alfven 中文意思是什麼
alfven
解釋
阿爾文-
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
就是將mhd方程中的非線性項通過fourier變換轉化為湍動源項，並採用kolmogroff冪律譜來描述對流層的湍動譜。 -
In this thesis, we investigate the role of alfven wave in the coronal heating process. all the work consists of two main parts
我們從兩個方面對這個問題進行了探討：第一個方面主要地研究了加熱日冕的alfven波源。 -
The second part of our work is devoted to the dissipation mechanism of alfven wave in coronal loop
第二個方面是研究冕環中的alfven波耗散機制。 -
Then, torsional alfven waves propagate upwards along the coronal loop and the carried wave energy can make a play in coronal heating
當被激發的扭轉alfven波沿著磁通管向上傳播到達日冕，其攜帶的能量就可以加熱日冕。 -
Using the technique of fourier transformation, we can derive the alfven wave energy spectrum generated from convection turbulence modeled with kolmogroff - like power spectrum
這樣，通過計算可以得到磁通管中被激發的扭轉alfven能譜。 -
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
通過三波共振模型的分析，可以發現pump波能被集聚在共振層附近的大幅度背景擾動強烈調制。 -
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
將計算得到的激發扭轉alfven能譜做為邊界條件代入，可以對扭轉alfven波在冕環中的耗散做一些定量的分析。
