  1. Second part - the main contribution and research results of this paper are focused on as follows : ( 1 ) how to use the measurements of a dual frequency gps receiver to determine the ionospheric delay correction model for single frequency gps of a local range ; ( 2 ) how to separate the instrumental biases with the ionospheric delays in gps observation ; ( 3 ) how to establish a large range grid ionosphere model and use the gps data of chinese crust movement observation network to investigate the change law of ionospheric tec of china area ; ( 4 ) how to improve the effectiveness of correcting ionospheric delays for waas ' s users under adverse conditions. ( 5 ) how to establish the basic theory and the corresponding framework of monitoring the stochastic ionospheric disturbance using gps ( 6 ) how to improve the modelling ability of ionospheric delay according to its diurnal, seasonal, annual variations based on gps ; ( 7 ) how to meet the demand of correcting the ionospheric delay of high - precision orbit determination for low - earth satellite using a single frequency gps receiver 1 extracting ( local ) ionospheric information from gps data with high - precision the factors are systematically described and analyzed which limit the precision of using gps data to extract ionospheric delays

    二、具體研究工作的系統報告，主要集中在以下幾方面：研究如何利用單臺雙頻gps接收機的觀測信息確定電離層延遲改正模型，為小范圍的單頻用戶服務；研究如何實時分離gps觀測中的儀器偏差與電離層延遲；研究如何建立較大區域的電離層格網模型，進而初步設想利用中國地殼運動觀測網路深入研究我國領域的電離層的電子濃度變化規律；研究單頻用戶在不利條件下，如何更好地利用電離層延遲改正信息；研究利用gps監測隨機電離層擾動的基本理論和框架方案；研究如何綜合顧及電離層的周日、季節和年變化，進一步提高利用gps模擬電離層延遲的能力；研究如何實現星載單頻gps低軌衛星的精密測軌中的電離層延遲改正要求。
  2. With observation on the resistance of zwm - type grid - shaped walking hydraulic support on no. 7177 working face of kongzhuang coal mine, the load - carrying properties are analysised, measures for raising usage rate of the support working resistance have been put forward

    通過觀測孔莊礦井7177工作面zwm網格式液壓邁步放頂煤支架的阻力，分析了支架承載特性，提出了提高支架工作阻力利用率措施。
  3. Therefore, more challenges have arisen for query optimization in database grid than traditional distributed database. following this observation, the design of a query optimizer in dartgrid ii is presented, and a heuristic, dynamic and parallel query optimization approach to processing query in database grid is proposed. a set of semantic tools supporting relational database integration and semantic - based information browsing has also been implemented to realize the above vision

    克服數據庫網格特性所帶來的困難需要為數據庫網格提供全局一致的數據表達模式各結點數據模式到全局模式之間的映射方法各結點之間負載平衡和結點動態加入和退出系統的控制策略數據庫網格查詢優化器結構設計以及一整套適合數據庫網格的查詢優化演算法。
  4. To build the appearance model of mouse target in video sequences, this paper studied a general method to retrieve image observation under the bayesian framework. first, the image is partitioned into numerous grids, and the image observation is assumed as independent between different grids. then the image observation of a whole image can be configured based on the configuration of image observation in each grid

    為建立視頻圖像中鼠類目標的表觀模型，本文研究了在貝葉斯框架下提取圖像觀察的一般方法，通過將圖像網格化，並認為各網格間的圖像觀察是相互獨立的，從而可以在求解各個網格圖像觀察的基礎上求解整幅圖像的表觀模型。
