The EM field of arbitrary point in an irregular loop can be considered as the sum of the EM field of many circle loops in the irregular loop at the point. Therefore the authors may obtain the EM field of the irregular loop as long as the authors work out the EM field of each of the circle loops.

不规则回线内任一点的电磁场可以看成是其内部多个圆形回线在该点的电磁场之和，因此，只要求出不规则回线内各个圆形回线在该点的电磁场，将它们叠加就可得出不规则回线在该点的电磁场。

In a circle,when an isogon unlimited number of margin increase, the limits of its perimeter is circumference, and its size limited is the area of the circle.

（《九章算术》方田章圆田术刘徽注）这就是说，圆内接正多边形的边数无限增加的时候，它的周长的极限是圆周长，它的面积的极限是圆面积。

When Iktomi finished speaking, he gave the Lakota elder the web and said..."See, the web is a perfect circle but there is a hole in the center of the circle."

当Itkomi停止说话的时候，它将网交给了老人并说道："看，这网就是一个完美的圈除了中间有一个小洞。"

In order to control the flow separation by reducing the diffusion factor and enlarging the diameter of inner circle, the meridian plane profile of the return channel was redesigned, which is achieved by substituting arbitrary curve for the circle with no change of the axial length of the stage. Bezier curve with eight parameters was chose to describe the shape of meridian plane profile, and the optimization of the meridian plane profile was implemented combining back-propagation neural network with genetic algorithm.

改进的主要思路是减小弯道前半部分通道的扩压度，并同时加大弯道出口内侧的转弯半径，主要做法是在不增加整级轴向尺寸的前提下，用任意曲线取代传统弯道的同心圆环结构，给定弯道回流器子午型线的外侧型线，采用Bezier曲线对内侧型线的2段曲线进行参数化描述，利用遗传算法和反向传播(back-propagation，BP)神经网络相结合的方法对内侧型线进行优化，得到新的弯道回流器子午型线。

The results showed that there were two kinds of grains in the cells,one was large and had low electron density,Gl for short,while the other was small and had high electron density,Gh for short.The latter ones had a circle around it which can be seen through the microscope.During the aroma releasing period,the shape of the two grains changed distinctly,which led to the inference that Gl was the leucoplast,the store-room of aroma precursors or energe substances,and that the Gh was probably the lysosome which is related to the enzyme system?s aroma producing.The circle around Gh is the formed fragrant constituents and the aroma forming is the result of the interaction of Gh and Gl .

结果发现，茉莉花瓣细胞中存在电子密度较低、体积较大的颗粒和电子密度较高、体积较小的颗粒（分别简称为Gl和Gh颗粒），并在Gh颗粒周围存在清晰的晕圈；在茉莉花释香过程中，两种颗粒在形态上均发生明显的变化，推测Gl颗粒可能是白色体，是茉莉花香气前体物或能量物质的贮存器，Gh颗粒可能为溶酶体，与香气形成的酶系统有关，Gh颗粒周围存在的晕圈可能是香气物质，香气物质的形成是Gl和Gh颗粒相互作用的结果。
