查询词典 basaltic layer

The effects of electroplated Ni layer and electroless plated Ni-P layer on the diffusion behavior in Sn-Ag/Cu solder joint were studied. The results by EPMA analysis showed that the electroless plated Ni-P layer acted as a good diffusion barrier between Sn-Ag solder and Cu substrate. However, the electroplated Ni layer can not hinder the inter-diffusion and reaction between molten Sn-Ag solder and Cu substrate when reflowing, and there was a layer of IMC (Cu6Sn5) at interface of Sn-Ag/C u solder joint.

摘 要：研究了电镀Ni层和化学镀Ni-P合金层对Sn-Ag/Cu焊点扩散行为的影响，电子探针分析表明：化学镀Ni-P合金层能很好地阻止Sn-Ag/Cu焊点在焊接过程中的Cu，Sn互扩散和相互反应；而电镀Ni层则不能阻止Sn-Ag/Cu焊点在焊接过程中的Cu，Sn互扩散和相互反应，界面反应产物仍以Cu6Sn5为主。

On the basis of an integrated analysis of the geochemical features of these volcanic rock associations,this paper concludes that thebasalts originated mainly from interaction between mantle-derived magma and low-crustal materials, and rhyolitic volcanic rocks resulted from thermal and chemical interaction between basaltic magma and the upper part of crustal materials.Basalts and rhyolites in different cycles have different source regions,and they are products of multiperiodic pulsive layer partial melting.

根据对火山岩地球化学特征的综合分析表明，玄武岩主要为幔源岩浆与下部地壳岩石相互作用的产物，而流纹岩则为玄武岩浆与上部地壳物质进行热及成分交换的结果，不同旋回的玄武岩和流纹岩有不同的源区，为多次脉动分层部分熔融的产物。

The Middle Devonian Beitashan Formation consists of a series of intermediate-basic volcanic rocks intercalated with more than 100 m thick picritic layer at the bottom, whereas the Middle Devonian Yundukala Fm. is composed of a series of shallow-sea fine-clastic rocks interbedded intermediate rocks and intermediate-basic rocks. The Late Devonian Jiangzierkuduke Fm. includes pyroclastic rocks intercalated with intermediate-basic and intermediate-acid rocks, whereas the Late Carboniferous Batamayineishan Fm. consists chiefly of basalts and basaltic andesites intercalated with tuff, siltstone and carbonaceous shale.

Don Quixote is a funny and sorrow story, a work that makes readers taste deeply sorrow when they are laughing at scenario of story. This text divides the meaning of Don Quixote into three layers. The first layer is taste layer, to analyse the comedy of absurdness and the tragedy of sublimity in Don Quixote. The second layer is history layer, to analyse that Don Quixote reflects the

本文把《堂吉诃德》的意蕴分为三个大层次，第一层是审美情韵层，主要分析了《堂吉诃德》荒诞的喜剧美和崇高的悲剧美；第二层是历史内容层，结合塞万提斯本人的经历和西班牙当时的历史，分五个层次进行阐析——塞万提斯本人的真实映射、西班牙社会的真实写照、摩尔人被驱逐的血泪史、西班牙海外殖民历史的曲折反映、反映了西班牙人文主义者与农民的社会关系等；第三层是哲理意味层，剖析了堂吉诃德的疯癫中显示的生命真实，从中看到知识分子"知其而不可为而为之"的人生态度，也映射出的塞万提斯的人文主义思想及其信仰危机和他心中的宗教理想，表现了作为文艺复兴后期代表的塞万提斯的进步的人文主义思想，蕴涵着作者心中无法磨灭的宗教理想，寄托了塞万提斯心中的爱憎和理想。

The results indicated that the ice sample was obviously divided into four layers as micro-pollution layer,cleaned layer,mixed layer and precipitate layer after aqueous bromamine acid solution was completely frozen.

试验表明，溴氨酸水溶液完全冻结后，冰样可分为4层：微污染层、洁净层、混合层和析出层。

The third collector layer has a higher doping concentration than the second collector layer in such a way as to be located between or sandwiched by the first collector layer and the second collector layer.

第三集电极层具有比第二集电极层高的掺杂浓度，被第一集电极层和第二集电极层夹在当中。

The species diversity of stratum layer, shrub layer and forest community was each higher but that of herbage layer and bine layer each lower than that in control.

乔木层和灌木层的植物种多样性较大，群落植物种多样性较高，但草本层和藤本层的多样性比纯林低。

The results of the test show that the whole intensity and comprehensive stability of subgrade made a good progress because the capillary water cant rise by using the insulating layer. In the prior condition of taking insulating layer thickness as 0.2m, choosing insulating layer 0.5m, 0.8m, below the pavement, the stability of seasonal frozen soil subgrade is analyzed. The results of the test also show that the optimal position of the insulating layer is 1.0m～1.5m .

试验表明，由于隔离层的作用使得毛细水无法迁移，对路基整体的强度和综合稳定性都有了很大程度上的提高，同时试验还表明在隔离层厚度为0.2m的前提下，设置在距路面以下1.0m～1.5m位置，即路基表面以下0.5m～0.8m处对路基的稳定性最为有利。

In the case of read-only CDs, the substrate lies directly next to the reflection layer. In the case of a CD-WO, an absorption layer existsbetween the substrate and the reflection layer. This layer can be irreversibly modified through strong thermal influence, which changes the reflection properties of the laser beams.

就只读CD来说，亚层应紧接在反射层之下，而CD-WO中，在亚层和反射层之间还有一个吸收层，这一层在强热的作用下做不可逆修改，因而改变了激光束的反射特点。
