圆的

Using the relations between harmonic conjugation elements,we can determine the relations between polar point and polar line more widely.

度量几何中圆的切割线之间所确定的数量关系，推广到射影几何里一般二次曲线中，利用调和共轭元素之间的关系，更广泛地确定了极与极线的相互关系，着重介绍了二次曲线的度量性质与射影性质的内在联系。

The results are much better than the other approaches'. Then we give another method for approximating offset curves. The circle is first approximated by regular polygon within some tolerance. The exact offset curve is then approximated by the convolution of the regular polygon with a B-spline curve or a NURBS curve having the same degree.

与此同时作者从基圆的正多边形逼近出发，通过求解包络的技巧给出了等距曲线逼近的另一个算法，可整体估计误差，所得的等距逼近曲线为与基曲线同次数的B样条或NURBS曲线，克服了国际上现有同类算法中逼近曲线次数几倍于基曲线次数的缺陷。

Left side and right side two revolve the triangle frame, puts on circle tube middle outside.

左边和右边的二个旋转的三角的架，放在圆的管的中间的外边。

Foot of the statue of Dr. Sun Yat-sen is the steeple bell, semilunar Place bell roof arcs, top of the tomb and the tomb of the hemispherical dome roof, as the first round bell pendulum slip. Place the tripod southern Taiwan (now the images of Dr. Sun Yat-sen) to the clock bell in New York, the "ting" is the ancient symbol of power. The clock is therefore with the whole "to arouse the people to build in" with the United States.

山下中山先生铜像是钟的尖顶，半月形广场是钟顶圆弧，而陵墓顶端墓室的半球形的穹隆顶，就像一颗溜圆的钟摆锤，广场南端的鼎台为大钟的钟纽，"鼎"在古代是权力的象征，因此整个大钟乃含"唤起民众，以建民国"之意。

Establishing 6 fuzzy sets such as cells with increscent karyon, cells with deeply dyed karyon, cells whose area rates of the karyon and cytoplasm are excessive and so on and 6 membership functions.The paper partitions the sample space furtherly into 4 nomarl pattern, and realizes the recognition of the cancer cells in pleural fluid.

建立了诸如细胞核增大的细胞、细胞核深染的细胞、细胞核不圆的细胞等6个模糊集合和与之相应的6个隶属函数，并根据模糊集合的运算法则将胸水细胞样本空间进一步划分为4个标准模式，实现了胸水癌细胞的识别。

The Bith species of humanoid are characterized by their large craniums, huge round, lidless eyes, and tiny mouths under their fleshy face folds.

人形种族比思人的特征是他们巨大的颅骨，大而圆的无眼睑的眼睛，和他们多肉的面部褶皱下的小嘴。

The time it took the sphere to swing from end to end was determined by an arcane conspiracy between the most timeless of measures the singularity of the point of suspension , the duality of the plane s dimensions , the triadic beginning of

球从一端摆到另一端的时间，取决于最永恒的测量的神秘合谋；暂停点的单一性，摆动平面的二重性，π的三合一起点，根的秘密二次性质，以及圆的无尽完美。

The time it took the sphere to swing from end to end was determined by an arcane conspiracy between the most timeless of measures; the singularity of the point of suspension, the duality of the plane's dimensions, the triadic beginning of π, the secret quadratic nature of the root, and the unnumbered perfection of the circle itself.

球从一端摆到另一端的时间，取决于最永恒的测量的神秘合谋；暂停点的单一性，摆动平面的二重性，π的三合一起点，根的秘密二次性质，以及圆的无尽完美。

There were many signals suggesting that the Fed has been mismanaging the dollar, which, with the mismanagement of the yen and the uncertainty of the unique euro (the first paper currency not anchored in either gold or backed by a government), became the sole reserve currency in the late 1990s.

有诸多迹象显示Fed管理美元的方法是错误的。由于日圆的管理不当以及欧元这种独特方式的不确定性（欧元是第一种既没有黄金也没有某个政府支撑的纸币），所以美元成了上世纪90年代后期唯一的储备货币。

The naginata's length and weight made it an efficient weapon against the sword, and its circular execution made it one of the most graceful and fluid of classical Japanese combat systems.

薙刀的长度和重量对权力使它为一种有效率的武器，并且它的圆的实行做它古典日语的最优雅和流动的之一与系统作斗争。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
