摘　　要：本文给出了一种二维地电模型有限元网格自动形成方法,并详细介绍了该方法的数学模型及程序框图。The Paper presented a method for au-tomatic drawing of finite element grid of two-dimentional geoelectric model,described indetail its mathematical model and programchart.A Study on Optimal Selection of the Impre-gnated Diamond Bits With Multifactor pre-prendicular Experimental Method——The mainphysico-mechanical properties of the typicalocks in western Henan were tested in the re-search,then determined the indices for bit str-ength of wear and drilling speed by the micro-bit simulated drilling test,proposed metho-ds for optimal selection of design parametersof impregnated diamond bits on the basis of per-pendicular analysis and comprehensive evalua-tion.
