| Abstract: | An experiment was conducted to freeze and dry pig artery combined with scanning by micro-CT under different primary and second drying temperatures.The optimum drying condition was obtained by calculating dehydration rate of sample,comparing the effect of fast-freeze and slowly-freeze on sample.Besides,it analysed the images of samples' surface wrinkle and scanned one under different conditions. |
