Yet his first two books , “ arabian sands ” , about his crossing of the empty quarter , and “ the marsh arabs ” , about southern iraq , have a terse [ 5 ] brilliance about them 不过，他的头两本著作，一本叙述横穿阿拉伯半岛南部沙漠“空白之地”的《阿拉伯沙地》和另一本描写南伊拉克的《沼地阿拉伯人》 ，简洁明了地记录了他光辉的旅程。
Because of the complex swelling mechanism and various factors which influence the dilatational strain , to find out the major factors and to establish an accurate and simple swelling constitutive relationship is the key to swelling rock research 膨胀岩的膨胀机理复杂，影响膨胀变形量的因素繁多，找出其中的主要因素，建立合理准确、简洁明了的膨胀本构关系是膨胀变形研究的关键。
The core content and the most characteristic in the paper is that timber demand curve amend method ( tdcam ) is designed and advanced to calculate environmental shadow price . tacam buildups a concise and clear frame model of economic and environmental theory analysis 论文的核心内容和最具特色之处是对木材需求曲线修正法进行改进和完善，构建了一个简洁明了的环境?经济的分析框架模型。
In addition , the whole programme is based on c language , this makes the programme concise , intelligible , and understandable , all of these advantages contribute to the management and maintenance of the programme , what is more important is that it can be transplanted easily 另外，全部程序采用c语言编程，这使得程序简洁明了，可读性强，有利于程序的管理和维护，更重要的是可移植性好。最后，对航迹仪的跟踪过程进行了仿真。
The control panel of this preprocessing system is simple and convenient . the friendly interface between computer and human allows the users easy to complete all the preprocessing operations , including the model ’ s meshing , the setup of the material parameter and welding processing parameter , the initial conditions and boundary conditions ’ definition etc , preparing for the simulation subsequently . so any operator with lack of knowledge in fem or english can finish the welding simulation during using this preprocessing system 该前处理系统界面简洁明了,操作简单方便,用户按照该系统界面进行操作即可完成模型网格划分、材料性能参数的输入、热源模型选择及焊接参数的输入、以及初始条件和边界条件的设置添加,为模拟计算做好准备,从而使工厂的一般技术人员也能完成焊接过程的模拟计算。
To be dealed agaist extended data , this thesis has improved on and come true arithmetic of time sequence model , and amended conventional decision tree arithmetic , introduced the decision tree arithmetic for extended data , namely threshold value control approach . according to threshold value and concept hierarchy , threshold value control approach can set up the concise and statistic classification tree . at the same time , based on the theory of the concept lattice , this thesis introduces the arithmetic of mining association rules based on quantified concept lattice reduced by uncertainty coefficient 针对泛化后的数据，本文改进并实现时间序列模式发现算法；修改了传统的决策树算法，提出了一种适合于泛化数据的决策树构造算法：阈值控制法，阈值控制法通过阈值和概念层次的控制，可以建立简洁明了、具有统计意义的分类树；在概念格理论基础上提出了基于不确定系数法挖掘关联规则的算法。
Using powerpoint , this cai narrates briefly and legibly the motive principle equipment and the operation approach when narrating the operation approach in the way of navigation , the software uses words photos of practicality cartoon and combines them organically , such makes the effect be vivid and clear 该软件采用powerpoint制作，简洁明了地叙述了实验的目的、原理、设备和操作步骤。实验步骤的叙述采用了文字、实物照片、动画等形式相结合，以导航的形式进行，既生动又清晰。
This paper , based on the collection of many other models , aims to make a further research on the model of the customers ' purchasing behavior and puts forward a complete and easily impraved model which comforms to the logical behavior and psychological law of the customers and then gives a detailed analysis 本文尝试在集众家之长的基础上，对消费者购买行为模式进行进一步探讨，提出既完整、又简洁明了，符合消费者的购买逻辑思维习惯和心理规律的改良模式，并对有关内容作了较详尽的说明。
