In order terms, the Euclidean space time is a closed surface without end, like the surface of the Earth.

按规则来说，欧几里间-间是一个没有尽头的闭合曲面，就像地球表面。

In Euclidean space-time there is no difference between the time direction and directions in space.

在欧几里中，间方向和间方向之间没有区别。

What we now call Euclidean space-time is very similar except that it has four dimensions instead of two.

我们现在所说的欧几里德常相似，只是它有四个维度而不是两个维度。

To do this, we must perform the sum over histories for all possible Euclidean space-times that have no boundary.

为此，我们必须对所有可能的无边界欧几里的历求和。

Yet, in truth, there is no remedy except to throw over the axiom of parallels and to work out a non-Euclidean geometry.

然而，事实上，除了抛开平行公理并计算出欧几里德几何外， 别无补救。

In the Euclidean approach, the history of the universe in imaginary time is a four-dimensional, curved surface like the surface of the Earth, but with two more dimensions.

在欧几里方式中，虚宇宙历是一个四维曲面，就像地球表面，但多了两个维度。

The classical theorists resemble Euclidean geometers in a non-Euclidean world who, discovering that in experience straight lines apparently parallel often meet, rebuke the lines for not keeping straight-as the only remedy for the unfortunate collisions which are occurring.

古典理论家类似于欧几里世界中的欧几里几何学家，他们发现在经验中看似平行的直线经常相遇，斥责直线不保持直线——这是对正在发生的不幸碰撞的唯一补救措施。

The white pyramid in the distance compelled the mind's assent as passionlessly as a Euclidean theorem, and when at last the sun rose into a sky of deep delphinium blue, he felt only a little less than comfortable again.

远处的白色金字塔像欧几里定理一样冷酷无情地强迫人们同意，当太阳终于升入深翠鸟蓝的天，他又觉不太舒服了。
