The physical properties of cerarnics are ciosely related to their microstructure such as the grain scale , grain boundny , grain orientation , etc . it ' s helpful for the development
陶瓷的物理性能与其相应的微观结构之间存在着密切的相互联系，如晶粒尺度、晶界、晶粒取向等都对物理性能有影响。
Abstract : in light of thicker grain and smaller viscosity of debris flow , a segmented simulation of the debris flow with flume is presented . for the first time . more difficult resistance similarity is brought about by geometric rate without excessive coarsing and discontinuous similarity of sand grain composition in model is eliminated with different grain scale . on this basis the density similarity and sand conveying similarity are achived . the method presented is verified through a model test case
文摘:针对水石流颗粒粗,粘性小的特点,提出了利用水槽进行分段模拟水石流的设想,首次通过几何变率解决难度较大的阻力相似问题,改变了以往过度加糙的方式;通过变粒径比尺的方法消除了模型沙级配不连续相似的问题,较好地实现了固体物质级配相似,达到了泥石流的密度相似和输沙相似.通过水槽概化模型试验实例,对本方法进行了验证
