The goal of the exercise is to show the effect on the shear force and bending moment distribution of " smoothing " out the distribution of a load acting at a point on the beam 这个练习的目标是显示作用于梁上的点集中作用力的分布其对剪力及挠曲弯矩分布的平滑化的效果。
But the effects on the beam are strong when the undulator is located in the 4th straight section , and the storage ring will not work if the compensation methods are not implemented in the ring 但安装在第四直线节时，在高亮度运行模式下对电子束流的影响较大，如不进行补偿，环将无法正常运行。
During these processes , diffraction , self - phase modulation , cross - phase modulation and physical distance between the beam centers all have important effects on the beams and the pulse beams propagation 在这些过程中，衍射、自相位调制、交叉相位调制、光束之间的间距等都对光束和脉冲光束在非线性介质中的传输产生重要的影响。
Again , this is an important experience to pay attention to , because being on the beam , moving toward home , does not render you incapable of experiencing the infinitude of life in the act of being 容我重申一次，你目前的经验非常重要，你必须专注其上，因为，保持在光明指引下、往天乡迈进之际，你并不会经验不到那无限生命在有限世间的活动的。
Vibration test was done on the beams under different state . main bars of all the specimens were taken out for static tensile experiment after fatigue experiments . it showed that the vibration test cannot predict the fatigue failure of the fatigued beams effectively 疲劳试验中,对梁在不同疲劳状态下的振动特征进行了测试;在疲劳试验结束后,取出梁中主筋进行静力拉伸试验。
Chapter 2 : the beam propagation of x - ray in an inhomogeneous plasma with a continuous varied refractive index is studied . we emphasize , theoretically and numerically , on the analysis of the effect of refractive index gradient on the beam parameters 第二章：研究了x射线激光光束在折射率连续变化的非均匀等离子体介质中的传播，从理论和数值模拟上着重讨论了折射率梯度效应对光束参数的影响。
Many theoretical analysis and numerical simulations on many kinds of the factors that will do more effect on the beams with the help of the mature electronic trajectory program - - - - - egun , a set of formula and some program that were my code have been done 首先对计算电子轨迹的数值模拟程序egun的工作原理[ 35 ]及程序的应用进行了详细的分析和了解,对电子光学系统的基本理论与计算方法进行了详细的阐述。
