查询词典 projections

Whereas parallel projections are used to project points onto the image plane along parallel lines, the perspective projection projects points onto the image plane along lines that emanate from a single point, called the center of projection.

与平行投影沿着平行线将物体投影到图像平面上不同，透视投影按照从投影中心这一点发出的直线将物体投影到图像平面。

The name of this café easily reminds people of an invention originated by French people contributing to the modernity of this world. More than one hundred years ago, on December 8th, 1895, Lumière Brothers' Cinematograph projections of 50-seconds scenes were first on display at the Grand Café in Paris, which was believed to be the first movie in the world.

咖啡厅的名字让人想起一项法国人的发明，这项发明对推动世界现代化进程功不可没。1895年12月8日，在巴黎的格兰迪咖啡馆，吕米埃尔兄弟首次用他们的电影放映机放映了50秒长的画面，这被看作是世界上第一部电影。

First, a special normal transversal at the initial point is constructed and a second-order Taylor's algorithm is used to trace the projections along the aforementioned normal transversal. A curvature based method for controlling iteration step is further proposed by projecting the given point onto the curvature circle of the normal transversal at the initial point. Finally gradient based method for correcting iteration errors is put forward.

首先构造初始点处的一条特殊的法截线，并给出沿着该法截线追踪投影点的二阶泰勒迭代方法；然后将给定点向初始点处的法截线的曲率圆作投影，提出基于曲率的步长控制策略，在此基础上给出了基于梯度的迭代误差矫正方法。

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。

If the projections are accurate, and the weak dollar boosted international commodity prices on the one hand, China's imports increased costs; On the other hand, makes the economic benefits of the sale of raw material deterioration, more willing to expand production, increase the supply of global tensions.

如果上述预测准确，弱势美元一方面提升了国际商品价格，增加了中国的进口成本；另一方面使得原材料出售者经济收益恶化，更加不愿意扩大产量，加剧全球范围供应紧张状况。

In this paper, the requirement analysis, design and implementation of the system are introduced in detail.

此论文详细介绍了系统的需求分析，系统设计和具体实现。
