Based on the principles of autocatalysis and the theory of entropy, this paper tries to discuss and attest the autocatalytic mechanism in systems which cause general S curve.

运用熵理论和自催化原理对系统发展过程中普遍存在的 S型曲线的成因进行了论述和证明，指出系统出现 S型发展曲线是由系统的自催化机制和系统的限制因素共同作用引取。

Secondly, a series of computer programs have been developed and verified according to the deterministic chaos theory and algorithms. These programs are deterministic chaos qualitative analysis tools including phase plots and Poincare section analysis software packages; deterministic chaos quantitative analysis tools including the largest Lyapunov exponent, correlation dimension and Kolmogorov entropy analysis codes and classical analysis such as power spectrum, autocorrelation coefficient and Hurst analysis programs.

Based on information entropy and mutual information, we proposed the definition of nonlinear partial autocorrelation.

本文在信息熵和互信息的基础上，提出了非线性偏自相关的定义。

1、The Entropy、Smoothness、Uniformity and Relation (base on co-occurrence)are significantly difference between the patients and volunteers(p.05).2、The Contrast (base on co-occurrence matrices) and Distance (based on autocovariance coefficients) tend to be higher volunteers, but not reaching statistical significance.3、Among all the thirty-nine features, the most significant difference was obtained using Relation with the pixel distance varied from 1 to 3 pixels.

本实验使用纹理分析的方法研究正常膀胱壁组织和膀胱赘生物组织的纹理特征，并筛选出四种存在显著统计学差异的纹理特征，为后续利用纹理特征研究膀胱肿瘤浸润肌层深度提供了依据。另外，如前所述，目前膀胱肿瘤的诊断主要依靠膀胱镜，但作为一种侵入性操作，膀胱镜并不适合人群疾病普查和患者的治疗后随访。

We propose a model-calibrated K-L relative entropy minimization approach to using complete auxiliary information from survey data.

本文我们提出了使用调查数据中完全辅助信息的模型校正K-L相对熵最小化方法。
