Solar radio bursts are usually accompanying with solar flares. The complicated radio spectrum detected in solar radio bursts contained a lot of important information on their source region including physical environment and emission mechanism. Especially, because of their morphologic features of short duration, rapid frequency drift, complicated types and so on, the microwave fine structures could bring out rich important information on the source region such as the complicated configuration of magnetic reconnection, the movement of energetic particle, etc.

太阳射电爆发通常发生在太阳耀斑期间，它携带着爆发源区的物理环境以及辐射机制等诸多重要信息，尤其是微波爆发的精细结构，持续时间短、变化快、结构复杂，可以反映重联过程复杂的磁场结构、高能粒子运动等许多特征。

This burst waveform has benefits compared to a continuous wave emission in that the laser peak power can be very high for measuring long distances, yet the average power can be kept low for eye safety. And more, the pre-amplified optical receiver possessing temperature compensation and feedback resistance noise compensation is designed which is based on the noise spectrum density theory of silicon avalanche-photodiode.

At the eclipse of 1870, a more complete set of emission lines from the chromosphere was observed;it is still known as the 'flash spectrum' from the way it flashes into view as the Moon completely covers the solar photosphere.

在1870年的一次日蚀中，更多来自色球层的完整的射线被观测到，当月球完全挡住了太阳的光球时其仍被认为是闪烁的射频频谱而被观察到。

The fluorescence signal revealed by this process is specific and exhibited in the near red spectrum region with emission maxima at 595nm, and it could be competitively inhibited by menadione.

萤光分子所释放出来的长波长讯号(595nm)具有独特的识别性质并且靠近红外光之区域范围，而萤光分子的释放会被维他命K所抑制。
