從1928年起至1956年，印度隊以絕對優勢連續獲得6屆奧運會曲棍球冠軍，在該項目上稱霸世界近30年。He says there is an over - emphasis on climate change as the only form of environmental _ _ 2 _ _ that poses challenges to the planet
他稱如今有一種把氣候變化作為環境退化唯一方式而過分強調的趨勢。環境退化對我們的星球提出了挑戰。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 prediction of disastrous space weather is a hot topi c among solar - terrestrial physics and high technological fields. we propose that the future forecasting of the physical conditions that the violent solar disturb ance causes at the earth by propagating in solar wind depends heavily on the num erical method. this paper analyses the existing problems we are facing in the num erical prediction of disastrous disturbance events in solar - terrestrial space, an d then gives some suggestions for future study. for such a purpose, a six step sol ution method is developed to deal with one - dimensional symmetric interplanetary shock dynamics. it should be point out that that initialization of fully self - con sistent 3 - d mhd codes considering the solar - interplanetary - geomagnetic coupled r elations with initial - boundary values at 1r of the global output of solar pl asma and magnetic field using available solar observations is an essential requi rement in space weather operational codes for forecasting purposes
空間災害性天氣的預報是日地物理學界及高科技領域的熱門話題.未來預測太陽劇烈擾動所造成的行星際風暴到達地球空間的狀態勢必藉助于數值方法.淺析了空間災害性擾動事件數值預報存在的問題及未來設想，針對這一目的對一維球對稱問題提出了處理行星際激波的6步求解方法，指出未來空間災害性擾動事件預報模式應是一個基於三維的以真實太陽風為背景自洽建立起來的、以太陽等離子體輸出及磁場全球結構為初邊值、太陽、行星際、地磁因果耦合模式It reflects one ' s growing and the other ' s declining between the interaction of international relationship and ngos, and the behind predictions should be the third sector ' s operating logic because the interaction between nations has to be zooming under globalization. that is, the interaction between international relationship and ngos which only shows each other ' s, but their interaction is under the logic of global operation, so we should include other related rules about global operation, then we can see the general shape of whole pattern. this study has bold predictions about the ruling patterns of future government by partnership, that is, the interaction patterns among different kinds of public or private divisions
非政府組織之所以被稱為第三部門其實是對應第一部門及第二部門而生成的，在國際關系與非政府組織的互動中，除了反應出二者之間一消一長的局勢之外，其背後的基本預設應該是三個部門的運作邏輯，因為國與國之間的互動關系必須被放在全球的運作下進行觀察，也就是說國際關系與非政府組織的互動中雖然呈現的是二造之間互動，但這二者是在全球運作的邏輯之下互動的，因此我們必須納入全球運作的其它相關法則，才能看出整體的模式輪廓。分享友人
