Through transformation of parameters, the meshing design system among Hy-Vo silent chain, sprocket and hob was built up based on the research of the pitch increment and the equivalent apothem increment of the effects on the common normal line length when the Hy-Vo silent chain was wrapped around and located on the sprocket, with the proper meshing conditions of Hy-Vo silent chain and sprocket into consideration. The design method of common normal line length was put forward that can be used when the value of the sprocket pressure angle was equal or unequal to the value of the Hy-Vo chain plate pressure angle.

在分析Hy-Vo齿形链链节围在链轮轮齿上定位时其节距增量和当量边心距增量对链轮公法线长度影响的基础上，根据Hy-Vo齿形链与链轮的正确啮合条件，通过参数变化，建立了Hy-Vo齿形链－链轮－滚刀三者之间的啮合设计体系，提出了既适用于链板齿形角等于链轮压力角情况，也适用于链板齿形角不等于链轮压力角情况的Hy-Vo齿形链链轮公法线长度的计算方法。

Mathematics the shortest line between two points on a mathematically defined surface (as a straight line on a plane or a an arc of a great circle on a sphere).

在数学定义上的表面上两点之间的最短的线（如平面上的一个直线或球体上大圆的一个弧线）。

A traffic network includes a node set and an arc set,which can be derived by the line. Before the line is converted to network, data processing must be done.

交通网络可抽象为节点集和弧段集的集合，其图形基础是线，再通过线派生出网络相应的节点集和弧段集。

Applying theories of numerical analysis and higher geometry, the corresponding mathematical model of stem line is established according to different stems. Whereby, the centers, radii of the arc and its tangent points with the water-line can be found and the curve of arc radius is thus determined. A general formula for expressing stem curved surface is introduced.

A formula was deuced, which shows the relation between the outlet angle of center line of channel and wrap angle, variant coefficient, if variant Archimedes spiral is assumed the curve of center line of plate plane. It is the basis for controlling outlet angle of channel.

推导了采用变异的阿基米德螺线作为平面流道中线时，中线出口角与包角和变异系数之间的关系式，为设计中控制流道出口角提供了依据。

For example, if the object is a simple line, the Area choice will be unavailable because a line does not have an area to fill.

例如，如果对象是一个简单的线条，平面选项将是不可用的，因为线条没有一个填充区域。

But, most of the traditional mushroom structures are restricted to only single EBG frequency design. In this thesis, we propose a novel concept about the interlaced periodic arrayal of the mushroom structure with the suspending microstrip line. By the simulation and measurement result, it is verified that the mushroom structure with the suspending microstrip line can reveal multi-band EBG characteristic.

而传统的蕈状结构的应用，多半只有操作在单一频率的电磁带隙特性，而本论文就针对了蕈状结构结合悬置微带线架构的电磁带隙特性研究，并提出了一种新的穿插周期排列的概念，透过电路模拟与实作量测的验证，我们成功的让蕈状结构结合悬置微带线的架构展现出多频电磁带隙的特性，并且，我们利用了这一个新概念设计了一种新型的微波电路。
