derived by using the same method. According to the Eq.\[eq5\] and above parameters of the jets, the total mass ($M_j$) of the cool plasma carried by jets is estimated to be in the range (9.3-14.0) $\times$ $10^{13}$ g. On the other hand, the filament is assumed as a circular slab. The mass of the filament $M_f$ also can be estimated by following equation: $$\label{eq6}
    M_f=n_Hm_H\frac{w_f^2\pi}{4}L_f,$$ where $n_H$ is the total hydrogen density of the filament, $w_f$ is the width of the filament, $L_f$ is the length of the filament. From Fig.\[fig1\], we obtain the filament width ($w_f$) is about 2.0 Mm and the filament length ($L_f$) is about 23.7 Mm. The total hydrogen density $n_H$ in the filament measured ranges about from $3\times 10^{10}$ $cm^{-3}$ [@ste97] to $3\times 10^{11}$ $cm^{-3}$ [@hir86]. Based on the values, the total filament mass ($M_f$) is estimated to be in the range (0.37-3.7) $\times$ $10^{13}$ g. Comparing the $M_j$ with $M_f$, the maximum of the $M_f$ is just about 40$\%$ of the minimum of the $M_j$. Although not all the cool plasma ejected by jets would become the filament material and some of the cool plasma would fall down to the chromosphere, a conservative estimate
