  1. The number density distribution of globular cluster in space will change with time due to the dynamic evolution, especially for those in the central region of the galaxy ; 5. for the power law initial cluster mass function, the peak value of the mass function after the dynamic evolution is sensitive to the lower limit of the initial mass function we adopt. the suggested value in this paper is - 104m, which is consistent with that reduced from the dynamical analyses for the giant molecular clouds

    對于冪率的初始質量譜，球狀星團系統動力學演化后質量分佈的轉折點質量主要是由初始質量函數的質量下限決定的，最為適合的值為10 ~ 4m _ ；冪率的初始質量譜的譜指數對球狀星團系統動力學演化后質量分佈的轉折點質量也有影響，其最佳值為1 . 5 2 . 0 ；經過大約5gyr的動力學演化，冪率的初始質量譜就會演化成為高斯的對數質量分佈並具有在隨后的動力學演化中保持對數高斯形式質量分佈的特性。
  2. The mostly content in this paper include the law of the influence upon the effective stress coefficient worked by the holes configuration which comprise the holes rate and the hole distributing, and the law of the influence upon the effective stress coefficient worked by the cracks configuration in rock which comprise the amount of cracks and the cracks distributing. by numerical value experiment, the variety laws of the effective stress coefficient worked by the cracks distributing, by the fractal dimension and the initial value have been work out. by referring to the formerly physical experiment datum and conclusion, the thesis has studied the influence upon the effective stress coefficient worked by the outside pressure and the liquid press inside rock and sum - up the variety law of the effective stress coefficient with the outside pressure and the liquid press

    本文的主要內容包括：巖體孔隙裂隙結構對有效應力系數的影響規律，即：一是孔隙率大小及分佈形態對有效應力系數的影響規律，二是裂隙的條數和分佈形態對有效應力系數的影響規律，並得出了裂隙的分形參數，即：分形維數和裂隙初值的變化對有效應力系數的影響的相關規律，同時也搞清了裂隙分佈形態對有效應力系數的影響規律；參照已有的物理試驗結果，分別研究了巖石所受的圍壓和孔隙流體壓力的變化對有效應力系數造成的影響，從細觀的角度揭示了有效應力系數隨二者的變化規律。
  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. Then on the base of the computer model, the standard reentry trajectory guidance law is studied, and an approach to obtain the guidance coefficients by modifying the initial value through feedback bias repeatedly is put forward. simulations have proved the feasibility of the method

    在這個基礎上，本文對飛船再入標準軌道制導方法進行了研究，提出了一種利用制導參數偏差迭代求解反饋增益系數的方法，並通過大量模擬驗證了此方法的可行性。
  5. In this paper, the author propose a new gm ( 1, 1 ) model for oscillation series using the transformation of triangle function, and change them to be the monotone series, then constructe gm ( 1, 1 ) model for simulating prediction of original given data. 3. research on gm ( 2, 1 ) model, the author find that there is no law to choose the initial value of gm ( 2, 1 ) model

    因此，利用本論文提出的新的函數變換數據生成辦法，提出一種函數變換型gm （ 1 ， 1 ）模型，即將初始的周期振蕩數列首先變換成單調增加數列，再利用gm （ 1 ， 1 ）模型進行預報。
