Based on the theory of large eddy simulation and the method of VOF , the initial breakup process of fuel liquid jet, which eject from the nozzle exit at the time scale of micro-second level, is investigated. The mechanism of primary atomization is analyzed, and the initial breakup model of liquid jet is presented. By modeling and numerical simulation of atomization for a diesel nozzle under the given conditions, the initial umbrella-like spray shapes are obtained, which fits better with the experimental results. Meanwhile, the droplets secondary breakup process, such as leeward RT breakup, dumbbell-like breakup and droplets coalescence, etc. are exhibited visually.

基于大涡模拟LES理论和VOF方法，考察了燃油喷雾初始时刻即时间尺度为微秒级的液柱破碎过程，分析了初始破碎的机理，给出了该时间尺度下液柱初始破碎过程的模型；通过对一特定条件下的柴油机喷油器的建模和喷雾过程的大涡数值模拟，获得了液柱初始时刻"伞状头部"的喷雾形态，所得计算结果与相应的试验数据符合较好；数值模拟还直观地展现了液滴背风RT破碎、哑铃型破碎以及液滴的聚集融合等液滴的二次雾化过程。

That is an even more personal manner in this research. With attitude of the"flaneur" to go to the interpretation of the city's cultural observation.The scale of the picture book from huge scope to small, gradually in-depth the life of Taipei City experience. It displayed the "megacromic and microcosmic things" in this two scales of picture book. Finally, I arranged all images and let it become a personal thinking for interpreting of the experiences the life of Taipei.

本论文试图透过自身熟悉的沟通语言─绘本，作为个人对於台北城生活经验的认知书写，以自我个人化的第一人称描述我所见、所感觉到的台北城，同时以「步行的漫游者」作为空间实践的态度，并透过尺度上由大变小的差异角度呈现不同的绘本观点，这样的绘本过程，对於自身是一种深入台北城生活的方式，同时「漫游者」的态度更可以反应一种文化观察的眼光与反思，呈现出两种差异尺度的绘本─巨观与微观，最后将这些图像予以安排成一个观看城市的方法与态度。

Also, in the decoration sometimes need some decorative wire feet, cheek, floriation so on, but in some home-improvement in the deliberate pursuit of large-scale collage Dingjiao Xian, lumpy Door-line, ultra-scale round roof lines, the consequences of this decoration is that it reduces the room space, but also elegant and generous Qiyun lost, but also the loss of a family should have a warm decoration taste.

还有，在装修中有时需要一些装饰性的线脚、贴脸、花饰等，但在有些家装中刻意追求拼贴大尺度的顶角线，粗笨的门套线，超尺度的圆型顶棚线，这种装饰所产生的后果是，既缩小了居室空间，又失掉了典雅大方的气韵，还丧失了家庭装修应有的温馨品位。
