2、征和功率谱的谱指标特征。本文的主要目的是做出速度场的功率谱，进一步检验临界平衡理论假设的正确性与适用性。文中采用了安装在WIND卫星上的磁场探测器MFI和三维等离子体探测器3DP在1995年1月31日所采集到的总磁场和等离子体速度场数据。并且采用基于小波变换的功率谱分析，做出速度场功率谱密度函数图和磁场功率谱密度函数图。其中横轴为局部磁场和太阳径向向外方向的夹角；纵轴为时间尺度。通过功率谱密度函数图的分析可以得出功率谱随角度变化的分布特征。通过计算机的计算结果表明当天的速度场功率谱显式出各向同性的特征，同时磁场的功率谱也同样显示出了各向同性的特征。这说明临界平衡理论假设并不是普遍适用的。从原始
3、数据看，由于速度扰动和速度化磁场扰动高度相关，笔者认为这可能是产生各向同性的原因之一。遗憾的是本文只针对1995年1月31日的数据进行了考察，无法同其他明显存在阿尔文波时间段的功率谱进行比较。同时当功率谱为各向同性时，功率谱谱指标特征也有待进一步探究。关键词临界平衡；太阳风湍流；功率谱；小波分析；各向异性；中国地质大学（北京）本科生毕业论文ABSTRACTGOLDREICHANDSHIRIDAIN1995,PROPOSEACRITICALBALANCEOFTHEORETICALASSUMPTIONSAFTERELSASSERINTERODUCEANEWVARIBLESINTHEMHDEQUAT

10、毕业论文1前言1950年，ELSASSER对磁流体方程进行了改进，引入了ELSASSER新变量。新变量将磁流体的磁场和动量结合在了一起，不仅将磁流体的动量方程和磁感应方程结合在一起，同时新方程“显式”的描述了反向传播的阿尔文波的非线性相互作用。在此基础上GOLDREICH和SHIRIDA于1995年提出了临界平衡理论。他们假设磁流体中波动的传播效应和反向波动相互作用效应相当。并且将理论应用于太阳风中，得到了太阳风湍流各向异性的结论。理论也给出了垂直于磁场方向和平行于磁场方向的功率谱的谱指数分别是5/3和2。TIMOTHYSHORBURY于2008年的一篇文章中给出了垂直于磁场方向和平行于磁场方
11、向的功率谱的谱指数的观测值，结果与理论符合的很好。JJPODESTA于2009年的一篇文章中进一步细致的研究了局部磁场方向与太阳径向向外方向不同夹角不同时的功率谱谱指标特征，结果同样与理论符合的很好。在HEIDLPLOTS,TIME,COI,NOCLIP0YPADRETURNSTHEPADDEDTIMESERIESTHATWASACTUALLYUSEDINTHE中国地质大学（北京）本科生毕业论文25WAVELETTRANSFORMDAUGHTERIFINITIALLYSETTO1,THENRETURNTHEDAUGHTERWAVELETSTHISISACOMPLEXARRAYOFTHESAME
