稳定性的增长 meaning in English

stability augmentation

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。
The strength of convergent shock was enhanced in cylindrical and spherical geometries than in planar geometry . the bubble became more wide and big and the spike became more narrow and long . it showed in spherical implosion that the spike close to the symmetrical axis grew faster than the ring one away from the symmetrical axis
第四，利用lared一s程序模拟柱和球几何内爆过程中rt不稳定性增长，表明收缩几何效应对内爆过程中不稳定性的增长有重要影响，柱和球几何中聚心冲击波的强度大于平面情况，气泡变得更加宽而大，而尖顶变得更加细而长。
