摘要
介绍了耀斑各波区（从EUV到红外）氦线观测的进展，从中阐明氦线观测和研究在提供太阳耀斑物理参数，了解耀斑动力学过程、电场、能量平衡及高能粒子产生和传输方面的特殊意义，并分析了这个领域目前已经取得的研究结果和今后研究中在观测技术和理论分析两个方面尚需解决的关键问题。
In this paper a brief survey about the recent results of the solar flares in the helium lines is given, including the new observations from EUV to infrared and their interpretation. It is shown that the helium lines can offer valuable diagnositic information about solar flares, such as the thermodynamic parameters, mass motion, electric fields, the dynamic characteristics of the accelerated ion beams and the energy balance of the flares. Also discussed are the key problems to be solvd both in observation and theory.
