设计了表征金属氧化物涂层结构的综合实验。以 RuO2和（Ru ，La）Ox 涂层为研究对象，利用 SEM ，EDX ， XRD 以及 DSC 等实验手段，研究稀土元素 La 对涂层表面结构的影响。研究结果表明，La 的加入导致 Ru‐La 氧化物涂层表面形貌以裂纹泥形式出现，涂层中 RuO2晶体的含量降低，氧化物更多以非晶态形式存在，这是引起催化活性增加的主要原因。该实验设计通过一个研究项目将理论知识与多项实验内容紧密结合起来，有助于培养学生独立思考及综合运用知识来分析解决问题的能力。

A comprehensive experiment of characterization of the metal oxide coating structures has been designed .For RuO2 and (Ru ,La)O x coatings ,the effects of rare earth element La on the coating surface structure have been studied by means of SEM ,EDX ,XRD and DSC .The results show that the surfaces of the Ru‐La oxide coatings show the cracked‐mud morphology with the addition of La species .The amount of RuO2 crystal decreases on the coating surface ,where the Ru‐La oxides show more in the form of the a‐morphous phase .This is the main reason for the catalytic activity of the coatings increased .This experi‐mental design has correlated theories to practical experiments by carrying out a project , helping the students to develop the ability of critical thinking and problem solving depended on what they learned .
