Associativity specifies how to group operators at the same precedence level. 结合性规定了具有相同优先级的操作符如何分组。
Thermoelastic Infrared Image Safe Testing System is a key item of the national science instrument, and passed technique identify in Dec. 29, 2002. The experts uninfected that is an original creativity technique and international precedence level. 国家科学仪器重点攻关项目热弹性红外图像安全检测系统于2002年11月29日在北京通过技术鉴定,专家一致认为是原创型,具有国际领先水平。
By the method of Delphi and precedence chart, the all level indexes, index power value and contents of the basic index of the whole system were confirmed. 利用Delphi法及优序图权重法对指标体系预案进行了专家咨询,确定了指标体系的各级指标、指标权值及基础指标内涵。
The PRED algorithm could reflect the relative precedence of packet, and adjust the service level of packet adaptively. Thus, it is an ideal packet dropping algorithm for DiffServ model. PRED算法体现了分组的相对优先级,并能自适应地对分组的服务级别进行平滑地升级或降级,因而很适于作为DiffServ网络中的分组丢弃算法。
The article explains the model of network control system and the model of networking protocol that is analyzed, puts forward two kinds of schemes of selecting precedence level, the first uses fixed admittedly wanton interval, the second uses voluntarily divided interval. 表述了网络控制系统的模型和要分析的网络协议的模型。提出了两种选择优先级的方案,第一个用固定的任意间距,第二个用自动划分的间距。
