Abstract:
Some new advances in the research of mathematical models of structures and materials, materials and instruments, theories and methods, and integrated passive and active vibration controls are reviewed, with the focus on the vibration control of aerospace flexible structures. The integrated passive and active vibration is a research focal point of aerospace flexible structure vibration control. These two kinds of vibration control techniques have their respective advantayes and can be used to improve the p...

Abstract:
This paper reviews the applications of singular integral equation (SIE) to the scattering problems of elastic waves by cracks, especially by interface cracks, which were made during past two decades. Several problems such as the reduction of the scattering problems to the SIE, the solution of the SIE and the relationship between the SIE method and other integral equation methods are discussed.Finally, possible applications of the SIE to the scattering problems of cracks are suggested.

Abstract:
Dust particles generated in processing plasmas are a key factor affecting quality in semi-conductor production, so that many scientists pay a great deal of attention to it in recent years. Dusty plasma research becomes an important front branch in plasma physics.This paper gives a review of the research progress on particle behaviors in processing plasmas, including particle nucleation, growth, trapping,charging, forces on particles, transport and strong couple characteristics. The major measurement methods...

Abstract:
The research of ventricular afterload, pump function of heart, ventricle arterial coupling and their clinic applications have undergone rapid development in the last twenty years In the staticcase, the study of the problem has come to a rather mature stage In the dynamic case, many animal experiments and some theoretical models were proposed In this paper, we first review the progress in above three aspects during the last twenty years, then we present our recent research results, and lastly we poin...

Abstract:
The effects of imperfections on stability of structures are directly related to failure analyses of structures. In the paper, the theory, variational principles, finite element method for perforated cylindrical shells and its applications for the stability analysis are briefly reviewed with holes in structures regarded as one kind of initial geometric imperfections. The effects of holes on critical loads of cylindrical shells under axial compression are discussed.

Abstract:
Fracture size effects for concrete structures have been a very important field of civil engineering for more than ten years. In the paper the size dependency of some conventional fracture parameters are discussed,some tests on fracture process zone are described, the studies on size effect both in China and abroad are analyzed and reviewed. Some comments are made on the development trends of fracture size effect for concrete structures.

Abstract:
Study on whole field measuring technique for fluid flow velocity is of high academic value and has many practical applications in fluid mechanics and aerodynamics. An overview on these techniques in the last decade is presented in this article. Several techniques are analyzed and evaluated, such as the technique of laser induced fluorescence for high speed flows, two dimensional particle tracking velocimetry and particle image velocimetry and the recent advances of three dimensional velocimetry.
