data migration

Page migration is an optimization policy to exploit data locality in distributed shared-memory systems but hindered by its temporal and spatial cost and its architectural dependence.

页迁移是分布共享存储系统中动态开发数据局部性的一种优化策略，但体系结构相关性及时空开销限制了它在实际系统中的应用。

On the basis of leaching experiment data, Darcy law and Solute migration as basic equations, we simulates a time-dependent porous media which produced by gravity flow of the basic model with the help of COMSOL software.

以浸出实验数据为依据，达西定律、溶质迁移扩散为基本方程，借助COMSOL软件，建立了与时间相关的多孔介质中由于重力作用产生流动的基本模型。

Whole volumes can be added and ( with appropriate data migration ) removed.

全卷可以被增加 ( 通过适当的数据转移 ) 和删除.

Birthplace data are only the crudest indicator of actual migration paths.

出生地信息只能非常粗略地显示实际移民过程。

Prestack migration method presented in this paper should be developed to apply in observational teleseismic P waveform data, to study the inhomogeneity of crust and upper mantle.

对本文所提出的接收函数叠前偏移方法作进一步的发展，可以用于实际的远震体波波形数据，在揭示地壳上地幔结构的横向非均匀性研究中，具有颇为广阔的应用前景。

Data migration is a mapping between source database and target database.

数据迁移可以看作是实现从源数据库表到目的数据库表的映射.
