cylindrical geometry meaning in English
圆柱几何体
Examples
- Firstly , two - dimensional rt instability in cylindrical geometry was simulated by the lared - s code and the results agreed well with the linear theory of rt instability in cylindrical geometry
首先，利用lared - s程序模拟二维柱几何中rt不稳定性的增长，计算结果与线性理论符合得很好，检验了程序的可靠性。 - Thirdly , multimode - coupling phenomena in cylindrical geometry was analyzed by the simulation . the growth of every mode and its harmonic was qualitatively compared well with the solutions of mode - coupling equation . fourthly , the rt instability in cylindrical and spherical geometries was calculated during an implosion
第三，利用lared一s程序模拟柱几何中rt不稳定性的多模祸合问题，对各个模及其高次谐波的变化进行了分析，并且与模藕合方程的解定性地进行比较，结果符合得较好。 - At linear stage , the theoretical growth rate for the rt instability in cylindrical and spherical geometries was enhanced ( or reduced ) due to the decrease ( or increase ) in the perturbation wavelength during an implosion ( or explosion ) . even in the absence of an acceleration the perturbation could grow in the convergent geometries . the amplitude growth rate was proportional to the cube of the convergent ratio in spherical geometry and to the square of the convergent ratio in cylindrical geometry
在线性阶段，已有的研究表明：一方面，在内爆(或外爆)过程中扰动波长变短(或变长) ，使得不稳定性的增长率变大(或变小) ；另一方面，即使不存在界面加速度，界面运动仍然可能导致扰动幅度的增加，柱几何中扰动幅度的变化速率正比于界面收缩比的平方，球几何中扰动幅度的变化速率正比于界面收缩比的三次方，并且扰动幅度的变化方式(增加或减少)只与初始时刻扰动幅度的增长速率(正或负)有关，而与界面的运动方向(向内或向外)无关。
