冰冻环境下玉米含水量的测定
Measuring of Water Content in Corn under Freezing Environment
摘要
Abstract
In order to rapidly measure the water content in corn under the freezing environment, we put forward the microwave-unfreezing capacitance method in the article, illustrated the measuring principle of the system, and analyzed the nonlinear compensation between capacitance and water content. The results show that the measuring system has reached the following indexes: water-content measuring ranging from 6% to 30% , testing time 150 minutes, testing precision ≤0.6% .repeatability error ≤0.4% , testing temperature ranging from - 40 ℃ to 30 ℃ .关键词
