类太阳活动星的X射线观测与研究进展

扼要介绍了类太阳恒星星晚射线辐射的研究历史，综述了Ｘ射线辐射与恒星参量的关系，并对星冕的加热机制作了介绍。类太阳恒星的Ｘ射线辐射与表面磁场有关，因此测定晚型星表面的磁场很重要。

Progress in the X-ray Observation and Study of Solar Like Stars

The History of researches on the X-ray emission of solar like stars is introduced briefly in this article. With the continuous progress on observational techniques, it has been revealed thatthe magnetic field plays very important role in X-ray emission of late-type stars. Here we discuss: the coronae model where the X-ray is emitted; the dependence of the X-ray emission on the stellar parameters, such as, the rotation or Rossiby number, age, spectral type, and the chromosphere activity; the X-ray flare; the long X-ray time variability; the coronal heating mechanisms. Finally, some of research notes for future are briefly discussed.
