sulfamethoxine

Two new Schiff bases have been synthesized from sulfamethoxine with p-hydroxybenzaldehyde(H2L, 1) and from sulfacetamide with benzoylacetone(HL', 2).

采用周效磺胺与对羟基苯甲醛、磺胺醋酰与苯甲酰丙酮合成两种新西佛碱(1,H2L为周 效磺胺西佛碱;2,HL'为磺胺醋酰西佛碱),并用上述配体制备两种类型的稀土配合物,通过元素 分析、红外光谱、核磁共振、热分析、摩尔电导和溶解性试验对配合物进行了表征。

The crown efficiency only considers the loss in the channel of stator and rotor and the residual speed loss, clearly showing the relationship between the pneumatic angle and turbine efficiency.

轮周效率只考虑定子、转子流道中的损失、余速损失,较明显地反映了流道中气流角度与涡轮效率的关系。

Then this paper integrates the daily contrariant profit and day-week effect.

同时,进一步将日度反向利润与日周效应这两种异常行为相结合,研究周内各交易日股价变动对日度反向利润的影响差异,结果表明:当持有期为周一时,反向策略收益表现为动量效应,对日度反向利润影响为负;周二、三、五时表现为反向效应,对日度反向利润影响为正。
