Firstly , the author , in this essay , has proceeded from the compiling principles of the trajectory report and the actual situations of the field troops , analyzed the defects and shortcomings of the present compilation of the trajectory report , and described systematically the principles and procedures of computing the layer power by the methods of statistical analyses . thereupon , a complete model of computing the layer power has been established and the computation results of the proximate layer power have been found out by simplified process . secondly , the comparison computation has been conducted in accordance with the paired projectiles of 122mm , 152mm and 155mm guns equipped in our army , and test and analyses of the research results have been carried out 论文中,作者首先从弹道通报的编制原理和部队的实际使用情况入手,分析其缺陷,进而结合统计分析的一般方法系统地描述了计算层权的原理及过程,建立了计算精确层权、近似层权的完整模型,并通过计算与统计,详细给出了专用及通用近似层权的计算结果,然后针对我军装备的122mm 、 152mm 、 155mm弹丸进行对比计算,对研究结果进行了检验与分析;最后,针对计算机气象通报的特点,论证了对其作进一步改进的可行性与必要性,提出了相应的措施。
