Review on hydrodynamic instabilities of a shocked gas layer

引用

Science China(Physics,Mechanics & Astronomy) 2023年第10期66卷 1-9页

Hydrodynamic instabilities induced by a shock wave can be observed in both natural phenomena and engineering applications,and are frequently employed to study gas dynamics, vortex dynamics, and turbulence. Controlling these instabilities is very desirable, but remains a challenge in applications such as inertial confinement fusion. The field of “shock-gas-layer interaction” has experienced rapid development, driven by advances in experimental and numerical techniques as well as theoretical understanding. This domain has uncovered a diverse array of wave patterns and hydrodynamic instabilities, such as reverberating waves, feedthrough, abnormal and freeze-out Richtmyer-Meshkov instability, among others. Studies have shown that it is possible to suppress these instabilities by appropriately configuring a gas layer. Here we review the recent progress in theories,experiments, and simulations of shock-gas-layer interactions, and the feedthrough mechanism, the reverberating waves and their induced additional instabilities, as well as the convergent geometry and reshock effects, are focused. The conditions for suppressing hydrodynamic instabilities are summarized. The review concludes by highlighting the challenges and prospects for future research in this area.

Counterexamples Concerning Quasiconformal Extensions of Strongly Starlike Functions

引用

Acta Mathematica Sinica,English Series 2007年第10期23卷 1859-1868页

作者： yu liang SHEN Department of Mathematics Suzhou University Suzhou 215006 P. R. China

M. Fait, J. Krzyz and J. Zygmunt proved that a strongly starlike function of order α on the unit disk can be extended to a k-quasiconformal mapping with k ≤ sin（απ/2） on the whole complex plane C which fixes the point at infinity. An open question is whether such a function can be extended to a k-quasiconformal mapping with k 〈α to the whole plane C. In this paper we will give a negative approach to the question.

After reviewing Grunsky operator and Faber operator acting on Dirichlet space,we discuss the boundedness of Faber operator on BMOA,a new subject which turns out to be closely related to the BMO theory of the universal Teichmüller *** particular,we show that the Faber operator acts as a bounded operator on BMOA if the symbol conformal map stays nearly to the base point in the BMO-Teichmüller ***,we obtain several results on quasiconformal mappings,BMOTeichm¨uller space and chord-arc curves as *** by-products,this provides a complex analysis approach to the boundedness of the Cauchy integral acting on BMO functions on a chord-arc curve near to the unit circle in the BMO-Teichmüller space.

Growth and alkaline phosphatase activity of Chattonella marina and Heterosigma akashiwo in response to phosphorus limitation

引用

Journal of Environmental Sciences 2015年第2期27卷 1-7页

作者： Zhao-Hui Wang yu liang College of Life Science and Technology Key Laboratory of Eutrophication and Red Tide Prevention of Guangdong Higher Education InstitutesJinan University

The growth and alkaline phosphatase activity（APA） of two raphidophyceae species Chattonella marina and Heterosigma akashiwo were investigated in response to P-limitation and subsequent addition of dissolved inorganic phosphorus（DIP, Na H2PO4） and two dissolved organic phosphorus（DOP） compounds： guanosine 5-monophosphate（GMP） and triethyl phosphate（TEP）. APA levels increased greatly after P-starvation as the decrease of the cellular phosphorus quotes（Qp）. C. marina responded to P-limitation quickly and strongly, with 10-fold increase in APA within 24 hr after P-starvation. The larger difference between maximal and minimal QP values in C. marina indicated its high capacity in P storage. APA of H. akashiwo was maximally enlarged about 2.5 times at 48 hr of P-starvation. After the addition of nutrients, cell numbers of C. marina increased in all treatments including the P-free culture, demonstrating the higher endurance of C. marina to P-limitation. However, those of H. akashiwo increased only in DIP and GMP cultures. APA increased only after the addition of the monophosphate ester GMP. The results suggest that quick responses of C. marina to P-limitation, high capacity in P storage as well as endurance for P-depletion provide this species an ecological advantage in phytoplankton community competition under DIP-limited conditions.

New better estimates, which are given in terms of elementary functions, for the function r →（2/π）（1 -r2）κ（r）κ′（r）＋ logr appearing in Hubner＇s sharp upper bound for the Hersch-Pfluger distortion function are obtained. With these estimates, some known bounds for the Hersch-Pfluger distortion function in quasiconformal theory are improved, thus. improving the explicit quasiconformal Schwarz lemma and some known estimates for the solutions to the Ramanujan modular equations.

An Effective Description of Electron Correlation in the Green Function Approach

Chinese Physics Letters 2013年第4期30卷 161-165页

作者： LIU yu-liang Department of Physics Renmin University of ChinaBeijing 100872

Beyond the usual many body perturbation theory,with the eigenfunctional theory,we directly calculate the correlation function produced by the Coulomb interaction of electrons in the equation of one-electron Green function,and give the general expression of the non-local effective interaction potential in a Hartree-type potential,which is absent in all previous many body perturbation *** effective interaction potential originates from the quantum many body effect of the system,and it cannot be obtained directly by the usual perturbation expression ***,using theoretical models,we demonstrate that this effective interaction potential can be used to characterize the electron correlation strength of the system.
