n.排泄器(喷射器；排放装置；排放管)
This is accomplished by the use of full-length eductor tubes (dip tubes) and gooseneck eductor tubes (see Fig. 1). 这是通过使用全长排放管（汲取管）和鹅颈排放管（见图1）。
A numerical simulation and experimental study was conducted of the exhaust gas eductor of a marine gas turbine. 通过对船用燃机排气引射器的数值模拟及实验研究,确定引射器结构对引射系数的影响,引射器内部的气流参数分布。
Chosen the jet eductor of air bearing equipment,paper introduced the structure、work elements and design method of jet educator. 以气浮设备中的射流器设计为例,介绍了射流器的结构、工作原理和设计方法。
Cylinders with a full-length eductor tube, or what is sometimes called a full-length dip tube, have a tube that runs from the inlet of the cylinder valve to the bottom of the cylinder. 带有全长排放管，或者有时称为全长汲取管的钢瓶有一个从钢瓶入口一直伸到钢底部的管子。
