狭义的选择性,包括化学方面的选择性和射频方面的选择性。 广义的选择性,是表达“有选择地”的性质。“选择性XX”意味着在某方面的“有选择地”,即有选择性。(是选择恐惧症而非“选择性恐惧症”,是“选择障碍”“而非选择性障碍,滥用“选择性”一词是语法的错用。) 因“选择性”一词在各科学领域都有应用,其可以作为一个深刻的哲学范畴(但长期被忽略)。选择性可分为主动选择性与被动选择性。
...对功能亢进者用抑制药,使机体功能在药物效应的影响下达到新的动态平衡。二、药理作用的方式二、药理作用的方式药理效应选择性(selectivity)是指药物引起机体产生效应的范围的专一或广泛程度。药理效应的选择性受较多因素的影响,如在药物的剂量改变时可明显影响其效应范围...
