摘　　要：研究慢波系统的散热性能对改善螺旋线行波管的各项特性具有十分重要的意义。综合叙述了在慢波系统的散热性能影响因素和改进手段方面的研究结果。介绍了新型装配方法和金刚石材料在慢波系统制备中的应用,对各种方法的效果进行了分析比较,并指出新方法和新材料的采用有效的提高了散热性能,促进了更高性能的行波管的研制。The latest development in the heat dissipation capability of helix traveling wave tube （TWT） slow-wave structure （SWS） was tentatively reviewed. The discussions centered on the impacts of various factorssuch as the materials of the componentsgeometries of the installation rodsheat resistance of contacts and assembly techniqueson the heat dissipa- tion capabilityand on the newly-developed solutions for the technical problems involved. Emphasis was given to the high technologies available： including the novel assembly methodsapplications of advanced materials with high therrnal conduc- tivity and better heat dissipation capabilityincluding man-made diamond materialsand the design and manufacturing con- siderations in fabrication of the helix TWT SWS. The development trends and possible improvement in the area was also briefly discussed.
