15px;">诊断</span></span>工具之一，但</span><span style="font-size: 15px;">其作为精密复杂的医疗电子设备，极易受到多种因素的影响而导致无法正常工作，长时间的连续工作，底线接地电阻增大，电源剧烈波动甚至瞬间停电，各种灰尘及纸屑造成散热不良以及误操作等多种原因都有可能导致设备出现故障，因此对其故障及时进行处理显得尤为重要。</span></p><p><span style="font-size: 15px;"><br /></span></p><p><span style="font-size: 15px;"><span style="font-size: 15px;">其中最易受干扰的就是各种电磁场的干扰，常见的外部干扰引入超声设备的途径大多为以下两种：</span><span style="font-size: 15px;color: rgb(0, 92,
