回到初始

研究表明Pt-DEB薄膜QCM传感器在室温下对于瓦斯气体CH4的敏感特性，发现对CH4气体发生吸附过程后，很难回到初始频率，并且对不同浓度的瓦斯气体响应灵敏度呈非线性。

By studying the sensitivity of Pt-DEB thin film sensor to methane gas CH4 , the film sensors was hard to return to initial frequency after the absorption of CH4 . And the sensitivity to CH4 with different concentration presented a character of nonlinear .
