And let's assume that this structure is very lightweight, so that we can ignore that, and let this distance be ten meters.
假设这个结构，非常非常轻，轻到可以忽略，这段距离是10米。

The researchers found that in the northern sky, the fine-structure constant gets smaller with increasing distance, or as astronomers look farther back in time.
研究人员发现在北方天穹，精细结构常数在越远的地方就越小，或者说天文学家所看到的过去越久远。

In this paper, the traditional streaming media technology on the basis of the structure proposed hybrid P2P streaming model, to further optimize distance education systems.
