In this paper,sludge was pretreated by heat to enhance anaerobic fermentation hydrogen production .

通过对污泥进行热处理来提高污泥厌氧发酵产氢的能力。

SF and collagen films were treated by negative corona discharge, homothermal surface potential decay was tested to detect the charge stability. Result showed circums- tance humidity influenced severely the surface charge stability. There were polar groups on the surface after corona discharge, and hydrogen bonds existed between these groups. On the other hand, ATR-FTIR analysis indicated the conformation transition of SF was induced by strong electric field and a part of random coil conformation was converted into β-sheet structure.

采用自制的负电晕极化装置对丝素、胶原膜进行了表面处理，等温表面电位衰减法测试材料在不同环境中表面电位的变化，发现环境湿度对材料表面电荷稳定性的影响较大；XPS光谱分析表明材料表面有极性基团产生，这些基团之间有可能会形成氢键，同时ATR-FTIR分析表明丝素的构象在强电场的作用下发生了变化，由无规线团转变为β折叠结构。

When alloy is redeposited, the places where hydrogen was adsorbed begin to preferentially nucleate and grow. It cut off the ways that needle holes form.
