圆边

A new method for solving the coordinates of circular points in an image of an equilateral triangle and its inscribed circle was proposed.

提出了一种求解等边三角形及其内切圆的图像圆环点坐标新方法。

A circle of radius r is inscribed in an equilateral triangle ABC.

Then, under the consideration of mixed boundary value condition, a pair of dual integral equations for the rocking vibrations of a disk on saturated grounds are obtained, which can be reduced to a Fredholm integral equation of the second kind and solved by numerical procedures. Consequently, the dynamic compliance coefficient is evaluated and numerical results are presented to portray the influence of poroelastic effects on the dynamic interaction problem.

对于刚性圆板，作者首先采用Hankel变换对波动方程进行求解，得到了该控制方程在Hankel变换域内的通解，然后由混合边值条件建立了饱和地基上刚性基础摇摆振动的对偶积分方程，并将其化为第二类Fredholm积分方程，用数值方法计算了不同频率下基础的动力柔度系数，从而考察孔隙水的存在对基础摇摆振动特性的影响。

In this system,the VVVF(variable voltage variable frequency) control method based on magnetic flux trajectory is applied.In the system,it is the target for the magnetic flux linkage polygon to be greatly approximate to the ideal magnetic flux circle.Considering such limitations as the low speed torque ripple,high speed real time and the working frequency of switching element,through the subsection synchronization control method by applying different numbers of magnetic flux linkage polygon for different frequency range,the perfect precision specifications for speed can be obtained.

系统采用基于磁通轨迹法的他控式变频调速方案，以磁链多边形尽量逼近理想磁通圆为目标，并考虑低速转矩脉动、高速实时性和开关元件的工作频率限制等约束条件，通过采用分段同步控制方式，在不同的频段采用不同的磁链多边形边数，使系统获得了优异的转速精度指标。

Such as the Zhuang, Yao, Dong, Mulao, Maonan nationality has five colors, such as glutinous rice and glutinous rice Ciba, Dong, Miao, Mulao, Maonan, water, and other nationalities have pickled cabbage, sour meat, fish, such as acid, like to eat fish,"Pepper bone", Yao has a unique flavor of salt products - the "bird health," Maonan a tofu dish and a round of beef,"Dabian Lu", Dong, Yao, Miao, and other nationalities have to fight Camellia, Zhuang, Jing women like chewing betel nut, etc..

如壮、瑶、侗、仫佬、毛南等民族有五色糯米饭和糯米糍粑，侗、苗、仫佬、毛南、水等民族有酸菜、酸肉、酸鱼等，水族喜欢吃"辣椒骨"，瑶族有风味独特的腌制品——"鸟酢"，毛南族有豆腐圆和菜牛肉"打边炉"，侗、瑶、苗等民族有打油茶，壮族、京族妇女喜欢嚼槟榔等等。

Do you mean to round off the edges of the table?

你的意思是不是要把桌子的边棱角）磨圆吗？

You can see,the edge is rounded and the car speed is low.

你看，车边是圆的，而且车速也不快。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
