Mixed-Morphology Supernova Remnants (MM SNRs) are well known for their unusual center-filled X-ray morphology. Two models have been explained such property, employing different distributions of cold-and-dense gas components around the supernova. To investigate the cooling feature of MM SNRs, we observed the Antlia SNR, a large MM SNR ( 24° in diameter), in far-ultraviolet domain with Spectroscopy of Plasma Evolution from Astrophysical Radiation (SPEAR, aka FIMS). We detected C III λ977 and C IV λλ1548,1551 emission lines, which might be generated as the hot gas of the remnant cool down interacting with the ambient cold gas. The C IV emission line map shows a clumpy distribution, and the temperature profile---inferred from the line ratio of C III and C IV---is increasing near the edge of the remnant. These results are more compatible with the thermal evaporation model than the thermal conduction model, which predicts the edge-concentrated C IV feature and the decreasing temperature profile near the edge of the remnant.
