Get the effective bulk modulus and shear modulus of effective medium(Calculate the effective bulk modulus and shear modulus of the two-phase effective model by using of Berryman's SCA and DEM(1990,1992) model.)

第二种模型下的sca和dem函数，应用于试验不同方法下岩石物理模型(The SCA and DEM functions under the second models are applied to rock physics models under different test methods.)

应用于岩石物理模型中的函数计算，可适用于各向同性和各向异性(The calculation of functions used in rock physics models can be applied to isotropy and anisotropy.)
