J. Cent. South Univ. (2017) 24: 720-725 DOI: 10.1007/s11771-017-3473-1 Effects of porosity heterogeneity on chemical dissolution-front instability in fluid-saturated rocks ZHAO Chong-bin(赵崇斌)1... the heterogeneity of porosity obeys the random uniform distribution, both the mean value and the variance of porosities in the heterogeneous porosity field can be used to reflect the overall heterogeneous......
J. Cent. South Univ. (2017) 24: 2396-2405 DOI: https://doi.org/10.1007/s11771-017-3651-1 Stress dependent permeability and porosity of low-permeability rock JIA Chao-jun(贾朝军)1, 2, XU Wei-ya(徐卫亚)1... test system, both permeability and porosity of granite from an underground oil storage depot were measured. In order to study the influence of rock types on permeability, a tight sandstone......
J. Cent. South Univ. (2020) 27: 592-607 DOI: https://doi.org/10.1007/s11771-020-4319-9 Effects of axial static stress on stress wave propagation in rock considering porosity compaction and damage... influences stress wave propagation characteristics of porous rock by varying the level of rock porosity and damage. Moreover, the initial porosity, initial elastic modulus of the rock voids and skeleton......

Effects of cathodic component of current on porosity and hardness characteristics of micro plasma oxidation(MPO) coatings on aluminum alloy Samir Hamid Awad, QIAN Han-cheng(钱翰城) (School... quality coatings. The main research emphasis in MPO coating development over the past years seems to be the attainment of higher hardness levels and thick coatings. The porosity of MPO coating......
Effect of porosity on wear resistance of SiCp/Cu composites prepared by pressureless infiltration ZHANG Lin(章 林), QU Xuan-hui(曲选辉), DUAN Bo-hua(段柏华), HE Xin-bo(何新波), QIN Ming-li...; Abstract: The influence of porosity on the wear behavior of high volume fraction (61%) SiCp/Cu composite produced by pressureless infiltration was studied using a sliding, reciprocating......
J. Cent. South Univ. (2017) 24: 977-987 DOI: 10.1007/s11771-017-3500-2 Porosity of crushed rock layer and its impact on thermal regime of Qinghai-Tibet Railway embankment LIU Ming-hao(刘明浩)1, 2, LI... porosity of the rock layers. However, due to the strong winds, cold and high radiation conditions on the Qinghai-Tibet Plateau (QTP), both wind-blown sand and/or weathered rock debris blockage might......
