• 摘要：研究表明,桑叶氟污染较重时,干茧和丝的质量受到危害,茧层重、粒茧量和公升茧粒等6项指标均显示干茧质量明显下降;在14项丝质量指标中除清洁度和强伸力外,均有明显氟危害影响.

• Abstract：By the quality tests of dry cocoon and silk from the silkworms fed with F-contaminated mulberry leaves, it was shown that fluoride has large effects on the qualities of dry cocoon and silk if the leaves have been contaminated to a serious extent. In this case, some of the six indexes for dry cocoon quality, including silk layer weight of a cocoon, weight of a cocoon, and number of cocoons per litre, are reduced obviously. Except for cleanness, tenacity and elongation of a bave, all the 14 indexes for silk quality have a signifi-cant effect of F-damage. Of them,those having a serious effect of F-contamination include the nonbreaking lenth of a bave, the total conditioned weight of raw silk, the conditioned weight of a bave, the lenth of a bave, the unwinding rate and total dry weight of bave sample etc.
