随着科学技术的发展,湿度的测量和控制在工业、农业、交通运输、国防以及尖端科学中的应用具有十分重要的意义.因而,湿度的测量引起了国内外科技界和生产单位的高度重视,也相应地对测量方法和测控仪器提出了更严格的要求.但是,标量湿度的仪器中有很大一部分是以实验为依据的,这类仪器必须通过标准来校准.事实表明,基于不同原理的仪器,有时即使是依据相同的原理,乃至同一制造厂生产的同一型号和同一批仪器,对同一测量对
With the development of science and technology, the application of humidity measurement and control in industry, agriculture, transportation, national defense and cutting-edge science is of great significance.Therefore, the measurement of humidity has attracted great attention of the scientific community and production units at home and abroad , But also the more stringent requirements for measurement methods and measurement and control instruments.However, a large part of the scalar humidity instruments are experimentally based, and such instruments must be calibrated by standards. The facts show that based on different principles Of the instruments, and sometimes even based on the same principle, and even the same manufacturer’s production of the same model and the same batch of instruments, the same measurement pair
