不能用来测量频率，在信号处理之前所有的频率信息都将丢失。

It does not measure frequency, since all frequency information is lost before signal processing begins.

提出一种仅需要频率信息就可以识别结构损伤的附加质量方法。

The paper also discussed the means of determining the number, placement and size of the added masses.

例如，您可以创建团队区域参数和开发行参数，以筛选工作项目和参与者的使用频率信息。

For example, the team area parameter and develop line parameter can be created to filter the work items and the contributor's utilization rate information.

So, we should be able to look at different types of waves and be able to figure out something about both their frequency and their wavelength and know the relationship between the two.

我们可以看到,不同的波并从它们的,波长和频率中,获得一些信息，我们知道。
