Stressing on "fine reputation","quality","service","credit","practice", not only the grandeur.④Encouraging the innovation, not the unearthliness, playing down the effect of entertainment stars or idols, decreasing the fashion index.⑤"personality" is not the "self central". Social sense of responsibility and interpersonal "feeling of affinity" are both intensified.3.1.2 Factor analysis, revealing 19 value element vectors, which include "comfort","personality","simple","fine reputation","responsibility","service","price","wisdom","distinction","enthusiasm","stimulation","taste","sex difference","quality","vigor","idol","fashion","affinity","aesthetic" and so on. Four orientation diagrams coordinated with the average factors and the standard deviations of these 19 value elements, described the multi directional value orientation structure for China college students' sportswear consumption.3.1.3 Clustering analysis are applied to classify the former 19 value elements, which discovered that three inferior group are classified from the college students' consumption group based on the whole specimen data. It could be the reference of enterprise brand building for the orientation of consumption values.3.2 General personal values, self conception and demographic are lead into as three major variables for the interrelationship analysis of sportswear consumption value system.3.2.1 Firstly, the college students having their general values and existing the inferior group feature regarding to the consumption values.
三、研究的主要成果及其意义对中国大学生休闲服消费价值体系进行探索性分析1、首先对中国大学生休闲服消费价值观量化问卷所调查的样本数据进行频数统计趋向性分析,发现呈现的主要特点有:(1)"个性化"和"简约"已成为潮流,而寻"刺激"、找"激情"总体收敛;(2)追求"美感",更不放弃"舒适",两者兼得才是完美;(3)重"美誉"、讲"质量",重"服务"、讲"信用",求实际、不求高贵,"明智"有素;(4)求新不求怪异,明星、偶像效应淡化、时尚指数不高;(5)"个性化"不是"唯我化",社会责任感和人际"亲和力"在强化。2、其次对样本数据进行因子分析,揭示出以"舒适"、"个性"、"简约"、"美誉"、"责任"、"服务"、"价格"、"明智"、"独特"、"激情"、"刺激"、"品位"、"性差"、"质量"、"活力"、"偶像"、"时尚"、"亲和"和"美感"等十九个价值元素为矢量的休闲服消费价值体系,并以因子均值和标准差为参数勾画出19个价值元素坐标四方位图,从总体上描述了中国大学生休闲服消费多维的价值取向结构。3、再者进行聚类分析,对上述十九个休闲服消费价值元素作不同量值的分类,发现在样本总量中可以细分为有较大区分度的三个类别,呈现出大学生消费群体中存在休闲服消费价值体系不同的亚群体,可为以消费价值观为取向的企业品牌价值定位提供参考基谱。

When processing the restrained conditions, we convert the restrained conditions into punish function and add it to fitness function which profits from the conventional method. We introduce the support vector machine to the selection operator, which increases the multiplicity of selection and increases the probability of the algorithm getting the overall optimal solution. Also, we use the adaptive probabilities of crossover and mutation in mixed GAs which enhances the efficiency of the algorithm. The result of tests about the system indicates that the improved genetic algorithm has more high convergence speed and better solution quality.
在生成初始种群时,不是简单的随机生成,而是用支持向量机对历史数据进行分类,用较优的一类历史数据作为初始种群;在约束条件的处理上,本文借鉴常规方法中的罚函数法,采用将约束条件作为罚函数包含到适应度评价中去的方法;在选择算子上,本文引入了支持向量机的方法,增加了选择的多样性,增加算法搜索到全局最优解的概率;同时针对交叉概率和变异概率在算法的前后期不同的情况,本文引入了Srinvivas等提出的动态自适应的方法,使得交叉概率和变异概率能够随着算法中个体的质量动态改变,提高算法的效率。

Results: The changes following hydrocortisone intervention of rats could be identified by PCA, and the kidney deficiency syndrome rats entered a state of "hyperfunction", involving a series of changes in metabolic pathway and metabolic network. The response integral area of lactic acid (δ 1.37) increased, indicating the accumulation of metabolites of lactic acid. The amount of dimethylamine (δ 2.72) also increased, indicating that the disorder of kidney function was related to kidney-deficiency syndrome. The response of creatinine (δ 3.87), asparaginic acid (δ 2.83), taurine (δ 3.44, 3.28), and hippurate (δ 7.84, 7.56, 7.64, 3.97) all decreased significantly, indicating that the hydrocortisone might cause adrenal cortex excretion injury. The response integral area of succinate (δ 2.41) and citric acid (δ 2.53, 2.68) decreased, which was usually caused by disorder of the mitochondrial function.
结果:PCA方法处理肾虚证和空白对照大鼠尿液数据显示,两组大鼠的数据可以在得分图实现分类,与对照组比较肾虚组大鼠由于氢化可的松诱导,大鼠机体进入一个过消耗后衰弱的状态,相关代谢发生显著变化,乳酸(δ 1.37)代谢发生堆积;二甲胺(δ 2.72)的含量增加,提示肾虚与肾功能异常是密切相关的;天冬氨酸(δ 2.83),牛磺酸(δ 3.44, 3.25),马尿酸(δ 7.84, 7.56, 7.64, 3.97),肌氨酸(δ 3.87)等的相对积分面积明显下降,这预示糖皮质激素可能引起了肾上腺皮质分泌功能的损害;琥珀酸(δ 2.41)和柠檬酸(δ 2.53, 2.68)是三羧酸循环能量代谢及糖酵解的中间产物,其含量的降低,通常是由于线粒体功能紊乱所引起。

Cooperating the advantages of SVM solve classification problems about small sample set, non-linear and multi-dimension model identification, I use SVM to train the sample set of different frequency signal and look for a super plane to divide the data into two parts. This method gets rid of complex computation which is a flaw of traditional decoding method.This paper introduces the theory and algorithm of SVM at first. It proposes to use the SVM to decode FSK signal based on the classifiable character of SVM.
