分别以砂浆抗压强度、粉煤灰单位强度因子为指标研究了砂浆体系中粉煤灰的最佳掺量范围。

The concept of fly ash-saturation was put forward based on the index of maximum compressive strength and optimal unit strength factor of fly ash in cementing materials, respectively.

在给定信号强度和噪声水平的情况下，以比特每秒为单位给出的最终限制是无差错通信的最大绝对速率。

The resulting limit, given in units of bits per second, is the absolute maximum rate of error-free communication given signal strength and noise level.

But in terms of SI units, which become much more useful if you're actually trying to use intensity in a problem and cancel out your units, we're just talking about joules per second is what intensity is.

但是用国际单位制，这个变得越来越有用了,如果你实际上在使用强度,来解决问题和约化单位，我们仅仅讨论每秒钟的焦耳,这就是强度。

And when we talk about intensity in terms of units, we usually talk about watts, so if you change your lightbulb, usually you see the intensity in terms of watts.

当我们讨论强度的单位时，我们经常用瓦特，所以如果你更换灯泡，你通常会看到,以瓦特为单位的强度值。
