After analysing the acoustic data and the difference blocks geotechnical data of the modern Huanghe estuary, we find that the differential erosion and failure behvior of soil in the slope are controlled by sedimental geotechnical properties: The counter failure ability of soil with a low clay content(<10%), high water content(30%~45%) and large void ratio(0.

This paper expounds two technique for intrusion detection: anomaly detection and misuse detection, and introduces the category and many intrusion detection techniques of IDS.

Considering the defects existing in Gini coefficient, this paper analyzes the income gap among the rural residents in the eastern, central and western regions of China.

Recently the rural residents’ income gap in different districts has been increasingly enlarged,which affects the stable development of the overall economy in China’s rural districts.

China has achieved rapid development economically in recent years while seeing an increasingly widened income discrepancy.

The positivism research results from the analysis of statistical data since 1978 show that the development of education in our country in recent decades has not only increasingly widened the income discrepancy between urban residents and rural residents but also the economic growth gap of different areas.
