在地壳和地幔剪切带中的熔化过程大概是很复杂的。目前提出的那个模型是比较普遍的.在这个模型中,产生扩散体系的两部分之间存在着一个坚硬的非均匀受压的隔层。无论是在卡姆布(Kamb)的模型里还是在目前所提出的这个模型中,据推论,受压固体中某一组份的化学势均为: μ=μ~0+VP_1_+1/2p_1e_iV_0 (1) 式中μ~0为取自某种标准状态下的化学势,VP_1 The melting process in the crust and mantle shear zones is probably quite complicated. The model currently proposed is quite common: in this model, there is a hard, non-uniform, compressive barrier between the two parts of the diffusion system. Whether in Kamb’s model or in the current model proposed, it is inferred that the chemical potential of a component in a pressurized solid is: μ = μ ~ 0 + VP_1_ + 1 / 2p_1e_iV_0 (1) where μ ~ 0 is the chemical potential taken from some standard state, VP_1
