摘　　要：已有的海底热液活动模拟实验装置主要通过控制流体的温度和压力实现热液活动环境下的水岩反应实验,随着近年来对海底热液活动研究程度的逐渐深入以及热液保真采样器等新技术的应用,有必要设计新型的海底热液活动模拟实验装置。为此,我们设计了一种可以模拟海底热液环境的实验装置,该装置主体由两个圆柱形钛合金舱体对接而成,利用加热装置、加压装置、流体输入装置以及相应的计算机装置控制实验舱体内的环境参数(温度和压力等)和流体状态,实验舱体的侧壁和两端都根据需要设计了连接环境和化学探测传感器的接口。试验结果表明该实验装置能够进行海底热液活动环境下的水岩反应实验和热液羽状体的扩散模拟实验,同时可实现与我国自行研制的热液保真采样器的连接。Most of the hydrothermal simulation reactors for modeling the water-rock interaction in sea- floor hydrothermal systems were designed by regulating temperature and pressure. Since the shifting of research interest to hydrothermal plume and the wide application of hydrothermal fluid sampler with fidelity recently, the new experimental simulation reactor is in high demand, which should not only keep the functions of the existing reactors, but also have the advantage to simulate the hydro- thermal plume and be connected with the sampler with fidelity. We designed and tested a new experi- mental simulation reactor recently. The main part of this reactor is composed of two columned titani- um cabins. The environmental conditions, such as temperature, pressure and fluid, can be regulated by means of the heaters, pressure devices,inputting devices and associated computers. The sides and ends of the reactor are specially designed to be able to connect with physical and chemical electrodes. Meanwhile, the China made hydrothermal sampler with fidelity can be successfully connected with this experimental simulation reactor. The test results indicated that the experimental simulation reac- tor can be used to simulate the water-rock interaction and hydrothermal plume processes which have been observed under modern seafloor hydrothermal conditions.
