中文摘要:为了探讨富士苹果内部主要成分与其剖面CT值之间线性关系在贮藏期内的变化,使用X射线CT技术,对处于不同贮藏期的苹果进行扫描,获得CT图像及CT值,并测量苹果内部的主要成分含量,建立不同贮藏期CT值与苹果内部主要成分含量的线性模型。经过比较发现,苹果内部pH值及糖度随着贮藏期的增长而增大,而含水率及可滴定酸含量随着贮藏期的增长而降低,同时各成分与CT值的线性相关模型随着贮藏时间的变化也发生了相应变化。将贮藏时间参数引入苹果内主要成分含量的预测模型,并验证其准确性及可行性,结果表明预测模型的平均误差率小于10%,利用以上预测模型进行苹果内部主要成分的无损检测是一种可行的方法。

Abstract:Change of the linear relationship between CT value and major internal components of Fushi apple during storage period was discussed. CT images and CT value were acquired by scanning the section of Fushi apples, and the model of linear relationships between CT value and major internal components was established. The linear relationships in different storage time were compared. It’s clear that the pH value and sugar content increased with the growth of storage time, while moisture content and titrable acidity decreased. The linear relationships have been changed during the storage period. So the storage time was introduced into the predicting model, which was used to predict the internal components of Fushi apple. The predicting model was proved to be accurate and feasible.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
