摘要
环境监测数据是环境保护工作的基础,监测仪器设备的精良及监测方法的科学性则是获得优质数据的保障工具.本文运用数学方法对目前广泛使用的采样仪器进行了采样误差的分析研究,指出了改善仪器和改善监测方法去获取更精确数据的途径.
The sampling error of instruments which arc used widely in sampling was studied and analysed with mathematical method. The approach of dc. vcloping the sampling instrument and improving the monitoring method for getting correct and re-liable data was presented.
