摘　　要：本文给出一种氚钛厚靶氘氚反应加速器中子源的中子产额、能谱和角分布的计算方法,并开发了相应的计算模拟程序。用自行开发的计算程序计算了入射氘束流能量低于1.0 MeV时加速器中子源的中子产额、能谱和角分布,给出了氚钛厚靶的一些典型计算结果,并对结果的可靠性进行分析。A mathematical method and a computer program were developed to calculate the yield, energy spectrum and angular distribution of neutrons from the T（d, n）^4 He reaction in a thick tritium-titanium （TiTx） target for incident deuteron beam energies lower than 1.0 MeV. Some calculated results using this method are presented, including integrated neutron yields, neutron energy spectra and angular distributions. The reliability of the results was analyzed.
