【摘要】 提出并证明了γ射线透射组分测量中动态误差的存在，还推导出其时间特性。针对统计误差与动态误差在测量时间上的矛盾关系，文中提出了一种在不增大统计误差条件下减小动态误差的采集与运算方法，并通过实验证实了MCI方法的有效性。更多还原

【Abstract】 The paper verifies the existence of dynamic error in the constituent measurement of coal and gangues based on gamma-ray trans-mission and derives its time property. Aiming at the contradiction between the statistic and dynamic errors in time measurement, the paper presents the MCI method of data collection and calculation that can reduce the dynamic error while the statistic error is not enlarged, then experimentally verifies the effectiveness of the method.更多还原
