  1. The results obtained from the simulation example suggest a good effect and significance of using gps simulation data for demonstrating the feasibility and validity of an od design or an algorithm of certain problem. 4 the ill - conditioned problem existing in relative kinematic od using gps carrier - phase data is discussed and then some preliminary efficient approaches for solving this problem are given out there are several reasons that cause the ill - condition pro

    （四）探討了星載gps相位相對定軌中的病態性問題，並嘗試給出了較有效的解決方案地面基準站、低軌衛星和gps衛星之間的幾何形狀分佈不佳，差分技術的應用使得模糊度之間及模糊度和三維坐標向量改正之間產生較強的相關性，往往都會導致星載gps定軌中的法矩陣的病態性。
  2. The classic difference scheme of euler is employed to solve the forward problem, and the truncated singular value decomposition is used to solve the ill - conditioned system of algebraic equation

    用古典歐拉差分格式求解正問題，用截斷奇異值分解法求解病態方程組。
  3. The system identification method is presented for backcalculating the dielectric property and thickness of pavement structures. the method of singular value decomposition is put forward to diagnose the ill - conditioned governing equation and the problem of finding solution to ill - conditioned governing equation is successfully resolved. the parameter adjustment arithmetic with high accuracy, which is based on precise theory and can be converged rapidly, is established

    提出了路面結構層介電特性及其厚度反演分析的系統識別方法，將奇異值分解技術應用於控制方程的病態診斷和求解，有效地解決了控制方程病態時的求解問題，建立了理論嚴謹、收斂快、精度高的模型參數調整演算法，並開發了路面結構層材料介電特性及其厚度反演分析軟體sidthk 。
  4. Based on interval the computation cost of interval newton algorithm is larger than the general newton iteration method. the computation time of interval newton algorithm tends to grow exponentially with the dimension. even for small problems, interval newton algorithm often requires enormous computation time if the nonlinearity of the problem is very large or the problem is ill - conditioned

    但是由於區間牛頓法是以區間為迭代單位，其計算量遠大於一般的牛頓類迭代法，其計算時間隨著方程組維數n的增加而呈指數增長；而且即使在維數n很小時，若方程組的非線性程度很強或方程組為病態，所需的計算時間也很大。
