The study of lattice-valued propositional logic system based on lattice implication algebra.On the bases of previous study, by using the concepts and methods of T algebras we established the lattice-valued propositional logic system LP , whose truth values domain is a lattice implication algebra, and discussed systematically the semantical and syntactical properties of LP , proved the soundness theorem 、consistency theorem、deduction theorem and the decidability of validity of the system when the truth values lattice is finite. We also discussed the relationship between the α-theorem of some premise, say A, and the closed sets that contain A.

Empirical evidence in this paper shows that the price of A shares in Shanghai and Shenzhen Stock market is inconstant with the random walk model, and that low-dimension deterministic chaos process are found in the time series of Shanghai A shares index with a Correlation Dimension of 1.4, which means that the degree of randomness is lower than that of grown-up capital markets, and so the lower of the efficiency degree to some extent.

本论文所做的实证研究表明，沪深A股市场价格并不呈随机行走状态，而是存在非线性结构；上海A股市场指数收益率序列存在低维确定性混沌过程，其维数大约为1.4，这一数值远低于成熟资本市场的指标，这表明上海股票市场指数收益率序列随机性低于成熟资本市场。
