Results After 2 h WRS, the NO production, the NOS activity and L-arginine transport rate in rat platelets obviously increased and then gradually decreased. After 8 h of WRS, these parameters were decreased as compared with the control group. The gastric ulcer appeared and got more serious after 4 h WIR stress.

结果 WRS 2 h血小板L-Arg转运量、NOS活性和孵育液NO2含量较对照组显著增加，但随应激时间延长，其呈下降趋势，应激8 h时均显著低于对照组，胃溃疡逐渐加重。

The Cd2+ residues in Zizania galls in all treatments were lower than the national maximum residue standards of non2polluted vegetables.

表明茭白对Cd2+的忍耐性较强，虽然产品器官中的残留含量随处理时间延长而呈增加趋势，但生物富集程度较低。

Results indicated that introducing some ring-structure into UF molecule during the synthesis could efficiently improve the water resistance of UF resin. The Uron ring would form if reaction temperature was more than 75 degrees C, and the higher Uron content was obtained at pH 8 and 85 degrees C in the absence of catalyst when the reaction time was long enough.

结果表明：通过在脲醛树脂合成中引入Uron环等环状结构物质能够有效提高脲醛树脂胶黏剂的耐水性；当反应温度高于75℃时，反应产物都生成了一定量的Uron环物质；在pH值为8左右、温度控制在85℃、不使用催化剂、尽可能延长反应时间的条件下，尿素与甲醛成环化反应生成的Uron相对值最多。
