| 1. | The second part of our work is devoted to the dissipation mechanism of alfven wave in coronal loop
第二个方面是研究冕环中的alfven波耗散机制。 |
| 2. | In this thesis , we investigate the role of alfven wave in the coronal heating process . all the work consists of two main parts
我们从两个方面对这个问题进行了探讨：第一个方面主要地研究了加热日冕的alfven波源。 |
| 3. | Then , torsional alfven waves propagate upwards along the coronal loop and the carried wave energy can make a play in coronal heating
当被激发的扭转alfven波沿着磁通管向上传播到达日冕，其携带的能量就可以加热日冕。 |
| 4. | Using the technique of fourier transformation , we can derive the alfven wave energy spectrum generated from convection turbulence modeled with kolmogroff - like power spectrum
这样，通过计算可以得到磁通管中被激发的扭转alfven能谱。 |
| 5. | With a three wave interaction model , the pump wave mode is found to be strongly modulated by the background fluctuation , accumulated due to alfven resonance near the resonant layer
通过三波共振模型的分析，可以发现pump波能被集聚在共振层附近的大幅度背景扰动强烈调制。 |
| 6. | Then , the obtained energy spectrum of the generated torsional alfven wave is considered as boundary condition of coronal loop to calculate the subsequent wave dissipation
将计算得到的激发扭转alfven能谱做为边界条件代入，可以对扭转alfven波在冕环中的耗散做一些定量的分析。 |
| 7. | In the first part , turbulent motion in convection zone as source to generate alfven waves is studied following lighthill - stein theory , in which the turbulent source was described by nonlinear terms in mhd equations
就是将mhd方程中的非线性项通过fourier变换转化为湍动源项，并采用kolmogroff幂律谱来描述对流层的湍动谱。 |
