摘　　要：该文提出了一种研究螺旋线行波管慢波系统散热性能的综合分析方法。该方法以一定的预备实验为前提条件,利用理论公式推算出接触处的界面热阻率,使用仿真软件进行精确的模拟研究。该方法可以准确的反映慢波系统的散热性能,可以降低实验成本,节约材料,节省实验时间。通过对采用氧化铍夹持杆、氮化硼夹持杆和镀铜螺旋线的慢波组件的研究,验证了该方法的一致性和可行性。A novel, effective and synthetic analysis method is developed for studying the heat dissipation capability of slow-wave structure. This method, based on some theoretical and experimental research, is applicable to analyze the thermal conduction precisely and truly. This method can reduce the material costs and save the involved time. The consistency and the feasibility of this method are verified by some experimental tests on the slow-wave structures with BeO support rods, BN support rods and copper-plated helix.
