文摘The weak nonlinear modulation of the surface wave of a three-dimensional imcompressible fluid without rotation, which is contained in a rectangular trough is studied by using the method of multiple scales perturbation theory. The effects of viscid and external drive on the motion, which modifies the Larraza- Putterman equation, are considered. The results are consistent with that of Miles.
文摘On the basis of clarifying the teachers'Ethics internalization theory,this paper analyzes the typical dilemma in teachers'Ethics internalization.To resolve these problems,this paper construct an overall framework,including security mechanism,normative mechanism,education mechanism,evaluation mechanism and supervision mechanism,which the external conditions are used to constantly strengthen the moral needs of the subject,then enhance the consciousness of moral internalization,improve the effectiveness of teachers'moral construction.
