If the frequency distribution of these inputs can be calculated , measured , or even estimated , the frequency response can be used to determine their effects upon the system output 如果这些输入的频率的分布是可计算、测量、甚至可估计的，则频率响应可以用来决定系统输出的效果。
Several bsos are created to enable the users , being the owner of the system , to decide what they require the system to do under the effect and limitations of different constraints 由于用户是系统的拥有人，因此须为他们提供多个业务系统选择，让他们能决定系统在各种限制之影响和束缚下，需要执行甚么工作。
The electron wavefunction which contains both frequency and strength of the external field as well as the sizes of the quantum wire is obtained , with which the time - dependent transport property of the system can be determined 此波函数包含了外场的频率和强度以及量子线的几何参量，由此可研究决定系统与时间有关的输运性质。
This is especially a requirement for considering systematic real - time character . according to examines the result judges each function module in turn whether appears the breakdown , or will lead to the whole system appear unstable state . software notes the fault ; system monitor read the notes 根据检测结果依次判断各个功能模块是否出现故障,甚至导致整个系统出现不稳定的状态,并随时将检测故障的数据告诉监控人员,由其决定系统是否需要继续工作。
Using a real the regional health enterprise as a model , this paper mtroduces a management information system ( mis ) under the environment of novell lan with foxpro database language . according to the direction of software engineering , the system was accomplished by the mean of structured system analysis and design and implement . in the part of system analysis , the feasibility of the system is analyzed , the goal and the demand of the system is determined and the logic model of the system is set out as well 本文以一个实际部门为模型，在novell局域网环境下用foxpro数据库语言实现了社区卫生运营管理系统，在系统实现过程中，以软件工程思想为指导，按照结构化系统分析、系统设计及系统实施的方法来实现；在系统分析中，运用结构化系统分析工具对系统进行了分析，提出系统的可行性，决定系统的目标及需要，主要根据系统调查阶段所获取的资料分析需求，提出系统的逻辑模型。
For the exists of false alarm and trying to release the system burden , and for the exist of what we call base - rate fallacy , we try to construct a security adaptation system for the primary ids . the primary ids decide the criticality of the network environment , and give the order on switch the detection policy to the secondary ids 由于误报情况的存在和为了减少系统的负担，以及称之为基率佯缪问题的存在，针对于主ids ，本文构建了一个自适应入侵检测方法，由主ids决定系统所处的网络环境的恶劣程度，并向从ids下达指令转变相应的策略。
