项目成功因素的研究是近几十年项目管理理论研究的一个重点，国外许多学者围绕项目成功标准和影响项目成功的关键因素进行了大量的研究，但由于文化环境差异和政府投资项目特点等方面原因需要我们对项目管理理论中已有的项目成功因素研究成果在我国进行新的探索和创新，可是我国学者对政府投资项目成功因素的研究仍然十分薄弱，因此，研究我国政府投资项目成功因素还具有重大理论意义。

The mechanism of the impact of satellite-city on urbanization is industrialization and the third industry development and so on. Finally, with careful analysis on the problem in the development of satellite-cities, The article expound the question existing of satellite city : the disparity in urban and rural areas is great, the great difference between satellite-city and central district, the problem of the peasantry who lost glebe and so on. The article defined the function of each satellite-city and put forward policy advice.
