Observed tidal harmonic constants in many stations are used to verify the astronomical tides in the compound fluid model . the wave model is tested by a set of wave flume data at first . then the results are compared by the actual processes of significant wave height in gauging stations 其中复合流场模型中的天文潮利用众多测站的实测调和常数进行验证;波浪模型首先进行了水槽实验的检验,然后在台风过程中,进行了测站有效波高过程线的比较。
Using the two - stream fluid model , the linear dispersion relation is derived assuming a two - dimensional spatial geometry . two cases are considered , one is that the 2d spatial geometry is defined by the plane containing the two counterstreaming electron populations and the perturbation wave vector ( referred as the xy plane ) , and the other is that the geometry is defined by the plane being vertical to the two counterstreaming electron populations ( referred as the yz plane ) 对高能束流和电子回流构成的双流系统,建立冷等离子体流体模型,采用简正模分析方法,分别考虑扰动波矢在平行于电流传播方向的平面(记为xy平面)上和在垂直于电流传播方向的平面(记为yz平面)上这两种情况,推导了不稳定性的色散关系。
