So it is easy to get different frequency surface effect depth.

可以方便地求出不同频率的趋肤深度。

Thus, complementary codes are fit for high-frequency surface wave radar.

因此，在高频地波雷达中适合采用互补码信号。

High frequency surface wave radar is an important tool of the over horizon detection of sea and low-altitude targets.

高频地波雷达是对海面、低空目标进行超视距探测的重要手段。

So, for example, we were talking about a threshold frequency as in a minimum frequency of light that you need in order to eject an electron from a metal surface.

举个例子来说，我们谈论的临界频率是,光从金属表面逐出一个电子,所需的最小频率。

麻省理工公开课 - 化学原理课程节选

The fifth is the observation in reality of a predicted link between increased sea-surface temperatures and the frequency of the most intense categories of hurricane, typhoon and tropical storm.

ECONOMIST: Changing science

Further, with more frequency than attorneys feel comfortable admitting, errors in existing documents may surface requiring corrective action.

FORBES: "Fixing" the Broken Estate Plan

The machine that Dr O'Brien and Dr Frazier have designed to get round these constraints consists of a transmitter that sends out a pulse of sound at a frequency of 6 kilohertz, and an array of 52 receivers that collect the reflections from anything buried beneath the surface.
