When towed fish is towed in the direction perpendicular with the lineation of hinge line of sand waves, the wave length and dipping angles, can be determined from the sonar image at nadir. Under the circumstance, whether the shape of the sand wave is symmetric or not can be shown and the main direction of sediment transportation can be pointed out.

依据相对大尺度的砂波，在拖鱼指向与砂波脊线成大角度斜交时，该波形可在拖鱼正下方影像显示，并且可以辨识该波长与坡倾角，以判定此砂波为对称波形，或非对称波形，来指示沉积物的净搬运方向。

In order to solve the problems of bad shunting and red light strip phenomenon at electric railway section caused by the defective of asymmetric pulse track circuit receiver formerly, a new type of asymmetric impulse track circuit receiver is designed. It takes the PIC16F887 single-chip microcomputer as central processing unit of the system, realizes processing and judging the asymmetric impulse from the track transformer automatically. The article focused on the receiver work flow, hardware circuit and software design.

摘 要：为了解决以往多数不对称脉冲轨道电路接收器存在缺陷而导致的分路不良问题和电气化区段空闲&红光带&现象，设计了一种新型脉冲轨道电路接收器，系统以PIC16F887单片机为核心处理单元，自动实现对由轨道变压器传来的不对称脉冲信号进行处理和判决，重点讨论了接收器工作流程、硬件电路实现以及软件设计。
