摘　　要：在HT-7装置上采用红外热像仪测量了活动限制器的表面温度,显示了第一壁温度与等离子体水平位移、波加热参数的关系,一定程度上反映了等离子体与壁相互作用的程度。采用ANSYS计算了活动限制器表面大致的能流分布,其结果与方法可为EAST装置等第一壁温度的测量和能流的计算分析提供一定的参考。The temperature measurement of the mobile limiter by infrared camera was performed on HT-7 tokamak. The high temperature zone of the ion side and electronic side, and the movement of the high temperature zone reflecting the relationship of first wall temperature and horizontal displacement, were observed. According to the relationship of first wall temperature and the limiter position, it is speculated that the plasma boundary is between 268 mm and 266 mm. The results also show the relationship of first wall temperature and wave heating status. The energy flux on the surface of the mobile limiter was obtained by ANSYS analysis. The results and method can provide reference for the temperature measurement and energy flux estimation on the first wall of EAST and other tokamaks.
