摘要
针对炮口测速精度交验中存在炮口测速、雷达测速和激光幕测速数据个别偏差较大的问题,从数据统计方面提出一种科学合理的数据判别方法。该方法是以试验数据为依据,利用格拉布斯、肖维涅和狄克逊等检验方法,对当组异常初速数据进行剔除。研究结果表明该方法切实可行,保证了初速数据的准确性。
Aimed at the problem that the several data deviations including muzzle velocity measurement, radar velocity measurement and laser screen velocity measurement were bigger, from the viewpoint of data statistics, a kind of scientific and reasonable data discriminating method was presented. Based on the ex perimental data, by use of Grubbs check method, Xiaown check method, Dixon check method and so on, the abnormal data were excluded. The research results showed that this method can be feasible to meet engineering and practical requirements and ensure the accuracy of muzzle velocity data.
