By using the properties of part matrix elements in N1 , and by looking for positive diagonal matrix factors, we present some new sufficient conditions of generalized strictly diagonally dominant matrix and improve the recent results.

第二章在行非严格对角占优集N_1划分为N_1~(1)与N_1~(2)的直和N_1~(1)⊕N_1~(2)的条件下，利用下标在N_1上部分矩阵元素的性质，寻求正对角矩阵因子，给出了广义严格对角占优矩阵的几个新的充分条件，同时改进了近期的一些结果。

Thirdly, it collect the ship mechanical accidents of the main Chinese shipping company ,and then sorts them out as four items: equipmentname, typical trouble, monitoring parameters, consequence; uncovers the internal relation among man,machine,circumstance and management, establishes a relation database between condition monitoring and typical trouble for the engine-room equipments ; refering to the SMSC-2000 marine engine-room simulator in Shanghai Maritime University, it divides the engine-room system into eight subsystems, designs the monitoring interfaces which is marked with the monitoring parameters, detects the running engine-room machine by use of trouble analysis and information syncretizing, and builds up the condition monitoring system of engine-room machines.

其次，对近十几年来的国内主要航运企业中的重大船舶机损事故搜集，按设备名称、典型故障、监测参数和后果进行整理、分析和总结；揭示了船舶机损事故中人、机、环境和管理之间的内在联系：以我院的轮机模拟器SMSC-2000参照，把船舶机舱各设备划分为8大系统，确定了标注有监测参数的各系统简图，并运用信息融合和故障诊断技术对机舱重要设备的运行状态进行监测，建立起机舱设备的运行监测系统。再次，提出了以人、机、环境和管理四大安全要素为评估指标，给出了四者间的权重系数计算方法，提出了线性加权综合模型来最终对机舱设备进行安全评估，得出安全等级，指导船舶管理人员进行管理。

With the increase in tempo, the angle of hands away hail no significant change, but in 4 tempo for 3 athletes, their angle of entrance always greater than their angle of run, and their left angle of hands always were greater than right, it means that their left extent of hands away were longer than their right.

转桨角的变化幅度不大，但在四种桨频下，3名运动员的入水角都大于出水角。3名运动员的左转桨角比右转桨角大，意味着3名运动员左手桨叶的划幅比右桨大。

Cy Twombly uses a combination of charcoal, colored pencils, chalk and oil paint in his works; sometimes he also incorporates wavy, flowing, scribbled text. But Ye Yongqing uses an "eyebrow pencil" to portray abstract lines and points to form a poetic visual language. His latest paintings further expand on this. He created seven abstract paintings of an identical composition, method, symbol and style entitled Broken - Heart. These paintings vary in either background color or color of the lines.

汤布里在绘画中并用炭笔、彩色铅笔、粉笔和油画颜料，还借用文字抽搐涂抹飞动书写，而叶永青的绘画则用"眉笔"一点一划描绘出抽象的线条，构成了诗意的视觉语言，尤其是他最近的绘画把这样的观念性做了进一步延伸，他完成了七幅同一构图、同一方法、同一符号、同一风格的抽象绘画《伤·心》，它们的不同表现为：要么每一幅画中的底色不同，要么每一幅画中符号描绘的颜色不同。

As when Bands [ 675 ] Of Pioners with Spade and Pickax arm'd Forerun the Royal Camp, to trench a Field, Or cast a Rampart.

不久，那座山被他那队人马凿开了，划开一道很大的伤口，挖出黄金的肋条。

Based on the "Structural Holes" theory and the concept of "Bridge",combined with the characteristics of the sharing, divide the "Bridge" into five types. Discuss the role of the five types in sharing; Based on the results of the UCINET analysis, express the coordination role of coordinator, and give a optimization way of the inside network; Divide the broker into two types, and make a description of the two types' function in details; Integrate the discussion of gate keeper and representative, and descript the different function of them on the same system; Descript the function of the Simmel model,and illustrate the bad effect of the model and give measures to avoid that.

在简述"结构洞"理论和"桥"的概念的基础上，结合科技资源共享的特点，把"桥"划分为5种类型；对不同类型"桥"在共享中的作用进行论述；基于UCINET分析结果说明协调者的协调作用，并提出内部人际网络优化方法；对中介者进行再次分类，并详述两种模式在科技资源共享中的功能实现；将守门人与发言人综合论述，描述在同一个体系下实现两者不同作用；对齐美尔连带的作用进行论述，对其可能产生的负面影响进行说明并给出相应的避免措施。

No clear-cut distinction can be drawn between professional and amateurs inscience: exceptions can be found to any rule.

科学领域的专业人员和业余爱好者之间划不出泾渭分明的界线：因为任何规则都有例外。

Biodiversity is one of the front areas of current biological research. The mechanisms of the formation, spatial distribution pattern, conservation and utilization of biodiversity have been an important area of biological and environmental research. In this study, through analyses of data about plant diversity, animal diversity, geographic factors, climatic factors, and energy factors by use of GIS software, statistic software and ecology software, the mainland of China was divided into 241 small districts of 2° by 2°. The environmental factors in each district were analyzed and isopleth maps of environmental elements were depicted.

生物多样性是当今生物学研究的热点问题之一，生物多样性的形成机制和分布格局以及保护利用问题一直是生物学和环境科学所研究的重要内容，本文由此出发，以中国陆地为研究区域，通过植物多样性数据、动物多样性数据、地理因子、气候因子、能量因子等资料，利用MAPGIS、MAPINFO等GIS软件，SPSS、DPS等统计学软件以及CANOCO等生态学软件，将中国陆地划分为241个小区，分析了各区内的环境特点，统计了各区内生物多样性的数量，并绘出环境因子等值线图，中国陆地种子植物科、属、种，裸子植物种、蕨类植物种、兽类、鸟类、爬行类、两栖类种数的等值线分布图，对中国陆地植物、动物多样性现状、分布格局及与环境因子的关系进行了研究。

THE ivory-billed woodpecker is not large, as birds go. It is about the size of a crow, but flashier. Its claim to fame is that, though it had been thought extinct since 1944, a lone kayaker spotted it about two years ago, flying around among the cypress trees in the Cache River National Wildlife Refuge.

象牙喙啄木鸟与普通的鸟一样，体形不是很大，跟乌鸦差不多，但羽色较亮。1944年以来人们一直以为它已经灭绝，但大约两年前，一个划着小船的独行客在凯奇河国家野生物保护区的柏树林中发现一只啄木鸟正在四处飞翔，因此，这种鸟就出了名。

You stand there, a mere body or lay figure, and they still go on delicately ripping out sleeves and collars with their little penknives, pinning and unpinning, and making mysterious signs with chalk, and you have long ceased to understand what all the bother is about.

你站着不过是一具肉身或一个人体模型，裁缝们却小心翼翼地用小折刀扯出做袖子和领子的布，别针别上又取下，还用粉笔划些神秘的记号，而你老早就纳闷如此煞费周章意义何在。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.

提出了用测地线方程、曲面上两点间短程线来计算膜结构曲面测地线的方法，同时，采用测地线间垂线的中点连线和用无约束极值法进行空间条状曲面近似展开的分析。
