摘要
采用Fourier分析法,对可见光至近红外太阳连续谱强度的时间序列,在消除了仪器响应轮廓及地球大气效应后,通过功率叠加和研究位相之间的相互关系,检测出低l的五分钟振荡模式.但由于各种噪音的消除不彻底,得到的结果是初步的.
The data of time sequence for the solar intensity continuum spectra are analysed by tiding the Fourier analysis, after the instrumental response profile and the Earth's atmospheric effect in the data are removed. Low degree five-minute oscillation is detected by investigating the superpoied power and time coherence in the spectrum. As the noises have not been completely removed the results are preliminary.
