摘　　要：观察了在ＨＬ－１装置放电电流上升段、坪区和下降部分由逃逸电子引起的硬Ｘ射线发射模式；硬Ｘ射线发射与破裂、ｍ＝２，３扰动、环电压尖峰、ＩＯＣ放电和超热电子辐射等的关系。给出了３００－３０８ｍｓ间硬Ｘ射线的闪烁脉冲幅度谱，最大能量为６．６ＭｅＶ．Hard X-ray generated at the limiter by runaway electrons has been observed on the HL-1 device during startup, plateau and decline phases of discharge. Emission of the hard X-rayis related to the disruptions, m =2,3 mode activites, instabilities linked to the spikes on loopvoltage, IOC regime discharges and non-thermal radiations.The maximum energy of thehard x-ray is 6. 6 MeV in the interval from 300 to 308ms.
