beam cross-section meaning in Chinese

梁横断面
射线束截面

For the complication of beam cross - section distortion effect , it becomes sticking out in research and practice that the limitation accompanied by relying merely upon numerical method
在研究和应用中，梁截面畸变效应的复杂性使得单纯采用数值方法进行分析的局限性日益突出。
The general relation between the damage and strain of the beam cross - section is set up and the stress - strain curves of cross - section are made , through the analysis on cross - section balance
通过截面平衡分析,建立了混凝土损伤指标与截面应变关系的一般公式,并得到截面广义力?位移关系曲线。
As an example , polarization changes in vector gsm beams propagating through a telescopic system have been analyzed and illustrated by numerical results . it has been found that propagation - induced polarization changes are non - uniform across the beam cross - section . for the symmetric gaussian spectrum , the effect of the bandwidth on the polarization is barely noticeable
以望远镜系统为例进行的数值分析表明，多色矢量gsm光束的偏振不再是均匀偏振，对源光谱为对称分布高斯型的多色矢量gsm光束，谱宽对光束偏振特性的影响不明显。
