摘　　要：对虚拟计算机数据存储空间的稳定性进行优化,可以有效缓解数据的存储压力。对数据存储空间的稳定性优化,需要根据历史数据和当前数据的交界区域,得到数据存储空间稳定性优化阈值。传统方法通过给出数据存储的约束条件,得到数据存储的理想状态函数,但无法得到存储空间优化阈值,导致优化精度低。提出基于预分块和滑动窗口的虚拟计算机数据存储空间稳定性优化方法。融合于动态指针方法给定实验室系统数据流无穷序列,划分出数据变动区域和非变动区域,提取数据中的冗余元素,计算出重复数据存储率,采用滑动窗口给出上限值与实际值之间的差值,根据历史数据和当前数据的交界区域,得到存储空间稳定性优化阈值,完成对虚拟计算机数据存储空间稳定性优化。实验证明,所提方法数据存储安全性高,极大地提升了计算机存储空间,保障了虚拟虚拟计算机灵活性和稳定性。An optimization method for stability of data storage space of virtual computer based on beforehand bloc- king and sliding window is proposed. The infinite sequence of data flow of laboratory system integrated with dynamic pointer method is provided, and variable domain and invariable domain of data are marked out, then redundant ele- ment of data is extracted. The rate of repeating data storage is worked out, and the sliding window is used to provide difference value between upper limit Value and actual value. Moreover, the optimization threshold of the stability is obtained according to boundary area between historical data and current data. Thus, the stability optimization is com- pleted. Simulation proves that the method has high security of data storage. It extends storage space of computer ap- parently and ensures flexibility and stability of virtual computer.
