heological properties at a low shear rate range(10-2-10s-1) and the glass transition temperatures for PEK-C with different moleCular weithts have been studied by using a cone/plate rheometer and DSC'The activation energy for melt flow increases with Mw The dependence of Tg on molecular weight exhibits two linear range and the value of nitersect agrees with the critical molecular weight, Mc'which is first reported for PEK-C'Mc value obtained according to η0 is about 8× 104 g/mol and the relation between Mc and temperature was dis-cussed.
用锥权流变仪及DSC的方法研究了5种不同分子量的酞侧基聚芳醚酮在低剪切速率区（10－2－10s－1）的流变行为及其分子量与玻璃化转变温度的关系。结果表明，样品的粘流活化能随分子量的增加而增大，Tg随分子量的变化是二个线性区，其交点值与所求的样品的临界分子量值相对应。利用测得的零剪切粘度值（η0）首次求得了PEK—C的临界分子量值。同时也讨论了Mc与温度及η0和Tg与分子量的关系。

High temperature contrast test: Conducting this compared test under the temperature of 450℃ with rubber cable, fluorin cable, TPU cable and PEK
高温对比试验：与硅橡胶电缆、氟塑料线、聚醚醚酮线、聚酰亚胺线在450℃温度下进行高温对比试验。
The XRD curves indicated Sm3+ ions could distribute homogeneously within the polymer matrix due to the formation of coordination bonds between Sm3+ and the carboxyl groups of PEK. The fluorescence spectra showed that all the coordination polymers obtained could exhibit the intense characteristic emission of Sm3+ ions under UV excitation.
采用荧光激发和发射光谱对制备的配位聚合物的荧光性能进行了研究，结果表明这些配位聚合物在紫外光激发下均能够发射出较强的Sm3+的特征荧光，且因刚性PEK高分子链的引入配位体系的结构更加稳定，并使Sm3+配位环境的对称性降低，从而其荧光强度远高于相应的小分子配合物。
Using 1, 10-phenanthroline as co-ligand and samarium (Sm3+) as the central ion, a series of novel samarium coordination polymers (PEK-Sm3+-Phen) were prepared. The FTIR and UV-Vis absorption spectra suggested that both the oxygen atoms of carboxyl groups of PEK and the nitrogen atoms of Phen were coordinated with Sm3+ ions.
通过红外光谱和紫外-可见吸收光谱分析表明钐离子同时与高分子配体和小分子配体发生了配位，且由X-射线衍射分析证实钐离子通过配位的方式能够均匀地分布于配位聚合物体系中。

The Pek in g Opera emerged in the capital as a dist in ctive theatrical form in the first part of the 19th century.
平剧是于19世纪初作为一种独特的戏剧形式出现在京城的。
Moreover, their emission intensities were much higher than that of the corresponding small molecular complex (Sm3+-Phen) due to the introduction of PEK with the rigid polymer chain, which could result in the stable coordination structure and the low coordination symmetry around Sm3+ ion in the PEK-Sm3+-Phen system.
同时讨论了不同高分子配体对配位聚合物荧光强度的影响，带有较多烷基取代基的PEK-1使PEK-1-Sm3+-Phen显示出最高的荧光强度。
