摘　　要：针对传统湿度发生器存在的诸多缺点,在总结和吸收国内外对湿度发生器研究成果的基础上,根据在不同温度定点条件下和饱和盐水溶液共处于平衡状态的空气相对湿度仅仅是温度的函数,引入微机控制系统,实现自动温度控制,研究开发了能够产生连续湿度定点的湿度发生器,使湿度传感器或其他小型湿度仪表的校准更为快捷和准确。这种类型的湿度发生器在国内还是首创,具有重要的研究与实用价值。Because there are many disadvantages in traditional humidity generators, based on summarizing and absorbing the research achievements of humidity generator, and relative humidity of the air which in equilibrium state with saturated salt solution is just the function of temperature, the authors researched and developed a humidity generator which could generate gas with continuous value of humidity. In this development, microcomputer control system was used to automatically control the temperature. The research and development of this type of humidity generator filled the equipment gap in China. Therefore, the humidity generator has significant values of research and practicality.
