It is widely recognised that filament disappearances or eruptions are frequently associated with Coronal Mass Ejections (CMEs). Since CMEs are a major source of disturbances of the space environment surrounding the Earth, it is important to investigate these associations in detail for the better prediction of CME occurrence. However, the proportion of filament disappearances associated with CMEs is under debate. The estimates range from \(\sim\) 10 to \(\sim\) 90% and could be affected by the manners to select the events. In this study, we aim to reveal what parameters control the association between filament eruptions and CMEs. We analysed the relationships between CME associations and the physical parameters of filaments including their length, maximum ascending velocity, and direction of eruptions using 28 events of filament eruptions observed in H\(\alpha\). We found that the product of the maximum radial velocity and the filament length is well correlated with the CME occurrence. If the product is larger than \(8.0 \times 10^{6}\) \(\text {km}^{2}\) \(\text {s}^{-1}\), the filament will become a CME with a probability of 93%, and if the product is smaller than this value, it will not become a CME with a probability of 100%. We suggest a kinetic-energy threshold above which filament eruptions are associated with CMEs. Our findings also suggest the importance of measuring the velocity vector of filament eruption in three-dimensional space for the better prediction of CME occurrence.

广泛认识到，丝状体消失或喷发经常与冠状物质弹射（CME）相关。由于CME是地球周围空间环境扰动的主要来源，因此详细研究这些关联对于更好地预测CME发生是很重要的。然而，与CME相关的丝消失的比例尚在争论中。估计范围从\（\ sim \）  10到\（\ sim \） 90％，并且可能会受到事件选择方式的影响。在这项研究中，我们旨在揭示哪些参数控制细丝爆发与CME之间的关联。我们使用H \（\ alpha \）中观察到的28个细丝喷发事件，分析了CME关联与细丝的物理参数之间的关系，包括其长度，最大上升速度和喷发方向。我们发现最大径向速度和长丝长度的乘积与CME的发生密切相关。如果乘积大于\（8.0 \ times 10 ^ {6} \） \（\ text {km} ^ {2} \） \（\ text {s} ^ {-1} \），则灯丝将成为CME的概率为93％，并且如果乘积小于此值，它将不会成为CME的概率为100％。我们建议动能阈值，高于此阈值的细丝爆发与CME相关。我们的发现还表明，在三维空间中测量细丝喷出速度矢量对于更好地预测CME发生的重要性。
