5) first-order approximation method
一次近似
1.
Based on the first-order approximation method(FAM),a non-Cartesian variables and a Cartesian variable s and a Cartesian u_2,which denote the arc-length stretch and the transverse displacement respectively,are employed to describe the deformation of the beam.
基于一次近似理论,采用弧坐标分量和Cartesian坐标分量共同描述柔性梁的变形场,并采用Green应变张量描述应变能,用Hamilton原理建立系统动力学方程,揭示产生动力刚化现象的力学本质。
补充资料：多次库仑散射
多次接续发生的库仑散射为多次库仑散射。多次库仑散射后带电粒子的净偏转角近似地正比于该粒子的电荷，反比于其动量p与速度v的乘积pv。在核乳胶及重液泡室中，常用此性质测定带电粒子的pv值。
