一、引言火炮镜炮同步误差测量装置是测量火炮火线和瞄线同步性误差的专用测试设备,其测量结果的准确与科学描述,对于型号试验具有重要指导作用。一般测量结果是由测量结果的最佳估计值及其测量不确定度来完整表述的,火炮镜炮同步误差测量结果应包括测量结果的最佳估计值,还要包括测量结果的不确定度,才能完整表述火炮镜炮同步误差的测量结果, I. INTRODUCTION The artillery cannon synchronization error measuring device is a special test equipment for measuring the synchronism error of firewire and aiming line of artillery. The accurate and scientific description of its measurement result has an important guiding role for the type test. General measurement results are the best estimates of the measurement results and their measurement uncertainty to complete the description of the artillery gun synchronization error measurement results should include the best estimate, but also to include the uncertainty of the measurement results, In order to fully describe the artillery gun error measurement results,
