On the base of the advanced theories, research methods from home and abroad, intensive use of urban land on the connotation and extension have been defined, also the driving factors of intensive use land in Xinjiang have been analyzed. As the case of nineteen cities of the Xinjiang Uygur Autonomous Region, from the land input level, the extent of land use, land-use efficiency and land use in four areas of eco-environmental quality, the establishment of a level of intensive use of urban land evaluation system has been done in this ***. Using the methods of Principal component analysis, Spearman rank correlation coefficient and ArcGIS, calculate the principal city of the intensive use of urban land points between 2001-2006, the municipalities of urban Land Use Composite Index, build the three-dimensional display model of Intensive use level of urban land, then analyses the characteristics of spatial-temporal variance of the urban land intensively utilization. Finally, analysis propose measures and advices.

Firstly, based on the Duhamel integral and dynamic reciprocity theorem, the generalized Duhamel integral expression is written to a point in the half infinity space under moving load. Secondly, the train load is considered as a series of centralized loads with fixed distance. The dynamic response expression of a point in frequency domain and frequencywavenumber domain are derived out through the Floquet transform and Fourier transform under a moving load, and then the dynamic response of a point is gotten ...

以Duhamel积分为基础，首先应用动力互等定理，得到了移动荷载作用下，半无限大弹性连续介质空间上任意点的动力响应的广义Duhamel积分表达式；然后将列车荷载简化考虑为一系列具有一定间距的集中荷载，采用Floquet变换、Fourier变换等方法，得到了一个集中移动荷载作用下任意拾振点ξ的动力响应在频域和频率波数域内的表达式，进而由叠加原理得到列车荷载作用下的动力响应解；最后，通过算例说明该算法的适用性。

By means of a resonable and approximate treatment the dependent variables of the integral equation are reduced to depend only on the two coordinates of the wing plane.

通过合理的近似处理，使积分方程的自变量仅依赖于机翼所在平面的两个座标，这就使我们在利用有限无法进行数值解时，只需在机翼平面上划分元素，避免了在流场空间中划分元素的传统作法，从而大大降低了对计算容量的要求和计算工作量，使跨音速三维机翼的气动力计算有可能在较小的计算机(例如709机)上完成。

根据所建立的评价方法对试验地土壤碱解氮、速效磷、速效钾、全氮、全磷、全钾、有机质含量和pH值的空间变异性进行评价。

In this paper, we have deduced an iterative algorithm with relaxation parameter from the successive over relaxation method, which not only deduce the necessary of computation time and memory space but also is propitious to overcome the sensitivity of reconstructed images to incomplete noisy data.

从解大型线性方程组出发，由逐次超松弛法(Successive Over Relaxation， SOR)推导出一种带有松弛因子的迭代法。与 SOR 法相比，该算法不仅大大降低了对计算时间和内存空间的需要，而且有利于克服重建图像对不完全噪声数据的敏感性。

Unlike the usual residual analysis, The residuals are treated as a sample of a random variable, which specifically is a white gaussian noise in this paper.

在空间技术的实际资料处理中，经常遇到不同待估参数组合解算的RMS水平大致相当而估值结果相差甚远的情况。

The chapter first studies the closedness, semicontinuity and cone semicontinuity of cone efficient point sets and cone weakly efficient point sets of the perturbed objective sets when both the objective maps and constraint maps are continuous and the constraint cone is semicontinuous.

进而还证明了当扰动变量形成Baire空间时，大多数（在Baire分类意义下）约束集或序受扰动的联合锥弱有效解集在连续意义下是稳定的。

Experiment and flow visualization are conducted in a water-filled cavity which cover the range of Ra=1×10〓----6×10〓 and Pr=3. 3---6. 5. Similarity theorem is applied in analytical investigations. And core region stratification effects to heat transfer are studied. By using scale analysis, temperature and velocity profiles in turbulent natural convection boundary layer are obtained. The results reveals that for turbulent natural convection in enclosures, the bulk of the cavity fluid is essentially statement with thermally stratified temperature and the only substantial motion is that in the boundary layer along four side walls.
