摘要通過與普通酸處理膠圈進行試紡對比,指出了紫外線光照膠圈在實際應用中可降低細紗條干cv值和細節、粗節及棉結等紗疵。When exciting at 1064nm, the fluorescence of the crystal violet ( cv ) in the cv - au sol system will be quenched rapidly and meanwhile its raman signals will also be enhanced at least 105. after addition of some drops hno3 ( 1 + 10 - 2m ), due to the chemical interaction between some cv molecules and hno3, some hcv derivatives will be formed. compared with cv, hcv can be adsorbed on metal surface more easily and tightly so there is some extra enhancement in this condition
結果表明,結晶紫分子?金膠體系中結晶紫分子在1064nm近紅外光激發條件下,其熒光得以大大淬滅,同時拉曼得到了至少不低於10 ~ 5倍的增強;當進一步加入硝酸使得其處于酸性氣氛下時,由於部分結晶紫分子與硝酸發生了化學作用形成了結晶紫分子的單替代衍生物( hcv ) ,而hcv與結晶紫分子相比,更容易吸附在金屬表面,因此結晶紫分子nir - sers還將有很大的增強。The high purity of genomic dna extracted by tripure isolation reagent was observed. dna agarose gel electrophoresis showed that the genome had a high integrity without degradation. and also, spectrophotometric analysis indicated that the genomic dna had no pollution by protein and rna. 2
