摘要
几十年来离子式感烟探测器一直在火灾探测领域占居主导地位，但由于光电式感烟探测器近年来发展使其受到挑战。本文从两者各自探测原理、探测性能的差异、工作寿命诸方面进行分析比较，对于人们就核辐射放射性危害的误解释疑，并就离子式感烟探测器目前自我完善、发展方向和途径作探讨和研究。
Over the last three decades or more,the ionization smoke detector always has been situated in main stream,but in recent years it has met the challenge from optical smoke detector.This paper compares the both detectortypes in explain the misunderstanding from people about working life etc. ,in order to explain the misunderstan-ding from people about the nuclear radiation danger,and probe into the self-perfection and development ofionization smoke detector.
