In this paper, univariate or/and bivariate binormal model was established and its parametrers was estimated by the"method of scoring". To calculate the statistical significance of the difference between two ROC curves using any one of three distinct statistical tests: the bivariate Chi-square test, the area z-score test, and the TPR z-score test.

在第三章中，作为研究的出发点，我们首先考虑了半导体模型中的高维简化Euler-Poisson方程组(1.2.2)的柯西问题，当初值在平衡态附近扰动时，建立了该问题经典解的整体存在性，唯一性和指数稳定性。

There are three motheds generally: to seek equational solutions to analysis;to seek the numerical solutions of equtions; solutions\' qualitative analysis.

通常有三种方法：求出方程的解析解；求方程的数值解；对解的性态进行定性分析。

The first part of the whole, including: the main-scale displacement and the identification, map type, weight and general layout of calculating the focus of the plan is formally established; into the second performance, including: self-transformation and-line mapping, static water Calculation and static hydraulic curve, the stability of floating state calculation; third dip into the calculation; summed up into the fourth part, based on an evaluation of the design, lessons learned, the comprehensive knowledge.

We obtained an estimate of the third critical field for cylindrical superconductors, and proved that, as the applied magnetic field decreases from the third critical field, superconductivity nucleates first at the surface of the cylinder where the curvature is maximal; and also gave a mathematical theory to describe the surface superconducting state.

我们获得了柱状超导体第三临界场的估计，证明了当外磁场从第三临界场减弱时首先在柱面的曲率最大处出现超导性；给出了描述表面超导态的数学理论。

By comparison with responsive supply chain in three aspects,the paper brings to light that relativity advantage of RSC stems from the new industry paradigm ,and then puts forward it is the approach of improving the responsibility of ESC that remoulds ESC through the new industr.
