| Abstract: | Based on reference1],this paper studies further the spheroidal displacement caused by point dislocations in a SNREI model.The solutions of the equations of equilibrium when an arbitrary point dislocation source approaches to the earth's surface,and some techniques for integrating the equations of equilibrium and summing the harmonic solutions are also discussed. For 1066A earth model,the results.of the dislocation Love numbers of 4 types of dislocation sources are given at depth 5,10, 32,100,30O and 637km,respectively. |
