The method can realize time variant merging automatically, result in simultaneous corrections both for phase and amplitude and avoid the influence of noise.

此方法可自动实现时变拼接，达到相位和振幅同时校正，而且能避免噪声的影响。

First, the generation mechanism, components and frequency characteristic of radiated noise of naval ships are studied. There exists periodical modulation for the amplitude of propeller noise.

首先讨论了舰船辐射噪声的产生机理、构成和频率特性，指出螺旋桨噪声的振幅存在周期性调制。

The amplitude distribution of narrow hand semiconductor noise in junction type OC70, OC71 and point contact type 2N32A transistors were measured experimentally by the "maximum amplitude" method.

本文中描述用振幅峰值的方法，测量面接触型晶体管OC70，OC71和点接触型晶体管2N32A内窄频带低频率噪声的振幅分布。
