The motion of the wave through the molecular structure. I've been looking at it all wrong.

过分子结构的波状运动 我之前一直想错了。

This sudden release of energy creates different kinds of waves that cause the ground to move.

这样突然释放的成了不同的波状运动，会造成地面移动。

Their undulating flight, the grace of their aerial curves, and the play of their colors allured and delighted the eye.

它们的波状起伏的飞行，它们在空中的优美曲线，它们鲜艳夺目的色泽，吸引了和迷惑了人们的眼睛。

From a tiny sphere, to electron orbits, to energy levels and then to the electrons being wave-like charge distributions.

从微小的球体， 到电子轨道，到级， 再到电子的波状电荷分布。

I would say ideal state, it would be great if there was something that was just a bit more contoured to support the head.

我想说的是理想状态，如果有什么稍微有一点波状外的东西来支撑头部，那就太好了。

Together, they perform what's called peristalsis, which is a series of coordinated wave-like muscle contractions that helps squeeze the food bolus in one direction.

内环肌与外纵肌的活动共同成了肠道的蠕动；肠蠕动就是指一系列协同进行的平滑肌的波状收缩，可以挤压食团，确保食物向前移动。

What happens is that the normal wave-like contractions of the intestine, called peristalsis, grab this leading edge and pull it into the part of the bowel ahead of it.

情况下，肠管的波状收缩运动，即肠蠕动，会把套叠前缘送入远端肠腔中。

According to the authors, asperitas clouds are  defined by their rough, somewhat wavelike cloud base, that lacks the smooth undulating shape of  the (possibly related) undulatus cloud type.

根据作者的说法，阿斯佩里塔斯云是由其粗糙的、有点波状的云底来定义的，它缺乏（可相关的）波状云类型的光滑起伏状。

Yeobright searched his desk, and taking out a sheet of tissue-paper unfolded from it two or three undulating locks of raven hair, which fell over the paper like black streams.

约布赖特在书桌里翻找了一会儿，拿出一个绵纸小包，打开来，里面是几绺波状弯曲的乌亮黑发，像是黑色小溪落在纸上。

These aren't smooth and wavelike, like the undulatus cloud type we just looked at, but have  a formation that is chaotic, like the stormy ocean we talked about earlier.

这些云并不像我们刚刚看到的波状云那样光滑且呈波浪状，而是具有混乱的态，就像我们之前讨论过的波涛汹涌的海洋。

But for the first heartbeats the researchers found no clear pacemakers; different embryos had different cells that started beating first and they triggered the cells around them in a wave-like pattern.

但对于第一次心跳， 研究人员没有发现明显的起搏器；不同的胚胎有不同的细胞， 它们首先开始跳动， 并以波状模式触发周围的细胞。
