日珥整体运动和质量的推导和观测
Derivations and Observations of Prominence Bulk Motions and Mass
摘要：
在这一章中，我们将回顾观测和测量日珥质量和日珥质量中的整体流的技术。测量这些量对于本书中讨论的模型的开发和测试是必不可少的。日珥流是复杂而多样的，从沿日珥脊的相对线性流到灌木丛状日珥流所表现出的复杂湍流模式。测量流动的技术包括用于天空平面内运动的时间片和光流技术，以及使用谱线轮廓来确定沿视线的多普勒速度。日珥的质量测量主要是通过连续吸收测量来完成的，但质量也可以通过云模型和白光测量来估计。
英文摘要：
In this chapter we review observations and techniques for measuring both bulk flows in prominences and prominence mass. Measuring these quantities is essential to development and testing of models discussed throughout this book. Prominence flows are complex and various, ranging from the relatively linear flows along prominence spines to the complex, turbulent patterns exhibited by hedgerow prominences. Techniques for measuring flows include time slice and optical flow techniques used for motions in the plane of the sky and the use of spectral line profiles to determine Doppler velocities along the line of sight. Prominence mass measurement is chiefly done via continuum absorption measurements, but mass has also been estimated using cloud modeling and white light measurements.
