three-beam

The low cycle reciprocating load experiment gives a good opportunity to study the seismic behavior of three kinds of T-shaped concrete steel tubular composite column and steel beam connected node.

通过低周往复荷载作用下的拟静力试验，对9个T形钢管混凝土组合柱-钢梁连接节点试件的抗震性能进行了研究。

In order to study controlling beam by beam, we studied the case of the two beams and three beams interaction by the next step.

之后，为了研究光束对光束的控制作用我们模拟了两光束和三光束相互作用情况。

The system comprises the collimator with three optical fibers, the beam deflector and the reflector.

该方法与系统包括一个三光纤准直器, 一个光束偏转器与一个反射器.

Studying two-beam coupling, we get the gain curve of the signal beam in three cut planes in BSO when the polarization of signal and reference beams are parallel or not parallel.

对二波耦合，分别讨论了在三种BSO晶体切面上，信号光和参考光的偏振态互相平行和存在夹角时信号光增益特性；
