A two-wavelength CO(2) laser designed for atmospheric pollution measurements has been used for determining the absorption coefficients of thirteen gas pollutants at CO(2) laser lines between 9.2 microm and 10.8 microm. All measurements were done with the pollutant at a low pressure in the presence of 1 atm of air. Sensitivities of about 5 ppb for a 1-km path have been obtained for ethylene.
一台为大气污染测量设计的双波长二氧化碳激光器，已被用于测定9.2微米至10.8微米之间二氧化碳激光谱线处13种气体污染物的吸收系数。所有测量都是在1个大气压的空气存在下，在低气压的污染物条件下进行的。对于乙烯，在1公里路径上已获得约5 ppb的灵敏度。
