论文摘要
迄今为止，很少有研究集中在大于几个parsec的量表上的原始流出反馈上。为了解决这一研究的匮乏，我们研究了候选人的反馈对他们的父云的反馈对$ \ sim $ \ sim $ 110摄氏度$^2 $对W3/4/5综合体及其周围环境的影响。我们的搜索确定了265 $^{13} $ co云，而半径为$ \ sim $ 0.04-17.12 pc。我们通过在湍流和重力结合能来分析流出候选者的物理特性及其宿主云，从而估计流出活动的湍流支持和潜在的破坏作用。我们发现：（1）较大尺寸的云可能会受到反馈的影响； （2）可能的比例间隔为$ \ gtrsim 4.7 $ PC，用于动荡支持和潜在的破坏性效果； （3）如果流出夫妇到恒星形成的密集气体中，对于珀尔修斯臂中的云，则缩放$ \ lyssim $ 0.2-0.4 pc足以足以使流出活动注入能量和动量以保持湍流，而对于本地臂中的云，则尺度为$ \ silace $ \ 0.1-0.1-0.1-0.1-0.2 pc; （4）对于Perseus Arm中的云，流出活动需要一个比例$ \ lyssim $ 0.3-1.0 PC，以使材料有潜在地分散材料，而对于本地臂中的云，该规模为$ \ lyssim $ 0.2-0.6 PC。流出活动的强度可能会影响点值的强度可能会影响点（3）和（4）和（4）和（4）和（4）和（4）和（4）。最后，我们发现流出反馈可能具有改变线宽尺寸关系的能力。
To date, few studies have focused on protostellar outflow feedback at scales larger than several parsecs. To address this paucity of research, we investigate the effects of feedback from CO outflow candidates on their parent clouds over $\sim$ 110 deg$^2$ toward the W3/4/5 complex and its surroundings. Our search identified 265 $^{13}$CO clouds with radii being $\sim$ 0.04 -- 17.12 pc. We estimate the turbulent support and potential disruptive effect of the outflow activities through analyzing physical properties of outflow candidates and their host clouds in terms of turbulence and gravitational binding energy. We find:(1) clouds of larger size might be less affected by feedback; (2) the possible scale break is $\gtrsim 4.7$ pc for both turbulent support and potential disruptive effect; (3) if outflows couple to dense gas where stars are forming, for clouds in the Perseus arm, a scale $\lesssim$ 0.2 -- 0.4 pc is sufficient for the energy and momentum injected by outflow activity to maintain turbulence, while for clouds in the Local arm, the scale is $\lesssim$ 0.1 -- 0.2 pc; and (4) for clouds in the Perseus arm, a scale $\lesssim$ 0.3 -- 1.0 pc is needed for outflow activity to potentially disperse material away from the natal clouds, while for clouds in the Local arm, the scale is $\lesssim$ 0.2 -- 0.6 pc.The strength of outflow activity may affect the values in the points (3) and (4). Finally, we find that outflow feedback probably possesses the power to alter the linewidth-size relation.
