Finally, any downward deflection after the R wave is called the S wave.

最后，R波之后的任何向下的偏转波都叫S波。

After P and S waves come surface waves, which follow body waves and cause the most damage.

继 P 波和 S 波之后是面波，它紧随体波之后，并造成最大的破坏。

When an ectopic focus originates in the right ventricle, and then moves towards the left ventricle, the V1 lead shows a large negative complex, with a dominating S wave.

当异位起搏点起源于右心室，并向左心室传导，V1导联出现一个带主导地位S波的大型负相复合波。

S wave represents the last phase of ventricular depolarization at the base of the heart.

S波代表心脏底部心室去极化的最后阶段。

Lead V1 gives a characteristic M shape with a terminal R wave, while V6 sees a broader S wave.

V1导联呈特征性M形，其末端是R波，而V6导联可见更宽的S波。

In contrast, if infarction occurs under leads in which the QRS complex ends with an S wave, the S wave may disappear.

相反，如果梗死发生在QRS波以S波结束的导联下，S波可能消失。

And researchers found that P waves travel through both liquids and solids, while S waves travel only through solid matter.

同时研究人员发现P波能穿行液体和固体两种，而s波只能穿行固体物质。

Non-progression or poor progression of R wave - R wave stays low and S wave remains deep throughout all chest leads.

R波无进展或进展不良-所有胸导联R波持续较低，S波仍较深。

You see, these studies revealed that these vibrations were of two types: compression or P waves and shear or S waves.

你看，这些研究显示这些震动是两种类型：涨缩波或者说P波和畸变波或者说S波。

So the p wave and the s wave, and the different phases that move out from the site of rupture in the earth, are used by seismologists to locate the event.

地震学家用纵波、横波以及地球破裂部位移出的不同阶段来定位地震发生地点。

S waves, while slower, move the ground up, down, and side-to-side, perpendicular to the direction of the wave, causing great amounts of damage.

S 波虽然速度较慢，但​​会垂直于波的方向向上、向下和左右移动地面，造成大量伤害。

On the other hand, S waves either disappeared or were reflected back, so he concluded that the depth marked the boundary between a solid mantle and a liquid core.

另一方面，S波要么消失，或者被反射，所以他推断这个深度标示了固态地幔和液态地核的界限。

So we're a hundred kilometers back from the subduction zone, which like where I was in Japan, means that I have a I have a full minute of light P wave shaking before the S waves, the damaging waves, get to Corvallis.

- 所以我们距离俯冲带一百公里，这就像我在日本的地方， 这意味着我有一个完整的分钟光 P 波在 S 波， 破坏性波到达科瓦利斯之前摇晃。
