功率行波管中使用的螺旋线夹持杆,其导热率的优劣,无疑是一个十分重要的问题。虽然测量各种材料导热率已是一个基本上解决了的问题,但由于要提供特殊的标准试样,需要专门的测试条件,对行波管研制者来说,为能及时得到夹持杆的导热性能和数据,殊感不便。本文根据夹持杆有细长的特点,提出了相对测量方法。若建立标准样品,亦可进行绝对测量,方法简便可靠。此方法可用于各向同性的夹持杆,如石英、氧化铝、氧化铍等。
Power traveling wave tube used in the spiral clamping rod, the pros and cons of thermal conductivity is undoubtedly a very important issue. Although the measurement of thermal conductivity of various materials has been a problem that has been basically solved, due to the need to provide a special standard sample, the need for specialized testing conditions for the TWT developers, in order to get the gripper rod Thermal conductivity and data, special sense of inconvenience. In this paper, according to the slender rod features, the relative measurement method is proposed. If the establishment of standard samples, but also for absolute measurement, the method is simple and reliable. This method can be used for isotropic holding rod, such as quartz, alumina, beryllium oxide and so on.
