摘要In this paper, we present the measurements of the [N II] 205 mu m line for a flux-limited sample of 122 (ultra-) luminous infrared galaxies [(U)LIRGs] and 20 additional normal galaxies, obtained with the Herschel Space Observatory (Herschel). We explore the far-infrared (FIR) color dependence of the [N II] 205 mu m (L-[N II]205 (mu m)) to the total infrared (L-IR) luminosity ratio, and find that L-[N II]205 (mu m)/LIR only depends modestly on the 70-160 mu m flux density ratio (f(70)/f(160)) when f(70)/f(160) less than or similar to 0.6, whereas such dependence becomes much steeper for f(70)/f(160) > 0.6. We also investigate the relation between L-[N II]205 mu m and star formation rate (SFR), and show that L-[N II]205 mu m has a nearly linear correlation with SFR, albeit the intercept of such a relation varies somewhat with f(60)/f(100), consistent with our previous conclusion that [N II] 205 mu m emission can serve as an SFR indicator with an accuracy of similar to 0.4 dex, or similar to 0.2 dex if f(60)/f(100) is known independently. Furthermore, together with the Infrared Space Observatory measurements of [N II], we use a total of similar to 200 galaxies to derive the local [N II] 205 mu m luminosity function (LF) by tying it to the known IR LF with a bivariate method. As a practical application, we also compute the local SFR volume density ((rho) over dot(SFR)) using the newly derived SFR calibrator and LF. The resulting log (rho) over dot(SFR) = -1.96 +/- 0.11 M-circle dot yr(-1) Mpc(-3) agrees well with previous studies. Finally, we determine the electron densities (n(e)) of the ionized medium for a subsample of 12 (U)LIRGs with both [N II] 205 mu m and [N II] 122 mu m data, and find that n(e) is in the range of similar to 1-100 cm(-3), with a median value of 22 cm(-3).
