Thus, evaluation of the minimum zone circle could be solved effectively.Three methods of assessment of roundness error were proposed in this dissertation. Based on the criteria of the minimum zone circle, minimum circumscribed circle and maximum inscribed circle and convex hull, a unified approach was proposed to evaluate roundness error of the minimum zone circle, minimum circumscribed circle and maximum inscribed circle. Evaluation of the minimum zone circle, minimum circumscribed circle and maximum inscribed circle was fulfilled with rotation based the contact pattern. The minimum circumscribed circle and maximum inscribed circle were evaluated with curvature and the curvature circle.

First, this article introduced 2 grade of rotary kiln principle of work and the equipment, to rolled the circle mechanics behavior to carry on the analysis, proposed - rolled the circle - under roller's rotary kiln overall modelling based on the tube body - kiln liner - big tooth ring, to rolled the circle - under roller's contact stress to carry on the finite element analysis the method, and obtained rolled the circle contact stress the size and the distribution rule, finally indicated that rolled the circle contact stress mainly to have two main peak values and the sudden change in one week, appeared is rolling the circle and the under roller contact area; Then, rolls the circle the stress to regard as is the principal stress unknown plane stress test, the use quite mature modern test technology, proposed rolls the circle stress test the principle and the plan, and to rolled the circle the stress to carry on the scene test, the stress which the scene test analysis result and the finite element analysis calculated has compared, had proven the whole method modelling's finite element analysis method's rationality and rolled the circle - under roller contact stress the result accuracy; Finally, uses ANSYS APDL the re-development technology, in view of 2 grades of rotary kilns, rolled the circle - under roller contact stress the overall finite element analytic method to carry on the re-development.

首先，本文介绍了2档回转窑工作原理和装置，对滚圈的力学行为进行了分析，提出了基于筒体-窑衬-大齿圈-滚圈-托轮的回转窑整体建模，对滚圈-托轮的接触应力进行有限元分析的方法，并得到了滚圈接触应力的大小和分布规律，结果表明滚圈接触应力在一周内主要存在两个主要的峰值和突变，都出现在滚圈与托轮接触区域；然后，把滚圈的受力看成是主应力未知的平面应力的测试，利用比较成熟的现代测试技术，提出了滚圈应力测试的原理和方案，并对滚圈的应力进行了现场测试，现场测试分析结果与有限元分析计算出的应力相比较，证明了整体法建模的有限元分析方法的合理性和滚圈-托轮接触应力的结果的正确性；最后，利用ANSYS的APDL的二次开发技术，针对2档回转窑，就滚圈-托轮接触应力的整体有限元分析法进行了二次开发。

第四，基于经济增长收敛的理论与方法，对江苏省区域经济发展的收敛性进行了研究。1978一2000年，江苏省人均GDP总体上不存在u一收敛；农民人均纯收入增长在1 984一1993年及1999年以后不存在a一收敛、在1993一1999期间存在a一收敛；1978-2 000年，人均GDP增长总体上不存在绝对p一收敛，但存在条件p一收敛，收敛的程度较弱，半生命周期比较长，落后区域要缩小与发达区域经济差异的一半最少也需要115年；1 994一2000年，在经济比较发达的苏南和苏中内部存在俱乐部收敛，在苏北内部不存在俱乐部收敛趋势。

Yangtze Delta Urban Economic Circle, Zhujiang Delta Urban Economic Circle, Beijing-Tianjin-Hebei Urban Economic Circle, Chengdu-Chongqing Urban Economic Circle, and Wuhan Urban Economic Circle are five important urban economic circles, among which, four economic circles except Wuhan Urban Economic Circle have club convergence phenomenon and this club convergence is greatly related to industrialization degree, inner economic structure and innovative ability of the five economic circles.

The main conclusions of this chapter are the following: There is no absolute regional convergence since 1978, even the period were divided into two stage: 1978-1991 and 1992-2002; There exists absolute convergence among the provinces in eastern region in the period 1978-1991, the phenomena is alike to the central and western regions, so the club convergence is the fact of the regional economic growth in this stage; From 1992 to 2002, instead of the club convergence, there exists conditional convergence, human capital, capital investment, international trade and FDI influenced the regional economic growth rate markedly; The distribution of income across provinces don't transform from a unimodal into a bimodal distribution.

本章的基本结论是：改革开放以来不存在绝对收敛，即使将整个改革时期划分为1978—1991年和1992—2002年两个区间也是如此；1978—1991年期间，东部地区和中西部地区内部各自存在人均GDP和劳均GDP增长的收敛，从而形成了俱乐部收敛；1992年之后，并不存在俱乐部收敛，但存在一定的条件收敛，人力资本、物质资本投资、国际贸易和FDI对劳均GDP增长有着重要的正向影响；收入分布并没有发生由单峰向双峰分布的转变，总体上单峰的态势依然十分明显。
