And it can be used in many fields. We study on the law of Q M responding to expiratory gases. Using a computational chemistry method, we can easily design sensitive film of sensor, and make it by the electropolymerization theory We also design a measurement systems and use a IEEE. 488 card to connect measurement equip- ment. And we get the response data of expiratory gases from the Q M gas sensor. So we have the conclu- sion that the Q M gas sensor can be used in measuring acetone gas in breath. :　 ; ; Key words quartz crystal microbalance computational chemistry electropolymerizating film Q M① 徐良,余皓,王平 (,,, 310027) : Q M ( Quartz rystal Microbalance) .、 、,,,. ,,. ,. : Q M;; : 　　　: A　　　: 1005- 9490(2002)01- 0077- 06 1995 1　　 ,.
