Our calculated results show that the relative stability of the isomers depends on the level of theory used: in the framework of DFT, Au10 trends to form planar structures, while the MP2 calculations show that the three-dimensional isomers are energetically more favorable. Based on the present results, Au10 may be conjecturably a critical species of gold clusters which bridges the planar structures and three-dimensional ones.

计算结果表明Au10团簇异构体的相对稳定性明显依赖所使用的理论方法和泛函，密度泛函结果显示Au10倾向于采用平面结构，且不同的泛函给出异构体的相对稳定性次序也不相同，而MP2计算则显示三维空间结构的Au10团簇更稳定， Au10可能是金团簇从二维结构到三维结构演化的一个临界点。

Object edges are grouped on the basis of their geometrical and connectional relationships.

1引言计算机视觉研究的一个主要任务就是从二维图象来描述三维景物，即图象中各物体的属性以及他们之间的相互关系。

Methods One normal adult male was choosed, and his left elbow joint performed in pronation and extention position was scanned by spinal CT, and the two-dimensional image was dealed with Mimics 1 0 software, the three-dimensional finite element model was built up by Abaqus 6.7 software. Finite element calculation was performed to simulate the impact of 1 000 N on the elbow joint, and the stress distribution in the radial head and coronoid were analyzed.

选取1名正常成年男性为研究对象，使其左肘关节处于旋前伸直位，行螺旋CT断层扫描，得到CT数据二维图像，采用Mimics 10.0软件系统处理，利用Abaqus 6.7建立肘关节三维有限元模型，模拟施加1000 N冲击载荷，分析冠状突及桡骨小头内应力分布情况。

This paper provides a new recognition algorithm based on the projective invariant, it can effectively recognize 3D objects from their 2D images and will not be affected by visual angles. It means that this algorithm can recognize deflective characters directly.

本文提出一种新方法——基于射影不变量的识别算法，正是不受视点的影响，可由任意视角的二维图像识别三维目标，即它可以不经过倾斜校正直接识别出歪斜变形的字符。

We derived cell populations with properties of ectodermal and mesenchymal cells in 2D culture and incorporated these divergent cell populations into 3D epithelial tissues.

我们利用二维培养将胚胎干细胞分化为具有外胚和间充质特性的细胞，再将这些细胞复合入三维上皮组织。

The results showed that the particle-electrodes had good electrocatalytic activity and stability for the degradation of phenol.

结果表明，该粒子电极对目标污染物苯酚显示了良好的电催化活性和稳定性，在相同反应条件下，不加粒子电极的二维电解时苯酚的降解率为55.6%，而三维电催化氧化过程中降解率为90.8%，大大提高了苯酚去除效果。

Concrete algorithm is firstly recognizing 2D feature obtained from geometric entities, then on the instruction of the shape analysis combining with the projective rulers of mechanical drawing, matching three 2D view features, creating 3D basic model, forming a operation list, finically finished 3D reconstruction.
