英文摘要: We report the behaviors of the spines in a quiescent prominence from the observations on 2008 January 15 made with Hinode/SOT in H alpha + 0.076 angstrom, H alpha-0.34 angstrom, and Ca II H line filters. Two spines (1 and 2) are visible in this event. In the spacetime plots of the H alpha and CaII intensities, the two spines seem to gradually move closer together, and finally merge, then separate again. Their behaviors are separated into two kinds of typical motions. On the Doppler diagrams, the spine 1 has a dominant redshift, and spine 2 favors a blueshift, which reveals that the spines 1 and 2 firstly display the drifting motions in opposite directions. The former is drifting northward, while the latter drifts southward. Second, both spines display large-scale oscillating motions. Their oscillating velocities, amplitudes, and periods have average values of 3 km s(-1), +/- 5 Mm, and 98 minutes, respectively, indicating a small-amplitude oscillation with a long period. After the sinusoidal fitting, both spines almost exhibit an antiphase oscillating motions. The spine 2 oscillates 135 degrees ahead of the spine 1. Such antiphase oscillations would reflect the coupling of the transverse oscillations of the spines in this prominence.
