Under these conditions,the product has low viscosity,good water-solubility and excellent chelate ability.

在此条件下得到的产品粘度低，水溶性好，螯合能力强。

The performance changes of weight loss rate, water-solubility treated by oxygen low temperature plasma are studied in the text. We also analyzed the surface chemical structure and surface morphology changes of the PVA film with AFM and Infrared spectra.

本文首先通过氧气等离子体处理PVA浆膜,研究等离子体处理后PVA浆膜的失重率,水溶速率等性能的变化,并用原子力显微镜(AFM)和红外光谱测试并分析了等离子体处理前后PVA浆膜表面形态和化学结构的变化。

The measured parameters of antioxidant defense system included antioxidant enzymes, superoxidant dismutase (SOD), catalase (CAT), selenium dependent glutathione peroxidase (Se-GPx) and glutathione S-transferase (GST); water-solubility antioxidant, glutathione (GSH). DNA single strand break was analyzed as index of DNA damage.

所检测的抗氧化系统包括抗氧化酶——超氧化物歧化酶(superoxide dismutase，SOD)、过氧化氢酶(catalase，CAT)、硒依赖的谷胱甘肽过氧化物酶(selenium-dependent glutathioneperoxidase，Se-GPx)、谷胱甘肽硫转移酶(glutathione S-transferase，GST)及水溶性小分子抗氧化物——谷胱甘肽(glutathione，GSH)，脂质过氧化程度以丙二醛(malonaldehyde，MDA)含量为指标，DNA损伤以DNA单链断裂为指标。
