在这篇论文里，我们介绍利用飞秒萤光上转移方法研究偶氮苯在激发态的的光致顺反异构化动力行为。

To improve the cyano reactivity, cyano-terminated PPENs were prepared by the end-capping reaction of PPEN-OL with CBN; benzonitrile terminated polys were also prepared by the polycondensation of excess 4,4'-oxydianiline with 1,2-dihydro-2-(4-carboxyphenyl)-4-[4-(4-carboxyphenoxyl)phenyl]-phthalazinone, followed by end-capping with CBA. The polymers synthesized exhibited good solubility in NMP, DMAc and DMF, and were crosslinked to afford phenyl-s-triazine-containing polymers under the similar conditions.

为提高氰基活性，以对氯苯腈为原料，对PPEN-OL进行封端，设计合成了含氰端基的聚芳醚腈；以含二氮杂萘酮联苯结构二酸单体与4，4'-二氨基二苯醚为原料，经Yamazaki膦酰化缩聚，并用对氰基苯甲酸进行封端，合成了含氰端基的聚芳醚酰胺。

This indicated that, with the different pH values in solution, the adsorption site of biliverdin could be changed.

在酸性溶液中，胆绿素分子环C上的氮原子和内酰胺环A上的氧原子发生了质子化。

An animal model of DM was established byinjecting a little dosage ofSTZ in high fat-fed rats. When the model was establishedsuccessfully, corresponding medicine were supplied for 12 weeks and then the ratsweight、biochemical criterions, blood glucose, GSP and the content of NO, ET, hs-CRP,AR, IL-6, TNF-a in rats serum were mensurated.

The irrigation rate of infiltration irrigation and drip irrigation was half the rate of furrow irrigation in each event.

从累积矿化氮量－时间曲线变化的趋势看，可将保护地土壤0~50cm剖面分为三个层次，其中渗灌与滴灌处理相似，为0~20cm、20~40cm和40~50cm土层，而沟灌处理则为0~30cm、30~40cm和40~50cm土层。

The bubble contours were extracted from the experimental images by means of Matlab toolboxes.

对氮气泡在电场作用下的形成过程进行了可视化研究。
