The effects of the aspect ratios of the ellipsoidal cavity on the relative strengths of these dipoles and on the radiation patterns are discussed in detail.

文中详细分析了椭球腔的形状因子对地震矩张量元素和远场地震波辐射图案的影响。

Based on the method of Dyadic Green s functions,the radiation patterns of the microstrip antennas printed on the surface of elliptic cylinder are analysised and calculated in this paper.

文中采用并矢格林函数方法，分析和计算了椭圆柱面上微带天线的辐射特性，并讨论了辐射特性随离心率的变化规律。

In this paper,the radiation from a monopole on an elliptic cylinder is discussed by UTD for convex surfaces and two examples are given whose results are consistent with experimental data,which proves UTD to be available.

文中以单极天线为例应用UTD的曲面绕射理论对椭圆柱上天线的辐射特性进行了研究，给出了两个相关算例，结果与实际基本吻合。

The direction of maximal radiation of the main beam must be directed into the geometrical center of the elliptic surface of the offset parabola.

主波束最大辐射方向必须瞄准偏馈抛物面椭圆表面的几何中心。

Feed positioning in the way that its phase center exactly coincides with the focus of the offset parabola and its direction so that the radiation maximum falls in the geometric center of the elliptic reflector surface are not intuitive at all, as in classic parabolic antennas.

馈源用这样的方式定位——其相位中心准确位于偏馈抛物线反射器的焦点，方向也要准确，这样辐射最大值才能落在椭圆形反射面的几何中心，这样一点也不直观，正如标准的抛物面天线。

Mathieu functions are frequently encountered in many radiation,scattering and guided wave problems, which are formulated in the elliptic cylindrical coordinate system.

本文给出了计算马丢函数和变型马丢函数及其导数值的程序流图和相应的有用数学公式，并讨论了算法。

Because of the ellipticity of the earth's orbit the solar radiation incident on the earth is about 7% greater in December than in June.

因为地球轨道是椭圆，入射到地球上的太阳辐射在12月份约比6月份多7％。

The feed radiation angle, both in horizontal and in vertical plane has to be the same, regardless the ellipticity of offset parabola.

馈源的方向角在水平和垂直都应当相同。而不管偏馈抛物面的椭圆率如何。

Lyman-alpha blobs are so called because they strongly emit radiation due to the Lyman-alpha emission line of hydrogen gas.

Lyman-α云球名字的缘由是因为在氢气的Lyman-α谱线有强发射。

But the energy was concentrated in a spectacularly sharp line in the emission spectrum--in other words, the radiation was exceedingly uniform, consisting of a single wavelength with little contamination from other wavelengths.

但是能量被集中在发射谱中一条非常狭窄的谱线上。也就是说，辐射是极度均匀的，只包含有一个单一的频率，而没有其他频率的干扰。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
