And there is some type of criterion or standard against which comparisons are made in order to assess whether the process should continue as is or if some type of change is necessary . and self - regulatory activities are mediators between personal and contextual characteristics and actual achievement or performance 学习的自我调节可以从调节过程的阶段和被调节的领域两大方面进行整合，成为一个统一的模型，来统摄所有的有关因素，以解释人类学习的自我调节原理。
Renin - angiotensin system ( ras ) plays an important role in the regulation of peripheric blood pressure , where angiotensin converting enzyme ( ace ) is considered to be the core of the system . ace plays a key role in increasing the blood pressure by catalyzing the formation of the potent vasopressor angiotensin ii ( ang ii ) from angiotensin i ( ang i ) 在该系统中， ace酶是血压调节过程中一个关键的酶，它可以将无活性的血管紧张素( ang )水解生成具有血管收缩作用的血管紧张素( ang ) ，从而导致血管收缩，机体的血压升高。
This paper discusses the attributes , understanding dimensions and the influencing factors of self - regulation , by analyzing great quantities of relative researches , and outlines a new model of self - regulation in learning . it is our view that the function of all the concerning researches lie in revealing the mechanism of regulation in learning . we view learners as active , constructive participants in the learning process 本研究主要使用文献法，通过对大量相关资料的分析，对已有研究成果和以班图拉和齐莫曼为代表的各种理论观点进行了全面梳理和综合提炼，论述了自我调节学习的基本性质、研究维度和影响因素，概括了学习的自我调节过程，重点提出了一个整合性的学习的自我调节模型，以期从整体上对学习自我调节的基本机制有一个较为准确清晰的把握。
