Generally, the horizontal gravity gradient map resulted from Bouguer anomaly reflect quite well the planar distribution of the faults with large scale in the area of XX block under study. But volcanic rocks developed at some locations in Eocene may disturb, to some extent, the extraction of fault information from gravity anomalies, therefore only gravity data are constrained for proper interpreting the faults in the basement. On another hand, the information of magnetic anomaly, especially paternoster magnetic anomalies and the magnetic anomalous features depicted by the first- vertical derivative map are mainly related to faults. This paper presents a case to identify the fault system by using gravity and magnetic data, and finally the reliable fault system is inferred.

This paper suggests a simple use-case modeling method integrating the method of use-case modeling in UML and OML. The method gets rid of generalization, extend and including relationships among use cases, and introduces the generalization relationship among actors, the use relationship between actor and use case, the precede relationship among use cases, two levels view and two kinds of use case diagrams to express the requirement model.

Bioventing and microbe composting methods were used in the laboratory to simulate the remediation of the diesel-contaminated soil. Consequently the contaminants removal paths and mechanism were discussed. The results showed that these two methods were effective in the remediation process. After 45 days, over 64% diesel was removed from the soil given the original oil content at 5.00×104mg•kg-1. The rate constant of biodegradation and half life was 0.0384d-1 and 18.05d, respectively. Biodegradation was the main way of contaminant removal. Volatilization loss of diesel oil was less than 2.5% of initial diesel oil content. Among the three ratio of contaminated soil to sewage sludge (dry weight) with the ratio of 8:2, 7:3 and 5:5 respectively, the highest removal of diesel oil was observed in the ratio of 7:3, in which the removal of complete biodegradation reached to 73.59% of the total removal.

In modification experiment the best modification method was established. First, natural zeolite was roasted at 600¿ in a muffle furnace for 2h. After cooled to normal temperature, it was soaked in 4% HCl solution on dynamic condition at 65¿ for 1 hour, then soaked in 1mol/L NaOH solution on dynamic condition at 40¿ for 1 hour. The preconditioned zeolite was then was soaked in 10%AlCl3 solution on dynamic condition at 40¿ for 20 hour. In the end, it was treated in water vapour for 1 hour. Static experiment was carried out in order to examine defluorination ability of modified zeolite. The results showed that the adsorption capacity of zeolite was greatly enhanced after being modified, which obtained 0.25mg/g for fluoride solution with 20mg/L concentration. There were many factors affecting the adsorption capacity of modified zeolite. Among all the factors, the pH value and concentration of raw water and the running speed in dynamic experiment had greater influence. The structures of natural zeolite and modified zeolite were observed by SEM, XRD and FT-IR. Based on these, the reason and effect of modification were further analyzed.

The best experimental factors were achieved through the single factor experiment and orthogonal experiment. When the initial concentration of formaldehyde was 120mg/L, reaction time was 30 minutes and the ratio between amount of sodium bisulfite and formaldehyde was 3:1, the removal rate of formaldehyde was approximately up to 100%, which fully satisfied the national emission standards (the concentration of formaldehyde≤ 1mg/L). The actual wastewater project was verified according to these factors. The tannery wastewater containing formaldehyde which the initial concentration of formaldehyde was 120mg /L was reacted with sodium bisulfite. The concentration of remaining formaldehyde was reduced to 0.446mg/L 30 minutes later, which fully satisfied the national emission standard. The process was practicable.

Under the policies' support and government incentives, wind power has seen a dramatic increase both in the size of wind turbines and the amount of wind power generation these years. Therefore, it is very important to understand the degree to which the conventional generation system can withstand the wind power and new changes on the performance of grid brought by the integration of wind power, especially on the profile of voltage and transient stability. By simulation, this paper will give a case-based analysis on the wind power penetration limit from a new perspective of different network contingence as well as a general conclusion. This paper is also extended to include analysis of the inherent variability on the profile of voltage and transient stability associated with wind power by placing different network contingences, fault locations and wind power output using static and dynamic methods respectively. Studies are conducted on a practically power system of some area in China.

The control of initial period rainwater plays an important role in urban water quality management since the initial period rainwater carries a greater portion of pollution loads. Appropriate strategies are needed for effectively controlling the non-point source loads (NPSL). In the present approach, the Storm Water Management Model (SWMM) is applied to simulate and control the NPSL of the service area of Chilong river pumping station in Tianjin city. At different rainfall intensity, the relationship between the interceptive amounts of initial runoff and their corresponding reduced portion of NPSL are obtained and the effectively controlling strategies are proposed.

It is very important to explore the feature bands of MODIS for retrieving the water constituent by remote sensing. This paper aims to use derivative spectrum and continuum removal to extract the feature bands of the water spectrum in Liaodong Gulf. By simulation of MODIS band using in situ field spectrum, we can avoid the impact of atmosphere on information extraction and can directly find the feature bands of MODIS. It is shown that the two signal processing methods of derivative spectrum and continuum removal can reveal the character of water spectrum. The result shows that the water spectrum of Liaodong Gulf has evident character of case 2 waters. It have two peaks and three thoughs. The feature bands of the water spectrum in Liaodong Gulf are located at 9,13,14,15 band of MODIS. They are the bands with the center wavelength of 442, 665, 677 and 746 nm respectively, which are due to the water constituents such as chlorophyll a and suspended sediment and so on. They reflect the character of waters in Liaodong Gulf, so they can be selected to establish the algorithms to retrieve water constituent with MODIS data by remote sensing.
