一、前言记录仪用铂钴永磁材料是杭州市无线电研究所研制的心电图机上记录仪用的随动元作。当输入讯号后,铂钴合金在磁场的作用下带动喷笔绘制出各种波形。目前国际上心电图机有三种类型:1.热笔式;2.墨水式;3.喷射式。热笔式和墨水式记录的波形,是采用和记录纸直接接触的方法绘制,因摩擦使得精度差,而喷笔式是喷笔将墨水喷到记录纸上,它可以逼真记录各种心电、心音波形,并能精确诊断一些疑难病症,频率范围
First, the foreword Recorder with platinum and cobalt permanent magnetic material is developed by the Institute of Radio Institute of Hangzhou ECG recorder with the follow-up for. When the input signal, the platinum-cobalt alloy under the action of a magnetic field to bring a variety of waveforms drawn. Currently there are three types of international electrocardiogram machine: 1. Hot pen; 2. Ink; 3. Jet. Hot pen and ink-based recording of the waveform, is used and direct contact with the recording paper drawn, due to friction makes the poor precision, and pen-type pen is the ink jet to the recording paper, it can vivid record a variety of ECG , Heart sound waveform, and can accurately diagnose some difficult conditions, the frequency range
