Security analysis for two quantum key distribution protocols was presented by using EPR pair and complete Bell-state measurements. It is also shown that those two protocols are totally equivalent from the point of view of the topological structures on how to measure the corresponding qubits at random.

对两个使用EPR对和Bell测量基的量子密钥分配协议的安全性进行了分析，从测量不同位置的量子比特的拓扑结构出发，证明了这两个协议的等价性。

The fidelities of the system surge periodically from 0 to 1 for the etceteras Bell state at original time when average photon number of two-mode entangled coherent states cavity fields are very small.

对于好腔，若原子初始时刻处于相干保持态，系统保真度呈指数单调衰减；若原子初始时刻处于其余Bell态之一，系统保真度呈指数振荡衰减，且随着腔场初态的平均光子数的增加，系统保真度的振荡频率增大，振幅减小。

The chapter 3 investigates the constructive method which means that many combinatorial numbers, such as Stirling number, Bell number, harmonic number, Fibonacci number and the number of derangement, are represented to moments of some random variables. This method is used in the computation of combinatorial sums, discovery and proof of combinatorial identities.

第三章研究了构造性概率方法，即一些常见组合变量(以后统称组合数为组合变量)的概率表示，诸如Stirling数、Bell数、调和数、Fibonacci数、错排数都可以表示为一些随机变量的矩，这些概率表示可以用来研究组合和式的计算与恒等式的证明。

Bell's paralysis ; the acupuncture therapy with finger ; Functional exercise

Bell's面瘫；指针疗法；功能训练

The silicone rod is an effective material for use in frontalis suspension in treating severe ptosis. Elasticity and ease of adjustment are favorable characteristics of using a silicone rod in frontalis slings procedure to correct severe ptosis with poor Bell's phenomenon.

silicone rod frontalis slings是用来矫正眼瞼下垂病人很有效的方法，而且因为这材质的弹性及方便调整的特性，对於严重眼瞼下垂而且Bell's phenomenon不良的病人，其手术效果及术后减少exposure keratopathy的严重程度，均比传统使用之材质好。

Explains Genevieve Bell , an anthropologist and director of the user experience group in Intel's digital-home group, people have extremely strong bonds to their TV sets."Any effort to add internet content needs to be just as simple and not interfere with the experiences and behavior patterns the users enjoy."

人类学家、英特尔数字家庭工作组用户体验组的负责人Genevieve Bell解释说："人们对电视有强烈的依赖，任何想把英特网加进来的努力都需要尽可能的简单化，不要干扰用户喜欢的那种体验和行为模式。"
