The study of Filaments is one of the hottest topics in solar physics. Recent studies have shown that coronal mass ejections (CME) are closely related to Filaments,which are often accompanied by the onset of two flare ribbons. Therefore,the analysis and study of Filaments can not only enable us to explore the activity phenomenon of Filaments themselves,but also help us to have a deeper understanding of the physical nature of CME and flare and other explosive activities.Since its launch in 2010,the Solar Dynamic Observatory has provided us with a continuous stream of observations at full solar, multiband,and high spatial and temporal resolution,as well as magnetic field data such as optical spherical apparent magnetic field and vector magnetic field.Using high quality observations from the solar dynamics observatory (SDO) and the new vacuum solar telescope (NVST),we have studied the formation and explosion of Filaments in detail. Up to now,the research progress is mainly as follows:(1) by observing the explosive process of two crossing Filaments in the active region, the two flare ribbons,the post-flare loops, the current sheets,the plasmoids and the coronal mass ejection (CME) produced by the eruption of filaments are studied in detail;We report the CSs connecting the lower flare ribbons and the upper erupting filaments for the first time. (2) We studied the formation and explosion of a small scale filament near the center of the sun. The counterclockwise rotation of the negative foot point of the filament forms a s-shaped structure,which increases the Twist of the magnetic flux rope of the filament and reaches the threshold of the kink instability. The small scale wave activity near the filament continuously perturbs the filament and accelerates the eruption of the filament.This paper mainly introduces the research work of Filaments,and through two examples,makes a detailed observation and research on the formation and Eruption process of Filaments,and the research progress is helpful to improve people's understanding of filaments and deepen people's understanding of the formation and Eruption of filaments. The research on filaments can help people understand the physical process of solar eruptive activities deeply and provide observation basis for predicting the relevant space disastrous weather.
