摘　　要：文章介绍了作者在过去５年中在微内核技术上所做的工作．给出了３个算法．①通过将任务调度和线程调度算法相结合的方法，来解决单纯以线程为单位的调度系统的效率和公平性问题；②一个改进的写时拷贝算法，它结合写时拷贝算法和访问时拷贝算法的优点，来解决写时拷贝算法在Ｉ３８６体系结构上的适应性问题；③提出了一个微内核操作系统计时模型，它解决了传统计时算法在微内核系统中计时不准确的问题．Some of the research work which the authors have done on microkernel in the last 5 years are described in this paper. Three new algorithms have been proposed. The first algorithm combines task schedule and thread schedule algorithms together to improve the efficiency of the thread schedule system, it also provides a more fairness scheduling algorithm for microkernel operating system. The second algorithm is an enhanced copy _on _write algorithm, it combines copy _on _write and copy _on _reference algorithms together to make it more suitable on I386 architecture. The last algorithm is a new timing algorithm for microkernel operating system, it solves the inaccuracy timing problem which is caused by traditional timing algorithm running under the microkernel architecture.
