  1. 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

    在線性階段，已有的研究表明：一方面，在內爆（或外爆）過程中擾動波長變短（或變長） ，使得不穩定性的增長率變大（或變小） ；另一方面，即使不存在界面加速度，界面運動仍然可能導致擾動幅度的增加，柱幾何中擾動幅度的變化速率正比于界面收縮比的平方，球幾何中擾動幅度的變化速率正比于界面收縮比的三次方，並且擾動幅度的變化方式（增加或減少）只與初始時刻擾動幅度的增長速率（正或負）有關，而與界面的運動方向（向內或向外）無關。
