  1. The hyperbolic conservation laws with relaxation appear in many physical systems such as nonequilibrium gas dynamics, flood flow with friction, magnetohydrodynamics, etc. firstly, the thesis proves that there exists a unique global smooth solution for the cauthy problem to the hyperbolic conservation laws system with relaxation ; secondly, in the large time station, the thesis proves that the global smooth solutions of the hyperbolic conservation laws system with relaxation converge to rarefaction waves solution at a determined l ( p > 2 ) decay rate

    帶鬆弛項的雙曲型守恆律組出現在諸多的物理系統中。例如，非平衡態的氣體動力學、帶摩擦的水流、磁動力學等。本文首先證明，帶鬆弛項的雙曲型守恆律組的柯西問題的整體光滑解的存在唯一性；其二，證明了帶鬆弛項的雙曲型守恆律組的解與相應的平衡態守恆律的稀疏波解在大時間狀態下的l ~ p衰減率。
  2. A stream of particles or electromagnetic waves emitted by the atoms and molecules of a radioactive substance as a result of nuclear decay

    核衰變產生的微粒或電磁波放射物的原子或分子由於核衰變放出的一束微粒或電磁波
  3. In chapter 1, the thesis studys the following cauthy problem to hyperbolic system with nonlinear relaxation term we prove that for the initial value with bounded c1 norm, there exists a unique global smooth solution for the cauthy problem ( 1 ), ( 2 ) ; in chapter 2, the thesis considers the following hyperbolic system with relaxation term and the sclar conservaton law equation when e is fixed, for a certain class of initial data, in the large time station, the thesis gets a determined lp ( p > 2 ) decay rate between the golbal smooth solutions of system ( 3 ) and the rarefaction waves solution of equation ( 4 )

    在第一章中，研究如下帶非線性鬆弛項的雙曲組的柯西問題證明了，對c ~ 1模有界的初值，柯西問題（ 1 ） ， （ 2 ）存在唯一的整體光滑解。在第二章中，考慮如下帶鬆弛項的雙曲組和單守恆律方程u _ t + f （ u ） _ x 0 ， （ x ， t ） r r ~ + 。 （ 4 ）當固定時，對一類初值，得到方程組（ 3 ）柯西問題的整體光滑解與方程（ 4 ）的稀疏波解間在大時間狀態下的l ~ p （ p 2 ）衰減率。
  4. 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開創性地提出光子晶體這一新概念， yablonovitch指出了有可能實現光子頻率帶隙和局域缺陷模以及許多光電技術方面的應用， john則討論了在無序光子晶體中電磁波的強烈局域現象，並預言在光子晶體中存在許多有趣的量子光學現象，諸如光子局域態、自發輻射的非指數衰減。
