The cross section of the composite crystal was observed by optical microscope and scanning electron microscope ( SEM), the stress in bonding area was observed by micropolariscope; 在偏光显微镜下观察键合区域的应力,利用干涉条纹来表征复合晶体的光学均匀性;
For a plate strengthened reinforced concrete beam under different loading, plate length and width and different cross section, the solution can be used to check the maximum bonding shear stress to prevent the plate debonding in the beam at the cut off point of the plate. 采用这些公式可以对不同荷载作用、不同粘结长度和宽度及不同梁截面形式的贴片加固梁片材端部界面最大粘结剪应力进行验算,以防止加固梁片材端部出现界面剥离破坏。
Experimental gel, control gel were applied in the experimental group and control group, the cross section for broken bones broken bones fixed after bonding, respectively, and soaked in physiological saline test day, 1,2,3 weeks after the torque and torsion angle. Results: 1. 实验胶、对照胶分别涂抹于实验组及对照组断骨截面上进行断骨的粘接固定后,分别测试当天和浸泡于生理盐水1、2、3周后的扭矩和扭转角度并比较。
Cost of capital effects of cross listings are the core research field of cross-listings from the point of corporate finance. Market segmentation hypothesis, liquidity hypothesis, investor recognition hypothesis and bonding hypothesis are four important theories to interpret the cost of capital effects of cross-listings. 交叉上市的资本成本效应是从公司理财角度研究交叉上市的核心领域,市场分割假说、流动性假说、投资者认知假说和绑定假说是解释交叉上市资本成本效应的四个重要理论。
