In high seismic intensity zone, when the spans of adjacent frame beams have great difference, the short-span frame beam can be designed as coupling beam.

在高烈度地震区，相邻框架梁跨度相差过大时，可以将短跨框架梁按照连梁设计。

But a laser at a slightly different wavelength, called a coupling beam, can alter the quantum properties of the atoms so they no longer absorb that wavelength.

但一束波长稍稍不同的激光(被称为耦合光束)可把原子的量子性质改变得使原子不能再吸收该波长。

Second, under the rare case of earthquake, at first coupling beam arrive into the plastic point and dissipate the earthquake input energy to insure the security of the main structure of wall.

二是罕遇地震下，连梁先于墙肢进入塑性，耗散地震输入能量，保护剪力墙主体结构的安全。
