英文摘要	在回旋波共振准线性理论基础上建立了自恰描述质子和氧离子各向异性温度和整体速度的双离子流体模型,求得数值解,并与UVCS观测相比较.发现在波谱斜率固定的假设下,模型的数值结果虽然与观测有相同趋势,但不能在误差范围之内解释全部观测现象.进一步的研究需要考虑波谱形状的自洽演化.; A set of equations are developed for describing the spatial evolution inthe polar corona of anisotropic multi-ion-fluid properties based on theheating and acceleration by ion-cyclotron resonance. Numericalsolutions of this equation set are used to make a comparison with therecent observations by UVCS on SOHO (Kohl et al. 1998). If weassume that the spectrum of the cyclotron waves has a fixed slop, -2,the model results can describe the UVCS observations for Helium(assuming for protons also) and for either the bulk speed of O{+5ions or the effective perpendicular thermal speed of O+5 ionsrespectively if further assuming different amplitude of the waves. However wecan not describe both speeds with single wave amplitude. It is suggestedthat the fixed spectrum slope assumption, which is widely used in thestudy of this topic, may not describe the real situation in corona.; 国家自然科学基金; 国家科研项目; 高等学校博士学科点专项科研项目; 中文核心期刊要目总览(PKU); 中国科学引文数据库(CSCD); 0; 3; 201-207; 20
