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。

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。

There are gaps among the crystal structures. In order the micro_object to be a continuum, a close-packed Wigner-Seitz model is put forward by the object structure principle.

针对Hamaker理论在工程实际中存在的问题，从物质结构出发分析晶体结构，发现晶体结构存在空隙，Hamaker连续介质假设不成立。

The results that the chromatin structure in ANF gene region for 0.5 month-old rats are in loose form while it is in close-packed form for 6 month-rats.

本项研究发现并肯定了发育及老化过程中ANF基因表达规律，老化时染色质构象的变化是ANF基因表达衰退的重要原因，发现ANF基因中三个CCGG序列完全甲基化可能是该基因表达"关闭"的原因。

The results show that the most close-packed surface (111) orientation of FCC metals which have the lowest surface energies will grow preferentially, the surface energies for the all lattice surfaces increase linearly with increasing including angle between the surfaces and (111), which are consistent with the experimental and the linear muffin-tin-orbital-atomic-sphere-approximation results.

结果表明，FCC金属的密排面（111）的表面能最小，则该晶粒取向优先生长，与实验结果和第一原理的LMTO－ASA计算结果一致；各个晶面的表面能均随着其它晶面与（111）晶面的夹角的增长而呈线性增长关系，因此利用（111）面可推导出其他各面的表面能量。
