【Abstract】 The paper presents a system of detecting and controlling combustible gaswith a computer which includes magnification, alarm and display circuitsdesigned. The detecting clements are well linked with the computer A - Dconverter. In order to detect the combustible gas density quantitatively, a newmethod of demarcating density is given.更多还原
