The correlations between the influential factors of the system are first systematically studied by applying the statistic data , then the hazards gather are confirmed 首次运用统计数据对海运系统安全综合影响因素进行较为全面的定量分析。根据分析,确定了海运系统危险状态集。
To support the new collection state - based indicators , a new health data set was added to db2 v8 . 2 that includes collection - specific data like the object name , its state , a timestamp for the alert , and details 为了支持新的基于状态集的集合指示器, db2 “ stinger ”中增加了一种新的健康数据集,其中包括与特定集合有关的数据,如对象名称、状态、警报时间戳以及其他细节。
First we give the conception of multimedia - instance model , which consist of 7 - tuple mi ( s , f , a , a , fi , sv , fj ' 9 , where s is a set of states , which captures a certain structure to store information . f is a set of features , which presents pieces of information of given states , a is a map from sto 2 " . a " is a set of feature - state relations on 2f xs , which reflects the relation between characteristics of state , fi is a set of relations defined on s . which reflects the relation between states 我们首先定义媒体实例的概念,该媒体实例为7元组mi =口,几且, o ,尽sv , 919其中, s是一个状态集,一个状态捕获一个确定的用于存储信息的结构; f是一个特征集,一个特征反映给定状态中一则有意义的信息;允: s 2 ?是一个从状态到特征幂集的映射,反映一个给定状态中所具有的特征; "是一个在2 ? s上的关系集,它反映状态中特征之间的关系;胆是一个在s上的关系集,反映状态之间的关系; sv是一个状态变量集; fv是一个特征变量集。
As a result of the heightening of mechanical operation speed and the application of new materials and new structures , the nonlinear dynamic behavior in rotating machines is becoming increasingly outstanding and important . nonlinear dynamic phenomena in rotating machines cant be described , explained and predicted by rotordynamics based on linear system theory . along with the deepening and permeating of nonlinear scientific research , the nonlinear vibration of rotor systems has become an attractive field in recent years . from a point of view to set up the distinct corresponding relations between vibration states and failures of rotating machines , main advances in the research of rotor nonlinear vibration are summarized , and typical nonlinear dynamic phenomena and their forming mechanism are also summed up in the paper . the aim of the paper is to enrich the diagnostic knowledge base of rotating machines . 55refs 由于机械运转速度的不断提高和新型材料、新型结构的推广应用,旋转机械的非线性动力学行为日显突出和重要.基于线性系统原理的转子动力学理论与方法难以对实践中出现的丰富的非线性动力学现象作出准确的描述、阐释和预测.近年来,随着非线性科学研究的深入和渗透,转子系统非线性振动已成为应用力学和机械工程领域的研究热点之一.从有利于建立旋转机械振动状态集与故障集之间的映射关系出发,综述了近年来转子系统非线性振动研究的主要进展,总结了转子系统中出现的典型非线性动力现象及其产生机理,目的在于丰富旋转机械故障诊断知识库.参55
