Many fluorescence images are taken in single channel images which are often merged to generate a single overlapped image.

很多荧光图像拍摄于单通道模式下，有必要合并生成单一的叠加图像。

Two vertical edges of the utility model are overlapped and welded up or glued to form a main channel and an assistant channel.

此外，副通道以所需的一定间隔横向或斜向焊封或胶粘而分隔成纵向节段；

Aiming at time-frequency overlapped two-signals in single-channel, this paper proposed a method to estimate carrier frequency based on second-order cyclic cumulants.

针对单信道中时频重叠双信号的载波频率估计问题，提出一种基于二阶循环累积量的载波频率估计方法。
