The circle detection method based on Hough Transform has been used more and more widely in recent year since it possesses the high reliability and the strong anti-noise ability.

圆检测方法基于Hough变换已使用了更多的和更广泛地在最近一年以来，它具有高可靠性和强大的抗噪能力。

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。

I used circular polarization helix antenna and linear polarization horn antenna do a lot of experiments for many situation, for example, different polarization mode、different distance between antennas and metallic body among antennas, and I acquire some valuable data.

使用圆极化方式的螺旋天线和线极化方式的喇叭天线分别对不同极化方式、不同天线间距和天线之间存在金属障碍物等各种情况进行了大量的实验，并获得了有价值的数据。

By analytic geometry method and solving quadratic equation,a computer simulation algorithm of digital projection under arbitrary scanning locus was proposed.The algorithm is based on the rules of attenuation of monochromatic X-rays.Through mathematical modeling and computer simulation,digital projections of ellipsoid and cylinder in circular and helix scanning modes are exemplified respectively,which are proved to be correct by FDK and PI-line reconstruction algorithms.

介绍了一种利用解析几何和求解二次方程仿真任意扫描轨迹下的锥束射线投影数据算法，该方法基于单色射线贯穿物体的衰减理论，通过数学建模与计算机仿真，给出了椭球、圆柱两种典型模型分别在单圆、螺旋线扫描轨迹下的投影数据仿真结果，并利用FDK和PI线重建算法进行验证，证明了该种数值仿真方法的正确性。

Support for the notion that these works may be autobiographical comes from the fact that the figure, with its large dome-shaped, close-cropped head, bears a striking resemblance to Zhu Wei himself.

之所以有观点认为这些作品带有自传性，皆因这些作品中人物那硕大的圆脑袋和剪得极短的发型，都和朱伟本人惊人的相似。
