    摘要:

    小麦比重实验的2个关键参数是小麦试样质量和测试用酒精体积。针对我国5个地区的小麦,研究不同试样质量和酒精体积对小麦比重的影响。结果表明,随着小麦试样质量的增加,小麦比重逐渐增加,最终趋于稳定;酒精体积对比重影响不大。现有小麦比重实验标准所采用的试样质量偏少,导致小麦比重测定结果偏低。对比研究表明,小麦比重实验的试样质量应不少于100 g,远大于现有标准推荐的10 g。

    Abstract:

    The mass of wheat sample and the volume of alcohol are key parameters in specific gravity test of wheat. The effect of sample mass and volume of alcohol on the specific gravity of wheat are studied with wheat samples from five regions in China. The results showed that the gravity increased gradually along with the increase of the mass of wheat samples, until to a steady value finally; while the volume of alcohol has little effect on the specific gravity of wheat. The measured value of wheat sample mass in existent specific gravity experiment standard is smaller than that obtained in this study cause the measured specific gravity lower than actual. The contrast test showed that the mass of wheat sample should not less than 100 g in the specific gravity test, which is far more than 10 g recommended in the current standard.
