This paper can infer time of GPS satellite clock that there is a periodic variation of 12 sidereal hour, and GPS satellite orbit period is just 12 sidereal hour, no doubt, it be designed for to check up time.

本理论可以推导出GPS卫星钟的快慢，有12恒星时的周期变化，而GPS卫星轨道周期正好为12恒星时，极可能是为了方便校对时间而设计的。

Expanding the modification model in vector spherical harmonics, we obtained the absorption and scattering coefficients of the beam wave case.

将所得的修正解按矢量球面波函数展开，就球形粒子对束状波的消光系数进行推演和计算，并与平面波Mei理论和国外的实验结果进行比较，验证了修正解的正确性。

Extended Kalman filter is based on first-order Taylor expansion,for which reason,it introduces too much error.

In our male-dominant male-centric tradition, we blame the Asian woman for the phenomenon. And in our minorities-are-the-victims tradition, we also blame White Privilege, White sexual imperialism, and the white-washing of the world that globalization has wrought–theories we use like a panacea to explain why any minority race may experience inequality in this world.

按照男性中心的社会传统，我们把责任推到亚裔女性头上；按照"少数族裔是受害者"的社会传统，我们指责白人特权主义，指责白人性爱帝国主义，指责全球化造成的白人给全世界人民洗脑的现象——我们用这些理论来解释一切少数族裔所遇到的不平等，好似包治百病的万金油。

This research hope uses the information of "bond yield spread" and "the market value of equity" which is available in the market to do the calibration by "Nelder-Mead Simplex Method" numerical method, and obtain the theoretical default probabilities which calculates in the most suitable property market value and the volatility of property market value.

由於资产市值与资产市值波动度的难以评估，所以无法以正向带入变数预测公司违约机率，本研究主要希望利用市场上所能获得的资讯『公司债殖利率差』、『股东权益市值』对模型以Nelder-Mead Simplex Method的数值方法做回推求得在最适资产市值与资产市值波动组合下计算出的理论违约机率。

Based on the analysis to the particularity of the cruise missile attacking, a complete recognition method based on the knowledge is developed. A new fractal-based infrared image feature extraction method is presented and the detailed theoretic analysis and implement procedure of this algorithm is submitted and tested in some experiments. With the limitation of the line detection based on traditional Hough transform that the information of the length and the end points of the line is unavailable, a new algorithm which makes use of the accessional strategy based on precognition information is put forward to meet the demand for more information of the line, simulation results show this method is effective. Finally, the whole process of airport target recognition is presented and the result images are also given.

使用分形方法提取目标的特征，在知识指导下，提出了一种基于目标特征模型的降维的形态学分形维数计算方法，对传统分形方法进行了改进，从理论上推证了算法的合理性，并对算法进行了仿真分析；针对传统Hough变换无法获得线段端点和长度信息的局限性，提出了一种基于目标特征先验知识的Hough变换融合策略，通过引入目标先验知识，可以有效地获得直线信息；对信息多而复杂的机场目标采用基于知识的目标识别方法，使用置信度模型实现不确定推理，对目标进行识别判断，将知识贯穿于整个识别过程中，对目标进行了有效地识别。

This condition is weaker than the conditon for complete topological conjugacy of two families of systems, so it is significant and useful for deducing from relatively simple systems or systems with known bifurcation points to the systems with unknown bifurcation points.

这一条件比两族系统完全拓扑共轭弱，因此是有理论意义的，可以使我们从相对较简单的或已知分支点状况的系统来推知未知系统的分支点。

Aiming at the obtain method in the whole life cycle of the automobile, we use the conception of knowledge base and knowledge management, adding describing information for the stored information, make the system enable to identify and deduce the new information, and provide the guidance and constrainment based on the workflow.

第五章结合了理论研究开发设计了基于以PDM与ERP系统集成为代表的实现多视图转换的映射系统，以及针对实现集成后对信息进行知识表示、推理、搜索及推送的知识管理系统。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.

万寿菊对土壤要求不严，以肥沃。排水良好的砂质壤土为好。

He unstepped the mast and furled the sail and tied it.
