图4 稻谷籽粒低场核磁信号强度和横向弛豫时间T2 反演图谱及各状态水分占比随时间的变化 图4-A，4-C 分别为热风和微波处理后稻谷籽粒横向弛豫时间T2 反演图谱。图4-B，4-D 分别为热风和微波处理后稻谷籽粒各峰所占的比例。UT：未处理样品，HAT-1 h、HAT-2 h、HAT-3 h、HAT-4 h、HAT-5 h 分别为热风处理1 h、2 h、3 h、4 h、5 h 的样品。MW-2 min、MW-6 min、MW-10min、MW-14 min、MW-18 min 分别为在1.29 W·g-1 的微波剂量下处理2 min、6 min、10 min、14 min、20 min 的样品。下同

Fig. 4 The inversion spectrum of LF-NMR signal intensity of rice grains and transverse relaxation time T2 and the water proportion of different state of rice was changed with time under different conditions Fig. 4-A and 4-C were the inversion spectrum of the transverse relaxation time T2 after hot-air treatment and microwave treatment, respectively. Fig. 4-B and 4-D were the proportion of the peaks of rice grains after hot-air treatment and microwave treatment, respectively. UT: Untreated samples. HAT-1 h, HAT-2 h, HAT-3 h, HAT-4 h and HAT-5 h represented the hot air treatment for 1 h, 2 h, 3 h, 4 h and 5 h, respectively. MW-2 min, MW-6 min, MW-10 min, MW-14 min, MW-18 min represented microwave treatment with 1.29 W g-1 microwave doses for 2 min, 6 min, 10 min, 14 min and 18 min, respectively. The same as below
