一：magnetron是什么意思（中英文）解释的意思：

magnetron是一种电子器件，主要用于产生微波。它由一个空心的金属管和一个带有孔的阴极构成，当高压电流通过阴极时，产生的电子束在磁场的作用下被弯曲并聚集在管内，从而产生微波辐射。

Magnetron is an electronic device that is used to generate microwaves. It consists of a hollow metal tube and a cathode with holes. When high voltage current passes through the cathode, the electron beam is bent and focused inside the tube under the influence of a magnetic field, thus producing microwave radiation.

二：怎么读（音标）：

magnetron [ˈmæɡnɪtrɒn]
