构造了一种带单电阻阳极线的电荷分划式位置敏感比例计数器，用于测量管道中流动或扩散的3H标记气体的运动。在阳极线和前置放大器之间引入电阻，使整个计数器对3H β射线的检测效率保持一致。位置分辨率为3.1mm FWHM。在阳极总长度为740 mm的700 mm范围内，检测效率几乎100%均匀。3H标记气体的运动。可以有效地测量。
A position sensitive proportional counter of a charge division type with a single resistive anode wire was constructed for the measurement of the movement of 3H labelled gas which is flowing or diffusing in a pipe. The introduction of resistors between the anode wire and pre-amplifiers brought a uniform detection efficiency for 3H β-rays throughout the counter. The position resolution was 3.1mm FWHM. Detection efficiency was almost 100% uniformly over about 700 mm in the total anode length of 740 mm. The movement of 3H labelled gas. could be measured effectively.
