Therefore how to select theminimum character sets in guaranteeing the incurrence of system status approval isimportant, namely to reduce the character, lower work loading and reduce the uncertainfactors in the conditions of guaranteeing diagnostics accuracy. And in fact these are theproperly research contents of rough sets.

因此，论文介绍了粗糙集的基本理论，阐明了基于粗糙集观点的知识表达方法，根据水轮机调速系统故障特征的复杂性和不确定性以及粗糙集决策表白动约简、搜索的基本方法，提出了利用粗糙集决策表约简规则进行水轮机调速系统故障诊断决策方法及具体步骤。

I am a loyal customer of Jasmin Skincare products. I started to use Jasmin about a year ago.

我本人一直是简诗美护肤品的忠实客户，我大约在一年前开始用简诗美的产品。

When I first heard of Jasmin is an Australian Organic Skincare range certified by OFC, I had a mixed feeling of surprising and regret: I was surprised that there are organic skincare products of such premium quality available in Chinese market, I was regret that I did not know Jasmin early.

当我第一次听到简诗美是一个来自澳大利亚有机护肤品系列的品牌并通过了澳洲OFC认证的时候，我当时的心情就是又惊讶又后悔：我之所以惊讶就是因为在中国市场居然会有如此一流的护肤品牌，我之所以后悔是因为我怎么就不能早一点接触简诗美这个有机品牌。

This method is based not only on the intuition and objectivity of the Karnaugh map but also on the mature rules of single-output functions.

以实例说明了共卡诺图化简法的应用，展示了该方法化简多输出逻辑函数简洁明快的特色。

With the computer assistance Karnaugh Map the method of the logic function will overcome the weakness of the manual simply, making turn alone more convenient and valid.

而用计算机辅助卡诺图来化简逻辑函数的方法将克服人工算法的缺点，使化简更方便有效。

But turn alone with the calculator assistance Karnaugh Map the method of the logic function will overcome the weakness of the artificial calculate way, making turn alone more convenient and valid.

而用计算机辅助卡诺图来化简逻辑函数的方法将克服人工算法的缺点，使化简更方便有效。

The prerequisite of the correct use of karnaugh map is to full in the map with the given logic function correctly. Karnaugh map can be used to transform logic function into various simplest expressions and check the race and hazard of logic function. It has a wider range of important applications in the analysis and design of combinational logic circuit and sequential logic circuit.

正确运用卡诺图的前提是把给定的逻辑函数正确填图，可以利用卡诺图将逻辑函数化简为各种最简表达式；可以用来检查逻辑函数的竞争冒险等；在组合逻辑电路和时序逻辑电路的分析与设计中更有广泛的重要应用。

The concepts of the S-simplest form of a seminorm family P and the P-reflexive locally convex space are introduced. The seminorm family P and its every S-simplest form generate the same locally convex separated topology on X are proved.

引入半范数族P的S-最简形式和P-自反局部凸空间的概念，证明了半范数族P和它的每一个S-最简形式都生成X上相同的局部凸拓扑。

For better radar emitter recognition,a study is carried out in this paper on the attribute reduction algorithm,which is based on discernibility matrix and logical operation in Rough Sets.

为准确解决辐射源识别问题，研究了粗糙集中基于可辨识矩阵和逻辑运算的属性约简算法，对决策表进行约简，减少了属性个数；并建立了一种基于粗糙集数据处理的雷达辐射源识别模型。

It holds that graphic simplification method is still practically applicable for simplifying high variable logical function.

本文观点与此不同，认为图形法对于高变量逻辑函数的化简仍然具有实用价值，同时提出了用图形法化简高变量逻辑函数的具体方法。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
