The curve continual steel box Liang shearing force stagnates the effect finite element analysis box section Liang has the big flexural rigidity and torsional stiffness, the stress performance good, spanning ability big, on the bridge the field of vision open and so on the merits, is in the bridge design the commonly used structural style, when receives under the dead load or the symmetrical live load function winding, because the lifting surface detrusion causes its bending stress to present the non-uniform distribution condition along the Liang width direction, this phenomenon is called "the shearing force to stagnate the effect".

曲线连续钢箱梁剪力滞效应的有限元分析箱形截面梁具有较大的抗弯刚度和抗扭刚度、受力性能好、跨越能力大、桥上视野开阔等优点，是桥梁设计中常用的结构形式，在受恒载或对称活荷载作用下挠曲时，由于翼板的剪切变形致使其弯曲应力沿梁宽度方向呈现不均匀分布状态，此现象称为&剪力滞效应&。

The results show that,(1) the ion acceleration and energization mainly occur in the middle of dipolarization at distance of -12 RE to -8 RE,(2) the ion acceleration and energization along the direction perpendicular to magnetic field are faster than along parallel directi on,(3) variations of speed and energy for lighter ion are faster than that o f heavier ion,(4) the higher the initial energyis,the faster the ion accelerati on is, and the more energy is obtained by the ions.

主要结果为：(1)离子的加速及能量变化主要发生在磁场偶极化过程的中期，对应的地心距离位于-12RE到-8RE之间；(2)垂直于磁场方向上离子加速及能量变化较快，平行方向上较慢；(3)轻离子较重离子加速及能量变化快，磁场偶极化终结，3种离子的能量均可增加200倍左右；(4)初始能量较高时，离子加速及能量变化较快，离子最终获得的能量较大。
