气体中氢含量的定量测定,在国防、宇航、普通工业及科学研究中具有广泛而重要的用途。例如防爆予警、微量探漏以及物理、化学、生物学等研究中测定氢气含量等。这些广泛的用途,对氢气含量的测量要求满足三个要求:测量能够准确定量且可测定范围宽,对氢气的选择性好和响应时间短。以往的氢敏元件都不能准确定量,而且选择性也不太好。近年来 Quantitative determination of hydrogen content in gas, in defense, aerospace, general industrial and scientific research has a wide range of important uses. For example, explosion-proof police, trace detection and physical, chemical, biological and other research determination of hydrogen content. For these broad applications, hydrogen content measurements are required to meet three requirements: measurement is accurate and has a wide measurable range, good hydrogen selectivity and short response times. The past, the hydrogen-sensitive components can not be accurately quantified, but also not very good selectivity. In recent years
