摘要: 采用一维粒子模拟程序研究了由温度各向异性的电子激发的哨声波。结果表明，当电子等离子体频率和电子回旋频率的比值足够大的时候，和比值较小的情况相比：电子的垂直温度和平行温度的比值将会下降的很快；哨声波的强度迅速增强；哨声波的主频率及其对应的波数将会变小，静电波的影响急剧削弱。

Abstract: Adopting one dimensional particle-in-cell (PIC) simulations, we present a study on the evolution of the electron whistler waves driven by electron temperature anisotropy. Simulating results show that the electron temperature anisotropy can excite the whistler waves. If the ratio of electron plasma frequency to cyclotron frequency is large enough, the electron temperature anisotropy will drop rapidly which lead to the amplitude of whistler waves becomes very large.And also the frequency and wave number of the dominant whistler waves become smaller than those in the case with a smaller ratio.Especially, the effect of electrostatic waves become less important.
Key words: temperature anisotropy；whistler wave；particle-in-cell simulation
