The paper involved two parts: Part 1: A two-chambered microbial fuel cell was constructed with high-concentration sodium acetate as fuel in the anode. The influence of different electron acceptors in the cathode, external resistance value, pH value and concentration of sodium acetate on electricity generation in MFC was investigated. The result showed that the maximum power density of 294.72 mW/m2 and the coulombic efficiency of 25.87% was achieved at sodium acetate concentration of 6.46 g/L, pH 7.0, external resistance 500Ωin the anode and when using potassium permanganate as electron acceptor in the cathode.

On the basis of the characteristics of line boundary, this paper analyzes the different features of internal and external faults. The difference is that the ratio of high frequency to low frequency components in case of one external fault is less than that in case of the same internal fault, in which high frequency is in the band of line trap and low frequency is within 1~10kHz.

在线路边界频率特性的分析基础上，深入地分析了区内外故障时的特征差异：就某一类故障而言，区外故障时反行波中高频分量与(1~10kHz内的)低频分量的比值显著小于区内故障时的比值。

Three-pass differential interferometry, ultrashort baseline and external DEM based repeat-pass SAR interferometry are employed to assess the seismic displacement.The final results show that the external DEM based repeat-pass InSAR is better than three-pass differential method in such area.

本研究分别进行了三路差分干涉、超短基线重轨干涉和基于外部DEM的重轨干涉处理方法的实验，对于结果的对比分析表明，基于外部DEM的重轨干涉方法在该类地区应用效果优于三路差分方法。

In the aspect of structure line detection, the main idea is to separate the roof structure lines into two parts, one is for external contours and the other is for internal structure lines. The external contours were extracted using Hough transform and other geometric conditions. The internal structure lines were extracted by any two adjacent roof faces intersecting each other. Finally, the two kinds of structure lines were combined to construct the roof shapes.
