摘　　要：致密热解碳层是高温气冷堆包覆燃料颗粒必要的组份，本文介绍了致密热解碳层的功能和要求，研究了热解沉积温度对热解碳密度，沉积效率和沉积速率的影响。制备密度为１．９０±０．１０ｇ／ｃｍ３．致密热解碳层的温度范围是１３６０～１４２０℃，根据试验研究所获得的数据进行了工艺设计，实验结果与预期值基本符合。Abstract Dense pyrolyrical carbon layer is anther indispensible layer of coated fuel particle of high temperature gascooled reactor.The function of dense pyrolytical carbon layer in coated fuel Particle and the properties needed are introduced.The relation between pyrolytical temperature and the density, deposition rate and deposition efficiency of the pyrolytical carbon obtained is investigated. The temperature range for obtaining dense pyrolytical carbon layer with density of1.90±0.10g/cm￣3 is between 1360￣1420℃ The result of experiment which is designed according to the data obtained matches up to the expected value.
