查询词典 Baily's beads

Baily's Beads The moon has valleys and when the sun is behind these the light is not blocked.

贝雷的珠-月亮有山谷，当太阳后面这些鉴于没有阻挡。

Although, the number and brightness of Baily's beads used to be unpredictable, today the Moon is so well mapped that general features regarding Baily's beads are expected.

在过去，人们无法预测贝利珠的数量与亮度，但是如今，由于对月亮表面已经相当了解，已有可能粗略预测贝利珠的大致特征。

Pictured above, a series of images recorded Baily's beads at times surrounding the recent total solar eclipse visible from Novosibirsk, Russia. The complete series can be seen by scrolling right.

上图所显示的倍里珠变化系列照片是最近在俄罗斯的新西伯利亚观测日全食时拍摄的。

Observers in the path of totality at a solar eclipse see first a gradual covering of the Sun by the lunar silhouette for over an hour, and then a set of 'Baily's beads', the last bits of the bright photosphere shining through valleys aligned at the edge of the Moon.

在一次全食观测中，观测者看见太阳逐渐地被覆盖，最后显示出黑色轮廓的影子，时长超过一小时，之后形似一组珠子状，最后一点明亮的光球层闪烁着排列在月球轮廓的边缘。

As the Baily's beads disappear behind the advancing lunar edge (the phenomena occur in reverse at the end of totality), a thin reddish edge, called the chromosphere (named from the Greek chromos, colour), appears.

随着日蚀的进程，珠子状的物质消失了（这种现象于在全食开始时相比是相反的发生）。一个薄的为微红色的边缘，被称为色球

Baily's beads 倍里珠 An effect occurring just before second contact or just after third contact of a total solar eclipse, when the Moon's irregular surface makes sunlight appear as beads at certain parts of the disk.

日全食中第二次接触前或第三次接触后发生的现象。当月球凹凸不平的表面几乎完全覆盖太阳时，部份太阳光会被月球凸出的地方分割开，看起来就像一颗颗圆珠般，是为倍里珠。

Diamond ring effect 钻石环效应 Occurs during a total solar eclipse when only one baily's bead remains, or in practice, when a patch of sunlight can be seen at one side of the disk, resembling a diamond ring (this usually happens before baily's beads appear before totality or after baily's beads are formed after the end of totality).

通常於日全食前倍里珠出现末段和日全食后倍里珠出现前段发生。当只有一粒倍里珠在太阳圆盘时(实务上为光束只在太阳一面可见时)，该圆盘看上去就像环里突出一粒钻石般，因而得名。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
