This Letter presents a calculation of the power spectra of weakly turbulent Alfvén waves and fast magnetosonic waves ("fast waves") in low- plasmas. It is shown that three-wave interactions transfer energy to high-frequency fast waves and, to a lesser extent, high-frequency Alfvén waves. High-frequency waves produced by MHD turbulence are a promising explanation for the anisotropic heating of minor ions in the solar corona.
本信函给出了低密度等离子体中弱湍流阿尔文波和快磁声波（“快波”）功率谱的计算结果。结果表明，三波相互作用将能量转移到高频快波，较弱程度上也转移到高频阿尔文波。磁流体动力学湍流产生的高频波是对日冕中次要离子各向异性加热的一个有前景的解释。
