retarded reaction

Synthesis of b-MAP Using Phosphorus-Containing Plasticizer as Reaction Medium and Its Flame Retarded PP

以含磷增塑剂为反应介质合成单分子型膨胀阻燃剂b-MAP及阻燃聚丙烯的研究

The hydration of blended cement was retarded in low-temperature curing stage, but the reaction degree could still increase in later standard curing stage.

早期低温养护情况下混合水泥的水化受到抑制，其反应程度相当低，但后期标养条件下有一定增长。

Under high phosphorus level ( 375 kg/ ha), Chlb content, Hill reaction and non-cycle photophosphorylation activities of flag leaves were retarded, and these parameters showed a similar regularity change indicating they were more sensitive to phosphorus than the other parameters determined.

高施磷量（P2O5375kg/hm2）时，旗叶的叶绿素b含量（Chlb）减少、希尔反应和非环式光合磷酸化活性受到抑制，对磷肥的响应规律基本一致。
