In HL-2A, magnetohydrodynamics instabilities are investigated by means of the Mirnov probes.

在HL-2A上用Mirnov探针探测磁扰动是研究等离子体不稳定性的重要方法之一。

In summary, the drive current by Alfvén waves can be enhanced by plasma rotation The negative magnetic shear is favorable for the efficiency of the current drive by Alfvén waves Moreover, in the reversed shear configuration the current drive due to Alfvén waves in an rotation plasma can obviously change the plasma current profile The Alfvén wave current drive may be useful in controlling the current profile in order to suppress magnetohydrodynamic instabilities.

另外，我们还发现负剪切区域愈大，同时安全因子极小值q〓愈小，对阿尔芬波电流驱动愈好。总之，等离子体极向旋转能够增强阿尔芬波电流驱动，负磁剪切对阿尔芬波电流驱动是有利的。另外，反磁剪切位形下旋转等离子体的阿尔芬波电流驱动可以明显改善等离子体电流剖面。

Three different numerical iterative algorithms are developed and the accuracy and stabilities of them are compared. Tension and compression instabilities are studied and effects of Conservative Smoothing Approach and artificial viscosity on stabilities are discussed. Based on Taylor series expansion, Modified SPH method is proposed. The discrete forms of the function and its first derivative estimations of the kernel function are deduced in both one and two dimensional space.

讨论了三种不同的数值迭代算法对计算精度和稳定性的影响；分析了不稳定性产生的根源，包括拉伸不稳定和压缩不稳定，探讨了保守光滑算法和人为粘性对稳定性的影响；在Taylor展开的基础上提出了一种修正的SPH方法，并推导一维和二维情形下函数的核估计和函数的一阶导数核估计的离散形式，结果表明，二维情形下MSPH方法可以很好的改善边界粒子的计算精度。

A periscope probe is used to map the combustion space and eliminate hot spots and instabilities.

一种潜望镜探针是用来测绘燃烧空间，并消除热点问题和不稳定性。

These problematical instabilities leading to many new difficulties which render the previous thinking as confused as we were when we started this discussion.

这些问题的不稳定导致许多新的困难，以致思维混乱是由于我们以前当我们开始这项讨论。

Avoid using input elements that are tangent to each other since this may result in geometric instabilities in the tangency zone.
