Study of the standardization of system of measurements for agricultural products

为使本项目为农产品计量体系的标准化，本研究从综合判断出发，按照研究规划进行。本研究通过收集、整理现有的有关农产品品质的资料和试验研究，完成了《农产品品质》第三版，主要研究结果如下：（1）物理特性对稻米品质的测定。(2)颗粒休止角测量的标准化。(3)真实的实时测量粮食的力学性能。(4)蔬菜水果回声测深仪性能的测量标准化。(5)蔬菜和水果光学特性的测量标准化。(6)用化学法、电化学法和光学法对粮食中水分含量进行标准化测量。(7)测量谷物中的水分转移。(8)污泥性质的测量。(9)蔬菜和水果在水中漂浮的特性。(10)谷物机械损伤的测量

To bring this project for the standardization of the system of measurement for the agricultural products, this study was carried out in accordance with the study planning from a synthetic judgment. As the result of this study, the third edition on the properties of agricultural products was accomplished by collecting and arrangement of matterials on properties of agricultural products up to now or by the experimental studies.The main results were as follows :(1) measurement of physical properties on rice qualities.(2) standardization of measurement of the angle of repose of grains.(3) real time measurement of mechanical properties of grains.(4) measurement standardization of the properties of echo sounder of vegetables and fruits.(5) measurement standardization of the optical properties of vegetables and fruits.(6) standardization measurement of water content in grains by chemical, dlectinic and optical methods.(7) measurement of water transfer in grains.(8) measurement of sludge properties.(9) properties of floating in the water of the vegetables and fruits.(10) measurement on mechanical damage of grains.
