查询词典 geometries

The different width and length of Hilbert curve geometries were investigated by finite element method. The computation results show that the DGS rejects the signal at two frequencies 2.43 GHz and 7.11 GHz from 0~9 GHz with more than -15 dB suppression. Q factors of the Hilbert curve DGS is bigger than that of conventional DGS.

通过有限元法对不同Hilbert曲线宽度和长度的DGS结构微带线进行计算，计算结果表明，该结构在0~9 GHz频段内表现出2.43 GHz和7.11 GHz这2个谐振频率，对应频率的通带反射损耗低于-15 dB，并且阻带特性在谐振频率处比传统DGS微带线有更高的 Q 值。

Then the influence of the different Coanda surface shapes including the circle, elliptical and logarithmic spiral TE geometries on the performance of the circulation control airfoil were investigated.

在此基础上研究了具有圆、椭圆和对数螺线形式柯恩达表面的环量控制翼型性能的变化，初步探讨了射流层附壁与高曲率表面特征参数的关联。

Relationships between the minor axis semidiameter and major axis semidiameter have been empirically determined for different structural detail geometries.

对于不同结构细节的几何形状，已经确定了短轴和长轴半径之间的关系。

Fractal geometries of Hilbert and H curves can be implemented to miniaturize the antenna, too.

研究表明Hilbert和H分形天线具有降低天线结构尺寸的优点，相对于一般阵子天线，结构尺寸大为降低。

He did not grant independent existence to the non-Euclidean geometries.

他不承认非欧几里德几何的独立存在性。

In the 19th and 20th centuries mathematicians began to examine non-Euclidean geometries , in which space can be said to be curved , rather than flat .

在19世纪和20世纪的数学家开始审查非欧几里德几何，在这种空间可以说是弯曲的，而不是持平。

Many took the existence of consistent non-Euclidean geometries to be a direct refutation of both Mill's and Kant's philosophies of mathematics.

不少人都采取了一贯存在非欧几里德几何是直接反驳都穆勒和数学康德的哲学。

It is said that this vast network is overlaid in the form of "sacred geometries."

据说这个广阔的网络是很多的"神圣的几何图案"。

The new schemes hold the main advantages of the DG finite element method: the method can easily handle complicated geometries and the boundary conditions; the method is highly parallelizable.

格式保持了DG有限元方法的优点：易处理复杂的几何区域和边界条件，具有高度的并行性。

Using hybrid CSG/Brep representation, the whole solid model is a CSG tree made of leaf nodes with basic Brep, which include triangular mesh, subdivision surface control mesh and basic geometries with parametric representation.

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。
