英文摘要In this paper, we report quasiperiodic herringbone structures during the impulsive phase of an X-class flare, coinciding with the distinct acceleration phase of eruptive prominence ejection on 2023 December 31. The prominence propagates nonradially in the southeast direction with an inclination angle of similar to 35 .degrees 4. The fast coronal mass ejection (CME) at a speed of similar to 2852 km s-1 drives a shock wave and a coronal extreme-ultraviolet wave. The herringbone structures lasting for similar to 4 minutes take place at the initial stage of a group of type II radio bursts. The herringbones in the frequency range 20-70 MHz are characterized by simultaneous forward-drift and reverse-drift bursts with average durations of similar to 2.5 and similar to 3.1 s. The frequency drift rates of these bursts fall in a range of 1.3-9.4 MHz s-1 with average values of similar to 3.6 and similar to 4.1 MHz s-1, respectively. The speeds of electron beams producing the herringbones are estimated to be 0.04c-0.41c, with average values of similar to 0.23c and similar to 0.11c for forward-drifting and reverse-drift bursts, respectively. The heights of particle acceleration regions are estimated to be 0.64-0.78 R circle dot above the photosphere, which are consistent with the height of the CME front (similar to 0.75 R circle dot) when the shock forms. Quasiperiodic pulsations with periods of 17.5-21.3 s are found in the radio fluxes of herringbones, suggesting that electrons are accelerated by the CME-driven shock intermittently.
