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。The still further analysis in connection with several actual examples reveals that the method can fairly accurately identify the numbers, sizes and action positions of the passing vehicles on the bridge in the state of sparse traffic volume, and can derive load under multiple vehicle action within the influential lines
結合實例的分析表明該方法能夠較精確識別稀疏交通狀態下車輛數量、大小、作用位置，並能推求影響線內多車作用下的荷載。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。
