本文以不同涂膜方式的鸡蛋为研究对象,通过测定鸡蛋失重率、蛋黄指数、哈弗单位、蛋黄水分含量及蛋清pH的变化,研究22℃贮藏42 d过程中鸡蛋内部品质变化的规律,比较不同涂膜方式对贮藏鸡蛋品质的影响,并对数据进行拟合,构建动力学模型.结果表明:贮藏期间,未涂膜组(CK)鸡蛋失重率、蛋清pH、蛋黄水分含量均显著增加(P<0.05),哈弗单位则显著下降(P<0.05),不同涂膜方式对失重率、蛋黄指数、哈弗单位及蛋清pH均有显著影响,贮藏温度与鸡蛋的质量、哈弗单位及蛋黄指数等品质指标均呈良好的线性关系.货架期模型表明,亚麻籽油涂膜组(C+LO)鸡蛋能够在贮藏42 d内保持鸡蛋的一级品质,其次是葵花籽油组(C+SO)与未涂膜组(CK).研究结果表明,亚麻籽油对贮藏鸡蛋品质劣变具有显著的抑制作用.

针对高地隙喷雾机自身惯量大、质心高、药箱液体晃动等特点使其在工作中易发生侧倾失稳问题,本文提出设置防波板来抑制药液晃动以提高作业车辆的侧倾稳定性方法.首先基于Fluent仿真软件,建立了不同数量、布置形式的防波板多相流模型,并建立谐波叠加法纵向三维随机路面模型;然后采用VOF法对药箱内液体晃动进行数值模拟,分析药箱防波板数量、布置形式、充液比和三向加速度因素对液体晃动动力学特性的影响.仿真结果表明:药箱防波板不同数量和不同布置形式相比于无防波板时,液体晃动对侧向冲击力平均分别降低了11%、8%,说明防波板
