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。

访问概率
1.
In the paper,a new method of caculating disk access time was described by introducing random variables and access probability,which has advantages of being more accurate and practical.
传统的磁盘访问时间由磁头寻道、盘片旋转和磁头读写3部分累加得出,通过引入随机变量和访问概率等数学工具来计算磁盘访问时间,具有精确度更高、实用价值强等优点。
补充资料:调频
载波的瞬时频率按调制信号的变化而变,但振幅不变的调制方式。载波经调频后成为调频波。用调频波传送信号可避免幅度干扰的影响而提高通信质量。广泛应用在通信、调频立体声广播和电视中。
