three-colour tube

A color television tube in which three primary colors are combined to give the full range of colors.

用三种基本颜色组合起来的能显示各领域颜色的电视显象管。

Material tube can move forth and backward, it facilitates the cleaning of hopper. Three ( four)-step thermal controller is better for shaping.

料管可前后移动，清料及更换料头方便，螺杆三（四）段温度控制，使之塑化效果更好。

T-tube radiator weld seam is a complex three-dimensional space curve and there is aluminum wing obstacle at vertical direction, interference phenomenon between risers at horizontal direction. It is difficult to achieve automatic continuous welding.

散热器T型管焊缝是一个复杂的空间三维曲线，并且在竖直方向上存在铝翼障碍、水平方向上存在多立管之间的干涉障碍，难以实现自动化连续焊接。

Described is an equipment consisting of several systems as follows: an ion system, having a sputtering ion source and an asymmetric three electrode acceleration tube, operated at 50 keV with a beam current up to 4 mA ( for N+);

本设备由以下系统组成：注入系统，有溅射离子源及不对称三电极加速管，能量50keV，流强4mA（N~+）；
