简介：重点研究了不同预热对烧蚀RT弱非线性模耦合的影响。首先不同预热情况烧蚀RT不稳定性的线性增长率曲线明显不同。不同预热情况的模拟结果都表明：烧蚀RT的模耦合系数是k／kc的函数，二次和三次谐波的产生系数C（k）和D（k）遵从定标关系C（k）：c1（1-c2k/kc），D（k）=d1-d2k/kc＋d3（k/kc）^2。弱预热和中等预热情况，二次谐波的产生系数约只有经典RT的50％，三次谐波的产生系数约只有经典RT的20％。两体模耦合起主要作用，n次高次谐波可近似看作是由（”一1）次两体模耦合产生的。由于烧蚀RT不稳定性两体模耦合系数小于1，所以高次谐波的产生系数很快衰减。由于非线性作用变弱，单模扰动的非线性饱和阈值明显增大，意味着基模有较长时间的线性增长，另外，向长波长方向的模耦合系数明显大于经典尺丁不稳定性数值，因此，烧蚀RT非线性模耦合容易形成长的尖顶，从而对点火构成严重威胁。
