测量实船马力是一个历史悠久的问题,半世纪以来人们先后设计出利用各种原理的扭力仪达数十种之多,本文将迄今为止所见到的扭力仪分门别类,归纳为机械、光、声、电、磁等各种型式,并将其中有代表性的作一有系统的介绍,说明各该仪器的优缺点。本文也指出船舶上使用的扭力仪所必须具备的待点,如结构方面必须坚固,牢靠,耐震,在使用方面必须简便,使一般人员都能操作管理。此外,又着重指出在设计时所必须特别注意的机械装置问题,因为有好几种扭力仪的试造失败,是由于太偏重了拾微器部份,而忽视机械装置所引起的。作为一个实船扭力仪的具体例子,本文介绍了在船模试验所里试造的那一种电感式扭力仪。这套扭力仪是专为船舶工业管理局设计建造的250马力渔船上应用的。

The detecting of underwater acoustic waves by means of photographic techniqueis becoming attractive as the image can be processed by electronic computer or opticalequipment so as to increase the sesitivity of detection.The underwater acoustic signalscan be converted directly into visible image.As each pixel of the image is a two-dimensional function,it has more eigen information than is obtained by using generalpizoelectric transducer which usually gives information of one-dimensional functiononly.Therefore it is advantageous to the increase of the signal-to-noise ratio.In the experiment described by this paper a spatial filter is used for processingthe image of the signal waves and the enhancement of the image is accomplished bycomputer.The processed image is photographed as shown attached.

利用声波图象来检测水声信号是一个有趣的方法。信号图象可以通过电子计算机或光学元件来进行加工处理,从而提高检测的灵敏度。水声信号图象化检测能够直接显示水声信号的形象。由于图象中的每个象素是一个两维函数,所以它的特征信息量多于一般声电换能器所获得的一维电信号信息,因而有利于提高接收信号的信噪比。在本文的实验中,将收到的信号声波图象进行了空间滤波并在计算机上作了增显加工,并摄取了它的相片。
