圆形

While Chrysocolla by itself is too soft for jewelry, when it appears as an inclusion in Quartz it is hard enough to polish as cabochons.

一方面硅孔雀石作为珠宝显得硬度不够，但另方面，当她以石英形式形成内含物时，她的硬度足够能将她打磨成一颗圆形宝石。

Individual plant can be amounted to high 35, 40cm, the bine is brawny, the flesh is qualitative, palm is Brown, old bine Chang Mu is changed character, there are the stipule of puce and cicatricle on the section; Xie Lu is lubricious, intimate circle, diameter 5, 8cm, the flesh is qualitative, luster, young leaf is a bit involute, gradually open and flat; Petiole shows aegis shape to wear be born at upside slanting in the center of blade, if form is raising small looking glass of one side face, on concentrated unripe bine, petiolar accident is differ, to all around extend, plump circle makes outward appearance of entire individual plant.

株高可达35—40cm，茎粗壮，肉质，棕褐色，老茎常木质化，节上有深褐色的托叶和叶痕；叶绿色，近圆形，直径5—8cm，肉质，有光泽，幼叶稍内卷，渐平展；叶柄呈盾状着生于叶片中心偏上部，形若举着一面面小镜，密集着生茎上，叶柄长短不一，向四面伸展，全株外观丰满圆整。

Sepals 5, broadly ovate or orbicular, ca. 0.5 mm wide, ciliate.

萼片5，宽卵形或圆形的，宽约0.5毫米，具缘毛的。

If you made a cross-section of a cilium and made a photograph of it with an electron microscope, you would see that the internal structure of the cilium is composed of a central pair of fibers surrounded by an additional 9 pairs of these same fibers arranged in a circle.

如果对纤毛做一个横切面，用电子显微镜拍摄，可以看到纤毛的内部结构有十对纤维，其中一对在中间，被另外九对相同的、成圆形排列的纤维包围着。

The gems we made are colorful and with more than 100 shapes, such as round, rectangle, square, marquise, oval, pear, triangle, yanbao, trapezia , cinquefoil, pentacle, ax, heart, leaf, arch bridge, rhombus, solid drip, sphere, moon, cabochons, beads, pendants, buttons.

本厂生产的宝石产品色彩丰富，形状更是五花八门，其中包括：圆形、长方形、正方形、马眼形、蛋形、梨形、三角形、元宝形、梯方形、梅花形、五角星形、心形、树叶形、拱桥形、菱形、立体水滴、球形、月亮形、素面、服装钮扣等100多种款式的产品。

And the circle detecting method also do well, it is worthy of popularizing and applying.

圆形检测的算法也取得了非常好的效果，有一定的推广和应用的价值。

Circle packing problem, one of the NP hard problems, is of great theoretical and practical value.

求解具有NP难度的圆形packing问题具有很高的理论与实用价值。

Experimental results demonstrate that the algorithm developed is fairly efficient for solving the rectangle and circle packing problem.

测试结果表明，本文算法对求解矩形和圆形装填问题是行之有效的。

The rectangle and circle packing problem is concerned with packing a subset of different size rectangles and circles into a rectangular container,with the objective of maximizing the container's area usage.

1前言本文所研究的矩形和圆形装填问题，就是将不同大小的矩形块和圆饼装入一个矩形容器中，以最大化容器的面积利用率为优化目标。

This paper describes a fast and efficient Fixed Heuristic Algorithm for unequal circle packing test problem with equilibrium constraint and all best known optimization solutions.

本文针对一类特殊的已知全部最优解的带平衡约束的圆形Packing考题求解，报告了一种基于不适合多边形(No-Fit-Polygon， NFP)的确定性启发式算法(Fixed Heuristic Algorithm，简称FHA)。

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。
