进一步，我们给出了分叉曲线及其沿分叉曲线的上部分支三个Rayleigh数对应的对流图案的垂直速度场，流线，温度场，浓度场和Shadowgraph强度的等值线图。

This kind of house absolutely abandons the European and American styles in the architectural design but employs more Chinese traditional residential elements, such as the pitched roof, wall, blue tile and white wall. What's more, especially in the large spatial layout, this building advocates the closed and semi-enclosed spatial arrangement in response to the psychological characteristics of Chinese people, restraint without showiness. However, the interior life circulations without exception absorb the European lifestyle to show the life philosophy and value orientation.

这类住宅的主要特点是在建筑设计上摒弃了完全欧美化的做法，而采纳了较多中国传统住宅的元素，如坡屋顶、院墙、青瓦白墙，特别是在大的空间结构上，提倡封闭、半封闭的空间围合方式，以契合中国人内敛含蓄的心理特征，但在内部生活流线上几乎无一例外地吸收了欧式的生活方式，体现了现代都市人的生活理念和价值取向，项目配套都比较现代化，有公建、会所、游泳池等现代人所不可缺少的休闲和娱乐设施。

The number and distribution of the singular points of streamlines in the cross section of steady flow through a curved tube are discussed by using the method of topological structure analysis.

利用拓扑结构分析方法，分析了弯曲圆管内定常流在横截面上流线的奇点个数及分布规律，给出了二次流的漩涡数目由 2个变为 4个，流态结构发生分叉现象的理论判据·进而，利用Galerkin方法，得到了弯曲圆管内定常流的流函数和轴向速度的半解析表达式，给出了流态结构发生分叉现象的临界Dean数，所得结果与理论判则一

The modeling of products varied in different periods and evolved into diverse orientations. Slating board style paid more attention to the speed, while the half-slating board style of the head-shaking style also gradually turned to focus on the speed. Therefore, the style of speed is the evolutional direction of motorscooters in every period.

台湾速克达机车的产品及造形的发展就在这些与不同环境因素的互动下，机身由斜板式愈趋演变成流线型，而摇头式不管是复古车及一般型也渐强调流线的造形，所以，造型设计均往速度感的方向演化。
