To design the N-M scheduling strategy, this thesis analyses the gird system's availability models, based on this jobs, the N-M scheduling performance models are designed.

为了设计和分析n -M调度策略，本文分析了网格资源的可用性概率分布模型，在此基础上，为N - M调度策略建立了性能模型。

Meanwhile, the ash is rich in certain elements, which are critical to modify the elements constitution of soil and increase the availability of N and K in usual situation.

根据目前研究情况，木灰肥用不但实现了元素循环，而且一定程度上提高和改良了土壤特性。
