摘　　要：按照国家及相关行业规程对来自太平洋C-C区我国矿区的海洋矿物——天然大洋多金属结核的主要物理特性进行了测定;通过天然结核的沉降试验和浮游速度试验,得到了结核沉降速度和浮游速度的计算方法,分析了颗粒群浓度对颗粒群与单颗粒浮游速度比值和拖曳力系数比值的影响。Key physical properties of natural polymetallic nodules from deep sea of Clarion Clipperton Zone（CCZ） in Pacific Ocean was studied through tests on settling and floating velocity of natural nodules according to the state and related industrial regulations. Based on that, methods for calculating nodule settling and floating velocity were determined,and the effect of particles concentration on the ratio of floating velocity of single particle to floating velocity of granule group,as well as drag coefficient ratio were also analyzed.
