结果表明：在日珥中心，运动温度和中性氢密度随高度增加而减少，湍动速度随高度增加而增加；

It is shown : ( 1 ) Near the axis of the prominence , kinetic temperature and hydrogen density decrease whereas microturbulent velocity increases with the rising of height ;

根据多普勒效应，中性束中的氢粒子发出的Hα波长偏离本底的Hα波长，波长偏移量与氢粒子的能量相关，从而在光谱仪上得到多峰Hα谱线。

According to the Doppler effect , the multi-peak H_ α spectra is obtained , which are emitted by the neutral beam and separated from the unshifted H_ α .
