  1. The basic thought is to divide the cities which are close to each other into a group ( physical area ) by applying sorting neural network, find out the optimal path by the improved hnn, and then calculate the local optimal path by using the same method, and finally get the whole optimal path, which are described as following : a assembly s of cities is grouped into some subsets according to their physical location and we can get, and then get the optimal, path of tsp of s = { s, i = 1, 2, n } through the given method, as well as the st

    基本思想是利用聚類神經網路先把地理位置上相互靠近的城市劃分為一個集體單位（一個物理區域） ，用改進的hopfield神經網路演算法求解各個區域間的最優（或近似最優）路徑，然後再在每一個區域內部用同樣的方法來求解其局部的最優（或近似最優）路徑，這樣可以最終得到全局的最優（或近似最優）解。描述如下：設有城市集合s ，按城市的地理位置把s劃分為若干子摘要2集，得s ijs ， ，其中廠s ； d ， i一口求得集合i叫s s ； i習， 2 ， … n的tsp最優路徑，再依次求得子集s ；內部的tsp最優路徑，即得最終優化路徑m一） s一） …一寧s ； di
  2. Finally, we present the approximate distribution of trapping potential of the guided cold atoms in the atomic funnel based on the vccc or the uccc. by using a similar method in the analysis of optical coherence, we study the coherent evolution of the ground - state wave function of ultra - cold atoms in atomic funnel, and obtain some normalized correlation functions of the first, second, third and high order

    最後，給出了原子在基於v -型和u -型載流導體構建的原子漏斗中所感受到的囚禁勢的摘要採用漂流導體的原子易引及其原於光學器件近似分分，並採用類似於光場相干性的分析方法，計算了超冷原子物質波的基進波函數及其在原子漏斗中傳播時相干性的演化，得到了物質波的一階、二階、三階和高階相於度。
  3. Up to now, the method, we used in studying the properties of collective multipole excitations of nuclei, treat the continuum by a discretization procedure with expanding wave functions in a harmonic oscillator basis. this approximation can be justified for very narrow resonances and gives a global description of the contributions from the continuum. a complete treatment of the continuum can be carried out by the continuum rrpa with a green " s function method

    為了解決這些問題，需要改進相對論無規位相近似方法對z連續態的處理，採用連續相對論無規位相近似計算，通過格林函數方法可以嚴格處理連續態在核的集體激發中的貢獻，並用來描述核的集體巨共振性質，包括核的巨共振能量、巨共振峰的強度以及巨共振寬度等重要的物理量。
  4. Such limit is not due to the method itself, but is due to the limits of the speed and memory of computers. at present, we mainly use the high - frequency approximate method to analyze the electrical - large size target whose shape is relatively regular

    矩量法不適于分析電大尺寸的物體，這種限制不是由於方法本身，而是碩士學位論文凡1入ster 』 5th卜515由於計算機速度與存儲能力的限制。目前主要採用高頻近似方法來研究電尺寸較大而形狀相對規則的目標。
  5. Two - order enhanced un - split finite volume euler method for multi - fluid flow, which combines the roe approximate riemann solver, is developed to simulate the multi - fluid interactions, such as the fluid described by polynomial eos, stiffen gas eos, jones - wilkins - lee ( jwl ) gaseous explosive eos, cochran - chan ( cc ) solid explosive eos and hom shock wave eos, etc. numerical results of the id, 2d and 3d multi - fluid interaction examples show that the high - resolution method and interface capturing equations can resolve the multi - fluid flow correctly and successfully. a simple fluid - mixture type ppm algorithm for multi - fluid flow, which is based on vof interface capturing method and resolved by langange / remap two steps, is developed to simulate the high density or high pressure ratio flow at both sides of the interface

    本文提出了實用於多介質流體的增強型二階精度有限體積歐拉數值計算方法，採用roe方法近似求解riemann問題，可以適用於多項式狀態方程、 「 stiffengas 」狀態方程、 jones - wilkins - lee爆轟產物狀態方程、 cochran - chan固體炸藥狀態方程以及hom狀態方程等，並對多介質流體相互作用的一維、二維、三維問題進行數值計算，數值驗證了本文給出的高精度差分格式和界面捕捉方法的正確性，兩種方法耦合形成的多介質流體數值計算方法是成功的。
