tube solenoid的意思|示意

The magnetic field intensity of the solenoid used for travel wave tube and transport properties of electron beam in the slow wave system under its function is simulated with the electromagnetic code.

利用电磁场软件模拟了行波管电磁线包磁场，以及在电磁线包磁场作用下电子注在慢波系统中的运动特性。

In this system, many transparent tubes filled with liquid are used for background, and there is a solenoid valve at the bottom of each tube, which can produce bubbles in the tube.

这种成像系统以充满液体的透明管作为背景，通过电磁阀向管中通入气体来表示像素点，从而进行二值图像的显示。

Air source treatment unit, solenoid control element, actuation element and tube fitting.

气源处理元件、电磁控制元件、执行元件、管接头等。
