This paper is a study on the theory of fuzzy rough sets.

第一章简单介绍粗糙集的概念，说明了本文研究的缘由。

The system could provide the real-time information on occurrence of more than 60 different kinds of diseases and pests in wheat, corn, rice, potato, sorghum and millet of China as well as diagnosing, knowledge providing and short-term controlling decision for nine kinds of important diseases and insect pests, including powdery mildew, sharp eyespot and scab of wheat, rice blast, rice false smut, potato late blight, aphids, grain gall midge of wheat and corn borer, based on crop resistance, primary level of pests and short-term weather forecast.

本系统能够对小麦、玉米、水稻、马铃薯、高粱和谷子6种主要粮食作物的60余种病虫害进行实时监测、预警、诊断、提供植保知识，能够对年度间同期病情、虫情做出图形比较，可将抽象的预警数据转化成清晰简明的点图式电子地图，直观明了地显示病虫害发生点数及地域分布，可根据品种的抗病虫性、病虫害发生基数和未来天气预报等信息对小麦白粉病、赤霉病、纹枯病、稻瘟病、稻曲病、马铃薯晚疫病、麦蚜、小麦吸浆虫和玉米螟9种重要病虫害做出短期防治决策，系统的运行有助于提高人们对主要粮食作物病虫害管理的科学水平。

We know that the solutions of quadratic, cubic and quartic can be expressed by radicals. As to the solution of the quintic which has became an issue for past two or three hundred years, it was not solved until 1832 a great young Mathematician of French named Galois who recommended group theory that proved a polynomial of degree 5 and over 5 can't be solvable by radicals.

中文摘要我们知道二次、三次及四次的方程式都可以用根式表示，至於五次方程式的解迟迟无法解决，这个问题持续了两三百年，直到1832年，一位法国青年Galois在其决斗前夕，在他的遗书中，这位伟大的青年数学家引进了群的理论，证明了：五次及五次以上的方程式，不可能有公式解。

This study provides genetic evidence that SUN1-telomere interaction is essential for telomere dynamic movement and is required for efficient homologous chromosome pairing/synapsis during mammalian gametogenesis.

我们的研究首次从遗传学上证明了SUN1蛋白和端粒的相互作用对于端粒在动物生殖细胞减数分裂中的动态变化，高效的同源染色体配对、联会以及哺乳动物的配子发生是必不可少的。

First we review the combination of data from life tests, the consideration of this show that a Gamma distribution for the prior of failure rate can be assumed.

首先，介绍了寿命试验数据的信息融合方法，并以此为例，说明了取伽玛分布为指数分布寿命型产品失效率的先验分布的合理性。

Simulation results show that at least 15 photons on average for 59.5 keV gamma ray （~41 Am）.

模拟结果也说明了增加平均光子数对提高空间分辨率的重要性。

Still, says Dr. Ann Garvey, state public health vet at the Iowa Department of Public Health,"We just don't know, we really don't."

爱荷华公共卫生部兽医Ann Garvey医生说，"我们对该事件还不甚明了，真的，我们还没搞清楚。"

Firstly, the gaseous turbulence statistics of single phase flow, derived from PIV data, were compared with documented DNS results, and it demonstrated the feasibility of turbulence measurement using PIV technology.

本文首先比较了采用传统PIV算法测量的单相湍流统计量与文献中直接数值模拟的结果，证明了PIV测量流场湍流量的可行性。

Since the narrative of a Gaulish pilgrim who visited Edessa about 390 contains no allusion to such a picture, we may reasonably conclude that the Teaching of Addai is of later origin.

由於说明了法国人的朝圣者前往埃德萨谁约390不包含任何针对这样的图片，我们可以合理地得出结论，教学中的Addai是稍后来源。

The importance of determining the characteristics of data distribution was analyzed, and an approach to determine the Gauss distribution was presented.

在Matlab实验环境下，采用两组数据集进行了数值仿真，仿真结果说明了本文所提方法的可行性与有效性。关键词：支持向量机；核参数选择；高斯分布

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
