The magnetic properties of the newly emerging flux
--------------------------------------------------

From the Fig.\[fig5\] (a) and the analyze in the section.\[sec3.2\], we find some newly emerging flux presented in vicinity of the filament south-western footpoint during the formation of the filament. Previous investigations have shown that many jets have a close relationship with newly magnetic flux emergence [@shi98; @rao16; @hon17]. Thus, these newly emerging flux may play important role in the jets and the magnetic structure of the filament. In other words, these newly emerging flux may be a source of supplying mass and energy for the filament. In order to investigate the properties of newly emerging flux
