For example, the focal length of an 8" (203.2mm) aperture with a focal ratio of f/10 would be 203.2 x 10 = 2032mm.
比如，孔径为8英寸(203.2mm)，焦比为f/10的透镜，其焦距为203.2x 10 = 2032mm。
In such a cases the ratio of X to Y in the solution usually reflects the ratio of people voting for each alternative.
在这种情况下，在解决问题办法中的x和y的比例通常反映了成员们为二者投票的比例。
If in the next release, you see a 30 percent improvement in the NRPC and 15 percent in client x, then the ratio becomes 2.45:1.
如果在下一版本中，NRPC有30%的提高，而客户机x有15%的提高，则比例变为2.45：1。
For a life data x, whether it comes from the censoring exponential distribution or the censoring normal distribution, it can use the likelihood ratio test to make a decision.
对给定的寿命试验数据x，利用似然比检验法可对该数据是来自截尾指数分布还是截尾正态分布进行判别，但却很难求出似然统计量的分布形式。
By employing the characterization methods of X-ray and DSC, this paper conducts a research on films of different stretch ratio.
通过X—射线、DSC等表征手段，我们对不同拉伸程度的薄膜进行了研究。
