Comparisons between the latest observations and past studies of the early universe have shown differences in the estimated rates of expansion.

将最近的观测结果与过去对早期宇宙的研究进行比较，可以发现对宇宙膨胀速率的估计存在差异。

Although the rate of expansion slowed in July, it remained among the best registered over the past year.

虽然7月份扩张速度有所放缓，但仍处于近一年来最好的水平。

Present methods cannot investigate this type of expansion any more than they can investigate the validity, development, and rate of expansion of an idea.

目前的方法无法探究这种类型的扩展，就像无法探究一个理念的有效性、发展和扩张率一样。

The fact is, the rate of expansion would slow down only if the universe was filled with nothing but matter and radiation.

事实是， 只有当宇宙充满 物质和辐射时，膨胀的速度才会减慢。

Moreover, the rate of expansion of the universe would automatically become very close to the critical rate determined by the energy density of the universe.

而且，宇宙的膨胀率会自动变得非常接近宇宙能量密度决定的临界率。

Latest figures published in Beijing show China's economy grew by 6.7% in the first quarter of the year, the lowest rate of expansion since the depth of the financial crisis in 2009.

中国统计局公布第一季度GDP，增速值为6.7%，创2009年金融危机以来最低增速。

The initial rate of expansion also would have had to be chosen very precisely for the rate of expansion still to be so close to the critical rate needed to avoid recollapse.

初始膨胀率也必须非常精确地选择，因为膨胀率仍然非常接近避免重新坍缩所需的临界率。
