一、引言磁控管有重量轻、体积小、效率高的特点.它在雷达、导航、微波加热等方面有着广泛的应用.虽然人们对磁控管已经研究、制造和应用了几十年,但至今对它的工作原理还没有完全认识清楚.有人认为:“磁控管象一匹野马,很难驾驭.”还有人认为:“在研究磁控管时,当你刚要形成一个有规律性的概念时,马上就会观察到新的现象,把你刚要形成的概念否定了.”在国际上,磁控管的工作原理也被认为是个难题. I. INTRODUCTION Magnetron has the characteristics of light weight, small size and high efficiency, and it has a wide range of applications in radar, navigation, microwave heating, etc. Although people have been researching, manufacturing and applying magnetron for several decades, But so far its working principle is not fully understood.People think: “magnetron like a Mustang, it is difficult to control.” Some people think: “In the study of magnetron, when you just want to form a regular Sexual concepts, new phenomena are immediately observed and the concepts you just formed are denied. ”Internationally, the working principle of magnetrons is also considered a dilemma.
