The new antenna has the advantages of sim ple structure, easy feeding and a wide frequency range, and circular polarized wave. The characteristics are m uch better than a bifilarbackfire helicalantenna, a shortbackfire antenna and a backfire...

它具有结构简单、馈电方便、遮挡小、频带宽、增益高且易于产生圆极化波等优点，性能远优于带相同接地板的螺旋天线、普通短背射天线以及单线背射螺旋作馈源的短背射天线。

One sector in the outer circularity of iris is used to represent the region of eyelash occlusions .

该算法基于canny算子检测图像中的眼睫毛；利用虹膜的外圆，提出了用一个扇形区域来表示眼睫毛遮挡区域。

Excluding the pupil and the sector, the rest of the outer circularity is the effective region of iris.

除去眼睫毛遮挡区域与瞳孔，虹膜外圆余下的部分即为虹膜的有效区域。

Geometric simplification is thus hard to apply when the visual appearance of an object depends on resolving the ordering and mutual occlusion of even very close-by surfaces, potentially with different shading properties.

几何简化因此是难以用于当一个对象的视觉效果取决于解决的顺序与十分靠近表面的相互遮挡，以及不同的着色属性的简化。

At the far right, the Moon is nearly hidden by an approaching cloudbank, but the clouds themselves actually cast shadows in the bright moonlight, creating the effect of Moon rays across the evening sky.

全景图的最右边，月球几乎完全被行进的云堤遮挡，但实际上，正是这些云层本身在明亮的月光下投下了阴影，营造了穿越傍晚天空的月球射线效果。
