摘要：
In the present study, the coal on-line analysis system is optimized, and the signal-to-noise ratio (SNR) is quantified and set as the evaluation criterion for device optimization. 3 cm lead with 3 cm polyethylene is set as moderator, and 13 cm lead is for a better shielding. Besides, the neutron generator is set at the center of device, and 72 cm is set as the better distance of axis between neutron generator and detector. Finally, by comparing with the previous experimental results, the Mean Absolute Percentage Error of element with the value less than 1% is improved after device optimization by SNR evaluation.
