引言研究海浪的物理性质时,必须取得波浪要素(周期、波高)的资料.对于表面波,由目测法、照相法及仪器自记法均可获得大量资料.对于海底压力波,则只能用自记法求得.一般可用电感式、电阻式、电位计式及热电堆式等自记仪来记录压力波.此地是介绍最后的一种形式. Introduction When studying the physical properties of waves, it is necessary to obtain information on wave elements (periods and wave heights), and for surface waves, a great deal of information can be obtained from visual methods, photographic methods and instrument self-recording methods. For submarine pressure waves, Self-memorial method is generally available inductive, resistive, potentiometer and thermopile self-record instrument to record the pressure wave. Here is the introduction of a final form.
