Linux最初是作为一个通用操作系统,其设计的基本原则是尽量缩短系统的平均响应时间并提高系统的吞吐量。尽管Linux2.6中提供了一些实时处理的支持,如可抢占内核、O(1)进程调度算法等。但是,Linux的实时性能还是比较差,不能保证实时任务的响应时间。本文简单介绍linux2.6内核调度算法的缺陷;在EDF算法基础上,提出了一种新的实时调度算法SBD(Scheduler Bsaed on Deadline)。实验结果表明,改进的Linux内核的实时性能比标准的Linux内核有较大的改善。
Objective:To study pulse taking of teaching material of traditional Chinese medicine diagnostics.Methods:On the basis of literature of pulse taking,to analyze subsection origin and development of cunkou pulse,and discuss pulse manifestationfeatures of scattered pulse,sugring pulse and hesitant pulse,and misusage of concurrent pulse,besides,indicate needed improved content of teaching material.Results:Teaching material should add subsection origin and development of cunkou pulse,describe pulse manifestation features accurately,and avoid misusage of concurrent pulse.Conclusion:Through modifiying and improving pulse taking of traditional Chinese medicine diagnostics,to ensure comprehensive accuration of knowledge for students,and develop teaching quality of traditional Chinese medicine diagnostics.
