Ideal wound dressing increasing wound healing process, inhibit infection of microorganism, revitalize structure and function of skin.
PolyvinylPyrrolidone (PVP) with MW 1,300,000 g/mol and 2,2-Diphenyl-1-picrylhydrazyl (DPPH) were manufactured from Aldrich Chemistry.

Because the mountain tunnel structure is designed based on the action of collective drainage system without influence of groundwater pressure on lining, so when the failure of collective drainage system happens, the harmful deformation will be produced in lining concrete by large hydraulic pressure.
Using short- and long-term transients in seepage discharge and chemistry in a mountain tunnel to quantify fracture and matrix water fluxes,Journal of Hydrology,2000, 23(4) : pp142-161 [2] JTG D70-2004.Specifications for Design of Highway Tunnel, People’s Communication Press,2004

The contradiction between obtaining the spider fiber efficiency and raising spider hardly has attracted attention in various research fields such as life science, chemistry, material and so on.
The chemical composition, molecular constitution and the state of aggregation structure of spider fibers have been reported in many studies [5-8].

In the particular seawater intrusion area, the establishment of relationship between Cl- content in groundwater and groundwater level is based on the full understanding of the strata, lithology, geological structure, the degree of karts development and exploitation of nature as well as the degree of groundwater development and combined with the dynamic monitoring data of groundwater.
The key job is establishment of the groundwater dynamic monitoring network in coastal areas, to monitor the water level, water chemistry, and marine hydrological when necessary.

However, it is today being widely studied because of its unique properties, which are a result of its fascinating structure.
