砌块

They are:In the third chapter, the crystal structures of these new dca complexes are described anddiscussed in detail. Besides two mononuclear complexes, 1 and 2, complexes 3～15 arecoordination polymer with novel and interesting structural characteristics. 3, 6, 7, 8, 9 are 1Dpolymers, 4 and 5 are of 2D extending structure, while 10, 11, 12, 13, 14, 15, 16, 17 form thefirstly reported series heteronuclear dca coordination polymer, in which (except 10) differentbuilding blocks, with different metal ions in them, construct interesting architecture, like α-and β-type 〓 chains, ladder chain 〓, scaffold structure of 12, and "sandwich"layer structure in 15 and 16, etc..

这些配合物是：第三章中，我们详细描述讨论了这些新型的二氰胺配合物的晶体结构，除两个单核配合物1和2之外，其余十五个为配位聚合物并具有新颖和有趣的结构特征。3，6，7，8，9是一维配位聚合物，4和5则呈现二维扩展结构，而10，11，12，13，14，15，16，17属于首次报道的一系列的二氰胺异金属配位聚合物，其中(除10外)含有不同金属离子的构造&砌块&可构建出有趣的结构，如α-和β-型〓链，梯形链〓，12中的脚手架结构，以及15和16中的&三明治&层状结构等。

Such as thin lightweight precast concrete blocks, hollow clay blocks and timber studding covered with either plasterboard, fibreboard, matchboarding, plywood, chipboard, resin bonded blockboard or other form of cladding.

如用轻薄混凝土砌块、空心砖、细木条再覆以壁纸板、纤维板、假型板、胶合板、经纤化处理后的废纸板、松脂粘合板或各种类型的复合材料板等。

The aircraft is also Mian Shaozhuan production of cement block and the best equipment.

该机也是生产免烧砖和水泥砌块的最佳设备。

Joint together by mortises and tenons , various inner partition and nonbearing walls can be provided in a modular way .

模卡式拼装节能墙体采用条形榫卯砌块拼装式施工方法，可以拼装成各种尺寸的内隔墙和非承重墙。

The result is that temperature distributing is along thickness direction and nonlinear, temperature stress distributing is symmetry about lengthways axis of the wall, and the temperature stress in the corner of the windows and osculant part between the wall and the beam or the pillar is bigger than the other part.

结果显示混凝土砌块整体建筑的温度是沿墙体厚度方向分布的；温度应力的分布是关于墙体纵向对称轴对称的，在洞口端角处以及圈梁、构造柱与墙体的接触处温度应力相对较大。

In this paper, a new structure system, the highrise lightweighted wall pannel frame made of coal ash in the main, was put forward.

提出了以粉煤灰砌块等工业废料为主要原材料的高层轻板框架体系。

To meet the needs for improving the wall and protecting the cultivated land, a new structure system, the highrise lightweighted wall pannel frame made of coal ash in the main, was put forward.

本文适应墙体改革及保护耕地的需要，提出了以粉煤灰砌块等工业废料为主要原材料的高层轻板框架结构体系，进行了1／3比例模型的房屋结构试验，对其在地震作用下的受力及变形特点进行了分析，研究表明这种结构具有较好的抗震能力，可以实现地震能量的分阶段释放

Addition of metallated terminal alkynes to carbonyls is considered as an effective route for the synthesis of chiral propargyl alcohols and has gained considerable significance in recent years.

末端炔对羰基化合物的不对称加成反应是构建手性炔丙醇的重要方法之一，其产生的光学活性炔丙醇是很多天然产物，精细化学品及药物分子的重要合成砌块。

From the starting material: propargyl alcohol, the building block was prepared easily by Jones oxidation, esterfication, bromination and selective trifluoromethylation.

第一部分：从丙炔醇出发，经过Jones氧化，甲酯化，顺式二溴化，再选择性地在酯基的β位实现三氟甲基化，合成了目标含氟砌块。

The pseudo-static test which subjects to horizontal load on the A-type autoclaved aerated concrete block wall was adopted. Reinforced concrete beams were set up at the upper and lower ends of the test block, and the four-bar linkage device was provided to ensure that the top of the wall was only in translatory motion, not in rotation at the level force. Hydraulic synchronous loading device was adopted to simulate the vertical load which was produced by the wall of the housing interlayer.

对A类蒸压加气混凝土砌块墙体采用水平荷载作用下的伪静力试验，试件的上下两端设置了钢筋混凝土梁，通过四连杆装置保证墙体顶部在水平力作用下只有平动而无转动，并采用同步液压加载装置模拟房屋层间墙体作用的竖向荷载。
