The Lorentz transfer of time coordinates is the sum of two times, one related to time expansion and the other to the relativity of photon's flight time from the radiant to the receiver.

证明了时间坐标的洛伦兹变换是两个时间的和：一个与时间膨胀有关，另一个与光子从光源到接收器的飞行时间的相对性有关。

They also were a time of expansion into new territory.

It's constant pressure. OK, so now, last time you looked at the Joule expansion to teach you how to relate derivatives like du/dV.

这是恒压的，好，上节课你们,学习了焦耳定律,以及怎样进行导数间的变换。

OK, so we ended up last time, we talked about Joule-Thomson expansion, which is an irreversible expansion through a nozzle, through a porous plug, constant enthalpy expansion.

上节课，我们讨论了焦耳-汤姆逊，膨胀过程,也就是气体，通过毛细管。

"Usually, bat sounds are inaudible to humans as they are too high for us to hear but special 'time expansion' ultrasonic detectors convert these sounds to a lower frequency, " Prof Jones, who is also chairwoman of the UK Bat Conservation Trust, explained.

"It is no longer a time for expansion but for efficient use of existing resources, " says Sasaki Katsumi, director general for policy and information at the metropolitan government.

Even though the markets' tell tales are imperfect, they could be used to empower the regulator, which brings me to the second major obstacle to dynamic oversight: political opposition during the time of expansion.
