Based on the IPAT identity and using the economic, social and statistical data, this article selects STIRPAT model to create China's driving factors model of carbon emission. With the method of scenario analysis through the model, we predict under the base scenario, the energy saving scenario, the economic structure optimization scenario, the economic structure optimization scenario and the multiple...
The response surface methodology (RSM) was employed to optimize the process parameters of supercritical carbon dioxide extraction of the oil from caculis of Schisandra Chinensis(Turcz.) Baill. The effects of temperature, pressure and flow rate on the oil yield were investigated. Results showed that the data were adequately fitted into the second-order polynomial model. The linear and quadratic of...
