【摘要】 本文利用模拟气体环境的恒定装置,以液化石油气为可燃气体,使用气相色谱外标定量法,测定了可燃气体报警器的报警范围和最低报警点的可燃气体浓度。此方法在测定范围内线性良好,最大相对偏差0.9％实际测定获得满意结果。更多还原

【Abstract】 In present paper,the alarming range of flammable gas alarm and flam-mable gas concentration of the lowest point are determined with an equip-ment which imitates gas environment and uses liquefied petroleum gas as flammable gas,and gas chromatoraphy calibration curve method.The me-thod is linear well in deternining range,and the largest relative error is 0.9%.the result is satisfing.更多还原
