ill-conditioning problem中文什么意思
例句与用法
- As we know , the ill - conditioning problem is present in data processing of geodesy networks adjustment , gps ( global positioning system ) fast orientation , geodesy inversion and distortional inspecting networks . moreover , its damage is serious
病态性在常规大地测量网平差、 gps快速定位、大地测量反演以及变形监测网的数据处理中是大量存在的，其危害性十分严重。 - Generally , the ill - conditioning problem not only exists in global positioning system ( gps ) data processing , surveying adjustment , observation deformation analysis and geodesy inversion , etc , but also its ill effects are very serious
在gps数据处理、工程控制网平差、形变观测分析、大地测量反演等测量数据处理领域，系统的病态性问题是常见的，并且病态性的危害作用非常严重。 - But when sampling rate is high , most traditional digital signal processing and control algorithms are inherently ill - conditioned . considerable progress has been made by the use of delta operator on ameliorating ill - conditioning problems
研究结果表明，当采样频率很高时，传统的信号处理和控制方法存在着不可避免的缺陷，而采用delta算子描述代替移位算子描述方法可以适当地改善这些缺陷。 - 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)探讨了星载gps相位相对定轨中的病态性问题，并尝试给出了较有效的解决方案地面基准站、低轨卫星和gps卫星之间的几何形状分布不佳，差分技术的应用使得模糊度之间及模糊度和三维坐标向量改正之间产生较强的相关性，往往都会导致星载gps定轨中的法矩阵的病态性。
