摘　　要：固体浮力材料是现代深潜技术的重要组成部分之一,是深潜器设计装备的六大关键技术之一,也是海洋勘察及深海工程中最普遍应用的一种材料。这种材料主要是为深海装置提供浮力,以实现深海装置的悬浮定位,无动力上浮下潜,增大有效载荷,减少外型尺寸。固体浮力材料在应用到深水装备之前,需要对其关键性能指标进行检验,包括密度、高压吸水率和体积弹性模量等,以保证深水装备的安全使用。其中,体积弹性模量的检验则是一个技术难点。鉴于此,本文综述国内外固体浮力材料体积弹性模量的测试方法,包括仿真计算法、超声测量法和高压原位测试法,为水下装备设计开发人员提供参考。Solid buoyancy materials are one of the important components of modern deep-diving technology,one of the six key technologies in the design and equipment of deep-sea vehicles,and the most commonly used material in marine surveys and deep-sea engineering.This material mainly provides buoyancy for the deep-sea device to realize the floating positioning,floating up and down without power,increasing the effective load and reducing the size.Before solid buoyancy materials are applied to deep-water equipment,their key performance indicators,including density,high-pressure water absorption,and bulk elastic modulus,need to be tested to ensure the safe use.Among them,the inspection of bulk elastic modulus is a technical difficulty.In view of this,this article reviews the testing methods of bulk elastic modulus of solid buoyant materials,including:simulation calculation method,ultrasonic measurement method and high-pressure in-situ testing method,to provide references for underwater equipment design and development personnel.
