查询词典 coronagraph

In this sharp composite from the Hubble Space Telescope, Fomalhaut's surrounding ring of dusty debris is imaged in detail, with overwhelming glare from the star masked by an occulting disk in the camera's coronagraph.

在这幅来自哈勃空间望远镜的精细合成图像中，北落师门周围的尘埃环的碎片能够精细展现，并且在相机的日冕观测仪下，能够观测到被一神秘圆盘遮蔽的恒星发出十分耀眼的光线。

A coronagraph uses an occulting disk to create an artificial eclipse, revealing the corona and objects hidden in the solar glare. C2's field of view extends from about 2 to 6 solar radii, while C3's runs from about 4 to 32 solar radii.

日冕仪利用一个遮光板产生人造日食，使得淹没在太阳强光中的日冕和其他天体显现出来）。C2照相机的视野范围在2到6个太阳半径之间，C3的视野在4到32太阳半径间。

The coronagraph has been used to block the light from the brightstar allowing the search for the dim glow of the planet HR 8799b.

通过星冕仪技术，明亮的恒星光全部被遮蔽，以便我们寻找行星HR 8799b的微弱光芒。

Arcing toward a fiery fate, this Sungrazer comet was recorded by the SOHO spacecraft's Large Angle Spectrometric COronagraph on 1996 Dec.

以优美的弧线走向了惨烈的毁灭之路，这颗掠日彗星由SOHO探测飞船的广角光谱日冕观测仪于1996年12月23日记录得到。

The coronagraph has been used to block the light from the brightstar allowing the search for the dim glow of the planetHR 8799b.

通过星冕仪技术，明亮的恒星光全部被遮蔽，以便我们寻找行星HR 8799b的微弱光芒（PS：我们在Photoshop中可以做类似操作，把中央区域给全部dell后，整个图片的亮度、对比度等都会有巨大改变，继续做大幅度增加亮度、对比度操作，有近似的效果——译注）。

LASCO, the Large Angle and Spectrometric Coronagraph, sometimes known as the SOHO C3 or red image, is one of the wave lengths captured.

LASCO，即"广角度广频谱日冕观测仪"，有时候也叫"SOHO C3"或者"红色影像仪"就是使用其中某一波长。

Astronomers have partially solved the problem of looking at objects near to a star's bright glare by inventing the coronagraph, which focuses all the incoming light around a dark spot in the telescope's innards, neatly clipping off most of the central starlight and passing on much of the planetary glow.

天文学家用日冕仪一定程度上解决了观测恒星强光附近物体的难题。日冕仪精巧地阻挡了进入望远镜中央区域的绝大部分恒星光，让更多的行星光进入望远镜。这样一来，日冕仪就能专注于分析望远镜内部圆形黑暗区域周围的入射光。

The composite image and movie show the action in both extreme UV wavelength near and just above the solar surface overlaid on the frames from STEREO COR1 coronagraph that shows the material as it rises out into the corona.

视频是由图片跟影像叠加复合而成，从中可以看到太阳表面以及被日冕观测仪镜框部分叠加覆盖的太阳外部的强烈紫外线（简称UV，图中太阳桔红色部分）活动，从日冕观测仪里看到的影像显示日珥上升并冲出日冕层。

In this sharp composite from the Hubble Space Telescope, Fomalhaut's surrounding ring of dusty debris is imaged in detail, with overwhelming glare from the star masked by an occulting disk in the camera's coronagraph.

在这张哈勃空间望远镜拍摄的清晰合成照片中，北落师门周围的尘埃碎片组成的光环清晰可见，来自恒星的耀光被相机的日冕仪遮掩园面给遮盖了。

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。
