摘　　要：由于气体泄漏事故具有隐蔽性和突发性,往往需要借助反演算法确定泄漏位置和泄漏源强,而现有方法存在初值敏感、收敛较慢等问题。提出了一种结合差分进化和模式搜索算法的DE-PS混合算法,可用于在应急情况下快速且准确地反算泄漏气体的位置和源强。DE-PS混合算法既避免了DE收敛过慢,又避免了PS对初值敏感的问题,混合算法的计算速度更快,误差更小。Since gas leakage accidents are concealed and sudden,it is often necessary to use the inversion algorithm to determine the location and the source strength of the leak.However,existing methods have problems such as initial value sensitivity and slow convergence.This paper proposes a DE-PS hybrid algorithm combining differential evolution algorithm and pattern search algorithm,which can be used to quickly calculate the position and source strength of leaking gas in emergency situations.The DE-PS hybrid algorithm not only avoids the slow convergence of DE,but also avoids the problem that the PS is sensitive to the initial value.The hybrid algorithm has faster calculation speed and higher precision.
