基础心率,基础心搏率
控盘系数

The performance metrics , access latency , throughput , hr hit ratio and bhr byte hit ratio are analyzed and discussed . simulations show that compared with caching only model , iwpcm can further improve the throughput , hr and bhr efficiently and reduce the access latency . the performance evaluation based on the spn model can provide a basis for implementation of web prefetching and caching and the combination of web prefetching and caching holds the promise of improving the qos of web systems
对于缓存命中率和字节命中率等性能指标，使用基于一阶ppm prediction by partial match预测算法，通过四种典型的缓存替换策略gdsf greedy dual size frequency ， gdsize greedy dual size ， lfu least frequently used ， lru least recently used在仅缓存模型和一体化模型中的应用验证了一体化模型比仅缓存技术具有更好的性能。
