Glass fibre reinforced magnesium cement corrugated sheet and ridge tile
玻纖鎂質膠凝材料波瓦及其脊瓦On the other hand, various techniques using the dhbs have been applied in optical traps for microscopic particles, guiding, cooling and trapping for neutral atoms as well as in manipulations and control of coherent matter waves ( i. e., bose - einstein condensations ( bec ) ) and so on
同時，其他的一些研究小組開展了暗中空光束在光阱與微粒的操縱、中性原子的激光導引、冷卻與囚禁以及相干物質波（如玻色-愛因斯坦凝聚， bec ）的操縱與控制等領域的應用研究。Some wavelengths are absorbed faster than others, depending among other things on the properties of the material it passes through
物質的性質不同影響不同波長的光的吸收速度，這樣就產生了染色玻璃。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。The research progress and the facing difficulties of active / passive planar optical waveguides were systematically summarized and reviewed in this paper. zro2 - si02 binary oxide gel glasses and films applied for active optical waveguides were prepared by the sol - gel method with zirconium oxychloride and tetraethoxysilane as precursors. the paper has investigated the influence of the compositions of system and heat treatment temperature on the system refractive index in zroj - sioj binary oxide gel glasses
