An RF power meter has one major drawback: it cannot measure frequency, so it may give an "approved" rating to a defective mobile telephone, as in the following two examples.
功率计的一个主要缺点是：不能测量频率，因此它会对一个有缺陷的手机给出“通过”，就像下面的两个例子。
As an example, Finite element analysis and optimization design are made to a voltage transformer of rating primary voltage 35KV, rating secondary voltage 100V, rating frequency 50HZ.
并以额定一次电压35KV，额定二次电压100V，额定频率50HZ的电压互感器为例，进行了有限元分析计算和优化设计。
The report also provides a five-star rating guide for 200 popular U. S. beaches, based on indicators of beach water quality, monitoring frequency and public notification of contamination.
根据海滩水质指标，监测频次和污染公告，报告也为美国200个受欢迎的海滩提供了五星级的评级。
Not only the deviation of voltage and frequency from the rating value or other traditionally focused problems, but also the dynamic disturbance phenomena including oscillation and pulse are concerned.
人们不仅关注传统意义上的供电可靠性、稳定性以及各种参量偏离标称值问题，而且也对诸如振荡和脉冲之类的动态扰动现象开始重视起来。
