本文描述一种新的声图仪,它被加进许多新的和独特的自动化特色。机械组件包括可进行连续录放的磁带操作系统。机械组件的一个重要部分是磁带扫描机构和灼筒。此扫描机构能重复扫描磁带上任意2.4秒片段以供谱图分析用,并为了连续分析所录信号,磁带可以自动顺次前进。高的速率使得做一张谱图只要80秒。谱图可以有三种基本类型:(1)标准的时间对频率的显示,以黑色的浓淡表示强度;(2)幅度等电平显示;(3)横截面幅度显示。
This article describes a new sonotrode that incorporates many new and unique automation features. The mechanical components include a tape operating system that allows continuous recording and playback. An important part of the mechanical components are the tape scanning mechanism and the barrel. This scanning mechanism can repeatedly scan any piece of tape on the tape 2.4 seconds for spectral analysis, and in order to continuously analyze the recorded signal, the tape can automatically go forward one by one. The high rate makes making a spectrum as long as 80 seconds. There are three basic types of spectrograms: (1) standard time vs. frequency display with intensity in black shades; (2) amplitude equal level display; and (3) cross-section amplitude display.
