Since it is much dimmer than the photosphere , it was only visible during a total solar eclipse before the invention of coronagraph .
由於日冕比光球暗,在日冕仪发明前人们只能在日全食期间看到日冕。

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。

Coping with the vast difference in brightness between planet and star requires a coronagraph in the telescope to physically block out the star or "virtual coronagraph" software to remove starlight from the image.
处理行星与恒星亮度的巨大差别要求在望远镜里装上日冕观测仪以把恒星遮住,或是用"虚拟日冕仪"软件把星光从影像上除掉。

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。

Eventually, propinquity of spacecraft to the Sun plus improvements of space solar telescopes in spatial, temporal and frequency domains may allow such space solar telescopes to take over completely, perhaps adding to observations of distant stellar coronas to explain the coronal-heating problem.
最终,太阳观测卫星直接抵近观测并且会有先进的空间望远镜加入这个队伍,以后空间太阳望远镜将完全承担任务,然而对远距离星体日冕的观测同样也能解释日冕加热的问题。

On the other hand, through the discussion on coronal density of flares, we found that the column mass density at the top of chromospheric flare model can not be represented the total mass above the chromosphere and the coronal density can be estimated from presure balance based on semiempirical model. Through estimations, the results show that the total mass above the chromosphere is about the same as the mass between the top of chromosphere and electron source, which so give an evidence that the source of electrons is situated at the top of flare loop.
另一方面,通过对日冕物质密度的讨论发现,半经验模型中色球顶部柱数密度不能用来代表耀斑环在日冕内的总物质,日冕物质密度可用日冕气压与半经验模型中色球顶部压力近似相等来进行估计,进而发现耀斑环在日冕内的总物质与前面估计的色球顶部到非热电子源之间的总物质近似相等,结果趋向于支持非热电子源位于环的顶部。

The main characteristics include: the quiet Sun corona has a rapid response to the flare heating, within 2 second the corona temperature increases nearly one order of magnitude, but later such increase becomes very slowly; the downward velocity at early stage of impulsive phase is too small to be negnected; chromospheric evaporation made by conduction shows some intensely, the maximum evaporated velocity may be as large as 1000 km/s; the chromospheric condensation appears just when the chromospheric evaporation takes place and its place always coincide with that of transition region in the early stage; the maximum of chromospheric condensation occurs also in the early stage of impulsive phase, at which the density in condensation may be larger two order of magnitude than that of surround and the downward velocity may be as large as 100 km/s; after the maximum of chromospheric condensation, its strongth decreases gradually but its width becomes greater with time and have a tendency to transport into deep chromosphere; the front of chromospheric condensation heats atmosphere obviously and the temperature in the chromospheric condensation is higher than the original case; the downware velocity of transition region may be greater than 100 km/s at the early stage; when the evaporated material collide at the top of loop, the densityand the presure there increase rapidly, which result in the formation of a shock wave; and so on.
在改善色球辐射损失和精确分辨过渡区的基础上,通过联立求解连续性方程、动量方程和能量方程,构造了一维磁限制性耀斑环在热沉积作用下的大气动力学模型,获得了耀斑热模型下脉冲相早期较为细致的大气演化理论图象,其主要特征是:耀斑对宁静日冕的加热相当迅速,仅2秒钟日冕温度增加即达一个量级,之后日冕温度增加缓慢;脉冲相早期日冕向下速度很小,几乎可以忽略,热传导驱动色球蒸发,其过程较为激烈,蒸发极大速度可达到1000km/s;色球压缩区与色球蒸发几乎同时形成,且在早期其位置总是与过渡区位置重合;色球压缩极大发生在脉冲相早期,其时密度可高于周围约2个量级,向下速度可超过100km/s;色球压缩极大后,其强度逐渐减弱,但宽度明显增大,且渐渐脱离过渡区往色球传播;压缩区内物质温度要高于原先的大气温度;过渡区下降在脉冲相早期相当迅速,可超过100km/s;当蒸发物质在环顶高速相碰时,环顶的密度、压力迅速增大,且温度也有所增加,导致形成激波,其波面以每秒上百公里的速度自环顶向下传播;在脉冲相前期,日冕软x辐射对色球的加热作用可以忽略;等。

The Ludendorff flattening coefficient measures the overall shape, with sunspotmaximum coronas appearing relatively round because of the large number of streamers at all latitudes, and the sunspot-minimum coronas appearing relatively elongated because mainly equatorial streamers remain Fig.
使用Ludendorff测量所有的形状,在太阳黑子活动频繁的区域,日冕的形状相对比较圆,是由于巨大数量的日冕出现在所有的纬度上,在太阳黑子数量少的区域日冕的形状相对拉长,因为在太阳赤道附近余下的日冕。
