这样，优秀生、后进生的深层差异就昭然若揭了。

　　Excellent students are thus distinguished from poor students.

　　同样的课程、同样的教育方法，优秀生之所以比较恒定的“优秀”，

　　Taking the same course and by the same educational method, why do good students keep to be good?

　　只是由于其每节课后输出的心理愉悦感是正向的恒定，

　　It is because they always get a positive sense of pleasure after each lesson.

　　并在良性循环中积淀、固化为一种良性学习心理素质。

　　They get more and more pleasure in the beneficial cycle and the quality of good study psyche is thus formed.

　　这是学习“毅力”形成的深层动态机制。

　　This is the deep dynamic systemswheresstudy“will power”is formed.

　　而差等生之所以难以突破相对恒定的“差等”界限，

　　On the other hand, poor students find themselves difficult to get away from the“poor”boundary

　　也是由于几乎每节课后，输出的心理愉悦感是负向的恒定，即沉重感、压力感、枯燥感、厌烦感，

　　because after each lesson they always produce a sense of negative pleasure,that is,the sense of heaviness,pressure, dullness and resentment.

　　并在恶性循环中沉积、内化为一种恶性学习心理素质。这是学习“没毅力”形成深层动态机制。

　　The negative sense of pleasure increases in a vicious cycle and becomes a quality of bad study psyche.That is the deep dynamic system where“no will power”of study is formed.
