The research on the rock burst prediction was made on the basis of seismology,rock mechanics and the data from Dongguashan Copper Mine (DCM),the deepest metal m
A new multifunctional mPEG-b-PAA-grafted chitosan copolymer possessing amino and carboxyl groups, mPEG-b-PAA-g-CHI (compound 6), was designed for a potential ap
Hydration products and morphology characteristics of C3A (tricalcium aluminate)-CaCO3-H2O system were studied by means of XRD, DSC, FTIR spectrum analysis and S
The location of a moving target based on signal fitting and sub-aperture tracking from an airborne multi-channel radar is dealt with. The proposed approach is a
Acoustic emission tests of the core specimens retrieved from boreholes at the depth over 1000 m in Hongtoushan Copper Mine were carried out under uniaxial compr
In light of the problems of low-quality and low degree of comprehensive utilization of Guangdong muscovite-type kaolin,the reasons affecting the quality of kaol
In order to numerically simulate the failure process of rock and concrete under uniaxial tension,an improved method of selecting the mechanical properties of ma
The influence of heterogeneity on mechanical and acoustic emission characteristics of rock specimen under uniaxial compress was studied with numerical simulatio
Experiments on silt incipient motion under wave action were carried out. Under wave action, for different wave periods, water depths and bulk densities of silt,
