flux tube

The results show that the ambient solar wind speed and the ICME transit time errors show little correlation, even after taking into account the angle of magnetic cloud flux tube to the ecliptic plane the correlation is still not obvious.

结果表明，背景太阳风速度和ICME渡越时间并没有明显的相关性，在考虑了磁云通量管轴相对黄道面夹角的影响后相关性仍然不明显。

When the motion of the flux tube is oblique direction, most passage positions appear irregular FTEs, and the signatures of Bz is bipolar distribution.

当通量管在x方向有正或负速度分量即斜向运动时，大部分部位测到的B x呈不规则变化，B z表现为双极分布。

In addition the structure of magnetic flux tube is provided also by simultaneous observation of quite a few lines.

除此之外，还可利用多条谱线的同时观测，获得有关磁力线管结构等方面的资料。
