1) stepped variable thickness
阶梯式变厚度
1.
A differentinal equation of transverse free vibration is established for circular plates with stepped variable thickness,and the initial parameter solution of this equation is obtained.
建立了阶梯式变厚度圆板横向自由振动的微分方程 ,得出其初参数解。
2) stepped thick plates
阶梯式变厚度板
3) gradient of thickness variation
变厚梯度
1.
Furthermore,thickness,gradient of thickness variation and curvature radius have strong correlation to delamination and void,and abrupt thickness zone also results in rich resin appearance easily.
结果表明,复合材料构件厚度过薄(<1mm)或过厚(>5mm)、变厚梯度突变以及曲率半径过小(<2mm)将增大缺陷产生的比例;厚度变化、变厚梯度和曲率半径变化均会产生分层和孔隙,变厚梯度区最易产生富脂。
4) diversification of rank
阶梯式变化
1.
It is acquired that the destroy of the slope appears and expands along the weak structure surface near sliding surface,the sinking curve of rock bedded slope with groups of weak structure surface presents the diversification of rank,as is actively significance for learning the distortion of whole slope through detecting displacement change of rock slope in secure sites.
结果表明,边坡的破坏主要是沿滑动面附近的软弱结构面萌生并扩展,含多组软弱结构面的顺层岩质边坡下沉曲线具有呈阶梯式变化的特征。
5) Staircase transition
阶梯式跃变
6) rounded stepwise gradient
圆阶式梯度
补充资料：反射式阶梯光栅(reflection stepped grating)
分子式：
CAS号：
性质：又称反射式阶梯光栅(reflection stepped grating)。其性质介于小阶梯光栅和阶梯光栅之间。它与闪耀光栅不同，不以增加光栅刻线，而以增大闪耀角(高光谱级次和加大光栅刻划面积)来获得高分辨本领和高色散率。例如当8～80条/mm刻线，60°～70°闪耀角，40～200级高光谱级次时，分辨本领大于106。普通闪耀光栅为105。但它每一级光谱区很窄，只有1～10nm。可用交叉色散法将这些上百级次的光谱分开。
