probability n. 1.或有;或然性。 2.【哲学】盖然性〔在 certainly 和 doubt 或 posibility 之间〕。 3.【数学】几率,概率,或然率。 4.或有的事;可能的结果。 5.〔pl.〕〔美俚〕天气预测。 What are the probabilities 有几分把握? The probabilities are against us [in our favour]. 趋势对我们好像不利[有利]。 hit probability 命中率。 in all probability 很可能,大概,多半,十之八九。 probability of (missile survival) (飞弹不被击落的)概率。 The probability is that ... 大概是…,很可能是…。 There is every probability of [that] ... 多半有,多半会。 There is no probability of [that] ... 很难有,很难会。
In this thesis , the handover and channel assignment schemes in leo - mss are introduced and discussed deeply . on the basis of the integrated consideration on handover , channel allocation and resource reservation , the appropriate handover and allocation techniques are proposed so as to reduce the call blocking probability and handover failure probability . thus , the proposed schemes can improve the channel utilization efficiency and the system performance 本文对低地球轨道( lowearthorbit , leo )卫星通信系统中的切换与信道分配策略作了较为深入的研究,将切换与信道分配、资源预留等因素综合考虑,采用合适的切换算法来降低呼叫阻塞率和切换失败率,提高资源利用率,从而改善系统性能。
In addition , a model is presented to analyse the blocking probability problem . by using alternative routing method with adaptive element , the new dynamic rwa algorithm guarantees low blocking probability a nd high tolerance of the network mistakes . a shorter delay time is achieved by considering the first k links information to find a available route 论文给出了分析rwa算法阻塞率的方法,提出的新rwa算法中路由采用了优化的含自适应成分的替代路由法,该算法既保证了网络低阻塞率的要求,又具有一定的网络容错能力,利用前k条链路信息的技术使得算法运行时间更短,在波长分配的问题上,算法应用优先级的方法以满足不同优先级别业务的需求。
Next , a novel priority - based wavelength assignment algorithm in all - optical networks with partial wavelength conversion is proposed , based on link independent assumption and the method of calculating the network the blocks probability . it improves the routing and wavelength assignment presented by others . this algorithm fits the demand of different business for asking the grade of corresponding different services in the modern all - optical network than the original algorithm 其次研究了部分波长可变wdm网中支持优先级的波长分配问题,以及在此网络中网络阻塞概率的计算;基于链路波长占用独立性假设,改进了在部分波长转换wdm网中已有的rwa算法,提出了一种支持优先级的动态波长分配算法,该算法保证了较高优先级的光路建立请求具有较低的阻塞率,比原有算法更加适合现代光网络中不同业务请求对应不同服务等级的要求。
