分类 根据骨在体内的部位，可分为颅骨、躯干骨和四肢骨三大类，其中躯干骨和颅骨统称为中轴骨。

Both crystallographically unique Zn atoms exit as an octahedral geometry. The four equatorial positions of Zn1 atom are occupied by the carboxylate-oxygen atoms of the two tartrates, and the two oxygens of the left four carboxylate-oxygen atoms coordinate to two different Zn2 atoms, respectively, forming infinite coordination polymer chains. The left two of the trans equatorial positions of Zn2 atom are completed with two oxygen atoms of two water molecules. The axial positions of both Zn atoms are occupied by the nitrogen atoms from different 4,4'-bipyridine molecules to give a 2D rectangular-grid layers with a cavity dimension of 0.51165(3)nm×1.13896(5) nm. A three dimensional network is formed by the crystallization water chains joined by the carboxylate-oxygen atoms through hydrogen-bonding interactions.

两个晶体学独立的Zn原子均为八面体构型，其中Zn1原子赤道配位点被2个酒石酸根中的4个羧酸根氧螯合配位， 2个酒石酸根中剩下的4个羧酸根氧中的2个分别与2个Zn2原子连接形成无限一维链， Zn2原子的另外2个反式赤道配位点被2个水分子氧占据，同时这两种Zn原子的轴向配位点均被4，4'-联吡啶的氮原子占据，形成具有矩形格子[0.51165(3) nm×1.13896(5) nm]的二维层状结构，游离的2个水分子通过氢键作用形成二聚体，并与酒石酸根中未与Zn配位的羧酸氧连接，把二维层状结构连接成三维网状的超分子结构。

Aimed at all kinds of damage phenomena in the sleeve usage of oil-film bearing in the backup roll of Baoshan 1580 hot strip mill,during the process of elastic conjunction between sleeve and rollneck,deformation and load properties are quantitatively analyzed by boundary element method for 3D elastic and plastic contact problems.

针对宝钢1580热连轧机精轧机组支承辊油膜轴承锥套使用中存在的各类损伤问题，利用三维弹塑性接触问题边界元法定量分析了轧机油膜轴承锥套与轧辊辊颈过盈装配过程中的变形和载荷特性，得出了装拆过程中不同的胀型压力和轴向推力条件下锥套接触压力延母线方向的变化规律，同时锥套端部和密封槽附近接触压力峰值的存在是加速锥套损伤及降低其使用寿命的重要原因。

Dian floor of the distribution of symmetry in the changes, scattered in the contact and tortuous loop, the actual situation of health, Xiaoqiaolinglong, space rich, varied levels, see in the small, unknowingly for such a small place, is compact and Cuola dependencies, and its layout Pingchuan temple is different from the axis prominent, symmetrical, but also different from the mountain Temple mountain gradually increase the pattern, Junyi cliffs convex, the shape of the potential trial,by zhe naturally , air and structure, look, Stack Cuola, subtle changes to the composition and physical space to contrast the orderly performance art.

殿楼的分布都对称中有变化，分散中有联络，曲折回环，虚实相生，小巧玲珑，空间丰富，层次多变，小中见大，不觉为弹丸之地，布局紧凑，错落相依，其布局既不同于平川寺院的中轴突出，左右对称，也不同于山地宫观依山势逐步升高的格局，均依崖壁凹凸，审形度势，顺其自然，凌空而构，看上去，层叠错落，变化微妙，使形体的组合和空间对比达到了井然有序的艺术效果。
