【摘要】

：

页岩气储层孔隙结构复杂,纳米孔隙所占比例大,而纳米孔内部气体流动机理不同于宏观流体流动,因此认识页岩气在纳米孔隙中的流动机理对页岩气的高效开采具有重要的科学意义.页岩气开采过程中,纳米孔的吸附解吸、应力敏感效应及滑脱效应使渗透率发生显著变化.为此,基于毛细管模型耦合考虑吸附变形修正应力应变的渗透率模型,在此基础上,考虑滑脱效应影响,建立页岩表观渗透率模型来描述气体流动.通过试验数据验证其合理性,并

Cohomology structure for a Poisson algebra:Ⅱ

For a Poisson algebra,we prove that the Poisson cohomology theory introduced by Flato et al.(1995)is given by a certain derived functor.We show that the (generalized) deformation quantization is equivalent to the formal deformation for Poisson algebras un

Gradient estimates for nonlinear diffusion semigroups by coupling methods

In this paper,we obtain gradient estimates for certain nonlinear partial differential equations by coupling methods.First,we derive uniform gradient estimates for certain semi-linear PDEs based on the coupling method introduced by Wang in 2011 and the the

Twisted toroidal Lie algebras and Moody-Rao-Yokonuma presentation

Let g be a (twisted or untwisted) affine Kac-Moody algebra,and μ be a diagram automorphism of g.In this paper,we give ah explicit realization for the universal central extension (g)[μ]of the twisted loop algebra of g with respect to μ,which provides a Moo

The second discriminant of a univariate polynomial

We define the second discriminant D2 of a univariate polynomial f of degree greater than 2 as the product of the linear forms 2rk-ri-rj for all triples of roots ri,rk,rj of f with i ＜ j and j ≠ k,k ≠ i.D2 vanishes if and only if f has at least one root wh

Stability results of properties related to the Bishop-Phelps-Bollobás property for operators

We prove that the class of Banach spaces Y such that the pair (l1,Y) has the Bishop-Phelps-Bollobás property for operators is stable under finite products when the norm of the product is given by an absolute norm.We also provide examples showing that the

Global well-posedness and large-time behavior of 1D compressible Navier-Stokes equations with densit

We consider the Cauchy problem for one-dimensional (1D) barotropic compressible Navier-Stokes equations with density-depending viscosity and large external forces.Under a general assumption on the density-depending viscosity,we prove that the Cauchy probl
