One of the key ideas in modern evolutionary theory is that of preadaptation. 现代演化理论的一个关键概念是预先适应（preadaptation）。
On a plentiful diet there is no difference, but on a restricted diet this preadaptation could be decisive. 食物丰富时抗性没有区别；但当食物有限时，这一预适应可以是决定性的。
The research about ATP-sensitive K+ channels is mainly focused on the cytoprotection of tissue ischemia and preadaptation or tissue ischemia-reperfusion. 对ATP敏感性钾通道的研究主要集中于各种组织的缺血及预适应或缺血再灌注的细胞保护方面。
Conclusions Ischemia preadaptation can protect myocardium injury in ischemia reperfusion, the protection is mainly reflected by reduction of myocardium enzyme activity,myocardium infarct area and subcellular structure injury. 结论缺血预适应可以降低心肌酶活性,缩小梗死面积,改善亚细胞结构损害,对心肌缺血再灌注损伤有保护作用。
