查询词典 sphere

An initial spherical parameterization is firstly constructed by lifting planar parameterization to the sphere through the stereographic projection. Then we introduce an efficient approach based on bary centric coordinate to improve the initial spherical parameterization. At last, a uniform spherical parameterization is generated by a Moebius transformation.

通过立体投影将现有的平面参数化方法推广到球面上，得到一个初始的球面参数化；为了减小变形，引入质心坐标进行全局优化；最后用Moebius变换均匀化最终的球面网格。

Holographic concave gratings with three stigmatic points can be implemented through considerable design. Results obtained from holographic gratings can also be applied to ruled gratings. Sphere and coma aberrations for a planar concave grating are achieved through power expansions.

通过适当的设计，可以使得全息光栅具有三个无像差点，这些分析虽然是针对全息光栅而得到的，但通过记录参数的合理选择可以将其应用到刻划光栅中去，得到等价的刻划光栅的参数。

We do not think creation content is our special skill, so we can put more energy in creation technology, use information of this technology conformity next, no matter integrated information is to make your email better search, still make search result more accurate, discuss inside integrated perhaps community, the information on forum, these missions that we think is us are in, we are met a time is dedicated the place that in these we think we can have been done, is not like an octopus, let oneself stretch the sphere that differs to each.

我们并不认为创造内容是我们的专长，所以我们会把更多精力放在创造技术，然后用这个技术整合信息，无论整合的信息是让你的电子邮件更好搜索，还是让搜索结果更精确，或者是整合社区里面讨论的、论坛上的信息，这些我们认为都是我们的使命所在，我们会把时间专注在这些我们认为我们能够做好的地方，而不是像一个章鱼一样，让自己伸到每一个不同的领域去。

The LP approximation by strong summability of Fourier-Laplace series of a function defined on unit sphere is discussed.

本文讨论了球面函数的Fourier—Laplace级数的强求和在LP尺度下的逼近问题，其结果是球面上强求和的某些已有结果的补充，也可以看成一元或多元Fourier级数相应结果的球面类比。

In this paper we investigate the researching state, the developing situation and the prospect for the summability , the strong summability and their relevant approximating oder , strong approximating oder of Cesdro mean - an important linear summation process of the Fourier - Laplace series of functions on sphere.

本文研究了球面上的函数用其Fourier—Laplace级数的一种重要的线性求和法-Cesaro平均来求和与强求和及其相应的逼近与强逼近的阶的研究状况、发展态势和前景展望等。

Computation result is compared with the direct summation of the series form solutions of the electromagnetic filed over the sphere.

同球外电磁场直接级数求和表达式的计算结果进行了比较。

Finally, we give some examples for representing surface of revolution and sphere as rational B-spline patches.

文中附有旋转曲面和球面的生成实例。

The hemispherical spectral reflectivity of the surface of a strip tangent to an integrating sphere is determined by a high-speed lock-in technique. At the same time, the radiance temperature of the strip is measured by the multi-wavelength high-speed pyrometer from approximately 1000 K to the melting point.

带状试样被亚秒级的脉冲大电流通电加热到溶点，其表面的光谱半球反射比利用高速的数字锁相技术可方便地获得，同时一台多波长高速高温计可测量被测试样从1000K到溶点的光谱温度。

Visited by a mystic illumination in 1745, Swedenborg claimed a direct vision of a spiritual world underlying the natural sphere.

参观了由一个神秘的照明在1745年，威登柏格要求直接视野的精神世界背后的自然领域。

He says the officials who wield such power over the artistic sphere are not considered important in the bureaucracy and so tend to be conservative and sycophantic.

他表示，那些在艺术领域拥有很大权力的官员，通常在官僚机构中未得到重用，因此他们往往比较保守，而且阿谀奉承。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
