查询词典 noise

On the base of analyzing the main factor to the erroralarming in LPMS,the alarming theory in view of wavelet's RMS was established by choosing minor scale of relative noise as alarming datum point,and the base noise which affect alarm was checked effectively.

在分析LPMS中产生误报主要原因的基础上，结合小波时频域分析特点，提出了基于小波均方值报警理论，并以秦山核电站一号机组为例，选择相对噪声较小的尺度作为报警基准，能有效地抑制背景噪声对报警的影响。

It is the first time to calculate the near noise field with ray method, and replace the inhomogenous SSP in the vertical direction with constant SSP, while other models usually use Fast Field Program such as SARFRI to calculate the near noise field.
