查询词典 subcontinental

The parental magma of the mafic dykes is probably derived from EMI, DM-PREMA and subcontinental mantle sources.

同位素和微量元素研究显示，岩浆源区主要与富集Ⅰ型地幔，弱亏损的常规地幔以及陆下岩石圈地幔有关。

In the process of intraplate convergence of continental lithosphere, parallel-layer detachment s commonly occur during the subduction of continental crust, owing to the multi-layer and multi-interface characteristics of the subcontinental lithosphere.

与洋陆俯冲关系不同，在板内汇聚过程中，大陆岩石圈固有的多圈层、多界面结构的特点，使得地块的俯冲变形伴有多圈层顺层拆离解耦的行为，使变形结构复杂化。

While we were trying to understand the origin of subcontinental mantle anisotropy by SKS splitting measurements in Qinghai-Xizang plateau, we were perplexed for answers to the following questions:(1) why the inefficient Sn propagation region correlates with the large delay time (1.91-2.40s) of SKS splitting,(2) why very strong δt variations occur at the edges of this region, and (3) what results in the abnormal delay time.

当人们试图解释青藏高原异常的剪切波分裂成因时，以下的问题让人们感到困惑：为什么异常大的SKS分裂延时(1.91-2.4s)出现在青藏高原北部Sn波缺失区；(2)为什么分裂延时突变（1.47s和1.09s）出现在Sn波缺失区的边缘；(3)为什么快波极化方向与地表大规模的构造走向之间存在约20°-30°的偏差。

Its main aims include:(1) understanding the magmatic processes of the volcanic rocks and their petrogeneses;(2) discussing the possible enrichment processes induced by subduction of continental slab;(3) providing geochemical constraints on the nature of lithosphere (including the subcontinental lithospheric mantle and lower crust) of the different tectonic units confined by the major faults across the belt; and (4) geochemical comparison of the lithosphere in an attempt to define the possible boundary between the North China and Yangtze Blocks during Mesozoic time.

中文摘要：项目开展了穿越苏鲁造山带南北向晚中生代火山岩及相关火成岩的廊带剖面(包括苏鲁带的胶东、青岛、滁州和下扬子地区的溧水盆地)的地球化学研究，理解各区块晚中生代岩浆作用过程和成因，探索大陆俯冲作用的地幔富集过程以认知各主要断裂围限地区的岩石圈性质；通过对比不同地区的岩石圈性质来限定苏鲁地区华北与扬子陆块的中生代碰撞边界。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
