1．引言本文所述的CO。测试仪中所使用的传感器是一种可逆的，没有损耗的化学涂膜传感器。涂膜材料是一种酸性的指示剂，通常是在液态下贮存的。当将它涂抹在玻璃片上后，其中的挥发成分会很快挥发掉。而后在玻璃片表而形成一层很薄的透明膜。这层薄膜完全不溶于水，可以在很宽
1. Introduction The CO described in this article. The sensor used in the tester is a reversible, lossless chemical coating sensor. The coating material is an acidic indicator and is usually stored in a liquid state. When it is smeared on a glass slide, the volatile components will evaporate quickly. Then a thin transparent film is formed on the glass sheet. This film is completely insoluble in water and can be very wide
