phase only information 纯位相信息
Adding this sort of information to product labels can encourage buyers to minimise the use-phase emissions-but only if they actually read the label and act on its advice.
在产品标签上加上这种信息能够劝导购买者将使用阶段的排放减少至最低——但只有当他们的确领会了标签并且按照那个建议去做。
Usually the radar video signal is used to detect, but it only utilizes the amplitude of the signals and lost the information of phase and frequency of radar signals.
以往的目标检测都是在视频信号上进行的，它只对回波幅度进行检测，而丢掉了信号的相位和频率的信息。
The experimental results show that the double-exposure can not only obtain directly the phase information, where it doesn' t need laser reconstruction, but also gives quantitative results.
实验结果表明两次曝光技术不但能直接获取位相信息，不需要激光再现，而且能给出定量结果。
