小尺度无序磁场普遍存在于高能天体的爆发过程中。在明确了小尺度的物理条件后，详细描述了近年来国际高能天体物理研究领域中和小尺度无序磁场相关的湍流、激波、等离子体不稳定性和磁重联等前沿问题，并相应介绍与小尺度无序磁场相关的粒子加速和辐射过程的最新进展。介绍的内容主要是基于流体或磁流体计算机数值实验得到的结果，对部分计算程序也做了简单介绍。最后，提出在这一领域开展研究工作的一些建议。

Random and small-scale magnetic elds are popular in the explosion of high-energy celestial objects. We clearly state the physical condition for applying the relevant physics. The important issues, such as kinetic turbulence, collisionless shock waves, plasma instabilities, and collisionless magnetic reconnection, are described in detail. In this paper,we also mention the particle acceleration and non-thermal radiation. These physical issues are consistent each other within a general framework. Some numerical simulation codes are simply introduced. Finally, we present some suggestions for carrying out these projects in Chinese high-energy astrophysical eld.
