【摘要】 本文阐述用微波水分测定仪确定蚕茧含水率的方法,它是用在1983至1984年春、夏、秋三期饲养的同一品种的家蚕茧进行的。铡定时无需削剖茧壳,因而可以快速试验,不破坏蚕茧。与一般测定茧壳的含水率不同,作者测定的为鲜茧的总含水量。发现微波测定值与鲜茧的总含水量有很好的相关性,当前者减少时,后者则增加。此外,发现总含水量与周围的湿度、茧质等因素也有关。所以这是一种可以快速测定蚕茧含水率的方法,为评定茧质的优劣提供依据。更多还原

【Abstract】 This paper describes experiments which were carried out to test moisture content in fresh cocoon of the silkworm in rearing seasons of spring, summer and autumn in 1983 and 1984 by microwave moisture instrument.Cocoons produced from the same silkworm race were used as test materials, Because it was unnecessary to cut open the cocoon shell, it could be carried out very quickly without destroying the fresh cocoon. It was found there was correlation between the testing value of the microwave moisture instrument and the percentage of moisture in fresh cocoon. The former would decreas as the latter was increased. Moreover, it was found that the bulk percentage of moisture in fresh cocoon was influenced by such factorS as air humidity, cocoon quality etc. So this is a quick me-.thod which offers reasonable basis for estimating the cocoon quality.更多还原
