| 摘 要： | 针对TJ-1模拟月壤颗粒级配跨度大、粒径〉2mm．的颗粒含量多，采用常规方法制备空心圆柱试样容易出现粗细颗粒分离、试样整体不均匀的特点，提出改良型制备方法．首先采用分层欠压法与冰冻法相结合制备出孔隙比e=1．0的实心圆柱试样，并对实心样的均匀性进行评价，得到分层制备相同孔隙比的TJ-1模拟月壤均匀试样时每层试样的高度；...

| Abstract: | As the conventional preparation method of making hollow cylinder specimen is not suitable for TJ-1 lunar soil simulant due to its broad span of size distribution and including a mass of particles whose diameters are larger than 2 mm,one kind of adjusting preparation method was brought forward.Firstly,the solid cylinder specimens with a void ratio e=1.0 were prepared by using the multi-layer with undercompaction method(UCM).And then the uniformity of the specimens was evaluated with the application of freezi... |
