The test results show that both the permeability of sandstone and that of granite with a single fracture decrease with increasing effective stress , following the law of exponential decay . the permeability sensitivity of granite to effective stress is more stronger than that of sandstone , but the permeability recovery capability of sandstone is more stronger than that of granite
试验结果表明，在围压升降过程中，砂岩和单裂隙花岗岩的渗透率均随有效应西南交通大学博士研究生学位论文第日页力的增加呈负指数规律减小，但单裂隙试件的渗透率对有效应力的敏感程度远大于砂岩，而砂岩渗透率的恢复程度则远大于单裂隙试件。
This dissertation investigates both existence of traveling wave solutions for delayed reaction diffusion systems and lattice differential equations , and global attractor of spatially discretized fitzhugh - nagumo equations with dirichlet or neumann boundary conditions . for delayed reaction diffusion systems , the existence of traveling wavefronts in diffusive and coorperative system with time delays is provided , firstly ; the monotone iteration scheme , together with upper - lower solution technique , is applied to establish the existence of traveling wavefronts of delayed reaction diffusion systems with some zero diffusive coefficients . secondly , schauder fixed point theorem is applied to some operators to prove the existence of traveling wave solutions in a properly subset equipped with exponential decay norm , which is obtained from a pair of upper and lower solutions for delayed reaction diffusion systems with non - quasimonotoiiicity
对于时滞反应扩散方程，我们先利用吴建宏和邹幸福[ j . dynam . diff . eqns2001 ( 3 ) ]中的主要定理来研究时滞竞争扩散lotka - volterra系统波前解的存在性，给出了这个定理在非线性项满足弱拟单调条件( qm * )时在系统情况中的应用；并利用单调迭代方法和上、下解技术，对于具有部分零扩散系数的时滞反应扩散方程建立波前解的存在性定理，对于具有部分零扩散系数的时滞反应扩散方程建立波前解的存在性定理。
In 1987 , a remarkable step was made by yablonovitch , who pointed out the possibility of the realization of photonic bandgaps , localized defect modes , and their applications to various optoelectronic devices , and by john who dicussed the strong localization of electromagnetic waves in disordered photonic crystals and also predicted many interesting quantum optical phenomena that can be realized in photonic crystals such as the bound state of photons and non - exponential decay of spontaneous emission
1987年yablonovitch和john开创性地提出光子晶体这一新概念， yablonovitch指出了有可能实现光子频率带隙和局域缺陷模以及许多光电技术方面的应用， john则讨论了在无序光子晶体中电磁波的强烈局域现象，并预言在光子晶体中存在许多有趣的量子光学现象，诸如光子局域态、自发辐射的非指数衰减。
