At last, we continue to analyze the influence which the macroeconomic growth rate has on the volatility of the stock returns. We make the macroeconomic growth rate as an exogenous variable to add to the above iterated weighted volatility model. From the above analysis, we can draw a conclusion that the volatility of the stock returns of Chinese stock markets will strengthen in economic expansion period and weaken in economic recession period.

The temperature effect on the oil yield was discussed at first. Then, analytical work was carried out as follows: the ultimate analysis and physi-chemical analysis of the pyrolytic oil comprised a sketch of the fuel properties of the oil; Then, through the distillation analysis of the oil, the fraction composition of the "unrefined"oil was known. After that, a general knowledge of the aromaticity and saturation of the hydrocarbons in the oil was provided by the outcome of the FT-IR functional group analysis. Also, from the analysis, the form of the polar functional groups and their distribution in different fractions of the oil were learned.
