The main results are as follows.1. The UV-visible absorption spectra, the spin-trapping EPR measurements, and the DPA (9,10-diphenylanthracene) bleaching experiments showed that (1) HB-Net exhibits much improved light harvesting efficiency in the phototherapeutic window (600-900 nm) as the result of its remarkable absorption red shift with respect to HB;(2) HB-Net remains the generation abilities of semiquinone anion radical, superoxide anion radical, hydroxyl radical, and singlet oxygen, but with much lower efficiencies than that of HB, most likely due to its very short triplet excited state lifetime.

设计合成了寡聚吡咯酰胺修饰的竹红菌乙素衍生物HB-Net，利用紫外-可见吸收光谱、自旋捕获技术和DPA光漂白法详尽比较了HB-Net与HB的光动力性质，发现：(1) HB-Net的吸收光谱较HB有显著红移，在光疗窗口的吸光能力明显提高；(2) HB-Net能够产生半醌负离子自由基、超氧负离子自由基、羟基自由基和单重态氧，但由于其短的三重态寿命，这些活性物种的产生能力均弱于HB.2。

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。
