【Abstract】 J. G. Ramsay has listed a series of equations in his paper "Shear Zone Geometry: areview" to calculate the values and orientations of strain in shear zone. Seven of theseequations whose correctness is doubted have been deduced and proved in a simplermathematical way with corrected forms in this paper.更多还原
