摘　　要：利用正比计数管测量了氦基混合气体He/C3H8(60/40)在55Fe 5.9keV X射线下的气体增益,并对气体增益随高压、温度、气压及气体比分的变化作了研究.作为比较还对He/CH4(60/40)及Ar/CO2/CH4(89/10/1)混合气体进行了相应的测量.Using a proportional tube, the gas gain of the helium-based gas mixture He/C3H8(60/40) was measured with 55Fe 5.9 keV X-ray source as a function of the anode wire high voltage, gas temperature, gas pressure and gas mixture ratio. The gas mixtures of He/CH4(60/40) and Ar/CO2/CH4(89/10/1) were also tested for comparison.
