查询词典 equilibrium value

It is proved that, when the value of critical threshold less than 1, the disease free equilibrium point is globally asymptotically stable. Further more, Bursaphelenchtis Xylophilus is used to construct the Lyapunov function, and the stability theory of Lyapunov function is used to prove that the equilibrium point is Global asymptotic stable.

Some significative conclusions are founded out in the dissertation. The evolution of securities investor behaviors bears multi-equilibrium characteristics, namely, possibly converging to the equilibrium of complete value investment, or full noise trade, or coexistence of former two behaviors. And its evolution path and equilibrium are affected not only investor's payoff function and initial state of securities market, but expect error of noise traders, noise trade risk and so on.

通过研究发现，证券投资者行为的进化呈现出多重均衡的结构特征，既可能收敛于完全价值投资、也可能收敛于完全噪声交易、还可能收敛于价值投资和噪声交易共存的均衡点，而具体的路径选择和均衡不仅受到投资者的支付函数、证券市场初始状态的影响，而且与噪声交易者对风险资产收益的预测偏差、噪声交易者风险等因素有关。

The effects of solution\'s pH value, mol ratio between phenyl aldehyde and L-Arginine, concentrations of sodium chloride, ammonia chloride andL-Lystine, initial concentration of L-Arginine on precipitation rate of a -tolylene arginine were investigated, the results indicated that phenyl aldehyde precipitation method\'s appropriate pH value was higher than 11, suitable mol ratio between phenyl aldehyde and L-Arginine was 1.25, initial concentration of L-Arginine was must higher than 15g/L, sodium chloride had little effect on precipitation rate, on the contrary, ammonia chloride and L-Lystine had great effect on it, both of them must be eliminated; At the same time, adsorption isotherm at 25 C of L-Lystine on anion exchange resin A was measured, the result showed that the maximal equilibrium adsorbance was 30mg/g, the influences of solution\'s pH value, temperature, concentration of chloride ion on adsorption of L-Lystine by anion exchange resin A were also studied, the results indicated that appropriate operational pH value was 0.5 0.2, the effect of temperature on adsorption ratio was little, process could be operated at room temperature, the concentration of chloride ion must be eliminated.
