针对目前氧化锆氧量仪寿命短、测量不准确的缺点,本文对智能型氧化锆氧量仪进行了深入的研究。
In the domestic factories of twt manufacture , the data of dispersion and interaction impedance are usually obtained by simulation . although the measurement of beam - wave interaction can get the data , which including large and expensive equipments . but it can not find the blemish of sws as early because it must wait until the finishing of whole manufacture
目前,国内行波管生产科研单位基本都是通过软件计算得到慢波结构的色散和耦合阻抗冷参量,或者待整支管子装配完成后,通过热测来估计出慢波结构的色散和耦合阻抗,这样做不但测量不准确,而且也不能及时发现慢波结构的缺陷,浪费了大量人力、财力。
