convergence angle 中文意思是什麼

convergence angle 解釋
輻角
  • convergence : n. 1. 聚合，會聚，輻輳，匯合。2. 集合點；【數、物】收斂；【生物學】趨同（現象）。
  • angle : n 【英史】盎格魯人〈cf Angles〉。n 1 角，隅，角落；棱，嬗角。2 【數學】角，角位，角的度數。3 【機...
  1. At any point the convergence is the angle between the meridian as represented on the plane and the n grid line.

    一點上的收斂角是子午線在平面上的投影與N坐標線之間的角度。
  2. Systemic numerical tests are made first, to study the parameter sensitivity of cohesion and friction angle and other elastic parameters to the convergence in tunnel. some comprehensive parameter sensitivity laws have been draw thought these numerical tests. the method of emulating back analysis is illustrated secondly, in detail by tracing the excavation and supporting conditions by the special numerical modeling rested in final program

    主要研究成果： （ 1 ）建立使各個參數靈敏度值具有可比性的靈敏度計算公式，不僅得到了靈敏度分佈規律，而且還得到了各參數對位移的量化影響結果； （ 2 ）詳細闡述了巖土工程模擬反演分析思路與具體方法； （ 3 ）假定圍巖為理想彈塑性模型，在可量測出理論上認為不可測的塑性變形、實現彈塑性位移分離的前提下，提出了彈塑性問題的分步反分析法。
  3. The joint line convergence angle ( jlca ) was measured in degrees as the angle between the distal femoral and proximal tibial articular surfaces for both imaging techniques

    膝關節關節面連線夾角（ jlca ） ：膝關節股骨內外髁關節面與脛骨關節面的夾角。
  4. At any point the convergence is the angle between the meridian as represented on the plane and the n grid line

    一點上的收斂角是子午線在平面上的投影與n坐標線之間的角度。
  5. A blind joint angle and delay estimation method based on trilinear alternating least square technique in uniform circular array ( tals - cjade ) is also presented in section 3, and a blind joint angle and delay estimation method based on complex parallel factor in uniform circular array ( comfac - cjade ) is given to improve the tals - cjade convergence performance

    傳統聯合角度和時延估計方法在過載情況下（用戶數大於陣元數）不能正確估計。與傳統聯合角度和時延估計方法相比， tals - ljade和tals - cjade演算法具有較好doa和時延的聯合估計性能，且在過載情況下仍有較好的性能。
