| 1. | The asthenosphere corresponds approximately to the low-velocity zone .
软流圈，大体上相当于低速带。 |
| 2. | Below the lithosphere is the rheosphere comprising partly fused peridotite .
岩石圈之下是由部分熔融的橄榄岩所组成的软流圈。 |
| 3. | The plates move slowly and continuously on the atmosphere , a layer of hot , soft rock in the mantle
板块缓慢连续地在软流圈上移动，该软流圈是指地幔中炽热柔软层。 |
| 4. | The transverse and vertical variation of qb are very clear in the 3d calculation in the whole area , and the asthenosphere and some big structure arae is also showed very clearly
结果显示研究区域的日横向、纵向变化非常显著，软流圈结构能够明显区分出来，各个大构造单元的q结构呈现出显著的变化。 |
| 5. | The trace element compositions and sr - nd isotopes suggest that the upper mantle beneath the studied area were subjected to multiple episodes of metasomatism , probably by small melt fractions derived from the asthenospheric mantle
微量元素和sr - nd同位素特征表明该区上地幔经历了多期地幔交代作用，交代介质可能是源自软流圈的小体积熔体。 |
| 6. | Partial melting of the enriched lithospheric mantle owing to a raised geotherm caused by lithosphere thinning and following the afc process resulted in the formation of the quannan and tabei syenites in southern jiangxi
随着拉张作用加强，受软流圈物质交代过的岩石圈地幔的小比例部分熔融形成的高钾碱性岩浆经afc作用形成碱性杂岩(全南和塔背岩体) 。 |
| 7. | The distinct spatial distribution of the tholeiitic and alkali basalts at datong may be related to the effect of local lithospheric extension on the passive upwelling of asthenosphere and variable extents of interaction between lithosphere and asthenosphere
大同两类玄武岩在空间上分野明显，可能与桑干河断裂对软流圈地幔上涌的控制以及区域上岩石圈-软流圈作用程度的变化有关。 |
| 8. | The surface loading of the mountains and the associated root of thickened crust produce horizontal deviatoric tension in the strong upper crust . in contrast , the deep , dense lithospheric root and its associated downflexing of the surface produce horizontal compressive deviatoric stress in the strong near - surface layer . the actual state of stress in the strong layer of the upper crust is the combined effect of these two opposite stress systems together with bending and other local and regional stresses such as due to ridge push
模拟结果表明：由于均衡机制，造山带下部的低密度山根促使地壳隆升、造山，山根是地壳刚性层中张性构造应力的主要力源；与此相反，冷的高密度岩石圈向软流圈插入、拆离、下沉，从而形成岩石圈根，它引起挤压造山和岩石圈地幔物质的重新调整，也是地壳刚性层中挤压性构造应力的主要力源。 |
| 9. | Based on development platform and the software designing , we develop a self - governed and perfect database system for surface wave tomography in china and its adjacent land and sea areas . this database system is helpful and important for probing into the deep earth , the form and evolvement of lithosphere / asthenosphere , the form and evolvement and the relation of surface structure and deep structure of chinese continent
为对这些海量数据进行合理有效管理，作者采用发展较成熟的开发平台和软件设计方法，开发一个独立、功能完善的“中国及相邻陆域海域面波层析成像数据库系统” ，对研究地球深部过程，对了解中国及邻区边缘海岩石圈软流圈形成及演化，了解中国大陆形成及演化以及地表构造与深部结构的关系都具有极大帮助和重要的意义。 |
| 10. | Given their oib - type trace element pattern and depleted sr - nd isotop ic composition , the datong alkali basalts are interpreted to be generated within the asthenospheric mantle but at a shallow depth compared to the yangyuan alkali basalts . the datong tholeiitic basalts exhibit low snd values ( 1 - 4 ) . their sr - pb and nd - pb isotopic correlations are consistent with a mixing between the depleted mantle and emi - like component
大同地区第四纪时期同时产出碱性和拉斑玄武岩，碱性玄武岩也主要来自于软流圈地幔，岩浆起源深度小于阳原样品；拉斑玄武岩具有较低的nd ( nd = 1 - 4 ) ， pb - nd以及pb - sr同位素相关关系暗示其可能是dm和型富集地幔( emi )组分之间混合的结果，反映了软流圈和岩石圈地幔之间的相互作用，岩浆起源较浅。 |
