Besides, NAPH-PMABE has obviously third-order nonlinear optical properties which was introduced by the end-functional moieties of 1,8-naphthalimide.

这种聚合物的三阶非线性光学性能是由末端腙式结构的萘酰亚胺基团引入而产生的，其良好的成膜性使器件化成为可能。

In this contribution novel acid-base sulfonated poly(phthalazinone ether nitrile ketone)s membranes are introduced.The membranes are composed of SPPENKs as the acidic compounds,and polyetherimide as the basic compounds,furthermore,redissolving SPPENKs and PEI in N-methylpyrrolidone then cast directly onto clean glass substrates in dust free environment at 60℃ aiming at enhancing membrane toughness and other relative properties.

以合成的一系列不同磺化度的碘化聚芳醚腈酮为acidic聚合物，以聚芳醚酰亚胺为basic聚合物，并将其溶解在 N -甲基-2-吡咯烷酮中配成质量分数为10%的成膜液，60℃下刮制成膜，制得acid-base型磺化聚芳醚腈酮质子导电了聚合物膜。

The resulting polymers showed good thermal properties and excellent organosolubility even in common low boiling point solvents, such as acetone, chloroform and 1, 1, 2-trichloroethane, yielding a polymer solution with solid contents over 10wt%.

聚合物膜的紫外-可见光吸收阀值波长低于350nm，比线性类似物的（450nm）低许多，得益于超支化结构导致的酰亚胺环结构的疏松堆积，有利于以其为大分子骨架的光敏材料在365nm紫外工作波长的光刻。

The effect of assistant vulcanizing agent PDM on the properties of CM/NBR blends which is vulcanized by the peroxide is investigated.

研究了N，N'-间苯撑双马来酰亚胺对丁腈橡胶/氯化聚乙烯共混物性能的影响。

The determination of amino acids in blood clam antianaemia oral liquid using HPLC-AccQ-Tag method is reported. The oral liquid reacted with 6-aminoquinolyl-N-hydroxysuccini-mdyl carbamate. Then, the corresponding derivatives were analyzed with an HPLC. The chromatographic conditions were AccQ-TagTM C18 column for amino acids analysis (3.9mm×15cm); mobile phase of program elution sodium acetate solution(pH5.02), acetonitrile, Milli-Q water. The amino acids'AQC deriatives were detected at 248nm with a UV-detector. Eighteen kinds of amino acids were completely determined in 35 minutes.

以6-氨基喹啉-N-羟基琥珀酰亚胺基氨基甲酸酯为衍生剂，与毛蚶抗贫血口服液中的氨基酸柱前定量衍生，用WatersHPLC仪，AccQ-TagTM专用C18柱(3.9mm×15cm)，以140mmol·L-1的醋酸钠溶液(pH5.02)为溶剂A，乙腈为溶剂B，超纯水为溶剂C，进行梯度洗脱，检测波长为248nm，35min测试完毕。

The friction and wear behaviors of calcium sulphate whiskers modified bismaleimide resin under different friction load,coupling agent,and whisker content were investigated.

中文文摘］研究了载荷、偶联剂及硫酸钙晶须用量对双马来酰亚胺树脂摩擦磨损性能的影响及材料的磨损机制。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
