太阳质子事件预报和射电Ⅰ型噪暴

太阳是一个异常活跃的天体，其爆发过程会对地球周围空间环境产生重要影响. 通常，单个高能质子即足以引起飞行器中微电子器件出现异常，因此太阳质子事件预报是空间天气预报的重要内容. 关于预报模型的参数选择尚有值得改进之处. 研究认为，Ⅰ型噪暴与日冕加热磁重联具有密切关系，可以作为预报参数. 通过两个典型太阳爆发事件的详细资料分析，说明了Ⅰ型噪暴与质子事件及CME的相关性. 

Prediction of Solar Proton Events and Radio Type I Noise Stormorm

The Sun is a very active astronomical object. Its great exploding energy can severely affect the Earth's space environment. Since a single high energy proton is sufficient to damage the normal operation of microelectronic devices in a spacecraft, the solar proton events' forecast is very important in space weather forecast. The prediction model of previous ones needs improvement in some aspects of the choice of prediction parameters. Metric Type I burst is closely related to magnetic reconnection and coronal heating, and therefore can be used as one of the forecast parameters. The paper provides some detailed data of two typical solar eruption events, which have illustrated the correlation between Type I noise storm and proton events, CME. Yunnan Observatory has built a solar radio telescope of 11m diameter, which frequency ranges from 70MHz to 700MHz, and the resolution can reach 200kHz. Its time resolution is programmable between 20ms and 80ms, and the dynamic range can reach nearly 72dB. The radio telescope is located by Fuxian lake about 60km away from Kunming. It can not only observe Type Ⅱ-Ⅳ bursts, but also observe Type I noise, hence plays an important role in prediction of space weather.
