本研究探討400nm~700nm之可見光對於遠紅外線針織物放射率影響，對其遠紅外線放射率變化情況進行觀測。This research studies the effect of visible light with wavelength 400nm - 700nm on the emissivity of far infrared knitted fabrics of which the change of emissivity was observed.
本實驗照射光源時間為20、40、60分鐘，當光源照射中止時即開始測量數據，In this experiment the irradiation time intervals were 20, 40 and 60 minutes. The data were measured immediately after the irradiation were suspended. 由實驗結果得知，光源照射時間越久樣布表面溫度越高則遠紅外線放射率相對會越高，經光源照射後，因樣本表面提升溫度不同，遠紅外線放射率提升程度也不同，The findings showed that the far infrared emissivity will be relatively higher if the sample fabric surface being irradiated by light source with longer time and higher temperature. After irradiated by light source the rise of surface temperature varies and consequently the rise of far infrared emissivity varies as well. 但遠紅外線放射率約到達0.940~0.975時就會開始趨於平緩，經15分鐘後其放射率約回復到0.934，當遠紅外線聚酯布經過光源照射後遠紅外線放射率皆有所提升。However, the rise of far infrared emissivity began flattened when reached 0.940 to 0.975, and the emissivity returned to 0.934 after 15 minutes. When the far infrared polyester fabrics were irradiated by light source their far infrared emissivity all rose.

要修改時按錯鍵了，第一段修改如下：(末尾增加 far infrared )
