结合粗糙集理论和k最邻近方法提出综合评价的混合算法，算法可以充分结合主客观因素，计算简单，在实际应用中具有可行性。

Rough set theory emerges as a powerful tool for dealing with the vagueness and uncertainty of facts,which has been widely applied in many fields such as artificial intelligence and data mining.

粗糙集理论是一种处理模糊和不确定性知识的数学工具，在人工智能及数据挖掘等众多领域已经得到了广泛的应用。

There was no obvious interdiffusion and reaction between WN〓 thin films and GaAs substrate.

目前对Ni〓Al合金的动态脆化研究因成分，组织状态和试验条件等方面的因素，实验结果还存在不少矛盾，理论分析亦比较粗糙，对一些关键问题的本质尚有争论。

In additional, the roughness and atomic interdiffusion between the layers will also cripple the GMR effect and application characteristics.

最后，界面粗糙度、层间原子扩散等微结构缺陷的存在对器件稳定性的影响也变得明显。

This paper introduces a new interferometer for measuring the surface roughness based on the principle of differential polarization interferometry.

提出了一种表面粗糙度测量的新方法。

The bidding for tasks between the task agent and the resource agents is described in terms of acquaintance set, invitee set, bidder set and bid-winner. The decision table is built with the attributes of tasks and the attributes of cost, quality, load and time for resource agents to accomplish the tasks.

通过相识集、招标集、投标集和中标者等概念描述了任务Agent和资源Agent间协商过程模型，基于任务属性和资源Agent完成任务的成本、质量、负荷和时间等属性，构造粗糙集的决策表，获取规范的调度决策和任务分派规则知识集。

If iolite is not cut from exactly the right direction, no matter the shape of the rough, its colour will not show to its best advantage.

如果不是删iolite正是正确方向，无论造型粗糙、它的颜色，不会做最佳优势。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
