| 摘 要： | 分析ＣｅｐｈｅｕｓＥ中Ｃ１８Ｏ（Ｊ＝１－０）的速度位置图，发现相对于峰速度的红移速度成分主要分布在中心位置附近的核区，而相对于峰速度的蓝移速度成分除了分布在中心位置附近的核区外，还可以在向东和向西北方向的外流中找到。这说明强度分布图中的分子外流的不准直分布是由相对于峰速度的蓝移速度成分的不准直分布所引起的。

| Abstract: | An analysis of the velocity-position maps of C18O (J = 1 - 0) in Cepheus E has revealed that the red-shifted component (relative to peak velocity) is distributed in the central core, while the blue-shifted component (relative to peak velocity) is distributed in the outflows towards the east and the northwest. as well as in the central core. This indicates that the noncollimation of molecular outflow in the integrated intensity map is caused by the noncollimation of the blue-shifted component . |
