Track irregularity is objective existence, it cant be eliminated. But, we can formulate reasonable repair and maintenance plans to increase the efficiency of track maintenance and ensure safety, if the prediction of track irregularity is effective. In this paper, on the basis of analyzing on the irregularity forecast method and the "memory" of ballast track, a method based on most possible similarity model is introduced. This method is going to find irregularity in history most close to the current, and use its development to predict the current development. The longitudinal level irregularity of Hefei-Wuhan line was predicted, and results indicate that prediction graphics were consistent with the actual graphics in trend. So, using this model to predict development trend of track longitudinal irregularity is feasible.

Cross-border e-commerce is based on the Internet, and the traditional way of international trade is distinct. Under the development trend of global economic integration, cross-border e-commerce is facing a new opportunity for development. Although there are many differences between cross-border e-commerce and traditional transactions, they still face common problems in cross-border transactions. This paper mainly discusses the impact of cross-border e-commerce on China's foreign trade and the current development of cross-border e-commerce, especially the shortage and training of cross-border e-commerce complex talents, which aims to promote the vigorous and smooth development of cross-border e-commerce in China.

The application of Ultraviolet Imaging Technology (UVIT) in the electric equipment Partial Discharge (PD) was proposed and the operating principle of Ultraviolet Imaging Technology Instrument (UVITI) was analyzed in the paper. By describing the current development trend of UV imaging technology in China and foreign country, the several factors influencing the detect accuracy of the UVITI was analyzed. The results show that: the environment temperature, the back light, the air humidity, the instrument gain level, the wind level and the measurement distance will influence the accurate measurement of PD level and location seriously. In order to detecting the PD level and locating the fault position accurately, electric equipment PD measurement should be taken in low environment temperature and humidity, short measurement distance and avoiding big wind. For the disturbing of environment noise on measurement signal, the instrument gain level should be improved.
