| 4 | 主喜马拉雅逆冲断裂的横向变化控制2015年尼泊尔廓尔喀地震的破裂长度显示文摘喜马拉雅造山带大地震活动频繁,影响着长达2500km的人口密集地带。2015年尼泊尔廓尔喀地震(MW7.8)发生在主喜马拉雅逆冲断裂(MHT)上,为陆陆碰撞带断裂活动特征的研究提供了最直接的观测资料。我们使用覆盖整个余震区的近震台站地震波形数据对MHT进行研究。结果表明,MHT沿构造走向呈现清晰的横向变化,在主震区存在低喜马拉雅断坡,而在余震区东部变得更深且倾角更加平缓。余震区以东MHT界面上的地震波速表现为高速异常,可能与印度板块基底隆起的俯冲结构有关,余震区以西同样存在地震波速异常。MHT的总体形态结构变化控制了廓尔喀地震的破裂长度。 | L.Bai S.L.Klemperer J.Mori M.S.Karplus L.Ding H.B.Liu G.H.Li B.W.Song S.Dhakal 江勇(译) 李国辉(译) 白玲(校) | 2020 | 世界地震译丛2020，51，1： | 0 |
| 5 | INFLUENCES OF MICRO-ALLOY AND HEAT-TREATMENT PROCEDURE ON THE HARDENING OF DJ108TI ALLOY显示文摘The influences of micro alloy and heat treatment procedure on the hardening of DJ108Ti alloy, which is based on the electrolytic Al Si(2 05%) Ti(0 25%) Fe(0 30%) multi component alloy, have been investigated. The results indicate that the micro alloy based on the multi component alloy makes α Al dendrites in DJ108Ti alloy refined; that the improved heat treatment procedure makes the eutectic Si phases granulated , the Fe phase refined, and the strengthening phases of Mg2Si and Al2Cu fully precipitated. The micro alloy and the heat treatment procedure harden DJ108Ti alloy and benefit the abrasion resistance of the | Z.Y.Liu,X.Q.Wang,Y.T.Wang,M.X.Wang,G.S.Wang and G.H.Li Material Physics Laboratory, Zhengzhou University, Zhengzhou 450052, China | 1999 | Acta Metallurgica Sinica(English Letters)1999，12，5： | 0 |
