However, the spectral stability was increased, and the 0-1 transition and the full width at the half-maximum of photoluminescence spectra was decreased with the increase of the alkoxy length on phenylene. The nature (e.g. electron-donating and electron-withdrawing) of the substituted side groups on phenylene has obvious effect on the optical properties, QY and electrochemical properties of the polymers.

苯环上取代侧基的给吸电子性质变化对聚合物的光电性能具有全面的影响，改变取代侧基的给吸电子性质可调节芴苯共聚物的发光颜色和HOMO、LUMO能级以及HOMO-LUMO能隙等，因此，通过引入不同性质的侧基可以实现对此类聚合物光物理性能的调控。

According to alternation of reorganized-KMT "s class nature what the Comintern and Sdalin defined and KMT "s authentic class nature, we"ll find the inner coincidence between the three, KMT "s class nature what the Comintern defined, Sdalin"s "Three Stages Theory" and errors of "Left deviation in the Agrarian Revolutionary War. They have the same fault: on the theory of Chinese bourgeoisie. Comintern looked on Kuomintang as an organzation of united front, which cut apart the close relationship between Kuomintang and the boureoisie, and then inevitably led to a long-standing mistaken concept, this is, confusing the large boureoisie with the national boureoisie and the petty boureoisie. Therefore, as the large boureoisie betrayed the revolution, Comintern regarded the national boureoisie and the petty boureoisie as the underminer of the organzation of the united front, and then struck a heavy blow at then.

考察梳理共产国际、斯大林对改组后国民党性质的判定及其变化和国民党的真实阶级性质可知，共产国际对国民党性质的判定、斯大林"三阶段"论和土地革命战争时期中共党内的历次"左"倾错误三者之间，前后相续，一以贯之，具有内容上的共通性和逻辑上的连续性，它们共同的要害是共产国际、斯大林有关中国资产阶级理论的错误，一是共产国际混淆在半封建半殖民地中国的带买办性的大资产阶级与民族资产阶级，二是把民族资产阶级的妥协与革命的两面性机械地认定为革命与反革命的"两段性"，认为中国资产阶级必然要叛变革命。

Through analyzing the research result of four series studies, we conclude that the description about toplogical perception that is prior to the perception of local featural properties does not fit to the visual perception, and the figure visual perception is not affected by the different geometrical levels, and the relative perceptual salience of different geometrical properities is not consistent with the hierarchy of geometries according to Kleins Erlangen Program.

Through analysis, the thesis thinks that the economical nature of environment goods cannot be generalized by public goods or private goods, its nature has been changing between the two extremes. The environment goods is on one hand reflected in some legal arrangement in international environment statute, where the focus is the whole humankind, for example,"common heritage"; on the other hand, it is also reflected in the rules that protecting private rights in civil legal system, where the focus is the individual, for example,"the right of environment personality ". The essential part of environment justice is the social distribution of environment benefits and burdens, so the thesis centers on the social peculiarities of environment goods as social burdens and as social benefits. In detail, environment benefits are related both to property and to personality, and they are also un-produced, non-substitutive and prima goods as living resources; environment burdens are composed of LULUs and many uncertain and irreversible environment risks.

通过分析，本文认为环境物品的经济性质不能单纯地用公共物品或私人物品进行概括，其性质在此两极之间会发生变动；而法律构造中的环境物品一方面体现在国际环境法中的主要以&类&为主体的各种制度安排中，例如&人类共同遗产&，另一方面则体现在民法体系中以&个人&为主体的各种私权保护的规则中，如环境人格权等；接下来，鉴于环境正义的核心是环境利益与负担的社会分配，所以本文重点探讨了作为一种利益和作为一种负担存在的环境物品的各种独特的社会属性，具体而言，环境利益具有财产属性、人格属性、非制造性、不可替代性以及作为生存资源的前提性；而环境负担则具体包括&不可欲的局域性土地利用方式&和具有科学不确定性和不可逆性的环境风险。
