  1. We examin e the generation of bell state in bose - einstein condensates of two interacting species trapped in a double - well configuration analytically and the density of probability for finding the entangled bell state is given. we find that the oscillation amplitude of the probability of density for finding the entangled bell state becomes greater as the ratio of the interspecies interaction strength and the tunneling rate increases, moreover the self - interaction strength of the component a ( b ) has no effect on it. also we use the time - dependent su ( 2 ) gauge transformation to diagonalize the hamilton operator, obtain the berry phase and analytically the time - evolution operator

    此外我們還研究了在雙阱玻色-愛因斯坦凝聚中糾纏態的演化，研究發現隨著組分間相互作用和隨穿率的比值的增加系統演化到bell態的概率變大，而且組分自身內在的相互作用對形成bell態的幾率沒有影響；並且用含時su （ 2 ）規范變換對角化哈密頓量得到了系統的berry位相和時間演化算符，並研究了量子隨穿過程。

    本質上， dm演算法是一種啟發式的貪心優化演算法，它採用局部搜索方法能逐步逼近地為預先定義的目標函數找到一個近似最優解。
  3. [ b ] bell [ / b ] in ancient times all over the world, it was believed that evil spirits could put up with just about anything except the clanging of a bell

    鐘[ / b ]古時候，世界各地的人們相信邪惡的靈魂能夠忍受一切，但就是不能忍受丁丁當當的鐘聲。
