In this article , technical transformation in longxin mining company adopted cip process instead of all - sliming cyanidation - zinc dust replacement method , fracture breccia ores are treated , and good technical economic indexes have been attained 摘要龙鑫矿业公司通过技术改造，采用炭浆法代替原有全泥氰化锌粉置换工艺，处理破碎角砾矿石，取得了良好的技术指标和显著经济效益。
Surface wave velocity detecting tests and dry density detecting tests by pit replacement method were conducted respectively for the transient material ( a ) and main rock - fill material ( b ) used in the construction of concrete - faced rock - fill dam of shuibuya project 摘要以水布垭面板堆石坝施工中的过渡料( a )和主堆石料( b )为主要检测对象，分别进行了面波波速和试坑置换法干密度的对比检测试验。
The nonlinear magneto - elastic basic equations of thin current - carrying strip - plate are built , based on the kinetic equations , the geometric equations , the physical equations and the electrodynamics equations of thin current - carrying plate , the normal cauchy form nonlinear differential equations , which includes ten basic unknown functions in all , are obtained by means of variable replacement method 摘要在所建立的载流条形薄板的非线性磁弹性基本方程运动方程、几何方程、物理方程和电动力学方程的基础上，通过变量代换，整理成含有10个基本未知函数的标准柯西型方程。
During the experiment of protein crystal growth in space carried by chinese re - entry capsule fsw - 2 , the crystals of barheaded goose hemoglobin suitable for x - ray analysis were obtained both in space and earth as contrast group . the diffraction data of both crystals were collected , and the structures were solved using molecule replacement methods . the comparison of structures in space and earth indicate that , the interactions among molecules in crystal and subunits of molecule in space is weakened relative to the crystal on earth , there is a contact in the 在1994年我国返回式卫星fsw - 2上进行的空间蛋白质晶体生长实验中，获得了适合于x射线分析的空间实验组和地面对照组的斑头雁血红蛋白晶体，并收集了x射线衍射数据。应用分子置换法解析了结构，并进行了比较研究。结果显示空间晶体的分子间和分子中亚基间的相互作用趋于减弱，在
