Actually, what that would say, and we are going to see more about that so not very important right now, but what we would see is that for a close surface we would end up getting zero for the flux.

也就是这样了，现在来看点没那么重要的东西，对于一个封闭的曲面，如果通量为零。

Flux is going to be zero because nothing passes through the surface.

通量之所以为零，是因为根本没有东西通过曲面。

It's not clear why this extrapolation was used or what conclusions can be drawn from it; the molecular surface tension could just as easily be asymptotic with respect to the zero point.

外推的原因和结论都不清晰，分子表面张力也可能是渐进趋向于零。

Additionally, to thoroughly eliminate ghosting and lens flares, reflectivity was kept to half of the previous value at a wavelength of 450 to 650 nm, thanks to the lens surface treated with the Olympus-original ZERO (ZUIKO Extra-low Reflection Optical) coating.

To compare alien planets, Dr. Mendez at the Planetary Habitability Laboratory and his colleagues are creating an Earth Similarity Index that ranks worlds by their resemblance to our own planet, on a scale from zero to one, based on their mass, radius, density and surface temperature.
