Several basic hypotheses have been supposed, and modelofstructure description of transboundary water pollution is brought forward combining the Chinese circumstances.
This article discusses the main theory of CSCL, theory of Learning, design of learning environment, interaction of learning, theory of knowledge and modelofstructure.
A new approach of full-mode flutter analysis with double parameters is proposed, which is realized in ANSYS, based on the full-order discretized physical modelofstructure.
