From the mainstream of old channel to saline water area of interchannel belt, groundwater hydro-chemistry type by HCO3- evolves into the Cl.SO4 -Mg.Na.Ca type and Cl.SO4-Na.Mg.Ca type gradually.Thus, improving measures such as pumping saline water in non-flood season and treating water with reverse osmosis material and so on are put forward to make the saline water evolve into fresh water.
The lithology of aquifer is mainly composed by fine sand and silt with thin multilayer structure vertically.
Besides, saline water is rich in free CO2 of 48.95 mg/L,which accelerate the dissolution of halite further,resulting mean of salinity being 11883.69 mg/L.From the mainstream of old channel to saline water area of interchannel belt, the groundwater hydro-chemistry type by HCO3- evolves into the Cl.SO4 -Mg.Na.Ca type and Cl.SO4-Na.Mg.Ca type gradually,which is consistent with its changes of salinity.
From the mainstream of old channel to saline water area of interchannel belt, the groundwater hydro-chemistry type by HCO3- evolves into the Cl.SO4 -Mg.Na.Ca type and Cl.SO4-Na.Mg.Ca type gradually because of hydro-geochemistry function such as adsorption ,CEC,mineralization and so on .Salinity and total hardness is also increased .The water salinization trend is more obvious.

Neutrons and accelerated ions can be used to transmute constituents of a solid sample and thus provide analytical chemical information as well as being used as scattering probes of structure.
To this end a symposium and tutorial workshop on MODERN NUCLEAR METHODS IN MA TERIALS SCIENCE was held in Washington D.C. in conjunction with the Fall 1983 Meeting of the American Chemical Society, and which was jointly sponsored by the Division of Nuclear Chemistry and Technology and the Division of Physical Chemistry.

The complex formed one dimensional chain structure through intramolecule and intermolecule hydrogen bonds.
The structure was solved by direct methods and refined by full-matrix least-squares techniques on F2.
The structure was solved by direct methods using SHELXL-97 [7] and expanded using Fourier techniques.

The thiols structure breaks at this time and regain its activity slightly higher after certain period.
