摘要

There will be great number of settleable residues during shooting of firearms. In traditional smoke chamber-detection, taking smoke chambers before and after shooting as the data test environment may affect the detection result. Considering this, we propose to measure data in a smoke-free environment created by automatically discharging smoke in detection system after analyzing the impact of settable residues on detection results, which may effectively avoid such impact. Results of detection of transmittance of muzzle smokes of 5.8mm and 7.62mm ordinary guns indicate that average efficiency of transmittance of improved detection method is improved by 3.04% and 3.09%, standard deviation decreased by 0.0117 and 0.0079 respectively compared with traditional detection method, with improved reliability, reduced detection time and significantly enhanced detection efficiency.
