醛糖或酮糖被还原后变产生糖醇,确实的叫法为“多羟糖醇”(alditols),HOCH 2 -(CHOH)n-CH 2 OH。
At last, the target product 4-Hydroxypyridine was gaven by reduction of 4-Hydroxypyridine N-oxide using zinc and Ammonium Formate as catalysts.
然后脱硝基得到4-羟基吡啶-N-氧化合物,最后用锌和甲酸铵还原4-羟基吡啶-N-氧化合物得到产物4-羟基吡啶。
Under different B4C content, layer cover to melt dark to appear change that make a reduction of after increasing with B4C increase of content layer, melt widely and present "n" type change.
在不同的B4C含量下,熔覆层的熔深随b4c含量的增多出现先增后减的变化,熔宽出现“N”型变化。
Plant absorption was not the main mechanism in reduction of both N and P, due to less plant biomass on wetland buffer zone.
缓冲带内的湿地植物量较小,决定了植物吸收并非氮磷去除的主要机制。
The reduction speed is increasing along with the concentration of N and P in water, whereas the removal rate of N and P is descending.
氮磷浓度的降低速率随水体中氮磷浓度的升高而升高,而对氮磷的去除率随水体中氮磷浓度的升高而降低。
