多离子成分空间等离子体中斜传播波的混杂共振：（Ⅱ）实验观测与波模识别

HYBRID RESONANCE IN A MULTI￣SPECIES PLASMA:(Ⅰ) WAVE OBSERVATION AND WAVE MODE IDENTIFICATION

在分析ＡＲＣＳ３探空火箭记录到的由人工离子束激发的低频等离子波的特征和激发机制的过程中，提出了多离子成分冷等离子体中的一般混杂共振和一般混杂波的概念，给出了斜向传播冷等离子体波的混杂共振条件．在上述理论的基础上，考虑了电子、氧离子、氦离子和人工氩离子束的贡献，计算出ＡＲＣＳ３实验条件下的等离子体介电函数，并用等离子体波模识别的方法，识别出频率在１８０Ｈｚ。附近的最强波峰乃是Ｏ＋－Ｈｅ＋双离子混杂波．

During the experimental periods of the sounding rocket ARCS3, some strongharmonics-like waves were received. To study the wave mechanism quantitatively, the expressions of the logitudinal dielectric function were derived and a new concept of bihybrid wave and bihybrid resonance were proposed. We infer that the strongest peaks for ARCS3 were corresponding to the 0+-He+ bihybrid waves.
