1 前言浊流的折射和反射已被引用来解释现代和古代深海海盆中沉积物(Van Andel 等,1969);这些浊流已在水槽实验中进行模拟(Pantin 等,1987;等),提出了浊流向上坡流动的机理,沉积在西赤道大西洋西阿拉海隆(Damth 等,1979),地中海海岭的北侧(Cita 等,1984),巴巴多斯加增生柱前缘附近的蒂布龙海隆(Dolan 等,1989),中美洲海沟的外坡 1 Introduction Refraction and reflection of turbidity currents have been cited to explain the sediments in modern and ancient deep-sea basins (Van Andel et al., 1969); these turbidity currents have been simulated in sink experiments (Pantin et al., 1987; The mechanism of turbidity flow upwelling was deposited on the western equatorial Atlantic shores of Alhaleca (Damth et al., 1979), on the northern side of the Mediterranean Ridge (Cita et al., 1984), on the Tybroon seamounts near the augmentation column of Barbadosga (Dolan et al. , 1989), the outer slope of the Central American trench
