结果表明，在pH 7.0 Na2HPO4-NaH2PO4缓冲溶液中，AuI4－—CTMAB体系存在粒径约43nm的缔合纳米微粒；在pH3.6-7.0，Au浓度大于0.6×10-5 mol/L，KI浓度大于0.8×10-4 mol/L，CTMAB浓度大于0.8×10-5 mol/L的条件下，AuI4－—CTMAB体系在470nm处的瑞利散射明显增强。

The calculated results indicate that a bifurcated A. wave can be formed when the shock passes through the flame, and pre-induced shock transmission in the flame leads to the formation of Mach stem, followed by spheral shock wave. The Rayleigh-Taylor and Kelvin-Helmholtz instabilities occurred in the flame induced by shock wave lead to the flame distortion and breakup.
