So the study on tertiary dendrite growth will be great value both in theory and in engineering.

因此，研究三次枝晶的形成规律和物理冶金，无论是在理论上还是在工程上都具有重要的价值。

Fractal dimension can be used to describe the morphology of tertiary dendrite.

Through calculating it is discovered that there is elastic strain energy concentration near triple junction when loading direction is parallel with triple junction, but the concentration degree is not so high.

因为应变能中包含了所有的应力分量和应变分量，能全面地反映各应力分量对三晶交点应力集中程度的影响。

It is also found that if the monatomic model of Johnson is used the pair potential constructed by the former method can give correct heats of solution.

发现如果采用第三章的模型作为单种原子的埋入原子法模型，则由前者构造的合金对势V〓不能给出正确的溶解热，而由后者构造的合金对势V〓却能给出基本正确的超结构的晶格常数、体模量和结合能。

The main contents of the thesis are summarized as followed:(1) The nucleation and growth mechanism of 3-D flowerlike ZnO crystals in ZnCl2-NaOH system was investigated through monitoring the crystal structure, morphology, and Zn concentration in reaction solution and at regular intervals.

本论文的主要内容包括：(1)三维花状ZnO微晶的生长机理研究以ZnCl2-NaOH为体系，通过跟踪反应过程中不同时间溶液中Zn浓度以及产物的物相和形貌，揭示了3-D花状ZnO晶体在液相反应中的成核、生长机理。

On the rhombohedron face {1011}, Dauphine twinning showed different shapes of etching pits between individuals, because rhombohedron positive form {1011} and negative form {0111} appeared on both sides of twin partition line, while Brazil twinning showed symmetry plane between the irregular triangle etching pits of individuals. On the trigonal prism section 11(average20, Dauphine twinning showed different shapes of etching pits between individuals, because trigonal prism positive form {1120} and negative form {2110} appeared on both sides of twin partition line, while Brazil twinning should show symmetry plane between the ellipse or quadrilateral etching pits of individuals, which was not observed.

菱面体{1010}面上存在道芬双晶处，道芬双晶双晶缝合线两端分别是菱面体正形、菱面体负形出露处，导致蚀坑形状不同；菱面体{1011}面上存在巴西双晶处，不规则三角形蚀坑形态的方位关系为对称面关系；三方柱切面{1120}面上存在道芬双晶处，道芬双晶双晶缝合线两端分别是三方柱正形、三方柱负形出露处，导致蚀坑形状不同；三方柱切面{1120}面上存在巴西双晶处，椭圆形或四边形蚀坑方位应为对称面关系，但实验中未见到。

The third chapter investigated the elasticity problem of one dimensional trigonal QCs.

第三章研究了一维三方准晶的弹性问题。

Cubanite is antiferromagnetic and the crystal is actually a trilling.

方黄铜矿石一种反铁磁性的矿物，晶体实际上是三晶。

A systematic analysis of the icosahedral hierarchic structure in the 3D icosahedral quasicrystal and its approximants have been made. There is an icosahedron at the center surrounded by 12 icosahedra. If two neighboring icosahedra are vertex-sharing, the multi-shell Mackay cluster consisting of 127 atoms will form. If two neighboring icosahedra penetrate into each other, the multi-shell Samson-Bergman-Pauling cluster consisting of 137 atoms will form.

系统地分析了三维二十面体准晶的近似晶体相中具有二十面体对称的等级结构，中心1个二十面体，周边12个二十面体，如两个相邻二十面体共顶点连接，得出的是由127个原子构成的Mackay球形原子簇；如两个二十面体互相穿插，得出的是由137个原子构成的Samson-Bergman-Pauling球形原子簇。

THREE-ROOM FOUR SEASONS WAFER SIZE RELATIVE TO THE EXPLICIT WASTED.

三房的面积相对于四季晶园就显的浪费了。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
