【摘要】 以双能 γ射线透射法用于煤矸石在线识别系统中的组分测量为例，对由被测物组分变化引起的动态测量误差的成因进行了阐述，并就各相关参量对误差的实际贡献作了分析讨论，得出用缩短采样周期时间来有效减小误差的结论．更多还原

【Abstract】 According to a detail example of the identification for coal gangues based on dual energy γ ray transmission, the origins of dynamic error caused by the component’s variety are proposed. The interrelated parameters contribution to this error is discussed. As a result, shortening the sampling can minify the error.更多还原
