我们在《模拟量离子感烟探头及标定的设计》(刊于本刊 2 0 0 0年第 1 1期 )一文中曾指出 ,要真正实现模拟量报警 ,探头的烟浓度探测信号输出应满足三个条件 ;其中头两个条件已由探头的设计及其标定法予以满足。本文再对计量的线性度等其它问题予以讨论。离子感烟探测器的烟浓度 We have pointed out in the article entitled “Analog ion-sensing smoke probe and calibration design” (published in the first issue of 2001) that in order to truly simulate the alarm, the probe’s smoke detection signal output should meet Three conditions; the first two conditions have been met by the probe design and calibration. This article discusses other issues such as linearity of measurement. Smoke concentration of ion smoke detector
