利用建立的饱和多孔介质中热弹性波的弥散方程,研究了平面p波在自由界面上的反射问题,获得反射系数的表达式。通过算例分析了饱和多孔弹性介质的热膨胀系数对p1波传播速度的影响,进而考虑界面透水与不透水两种工况,讨论了不同频率、入射角和表面排水条件对各反射波幅值的影响特性。结果表明:热物性参数对波的传播有一定的影响,频率、入射角和表面排水条件对两类压缩波、剪切波和热波的反射幅值的影响较大。 
采用热重-质谱(TG-MS)联用技术研究了N2气氛下废旧汽车塑料和橡胶高聚物混合物料热解气体的种类和产生机理.结果表明,废旧汽车高聚物热解过程在240~350 ℃和420~500 ℃有两个明显失重阶段,分别有20.9%和28.3%的挥发分析出.650~730 ℃范围失重峰是由无机填料热分解造成的,产生的挥发性气体产物为CO2.热解过程中所产生的H2、CH4、H2O和CO2等气体的大量释放阶段均在2...

I derive the distribution of energy and momentum transmitted from a fast parton to a medium of thermalized quarks, or the source term, in perturbative thermal field theory directly from the quark ene...
For a thermal field theory formulated in the grand canonical ensemble, the distribution of the total momentum is an observable characterizing the thermal state. We show that its cumulants are relate...
SrTiO3 is a promising n-type oxide semiconductor for thermoelectric energy conversion. Epitaxial thin lms of SrTiO3 doped with both La and oxygen vacancies have been synthesized by pulsed laser depos...
Recent results from the RHIC facility and first measurements from the ALICE experiment at the CERN-Large Hadron Collider (LHC) on open heavy-flavour are presented. We focus on RHIC measurements of sin...
The Hawking temperature for the Barriola-Vilenkin global monopole metric is shown to be TBV = ~(1− )2 8GMkB, where is the global monopole charge,M the mass of the black hole, kB is the Boltz...
The CASTOR calorimeter is a detector covering the very forward region of the CMS ex-periment at the LHC. It surrounds the beam pipe with 14 longitudinal modules each of which consisting of 16 azimutha...

Lattice measurements of spatial correlation functions of the operators FF and F ˜ F in thermal SU(3) gauge theory have revealed a clear difference between the two channels at“intermediate”distan...
We further develop a thermal LB model for multiphase flows. In the improved model, we propose to use the FFT scheme to calculate both the convection term and external force term. The usage of FFT sche...
We study numerically the in uence of density and strain rate on the di usion and mobility of a single tagged particle in a sheared colloidal suspension. We determine independently the time-dependent v...
A new method of measuring the pressure anisotropy in the early stage of heavy-ion col-lisions is discussed. It is shown that the transverse momentum spectra, elliptic flow and interferometry radii are...
At low temperature in the epsilon regime of QCD the low-end of the Dirac spectrum is described by random matrix theory. In contrast, there has been no similarly well established staistical descriptio...
