dispersion error (炮彈的)散布偏差。

dispersion zone

Then discusses its properties , such as biased property , relative efficiency of generalized variance and superiority comparisons between generalized ridge estimation and generalized least squares estimation . shows iterative algorithm based on the mean dispersion error 該估計雖然具有偏崎,但其估計精度具有良好的性質,如:有偏性、方差一致最優性、相對于廣義最小二乘估計的廣義方差效率、 mde ? ?有效性等。

The origins of dispersion error are analyzed ; effects of initial velocity dispersion , ballistic coefficient dispersion , drift coefficient dispersion , range wind & cross wind dispersion on the ballistic dispersion are discussed 分析了散布誤差的起源,討論了初速散布、射角散布、彈道系數散布、偏流散布、縱橫風散布對密集度的影響。
