Slowing a wave changes its direction, a process called refraction.

放慢光波改变了其方向，这个过程被称为折射。

Those waves change weather and they change climate, and we are going to study how do they do that.

这些气流改变了天气变化，我们要对原因作出调查。

We also talked about pitch, and how the intensity of a sound wave changes with amplitude and distance.

我们还讨论了强度，以及强度如何变化 声波根据幅度和距离。

In these early stages, hyperacute T wave changes are followed by a very charecteristic ECG abnormality in the affected leads.

在这些早期阶段，受影响导联超急性T波改变后，会伴随着非常典型的ECG异常。

Any disturbance of these plates, such as the vibration induced by a sound wave, changes the capacitor's properties in a way that is easily detected.

平行板上的任何骚动，比如由声波引起的振动，都会改变电容器的属性，不过改变的方式很容易检测。

Experience the unique beauty of every season, as changes in Earth's atmosphere, daily and annually, can create pressure waves, changing the ionosphere's shape and density.

体验每个季节的独特之美，因为地球大气每天和每年的变化都会产生压力波，改变电离层的形状和密度。

In the minutes following a hyperacute T wave changes, the ST segments in leads overlying the myocardial region deprived of arterial blood supply begin to rise above the isoelectric line.

超急性T波改变后的几分钟内，心肌缺血区的导联ST段开始高于等位线。
