本文提出了利用特征时间测量爆高的新机理和测量模型,依据核爆炸双光峰的物理特性,巧妙地给出了近似解,得到良好的估测爆高结果,并作出图形显示。估算爆高的最大绝对误差为33m,对实际爆高相对误差小于6%。 In this paper, we propose a new mechanism and measurement model to measure the explosion height by using the characteristic time. According to the physical characteristics of the double light peak of the nuclear explosion, the approximate solution is given cleverly, and a good estimate of the blast height result is obtained and a graphic display is made. The maximum absolute error of the estimated blast height is 33 m, and the relative error to the actual blast height is less than 6%.
