查询词典 layer

Crystal lattice constants are close to other experiment results. Three kinds of chemical bonds exist among Mg and B atoms, between magnesium and boride is ionic bond and metallic bond is the predominant interaction in the layer formed by magnesium atoms. A strong covalent bond in the form of sp2 hybrid between boride atoms is the most important factors which can affect the transition temperature of MgB2. Population analysis clearly shows that electrons are transferred from Mg to B, as a result, the electron-phonon coupling in the layer of B is very strong.

规范保守赝势的计算结果表明，晶格常数与实验值误差在很小的范围内，分析了引起MgB2(001)面结构超导转变时电子浓度和偏态密度的变化情况，发现构成该超导体结构的成键有3种，着重从结构的电子浓度变化分析了其超导特性，六角蜂窝状结构中硼原子间相互作用为sp2杂化的共价键，镁原子和硼原子之间是离子键结合，镁原子层是金属键结合，镁原子的价电子部分转移到硼原子的pz轨道，部分电子为镁原子层共用。

The method of applying sidewall coring data to gas layer identification is discussed in this paper. It is found although Geo-chemical chromatogram and fluorescent microgram can not be taken as the direct basis to identify gas layers, they can provide proof for gas layer determination, and they can be as references for the work in the near future.

探讨了井壁取心分析资料辅助判断气层的方法，得出地化及荧光显微图像虽然不能作为判断气层的直接依据，但能够为判断气层提供佐证，在今后的工作中可以借鉴。

In this thesis, we transfer the microgroove patterns onto the Poly substrate to avoid the cracks by means of replica molding method. Different from traditional polymer alignment layers, the bendable materials serve not only as substrates but also as alignment layer; thus, we successfully fabricated the flexible alignment-layer free twisted nematic liquid crystal cell.

在本研究中，我们使用复制成形法，直接将奈米沟槽转印到软性高分子基板上，来改进脆裂的问题，不同以往的高分子薄膜，我们是让基板本身就具有配向液晶分子的功能，做出不需额外配向层的可挠式扭转向列型液晶元件。

As much of a giggle to stitch as it is to give, this newest design by Nora Corbett for Mirabilia is an ode to those euphoric winter days when children dress themselves in layer upon crazy-quilt layer, pull on mommy-made mittens and scarves, and flaunt collars and cuffs embroidered by doting aunts and grandmas.

就像它给予的那样多的欢笑，这幅最新的Nora Corbett为Mirabilia所做的设计是一首赞扬快乐冬日的颂歌。在那些快乐的冬日，孩子们穿着一层层的衣服，戴着妈妈做的手套和领带，然后夸耀着疼爱自己的婶婶和奶奶为自己绣了花的衣领和袖口。

Advanced step-water heating layer by layer settles successfully problem of mixing of boiled and unboiled water of traditional single tank heater*and at the same time gets rid of huge body, low-efficient heating, water-leaking, non-heating, unboiled water mixing of multi-tank heater.

先进的步进逐层加热技术有效解决了冷热水混合问题，避免了传统单箱式开水器生水混入的问题和多箱式开水器体积庞大、加热效率不高、浮球阀控制不可靠造成的漏水、不加热、生水混入等难题。
