1) frequency restriction
频率限制
1.
The working features and frequency restrictions of SFC starting under two operation modes are analyzed, which are pulse switching mode with low speed and synchronous mode with high speed.
分析了SFC启动同步电机低转速运行(脉冲切换方式)和高转速运行(同步方式)的工作特点、频率限制。
2) minimum freguency limit
最低频率限制
3) sample frequency limit
采样频率限制
4) frequency selective limiter
频率选择限制器
5) Access Frequency Restrict
访问频率限制
1.
To prevent the public interfaces from being over-invoked, this paper proposes an Access Frequency Restrict Service (AFRS) Model, which abstracts various access frequency restrict logic, recording the invoking-time and interval by key-business-pair.
为防止开放系统的公共接口被过度调用,本文提出一种面向系统内部的访问频率限制服务轻型模型,并给出泛型键值索引、频率约束算法等关键技术实现。
6) limiting frequency
极限频率
1.
Results show that the movement limiting frequency is 253 Hz,thus provide theoretical guide for the frequency setting value of ageing and testing experience,to avoid the abnormal movement with incorrect driven frequency.
分析了电控共轨供油泵进油电磁阀衔铁组件的运动过程,使用Simulink软件对衔铁吸合和回落过程运动时间进行了模拟计算,得到电磁阀部件运动的极限频率为253 Hz,为电磁阀部件在磨合和试验过程中控制系统设定的控制频率提供了理论依据,避免了因输入频率过高而导致的电磁阀部件运动不正常。
