本研究以香石竹花为材料，利用中子断层摄影技术，探讨香石竹花干燥过程中失水部位之变化。将花部分固定在旋转盘上，每个投影用热中子照射4s。总中子剂量为6.0× 108 n/cm ~ 2。穿透样品的中子被荧光转换器转换成光子。使用两个反射镜将光子图像引导到冷却的CCD相机。每1°逐步旋转样本，直至180°，即获得180张图像用于CT构建。在干燥处理之前和之后拍摄花的几个切片的水平CT图像。在水平方向CT图像的基础上，还构建了花的垂直方向CT图像。结果表明，干燥处理选择性地去除了胚珠周围的水分。
We present the trial to determine the water deletion part in a carnation flower tissue while drying by neutron computer tomography (CT). The flower part was fixed on a rotating disk and thermal neutrons were irradiated for 4s per projection. The total neutron dose was 6.0×108n/cm2per projection. The neutrons penetrating the sample were converted to photons by a fluorescence converter. The photon image was guided to a cooled CCD camera using two mirrors. The sample was rotated, stepwise, every 1°, up to 180°, i.e. 180 images were obtained for the CT construction. Horizontal CT images of several slices of the flower were taken before and after the drying treatment. Vertical CT images of the flower were also constructed based on horizontal CT images. It was found that the water around the ovule was selectively removed by the drying treatment.
