Shape memory alloy wires can increase the critical temperature of the beam, and also can restrain thermal buckling occurring or make the post-buckled beam back to initial equilibrium states.───形状记忆合金丝还能提高梁的热屈曲临界温度，抑制梁热屈曲的发生或使已发生热屈曲的梁回复到原来的平衡状态。

that case, CERN would adjust the strength of compensating magnets to coax the beam back into shape.───这种情形，CERN将调整补偿磁铁的强度以诱使粒子束重新回到平面上。

A second possibility, for more power-hungry devices, is to fire a finely focused infrared laser beam at a photovoltaic cell, which converts the beam back to electrical energy.───第二种可能性则能应用在更加耗电的设备上。其原理是发射一道精确聚焦的红外激光线，击中光伏电池，由此能够将光束转换回电能。

He says the spacecraft will begin beam back more detailed imagery and data within the next day or two.───他还说，飞船今明两天将会传回更详细的影像和数据。

The results they beam back are portraying our nearest star, and its influence on Earth, in a new light.───这颗离我们最近的恒星以及它对地球影响，所有的观测结果都被完整地记录并发送回来。

Now, try to place your speaker at the other side of your room and see how long it takes to get the beam back to the target!───现在，试着把你的演讲者的另一边，你的房间，就会知道需要多久来得到传回来的对象！

In that case, CERN would adjust the strength of compensating magnets to coax the beam back into shape.───遇到这种情形，CERN将调整补偿磁铁的强度以诱使粒子束重新回到平面上。

It will beam back more information than all previous Mars missions combined at a rate 10 times faster the older craft.───它的信息传输要比以往所有火星探测器总合高10倍。

A second possibility, for more power-hungry devices, is to fire a finely focused infrared laser beam at a photovoltaic cell, which converts the beam back to electrical energy.

I would beam back in a quietly idiotic manner.

The power generated on the Moon is then transmitted by microwave beam back to Earth.
