求解了當時一般情況下標準宇宙模型方程，通過一般地求解不同密度物質情況下的暴漲宇宙演化方程，得到了的一般物質密度的表達式，解出了表徵宇宙標度因子不同演化的一般新解，並通過對不同情況下標準宇宙方程的求解，證明參數的正負取值直接影響宇宙尺度因子的表達形式。 -
First, we concisely recall the formation and development of bose - einstein condensa - tion ' s theory and it ' s experimentation. secondly, we briefly intro - duce some properties of weakly interactive bose gases, and derive the nonlinear gross - pitaevskii equation that is the condensate macroscopic wave function ' s equation. thirdly, we give a exam - pie, an approximation analytical solution of the gross - pitaevskii equation in a spherical symmetric harmonic trap is derived by a perturbation theory approach, this solution is consistent with that numerically obtained
全文共分為四章：第一章首先簡要的介紹和回顧了玻色-愛因斯坦凝聚理論的產生和發展，以及其實驗研究的過程，然後著重介紹了弱相互作用的玻色氣體的一些性質，並推導出了凝聚體宏觀波函數滿足非線性的gp方程，還以球對稱的諧振子勢為例，用標準的微擾方法求出了定態的gp方程近似解，發現其與已知的數值結果符合得很好。 -
Then combined with the two main mechanisms it is putting forward the idea of compound - mechanism antimicrobial. as a result, there come the two types of nano - inorganic antimicrobials : ( 1 ) ion - sterilizing antimicrobial which utilized the sterilization function of re and used the powder ( active sio2 ) as carrier. ( 2 ) compound - mechanism antimicrobial which has both the sterilization function of re and the light - catalyzing sterilization function of nano - tio2 whose wavelength of light - absorption has einstein shift because of the mix - into of re
首先對市場上主要的抗菌劑產品進行歸類，對其殺菌機理進行對比分析，結合離子殺菌與光催化殺菌，提出了復合機理抗菌劑的思想，研製出：以稀土為殺菌主體，活性sio _ 2為載體的離子型抗菌劑；以稀土為離子殺菌部分，納米tio _ 2為載體，且在稀土離子的摻入下，納米tio _ 2的光吸收波長發生紅移，進入可見光區而提高光催化能力的復合機理抗菌劑。 -
Chapter 3. the bose - einstein distribution and the thermodynamics equilibrium condition which are obeyed by the photons during spontaneous raman scattering in the fiber are developed. the occupation probability ( s, as ) of stokes photon and anti - stokes photons and temperature ( t ) can be regarded as the function of the position along the fiber axis
第三章，研究了自發raman散射中光子所遵從的bose - einstein分佈及其平衡條件，給出了光纖中兩種光子布居概率_ s 、 _ （ as ）和溫度t看作位置z的函數的關系。
