摘　　要：目的:通过分析研究盐雾环境对心电图机关键性能参数的影响,为提升海上医疗保障能力提供可靠依据。方法:在分析盐雾对卫生装备表面及内部电路板和器件的腐蚀机制基础上,利用4组不同盐浓度恒定应力的加速腐蚀试验,分析心电图机关键性能参数与盐雾浓度的变化关系。结果:随着盐雾浓度的增加,心电图机的技术性能和安全性能有所下降。结论:本研究数据可为提高舰载卫生装备环境适应性提供一定的参考,对降低海上救治平台医疗设备的故障率,充分发挥海上救治平台的救治能力有着重要意义。Objective： Through analysis and study of effects of salt spray on the key performance parameters of electrocardiograph, reliable evidence arc provided for enhancing the marine medical security ability. Methods： On the basis of analyzing how the salt spray corrodes the surface and the inside electron circuit boards and components of medical equipment, and by four salt spray tests with different salt concentrations and constant stress, this paper has analyzed the relations between the key performance parameters of electrocardiograph and salt concentration. Results： With the increase of salt concentration, the technical and safety performance of electrocardiograph are declined. Conclusion： This paper is intended to serve as a reference for enhancing the c nviro._nme_nt adaptability of the shipborne medical equipment. It attaches great importance to reducing the failure rate of the medical equipment on the marine medical platform. It also makes the platform work at full capacity
