Stress Field of Straight Edge Dislocation in Magnetic Field

To study the changes in mechanical properties of materials within magnetic fields and the motion of dislocations, stress fields of dislocation in magnetic field need to be calculated. The straight edge dislocation is of basic importance in various defects . The stress field of straight edge dislocation in an external static magnetic field is determined by the theory of elasticity and electrodynamics according to the Volterra dislocation model for continuous media. This reduces to the known stress field when the magnet field is zero. The results can be used for further study on the strain energy of dislocations and the interactions between dislocations in magnetic fields.     

黑龙江258岩金矿床地质特征及找矿潜力研究

258高地岩金矿体产于侏罗世花岗闪长岩侵入体中,金矿体呈北西向雁行式排列,含矿岩石为碎裂蚀变花岗岩,围岩蚀变为强硅化、黑云母化、钾化等。该矿床为与闪长玢岩侵入体相关的斑岩型铜金矿床,笔者对矿区内地质、物探和化探进行了综合的分析研究,认为该区具有较大的找矿前景。     

超细复合粉和煤矸石在巷道铺底中的应用研究

为探究超细复合粉和煤矸石在煤矿巷道铺底混凝土中应用的可行性，进行了多比例掺量试验和混凝土强度试验。试验结果表明，混凝土配比中掺加超细复合粉可显著提升混凝土后期抗压强度，搭配煤矸石配合使用可保证混凝土标号不下降；结合原料化验数据对超细复合粉和煤矸石的作用机制和掺配方案进行分析，为超细复合粉和煤矸石在巷道铺底中的应用和推广提供了数据支持。
