Looking back over the development of physics we see that the ether, soon after its birth, became the enfant terrible of the family of physical substances.

回顾一下物理学的发展，我们看到以太自出生以来便是具体物质这个家族中的一个顽童。

Since we have no mechanical picture of the ether, it is extremely difficult to answer this question.

因为我们没有以太的力学结构，所以很难答复这个问题。

Why all attempts to detect effects of Earth's motion through the ether had failed.

为什么所有测量地球在以太中的运动速度的实验都没有成功。

Far in the past, they had conquered the ether

在遥远的过去，他们已经征服以太

But there are other and simpler objections to ether than the difficulty of constructing it.

把以太说成是胶状的物质已经很困难了，但是还有其他更简单的反对它的理由。

This thesis mainly introduces the design and realization of Desktop Ether LAN Tester.

本论文对台式以太局域网测试仪的实现进行了深入、细致的研究。

The first, that moving bodies carry ether along.

第一个是说运动的物体把以太带走。

Your second argument is also true. We cannot give a mechanical explanation of ether.

您的第二个反驳也是对的，我们不能够对以太作一个力学的解释。

But what was the mysterious ether through which it passed?

但它穿越的那个神秘的以太是什么呢？

You are in a place called the Ethereal plane that overlaps the normal physical, Material Plane.

你处于以太位面，这是一个与主物质位面重叠的位面。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.
