By the morphological analysis of the phosphorus in the main surface water and sediment in Jingzhou Prefecture,the paper have announced the distribution characteristic of different shapes phosphorus in the surface water and sediment.

Morphological analysis and synthesis have been done to the configurations of the clouble arm link die-clamping mechanisms with 5 pin joints which are currently used in plastic inzection machines.

According to the need for determining the respective state parameters under zero state,morphological analysis problems are divided into three categories,i.

Speciation analysis and determination of As in soil;

Application of crown ether crosslinked chitosan for arsenic speciation analysis;

Studies and prospect on the speciation analysis of chromium;

A review of the application to species analysis of arsenic was presented of coupling techniques such as high performance liquid chromatography coupled separately atomic fluorescen of Ocean spectrometry,atomic absorption spectrometry,mass spectrometry et al,and then much attention was given to the methods of deposition and pretreatment techniques.

This paper used the atomic fluorescence spectrometry to study arsenic species analysis and determine organic arsenic and inorganic arsenic in three species of alga.
