In analytical chemistry, the QSAR/QSPR method is usually used in chromatographic retention values and the prediction of behavior in capillary electrophoresis.
In the field of pharmaceutical chemistry, QSAR/QSAR predicts the activity of new chemicals and guide drug synthesis through the study of the correlation between the biological activity and structure parameters.
Biology, chemistry, mathematics, computer graphics theory science and other related science development will prompt QSAR study from description to reasoning, from qualitative to quantitative, and from macroscopic to microcosmic structure of state development.

But the phase of the SrFe1.25Co0.5O3-δ powder maintains unchanged behaving good phase stability and chemistry stability.
However, another kind of SrFexCo0.5O3-δ powder with the Fe content of x=1.25 mainly consists of browmillerite structure and a small amount of perovskite structure.
However, the phase of the SrFe1.25Co0.5O3-δ powder maintains unchanged behaving good phase stability and chemistry stability.
The phase transition from ordered brownmillerite structure to disorder perovskite structure is strongly dependent on the content of Fe of the SrFexCo0.5O3-δ powders.

The influence on surface characteristics of microalgae cell have been studied by the solution chemistry condition of pH and cationic flocculant.
But the relationship between the surface characteristics of microalgae and the solution chemistry condition of pH, cationic flocculant and so on is not researched.
This is may be due to the structure of cells and extracellular products.
It’s relationship with the cell structure and extracellular secretion under different pH condition.
It attains the lowest when pH is about 8 from the tend curve. 0 10 20 30 40 50 60 70 3 5 7 9 11 13 pH Hydrophobicity / % Fig. 3 Effects of pH on hydrophobicity of microalgae cells Fig. 4 Morphology of microalgae cells in different pH value The change between CSH and pH is relevant to the cell structure and extracellular products.
