Long tubes ( instead of bulbs ) that produce light. 长条管(代替灯泡)发光。
For the latter, a pneumatic multiplier and an approximate dead-time element using long tubes are presented. 属于后者的是气动乘法元件和以长导管构成的近似纯滞后元件。
In order to process efficiently inner surface modification in thin long tubes by means of this technology, the physical problems of plasma in a thin long tube need to be researched. 为了使等离子体材料表面改性技术能够在细长圆管内壁有效进行,需要研究的物理问题是细长圆管内等离子体的产生机制及产生的等离子体物理性质。
In recent years, the technology of plasma surface modification is widely in demand in many areas. However, treating the inner surface of tubes by the same processing has encountered difficulties, especially for inner surface modification in thin long tubes. 近年来,等离子体材料表面改性技术在许多领域中被广泛需求,但是对圆管内壁进行这样的处理遇到了一定的困难,特别是对细长圆管内壁进行表面改性变得更加困难。
The hot-dip galvanization furnace ( bath ) plays a critical role in hot-dip galvanization of steel tubes f particularly long tubes. 热镀锌炉(锅)是钢管热镀锌生产的重要设备之一,对镀制长度较大的钢管,其作用更为突出。
