**Abstract
****The
power band graph (PBG) method is a convenient system dynamic modeling method,
which is used successfully in fluid system dynamic character simulation. As
there are many similarities to a great extent between biological fluid system
and engineering fluid system, according to fluid dynamic theory, this paper
use the PBG approach in the computer simulation of human blood circulation
systemand
complete a modeling and simulation study on a simplified human blood circulation
system model. The results of the simulation are in good agreement with the
basic physiological law. The study provides a simple and unitary simulation
modeling method for physiologic medical simulation.**

**Abstract:**The
homogeneous balance method is extended to search for Backlund transformation
and similarity reduction of nonlinear partial differential equations. It
is shown that there exist close connections among the homogeneous balance
method, WTC method and CK direct reduction method.
The variant Boussinesq equations are discussed as an illustrative example.
Their Backlund transformation, linearization transformation and three types
of similarity reductions are obtained. In the meantime, some new travelling
wave solutions also are found. q2000 Published by Elsevier Science B.V. All

Communicated by C.R. Doering

**Abstract:**An
extended tanh-function method is proposed for constructing multiple travelling
wave solutions of nonlinear partial differential equations (PDEs) in a unified
way. The key idea of this method is to take full advantages of a Riccati equation
involving a parameter and use its solutions to replace the tanh function in
the tanh-function method. It is quite interesting that the sign of the parameter
can be used to exactly judge the numbers and types of these travelling wave
solutions. In addition, by introducing appropriate transformations, it is
shown that the extended tanh-function method still is applicable to nonlinear
PDEs whose balancing numbers may be any nonzero real numbers. Some illustrative
equations are investigated by this means and new travelling wave solutions
are found. *

**Abstract. **An
explicit N -fold Darboux transformation with multiparameters for a kind of
coupled derivative nonlinear Schr odinger equation is constructed with the
help of a gauge transformation of a spectral problem. As a reduction, a Darboux
transformation of the GerdjikovCIvanov equation is obtained. Furthermore,
the explicit soliton-like solutions of the GerdjikovCIvanov equation are given
by applying its Darboux transformation.

Received 1 September 2000, in final form 6 December 2000

**Abstract:**A
spectral problem and the associated hierarchy of Schr odinger type equations
are proposed. It is shown that the hierarchy is integrable in Liouvilles
sense and possesses multi-Hamiltonian structure. It is found that several
kinds of important equation such as the KaupCNewell (KN) equation, the ChenCLeeCLiu
(CLL) equation, the GerdjikovCIvanov (GI) equation, the modified KortewegCde
Vries equation and the SharmaCTassoCOlever equation are members in the hierarchy
as its special reductions. Moreover, KN, CLL and GI equations are described
by using a unified generalized derivative Schr odinger equation involving
a parameter, and their Hamiltonian structure and Lax pairs are also given
by unified and explicit formulae.
