大型电子医疗设备在使用过程中所出现的各类故障，因客观因素导致的故障例约占三分之一左右。这已是众多工程人员早已达成的共识。尽管客观因素，诸如：温度、湿度、接地等会对设备的性能有直接影响这一道理早已家喻户晓，但设备出现故障时，人们又往往会忽略客观因素，因而使 The breakdown of various types of failures in the use of large-scale electronic medical devices due to objective factors accounts for about one-third of the cases. This is already the consensus reached by many engineering personnel. Although objective factors such as temperature, humidity, grounding, etc. will have a direct impact on the performance of the equipment, the reason is that when the equipment fails, people often ignore the objective factors, so that
