The authr has wosed back caiculation methd ha could calculate the safety fader of slope of sevetal rows root piles 根据反分析的基本原理,提出了反算法计算对于多排树根桩加固边坡后边坡的安全系数。
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 结果显示,用改进一次二阶矩法将线性展开点(可用反算法求得)选在极限平衡状态面上,可减小计算误差。
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 选择电子枪阴极处于轴向聚焦磁场峰值的0 . 4 - 0 . 7倍处;漂移通道(互作用区)位于均匀轴向聚焦磁场中,以抑制电子束的空间电荷效应;使用反算法设计电子枪和漂移通道之间的过渡区。
