The structure and stability of all possible isomers of C50X(X=SiH2, PH, S) were investigated by ab initio HF/3-21G calculations. The calculation results indicate that the preferred position for cycloaddition of SiH2, PH, and S on C50 is consistent, i.e. on the C3-C4 and C4-C4 sites of C50, and the resultant most stable cycloaddition isomers are [5,6]-closed and [5,5]-closed structures. The main driving force governing the stability of the C50X(X=SiH2, PH, S) isomers is the strain, or the conjugative effect, or the combination of strain and conjugative effect, depending on the addition positions and the types of the attacked C-C bonds.

用从头算HF/3-21G方法研究了C50的环加成衍生物C50X(X=SiH2， PH， S)所有可能的异构体的结构与稳定性，计算结果表明，SiH2基团、PH基团与S原子在C50上环加成的优先加成位置相同，都为C3-C4类键和C4-C4类键，并且相应形成[5，6]-闭环和[5，5]-闭环结构的最稳定异构体；决定C50X(X=SiH2，PH，S)各异构体稳定性的主要因素，因加成位置以及发生加成反应的C-C键的单双键类型的不同，可能是张力、共轭效应或者二者的共同作用。

Three components of peroxide in the activator amongwhich have the different decomposed temperatures made the Vinyl-ester resinsolidified heat discharge increased that gained a bigger solidified degree. Theactivator-adopted quantity can dramatically affect the casting samples performance:eg. When use 1.0-1.4 portions of activator, the casing sample can reach its maximumTensile strength and Bend strength; when use more activator, the polymeric meshworkcontracted which embrittle the casing sample and reduce the dynamic performance; Inthe Pultrusion processing, when CF composed of about 60vo1%, more demould agentcan bring the better processing but degrade the CFRP, normally use around 1.2 portion.

采用具有不同分解温度的三组分有机过氧化物引发剂，乙烯基酯树脂的固化反应放热量增加，固化程度提高；引发剂用量对浇注体的性能影响很大，在用量为 1.0~1.4 份时，浇注体拉伸强度剂弯曲强度达到最高，过多的引发剂使聚合网络减小，浇注体变脆，力学性能降低；在拉挤成型工艺中，碳纤维的体积含量一般为 60%左右，脱模剂增加使加工性能好转但会使复合材料性能下降，一般用量为 1.2 份。

Furthermore, the one-dimensional complexes 26 and 28 with strongπ-πpacking interactions are prepared from DMF solvent, which indicates that the traditional solvent volatilizing method could bring low-dimensional complex.4. By measuring the enthalpy changes of the liquid phase formation reaction for complexes a~e, and calculating the electronic densities of five 5-substituted derivation of isophthalic acid, we can make a conclusion that 5-substituted group changing of the ligand has a little influence on oxygen atoms of carboxyl groups.5. Fluorescence experiments of these complexes indicated that they could be used for luminescence materials in future.6. Using packing saturation rule we calculated and analyzed these series of complexes, and the results showed that the changes of complexes with changes of ligands could be explained from the rule.
