实验结果表明，影响顺酐收率的主要因素是催化剂的相组成及钒的氧化态，而不是催化剂的比表面积。
The main factor influencing the yield of maleic anhydride is the phase composition or oxidation state of vanadium in the catalyst, and is not the BET surface area of the catalyst.
谱峰分解法系以每种钒氧化态的标准谱形函数为基础，用最小二乘法求解。
The peak resolution method is least square method based on the standard spectral profiles corresponding to each oxidation states of vanadium.
因此，形成价态更高的钒氧化物薄膜。
Therefore, formation of high valance vanadium oxide films was obtained.
