It took 17 minutes to unfold its solar panels and send a signal back to earth.

这款探测器花了17分钟打开太阳能电池板并向地球发送了信号。

If our spacecraft send back signals, charged particles from the sun could interfere, causing gaps in the data that reach us.

如果我们的宇宙飞船发回信号，来自太阳的带电粒子可能会干扰，导致到达我们的数据出现空白。

Rodney slid his right foot back, signaling that he would go in for the ball. He kept his eyes fixed on the referee.

罗德尼将右脚向后滑动，暗示着他将要去争球，他将眼睛盯紧裁判员。

That ground station then relays those signals back to the satellite, which then relays them back to you and your user terminal.

该地面站然后将这些信号中继回卫星，然后卫星再将它们中继回您和您的用户终端。

The network sends a signal to the spacecraft, which then sends a signal back to DSN ground stations in Australia, Spain and the United States.

该网络向航天器发送信号，航天器再将信号传回澳大利亚、西班牙和美国的深空网络地面站。

The corresponding waves will travel down the tube, in order, and a little while later, hit the microphone, which converts the signal back into 1's and 0's.

相应的波将按顺序沿着管子传播， 稍后到达麦克风，麦克风将信号转换回 1 和 0。

Today you learned how electrical synapses use ion currents over gap junctions to transmit neurological signals, and how chemical synapses turn electrical signals into chemical ones, using neurotransmitters, before converting them to back electrical signals again.

今天你学习了电突触如何利用缝隙连接上的离子流来传递神经信号，以及化学突触在将它们再次转换为电信号之前是如何利用神经递质将电信号转化为化学信号的。

When we tap your, let's say your patellar tendon that causes a stretch in a muscle spindle, this sends a signal back to the sensory neuron, which activates a motor neuron in the spinal cord to cause your knee to kick up.

当我们敲击你的，比方说你的髌骨腱，它会导致肌肉纺锤体的拉伸，这会向感觉神经元发送信号，这会激活脊髓中的运动神经元，使你的膝盖抬起。
