The stress transfer model of the sensor is analyzed and the relationship between the change of Fabry-Perot gap length and hydrogen concentration is constructed.
分析了其应力的传递过程，建立了法布里-珀罗腔腔长变化与氢浓度关系的数学模型。
Depending on that, suggest place a dispersive sensor upside down at the wellhead and a suction sensor at the cellar to test the hydrogen sulfide concentration accurately.
针对以上情况，建议在井口处安装倒置放置的扩散式传感器，方井处安装吸入式传感器。从而能更准确检测硫化氢浓度。
