If the density just equals the critical density, the universe is flat, but still presumably infinite.
如果密度正好等于临界密度，宇宙则是平坦的，但很可能仍然是无限的。
While the answer is not yet known for certain, it appears to be tantalizingly close to the critical density.
虽然并没有确切的答案，但它似乎已经非常接近临界密度。
The value of the critical density is very small: it corresponds to roughly 6 hydrogen atoms per cubic meter, an astonishingly good vacuum by terrestrial standards!
临界密度的值非常小：它相当于每立方米约6个氢原子，从地球上的标准来看这简直是真空！
The critical density of 1-hexene was determined by "the law of rectilinear diameter".
用“对径直线律”确定了1-己烯的临界密度。
