应用Devanathan-Stachurski电化学氢渗透速率的测定原理和杜元龙的发明专利；研制了一种在加氢反应器上使用的电化学氢探头（HR型氢探头）该探头在循环冷却水温低于323K的温度以下变化时．其背景电流密度小于0．6μA·cm－2．温度对稳态氢渗透电流密度有较大的影响，测量过程中需要恒定氢探头的温度，经对HR型氢探头标定，用i∞＝1195iH表示稳态氢渗透电流密度．能精确地计算出金属材料中可移动原子氢的浓度，HR型氢探头可用于接触高温金属构件的渗氢测量
Application of Devanathan-Stachurski electrochemical hydrogen permeation rate determination principle and Du Yuanlong’s invention patent; developed a hydrogenation reactor electrochemical hydrogen probe (HR-type hydrogen probe) the probe in the cooling water temperature below 323K When the temperature changes below. The background current density is less than 0.6μA · cm-2. The temperature has a great influence on the steady-state hydrogen permeation current density. During the measurement, the temperature of the hydrogen probe needs to be constant. After HR HR probe calibration, the steady-state hydrogen permeation current density is represented by i∞ = 1195iH. Accurately calculate the concentration of mobile atomic hydrogen in metal materials, HR-type hydrogen probe can be used for contact with high temperature metal components of the hydrogen permeation measurement
