The overall design plan of Daqing gas company pipe network information system based on the way of Web is put forward and selecting Windows 2000 Professional as client computing operating system for running the ArcInfo 9.x application program and using other geographic information system software to build the geographic information development platform that gives priority to the ArcGIS of ESRI company.
According to the characteristics of system and combined with the practical work requirements, the overall design of system should obey the following basic principles: practical applicability, the application requirements of users can be satisfied, managed and maintained easily, which becomes a powerful tool which is able to be depended on; advance is the practical guarantee in the future, so the advanced technology, methods and equipments must be used as far as possibly and improve the technique level; safety and reliability, as a large-scale and key information system application [6], which is made up of many professions and departments are involved in practicing, safety and reliability is of vital importance; open and sharing which is the prerequisite and the enough guarantee for Daqing gas company pipe network geographic information system serves other corporate information systems and other network facilities in the city (water supply and drainage, power, telecom industry and so on)

With increasing concentration of carbon dioxide the amount of water vapor increases in the atmosphere and thus the relative humidity.

However, deformation of the dam is larger and larger with the height of CFRD increasing under the high water pressure after water storage.
Compression damage of face slabs occurred when the water level was close to the normal storage level in Brazil Barra Grande CFRD (dam height is 185m) [7].
The water level was 300m and the thickness of face slab is 0.3+0.0035H.

In addition, compared with traditional tidal power, the in-stream tidal power does not need to construct the dams, which greatly reduces the construction period and capital investment, and the resource comes from putting free stream turbines into fast water flows (as with wind turbines) rather than from a tidal barrage [5].Therefore, it raises a great interest in in-stream tidal energy technology in many countries and regions.
Such a device is equivalent to adding a Venturi tube in the external of the horizontal axis or vertical axis impeller, which makes the flow of water through the turbine more concentrated and have higher conversion efficiency[9]
Compared to the Horizontal axis turbine or Vertical axis turbine, Oscillating Hydrofoil technology can be arranged in relatively shallow waters of the unit, and have a wider field of applications than expected [4].

Then, fibroin fibers were rinsed three times with distilled water, dried at 600C and stored at room temperature.
FFs were obtained, washed twice with distilled water and dried at 600C.
It was insoluble in water but dissolved well in alkaline solution at high temperature.
Fibroin fiber was also insoluble in water but could be dissolved in mixture of salt/ethanol/H2O, lithium bromide [13, 19, 20].

Introduction Copper and Cadmium were two typical widespread heavy metal pollutants in natural water and soil [1, 2].
They were widely distributed in soil, sediment, aerosols, water and snow [6, 7].
The adsorption kinetics and isotherms of Cu2+ and Cd2+ on OCB were discussed and fitted by professional models.

Thus, the treatment of the effluent contained these compounds is important for the protection of natural waters.
Electrochemical technique uses a direct electric source between metal electrodes immersed in polluted water.
Dye solution was prepared by dissolving the dye in distilled water.

But In recent years a series of unfavorable problems turned up: supply and demand of water are inconsistent; resource consumption increases extremely; environmental pollution and ecological destruction are increasingly serious; economic structural is contradicted; economic growth is comparatively extensive and so on.
