In astronomy, in optical astronomy, we cannot measure the period or the frequency of optical light.

在天文学中，在光学天文学中，我们不能测量周期或者可见光的频率。

You might ask the applicant to provide some measure of the expected frequency and severity of failures.

您可能会要求应用程序提供一些预计频率和失败的严重性的方法。

Otherwise, you might ask the application to provide some measure of the expected frequency and severity of failures.

否则，您可能会要求应用程序提供一些预计频率和失效的严重程度的方法。

So, one thing they did, because it was so easy to measure kinetic energy of electrons, is plot the frequency of the light against the kinetic energy of the electron that's coming off here. And in your notes and on these slides here, just for your reference, I'm just pointing out what's going to be predicted from classical physics.

他们做的其中一件事,因为测量电子动能是很容易的，就是画出光的频率,和出射电子动能之间的关系,在讲义的这里，仅仅是,为了做个比较，我要指出，经典物理所给出的预测,这个不作为对你们的要求。

The Australian research focused on the thermal effects or specific absorption rate (SAR) of radio frequency radiation - a measure of its actual effects on brain tissue, whereas the earlier study simply looked at electromagnetic radiation levels.

To measure the frequency of repairs for a particular vehicle, it compared the percentage of reported check engine failures for that model to its share of all 136 million 2002-2012 model-year vehicles on the road.

Ranger IV was also equipped with a seismometer and radio transmitter, designed to be released in a small capsule from the rocket before impact and land on the Moon in sufficiently good condition to measure the frequency of natural earthquakes in the body of the Moon.
