两侧对称的

The diffraction theory of Kirchhoff is applied to the four-pinhole aperture diffraction screens, the intensity, the zero-contour of the real and imaginary parts of complex amplitude and the phase distribution in deep Fresnel diffraction region are simulated, and it is found that the bright spots in interference field show central symmetry distribution. When the observation plane close to the diffraction screen, the zero-value points of light intensity can form line segment, on which the eccentricities of the light intensity isoline are close or equal to 1, the intensity changes very fast on both sides of the zero-line of light intensity.

利用基尔霍夫衍射理论计算了四圆孔径衍射屏在菲涅尔深区形成的的干涉光场的强度、零值线和相位的分布，发现干涉光场亮斑关于中心呈对称分布，在距离衍射屏较近的观察面上，光强值为的零点组成光强零值线段，该线段上光强等值线的离心率都接近或等于1，其两侧的光强值变化非常剧烈。

When the sun in the middle, the two planets in the sun with a symmetric planar sides of the Earth at this time just running the middle of this, will be the impact of solar magnetic storms, with a magnetic storm the size of the quality of the planet.

当太阳在中间，两个行星分别在太阳的对称同一个平面两侧，如果此时地球刚好运行到这中间，就会受到太阳磁暴的影响，产生磁暴的大小与行星的质量有关。

Result shows that the baffle of burner has very little influence on the total resistance characteristic; both the speed of rich side and lean side are affected by the angle of burner as a whole, furthermore, the lean side is influenced more greatly; the separation performance could be enhanced with the increase of burner's angle and the best separation effect could be acquired when the three baffles are dissymmetrically arranged.

结果表明，燃烧器挡板角度的调整对燃烧器的总体阻力特性影响很小；燃烧器挡板偏转对于燃烧器整体以及浓淡两侧的气流速度都有一定的影响，且对淡侧影响较大；燃烧器的浓淡分离效果随挡板偏角的增加而显著增加，且三挡板非对称布置的浓淡分离效果最好。

This is a properly positioned, nonrotated film as evidenced by (1) comparative anterior ribs equidistant from the pedicles,(2) medial aspects of the clavicles symmetrically positioned,(3) the carina approximates the right pedicles, and (4) no difference in aeration between the two sides.

一张适当位置，非旋转的胸片是通过以下几个方面判断的：（1）从椎骨上比较各前肋之间间距相等，（2）锁骨的内侧面呈对称分布，（3）气管隆凸靠近右侧胸椎，还有（4）两侧的充气影应该是相同的。

Shinto before, on both sides of planting cypress Parker, to create an atmosphere of solemn silence, the culture Ye temple to respect the sentiments; runs through the temple's main axis in an online, left a symmetrical, layout stringent.

前为神道，两侧栽植桧柏，创造出庄严肃穆的气氛，培养谒庙者崇敬的情绪；庙的主体贯串在一条中轴线上，左有对称，布局严谨。

A: There are no planetary alignments in the next few decades, Earth will not cross the galactic plane in 2012, and even if these alignments were to occur, their effects on the Earth would be negligible.

答：在今后的几十年当中，不会出现行星排成一条线的情况。2012年，地球也不会跨过银道面（译者注：银道面就是银河系的主平面。银河系成员如恒星、尘埃云及气体等，绝大部分都对称地分布在这个平面的两侧。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
