查询词典 closely packed

However, magnesium alloys have poor formability due to the hexagonal close-packed crystal structure.

但是，镁合金大多具有密排六方结构，传统上一直被认为是一种难以塑性变形、压力加工成形性能差的金属材料。

However, magnesium alloyshave poor formability and limited ductility at room temperature ascribed totheir hexagonal close-packed crystal structure.

目前热处理细化晶粒成为提高镁合金塑性的一种有效手段，但是研究工作多集中在铸造态镁合金，关于挤压态镁合金型材的研究很少。

According to the crystal structure of the n=1, 2 and 5 compounds, the structural principle of this family was proposed, which is based on alternate stacking of close-packed arrays and graphite-like sheets.

n=2和5化合物中的La也可以部分被其它稀土离子所取代，但相对于n=1化合物而言要困难一些，其中的La只能部分被取代，即使Nd和Sm也不能完全取代形成这两种结构类型的化合物。

The fcc structure is a close-packed structure, and the bcc structure is not, which explains why the volume of the iron decreases when this transformation occurs.

由于面心立方结构是一种密堆垛结构，而体心立方则较松散，这解释了铁在加热过912℃后体积减小的现象。

When adsorbed onto a mica surface, it can form close-packed globule-like interface micelles.

我们发现含有偶氮苯介晶基团的双头双亲分子azo-11在云母界面和表面上都可以形成具有很好取向的10nm宽的纳米条带。

But magnesium alloy has a hexagonal close-packed crystal structure with limited number of operative slip systems at room temperature, so magnesium alloys are normally low formability near the room temperature, and limits the expansion of magnesium alloy applications.

但是由于镁合金是密排六方结构，可开动的滑移系比面心立方和体心立方金属的少，使得镁合金的室温塑性较低，降低了成形能力，限制了变形镁合金的推广应用。

Moreover,Al_2Er phase is face centered cubic structure,which is different with the structure of Mg(Hexagonal Close-Packed).

但是过量的Zr将与合金中的Al反应生成Al_3Zr沉淀相，消耗了合金中的Al元素，减弱了Al对镁合金的细化、强化作用，而且由于Al_3Zr与镁基体没有共格关系，不能起到细化晶粒的作用，合金组织粗化。

It shall be stored in the cool (under 250C), well-ventilated dry place, close-packed without being mixed with acid and alkaline materials.

储存在阴凉(25℃以下)、通风干燥处，并确保包装严密，不能混入酸、碱物质。

The sample of close-packed opal-based photonic crystal with a PMMA microspheres' matrix have been prepared by self-organizarion .

本文利用自组装法制备了PMMA蛋白石结构的光子晶体，以及向其中填充TiO_2 使之形成反蛋白石结构。

Because this non-template method is based on the selective transfer of a single layer of close-packed microspheres from the colloidal crystal film to the PDMS stamp surface, it is possible to realize fine control over the microstructures of colloidal crystal film using a layer-by-layer lift-up process.

这一方法摈弃了传统的模板技术，采用PDMS为印章，在每个揭起过程中选择性地把一个单层的紧密堆积的微球从胶体晶体膜层揭走，通过layer-by-layer的揭起过程，实现了对胶体晶体膜的微观结构的精确控制。

It was just a normal day of school

那只是上学的普通一天

Which is a very good reference in this issue.

这是一个在这个问题上很好的参考。
