corona ring

lobes broadly triangular, ca. 0. 5 mm. corona ring like, rim 5-toothed.

约，裂片宽三角形毫米副花冠，凸缘5切成齿形。

Clearly drawn is not only a total solar eclipse, but the solar corona and the diamond ring effect visible when sunlight flows only between mountains on the Moon.

很明显画中并不仅仅是日全食，其中还能看到日冕以及当日光刚从月球山峰之间露出时出现的钻石环效应。

The author calculates distribution of electric field and potential under three cases: both the high voltage and grounding end with and without corona ring, and only the high voltage end with corona ring.

计算了在清洁合成绝缘子高压端、接地端两端安装均压环、未安装均压环以及只在高压端安装均压环的电场和电位分布；
