摘　　要：通过气体放电法研究常温核聚变现象时，用ＮＥ－２１３有机液体闪烁中子谱仪测量了气体放电装置中的中子能谱。验证了气体放电装置中中子的存在。在不同高压下，中子能谱中的峰能量均为２．３８ＭｅＶ。没有能量大于３ＭｅＶ的中子。并与加速器Ｄ—Ｄ中子源的中子能谱进行了比较。中子能谱的测量误差为±６％。In the process of research on cold fusion phenomenon with the gas discharge method, the NE-213 orsanic liquid scintillation neutron spectrometer was used to measure neutron energy spectra from the sas discharge facility. It was found that neutrons were emitted from the gas discharge facility. The Peak energy in neutron spectra is about 2. 38MeV. Neutrons whose energy is larger than 3 MeV haven' t been found. The neutron spectra from the gas discharge facility and D-D neutron source are compared. The experimental error of neutron spectra is about ±6%.
