Consequently, we can deduce factors affecting company's growth rate through WACC formula during terminal growth period. Then the company's terminal value growth rate in steady growing period can be obtained by analyzing these factors. Our result shows Chinese company's terminal value growth rate in steady growing period is 3%-5%.

The gasification efficiency increased and the molar fraction of H2 decreased with an increase in the reaction temperature. The decomposition of PVA was more complete at higher temperatures. At 24 MPa, 500℃ and 120 s, the TOC remove rate, the carbon gasification rate and the hydrogen gasification rate were up to 71.46%, 67.97% and 157.24% respectively. A change in the residence time had no significant effect on the molar fraction of gas production but an increase in the residence time could enhance the gasification efficiency of PVA. It was found that the intermediates were mainly alkane, cycloparaffin, aromatic hydrocarbons, and low-molecular weight acids. It was supposed that PVA was degraded into small molecules through breaking of C-C bonds. Parts of the molecules were converted into H2, CO, CH4 and CO2 while some was converted into aromatic hydrocarbons.

过程探索发现:反应温度的升高能提高PVA气化效率,但气体产物中H2的含量随反应温度的升高有所下降;随着反应温度的升高,PVA分解趋于彻底,在压力24MPa、温度500℃、停留时间120s的条件下,TOC去除率、有机碳气化率和氢气化率分别达到71.46%,67.97%和157.24%;停留时间的变化对气体产物含量没有明显的影响,但延长停留时间能提高PVA的气化效率;PVA气化反应中间产物主要为链状烷烃、环烷烃、芳香烃及小分子酸,根据中间产物出现的顺序推测PVA的降解为由C-C键断裂形成小分子物质,这些小分子物质一部分转化为H2,CO,CH4和CO2,一部分形成难降解的芳香族化合物。

Chapter six presents such new concepts as margin utility contribution force, profit-risk exchange rate, state-expectation-variance utility function, long-term expectation-variance utility curve and optimal portfolio expansion curve. The state-expectation-variance analytical method is developed from the expectation-variance analytical method. The changing rate of profit-risk exchange rate to state variable is used to define and distinguish the decreasing, constant and increasing relative risk aversion. A decomposition formula about the margin contribution force of holding wealth to state-expectation-variance utility function is displayed. The decomposition formula demonstrates that the contribution force of investors' holding wealth to their utility is composed of the pure contribution force of holding wealth and the investment contribution force bronght about through investment portfolio.

Study result suggest: The change of stock in RFCCU directly affect gasoline content. Gasoline content can be reduced through increasing the equilibrium activity of catalyst, controlling reaction level, increasing recirculating rate of gasoline and stability of gasoline level. Conclusions drawn from experiment is that optimization of operating condition has great effect on lowering olefine content of gasoline which can be reduced from 60% to 50%.Reducing reaction temperature is useful for lowering olefine content of gasoline, when the reaction temperature is raised, thermal cracking rate is higher than catalytic cracking rate, so that olefine content is increased. Raising catalyst-to-oil ratio is good for lowering olefine content. With conversion rate increased, the yield of LPG and coke is raised, the yield of gasoline is increased firstly and then decreased slightly, hydrogen transfer index is increased, so the olefine content is decreased.
