The authr has wosed back caiculation methd ha could calculate the safety fader of slope of sevetal rows root piles 根據反分析的基本原理,提出了反算法計算對于多排樹根樁加固邊坡后邊坡的安全系數。
The results reveal that calculation errors can be reduced with the linear expending nodes , which can be found out by anti - inference method , decided on the limiting equilibration surface based on the advance losm method 結果顯示,用改進一次二階矩法將線性展開點(可用反算法求得)選在極限平衡狀態面上,可減小計算誤差。
2 . to design an axial magnetic field . the cathode lies in 0 . 4 - 0 . 7 of peak value of the magnetic field and excursion channel in a uniform magnetic field to suppress space charge effects ; to design transition section between the gun and excursion channel in converse computation . 3 選擇電子槍陰極處于軸向聚焦磁場峰值的0 . 4 - 0 . 7倍處;漂移通道(互作用區)位于均勻軸向聚焦磁場中,以抑制電子束的空間電荷效應;使用反算法設計電子槍和漂移通道之間的過渡區。
