我必须告诉你多少次（你才能记住）？！（世界上）根本没有“朗道阻尼”这码事！

How many times do I have to tell you ?! There is no such a thing called " Landau Damping "!

在机器研究过程中观察到束流集体不稳定性可以被八极磁场产生的朗道阻尼很好地抑制。

It was observed in machine study that , Landau damping caused by the octupole field can suppress the beam collective instabilities .

快电子的有效温度较好地满足共振吸收的温度定标律是由于反射激光加速与共振吸收机制均是通过朗道阻尼或波破对电子进行加速的。

The effective temperature of fast electrons is consistent with the temperature scaling of the resonance absorption , which is due to Landau damping or wave breaking .

对于对偶等离子体中的声波，我们发现它是一个无朗道阻尼的波，声波的阻尼全部来自粒子间的库仑碰撞。

For a pair plasma , it is found that the sound wave does not suffer any Landau damping and its dissipation is only due to the Coulomb collisions .

结果表明：碰撞粘滞对波包的阻尼作用不容忽视，而非线性朗道（Landau）阻尼对波包的阻尼作用较弱。

The results show the effect of collision damping can not be neglected , whereas the nonlinear Landau damping is a weak effect compared with the collision one .
