搭接

The bond behavior between FRP sheet with FRP shear key and concrete was studied by experiment on a single shear test setup. Test invariables including the height, the width and the length of shear key, appending coarse-sand-coating and concrete compressive strength were considered.

采用FRP板－混凝土块搭接接头的单剪试验方法，考虑剪力键高度、宽度和长度、附加砂粒增强以及混凝土强度等因素，对带剪力键的FRP板与混凝土间粘结性能进行了深入研究。

When the elastic modulus is high, stress and strain are mainly concentrated at edge of the overlap region, while those in weld spot zone are relatively even; when the elastic modulus is low, stresses in the adhesive layer are small while stresses are concentrated to a certain extent at edge of the weld spot.

分析发现，胶粘剂弹性模量对接头中应力应变分布的趋势有明显影响，胶粘剂弹性模量高时，搭接区边缘附近区域应力应变高，焊点区应力应变值相对较小；弹性模量低时，焊点边缘处存在一定的应力集中，胶层中应力较小。

The results show that obvious shearing deformation is found on the lap solder after 4 thermal cycles, then is the visible displacement on the upper and lower surfaces.

结果表明，经过4个温度循环周期后，SnAgCu-CNT 搭接焊点发生了明显的剪切变形，产生了显著的上下表面相对位移。

Pin the lapped edge to the right side along the seam line and stitch close to the fold.

沿着缝线用大头针将搭接的边别在正面，然后紧造折边缉缝。

The minimum lap length of tension steel bar for earthquake proofing is L%%142lE%%143=ζ La.

抗震设计受拉钢筋的最小搭接长度L%%142lE%%143=ζ La 。

The influence of the distance between weld spots on static strength was studied by FEM in this paper.

通过对多点焊搭接构件的有限元分析，探讨了焊点间距对强度的影响，并与已有的实验结果比较，能较好的对应。

However because of its difficult lapping, it is easy for a leak to be produced when there are skylights, fans and clearstory etc, at the roof of a building.

但是由于其横向搭接困难，故当建筑屋顶有天窗、风机、气楼等突起构造以及需要与采光带等不同材料组合时，容易产生渗漏。

Adopting multiplexing technique and making use of communication line between CSC and CS to achieve simultaneous transmission of ISDN signal and electric power. According to the variation of circuit equivalent resistance to design detection circuit, which can judge that the line is short circuit or open circuit and the commercial power is working normally or failure. When the reserve power supply is working, the system judges its operation status by voltage and current detection circuit. Making use of the characteristic of the gas discharge tube to achieve suspension system detection of power line touching. Transmitting information collected up to PC by RS485 for the purpose of centralized monitoring.

采用复用技术，利用基站控制器和基站间的通信线路实现ISDN信号和电力的共同传输；根据线路等效电阻的变化设计探测电路，来判断开路、短路、市电供电、市电停电等情况；在后备电源工作时，通过电压、电流采样电路判断电源的运行情况；利用气体放电管的特性实现悬浮系统动力线搭接的检测；采用RS-485通信方式将采集到的现场信息上传以实现集中监控。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
