查询词典 intersection theorems

One of two points of intersection of the Earth's axis and the celestial sphere.

地轴延线与天球相交的两点之一。

Its intersection with the celestial sphere will be a great circle-the ecliptic.

它与天球相交处形成一个大圆-黄道。

Traditional photogrammetry was based on forward intersection and resection using survey point, so collinear equation （object point, image point and center of projection lie in a line） was the kernel of the whole photogrammetry, and relative orientation and absolute orientation were based on ideology of coplanar corresponding image point.

传统摄影测量是基于测点的前方交会和后方交会，所以共线方程（即物点、像点与摄影中心位于一条直线上）是整个摄影测量的核心。

He is known for familiar results in elementary geometry; for example, the Euler line through the orthocentre (the intersection of the altitudes in a triangle), the circumcentre (the centre of the circumscribed circle of a triangle), and the barycentre (the "centre of gravity," or centroid) of a triangle.

他作了很大努力来发展一个较完整的月球运动理论，它由於包含了三体问题而特别困难；在1753年发表的部分解答曾帮助了不列颠海军部对月球表的计算。1772年，通过艰钜的心算完成了他的关於月球运动的第二种理论。

Based on Bezier curve continuance of first－order and second－order derivative, the characteristic vector equation of two Bezier curve is presented in point of intersection. The algorithm is not only of high accuracy with all of the interpolated points being on the curve theoretically, but also of very high speed in the real－time interpolation processes. The interpolation velocity does not change and the segment tolerance of interpolation can be control by selecting the parameter in cerement rationally every time.

为保证两段Bezier曲线在连接点处一阶导数、二阶导数连续，导出了两段Bezier曲线特征向量应满足的关系方程，Bezier插补法不仅在理论上可使所有的插补点落在曲线上，而且实时插曲补速度高，每次插补时可合理地选择参数增量，能使插补速度保证不变，也可控制弓高误差。

This paper introduces common background knowledge of intersection, mainly describes traffic control design principle ,such as signal timing and lane channelization.

本文介绍了交叉口的一般背景知识，重点阐述了平面信号交叉口的交通控制的设置原理，包括信号配时原理和路口渠化原理，概括了信号配时和路口渠化原理的本质相同点。

Finally, has carried on the contrast analysis after the original single road intersection signal control and the channelization plan, had proven this article proposes the method the validity and the feasibility.

最后，对原有的单个交叉口的信号控制与渠化后的方案进行了对比分析，证明了本文所提方法的有效性及可行性。

The primary step includes discharging mode design, signal design and channelization design of signalized intersection.

论文首先总结了目前信号交叉口交通组织优化的流程，然后根据流程对每一步骤的具体内容进行详细介绍。

If the geometry of the intersection may lead to these turn,the designer can use channelization devices and additional signing and pavement marking.Wrong-way movements are, in general, precluded by the use of cloverleaf designs.

如果几何的交汇点，可能导致这些反过来，设计师可以使用信道设备的和额外的签署和路面marking.wrong双向流动，一般来说，排除使用立交桥的设计。

This paper summarizes the channelization design of vehicle, non-motorized and pedestrian, and sets forth the improving composite of channelization and signal, further put forward the flowchart of channelization on signal intersection.

论文在信号交叉口混合交通特点的基础上，分别对机动车、非机动车、行人的渠化设计进行了总结，对渠化与信号的组合优化进行了阐述，并提出了信号交叉口渠化设计流程。

"The operators will suffer a temporary decrease in the number of consumers and short message services as people may not like having to provide their ID cards for a phone number," Xu Junqi, vice-dean with the Policy-Making Institute of the Telecommunications Research Centre under MII, said yesterday.

信息产业部下属的通信决策研究院副主任徐俊其昨天说：&实行手机实名制后，人们可能不太情愿用身份证注册手机号，所以通信运营商会暂时面临用户减少和短信用户减少的问题。&

I don't believe in make-believe!

我不相信这些虚构的故事。
