| 摘 要： | 实验采用了适当配比的塑化松香 ,模拟岩石圈延性层 ,研究边界驱动条件下塑性流动波的传播过程。实验表明 ,塑性流动波类似于粘性重力波 ,并有“快波”和“慢波”之分 ,二者分别由主波和辅波叠加而成。主波类似于孤立波或涌波。根据相似原理 ,“快波”主波的外推波速约为 0 .12～2 .5km/a ,在波速量级上大致相当或接近于岩石圈下层某些控制地震迁移的塑性流动波

| Abstract: | In order to study the propagation processes of plastic-flow waves in the lithosphere, plasticized rosin, i.e. the mixture of rosin (R) and plasticizer (P ) with proper ratio of P/R, is used as analogue material for modeling ductile layer in the lithosphere. The mixture is poured into a rectangular shallow trough (280～300mm long and 190～200mm wide), forming ductile one layer model (1) with a thickness of 8～9mm, as shown in Fig. 1. The bottom (2) and walls (3 and 4) of the trough are made up of gl |
