当湿度液位低于设置点下的7%，这款恒湿器将会被激活，开始补充湿度损失。
When the humidity level drops to about 7% below the set point, the humidistat will activate to replenish the loss of humidity.
当TNFR被激活以后，它使细胞释放出信号分子-化学增活素，化学增活素引导免疫细胞到达破坏或感染的位点。
When TNFR is activated, it causes cells to send out signal molecules called chemokines that direct immune cells to the site of damage or infection.
协同性转录激活的本质是多个结合在调控位点上的激活蛋白之间直接或间接的相互作用。
All these mechanisms involve direct or indirect interactions among multiple activators that bind to upstream regulatory sites.
其激活和转位机制可能与其不同的活化因子或底物和不同位点的氨基酸残基磷酸化有关。
The mechanisms of its activation and translocation may be associated with the difference of the activation factors or its targets, and the amino acid residues of different phosphorylation site.
