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。

Because the time series generated from finite difference equation with chaos may also possess exponential distribution of probability density. Additionally, irregular dynamics has ever been attributed to the presence of stochastic noise in many systems, but actually it may result from chaotic process in deterministic system.

近年来对非线性动力系统的深入研究发现:观察到某一过程具有指数型概率密度事件分布并不足以确定它就是泊松过程,由具有混沌行为的有限差分方程所产生的时间序列也可具有指数型概率密度分布;在许多系统中,过去归因于随机噪声的不规则动力学特性,实际上很有可能是由确定性系统中的混沌过程所致。

The left ventricular internal dimension at end diastole, interventricular septal thickness at end diastole and left ventricular posterior wall thickness at end diastole were measured in the parastemal long axis view by transthoracic two-dimensional echocardiography, and to calculate left ventricular ejection fraction with Teichholtz formula and left ventricular mass with modified Devereux formula, left ventricular mass index=LVM/body surface area. From the apical four chamber and two chamber view, the basical segment and middle segment of interventricular septal, left ventricular lateral wall, anterior wall and inferior wall were obtained by tissue Doppler imaging, Regional left ventricular relaxation asynchrony index was calculated.
