In this implementation, the evolutionary algorithm is hybridized with the simulated annealing algorithm and the hill climbing heuristic. The main aspects are as follows. The Metropolis criterion of the simulated annealing algorithm is introduced to select the offspring in order to make the algorithm more effective to escape the local optimum. In terms of the hill climbing heuristic, the local normal perturbing mutation operator based probability selecting is developed to enhance the local searching of the algorithm.

其主要工作是将进化算法与模拟退火算法及爬山方法相组合，引入模拟退火算法中Metropolis接受准则选择子代，提高算法跳出局部最优解的能力：借鉴爬山方法思想，构造了基于概率选择的局部正态摄动变异算子，以强化进化算法局部细搜索能力；同时进化算法以多种群方式实现，在降低计算时间的同时提高算法收敛到全局最优解的概率。

The question of searching characteristic points or straight lines on moving rigid body is decomposed into two relatively independent sub-questions. The first one is to evaluate the characteristic of points and straight lines on moving rigid body, whose mathematics model is a kind of special non-differential max-mini optimal problem with inequality constraints. By the method of Saddle-point Programming and maximum entropy, the problem can be transformed as a differential optimal problem with single objective. The second oner is to search approximative character points or straight lines on moving rigid body within design space, whose mathematic model is nonlinear and non-differential problem with multiple constraints.

本文将在运动刚体上寻找特征点或直线的优化问题分解为两个相对独立的子问题，一是对运动刚体上点或直线的特征性评定，其实质是平面曲线的圆度或直线度的评定问题，优化模型是以最大误差为最小作为优化目标的约束不可微的优化问题，本文采用鞍点规划和极大熵方法，将其转化为单目标可微优化模型；二是在设计空间内，寻找运动刚体上特征性评定指标最小的近似特征点或直线，其优化模型是非线性、多约束的不可微优化问题，本文提出用遗传算法和BFGS局部搜索法相结合来求解。

Patients with COPD have similar change of VC and its componentsas the normal subjects after breathing heliox,but the increased rate of ERV is much higher,and this is possibly due Objective:To the chronic overexpansion of pulmonary alveolus.The decreased rate of IC is smaller in COPD patients than that in the normal subjects.

结论COPD患者呼吸He-O2后VC及其组成有健康人相类似的反应，不同的是ERV的增幅比率较健康人要大得多，这可能与COPD肺泡长期处于膨胀状态有关，但IC的减少率又比健康人要小，呼吸He-O2后IC何以会减少以及COPD组与对照组间的变化率何以存在显著差异？
