病態問題
  • ill : adj （worse; worst ）1 〈用作表語〉有病的。 ★英國此義作修飾語時是用 sick 美國無論作表語或作修飾語...
  • conditioning : n. 1. （商品的）檢驗。2. （空氣、濕度等）調節。3. 【冶金】整修。4. 【心理學】條件作用。
  • problem : n. 1. 問題，課題；疑難問題；令人困惑的情況。2. 【數、物】習題；作圖題。3. （象棋的）布局問題。adj. 1. 成問題的；難處理的。2. 關于社會問題的。
  1. 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

    病態性在常規大地測量網平差、 gps快速定位、大地測量反演以及變形監測網的數據處理中是大量存在的，其危害性十分嚴重。
  2. 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數據處理、工程式控制制網平差、形變觀測分析、大地測量反演等測量數據處理領域，系統的病態性問題是常見的，並且病態性的危害作用非常嚴重。
  3. In this thesis, the origin, definition, and dependence of the solution - uniqueness of the inverse problem and ill - conditioning are discussed first

    因此，本文首先從反問題的起源和定義入手，然後著重分析研究了反問題解答的適定性問題。
  4. In order to get this, some useful explorations on how to analysis and solve the problem of the ill - conditioning have been made and several biased estimators have been put forward. in fact, analyzing the essence, overcoming the effect of ill - conditioning and obtaining more accurate and stable parameters estimator is an new task in gps surveying data processing, which have been determined as an important studying field in contemporary surveying error theory and engineering data processing by the international association of geodesy ( iag )

    事實上，分析測量平差系統病態性的實質、克服或減弱測量平差系統病態性的影響、採用有偏估計等方法提高參數估計和平差成果的精度，是當前gps等重大測量工程數據處理中所面臨的一個重要課題，它已被國際大地測量協會（ iag ）確立為現代測量誤差理論及數據處理研究中的一項重要內容。
  5. Based on the singular - value decomposition method, several schemes to readjust the singular value of design matrix are proponed through perturbation analysis, and a simulated example is studied for illustrating these schemes can overcome the ill effect when there exist ill conditioning among the columns of the design matrix. the problem of selecting the biased parameter is studied in every scheme

    通過對觀測方程進行擾動分析，基二奇異值分解技術，提出了若干種修正奇異值的方案，討論了奇異值修正方案中偏參數的選取問題，並且結合模擬算例對這些方案在克服設計陣的病態性影響方面的作用進行了研究。
