The behavior of post-tensioned steel beam-to-CFT column connections with energy dissipating bars has been investigated analytically and experimentally. Experimental results demonstrated that the connections possess self-centering capability, gap opening and closing at the beam-to-column interface, energy dissipation characteristics, and no inelastic or residual deformation. Moreover, analytical predictions correlated well with the experimental results.

而如果我们的心在焦虑，苦恼的，或在生气和喧哗中，同一个天线，以一个敏感的植物在日落后闭合了花瓣那样类似的方式，被混乱失序取代，到最初源头高频率辐射的那些精细的连接被关闭和缩小了。

Over-temperature is detected by a normally-closed switches connected in series and embedded in the motor stator windings.

过热现象是通过并联或内置在电机定子绕组的正常闭合开关来进行监测的。

In this thesis, soft starter equipment realized by thyristors power transform circuit is studied. To improve equipment performance, we apply variable reactance technique to AC motor soft starter study. The high voltage AC working winding of reactance is in series with motor winding, while low voltage control winding and thyristors groupware with intelligent controller constitute close loop circuit. We adopt thyristor phase control voltage-regulator mode to control low voltage winding, then control the reactance of high voltage winding, and then arrive at the goal-control the current and voltage of motor AC to realize motor soft starting.
