抗脂酶

The test measured the inhibition of binding between a labeled,monoclonal antibody 3-47-0 and Salmonella pullorum lipopolysaccharide.

该方法基于待检血清样品抑制酶标单抗与脂多糖的结合，以检测鸡白痢和鸡伤寒特异性抗体。

Ultrastructural observation showed that there was a great deal of damage by Cd2+ pollution:The thylakoids of chloroplast and cristae of mitochondria became swollen or vesiculate and disintegrated finally;The nucleus were distorted and the nuclear membrance was disrupted.

但随着毒害的加重，当超出细胞的保护限度，将会导致保护酶活性降低，抗氧化物质含量下降，而丙二醛等膜脂过氧化产物大量产生，膜透性增加，使植物体受害加剧。

Free radical hurts biological large molecules, lets lipid peroxid- ize and damages membrane, the weakening of antiperoxidation system in vivo (vit E, SOD, GSH-PX) will increase the harmful effect of radical on cells.

自由基损伤生物大分子，使脂类过氧化，造成膜损伤；机体抗氧化体系(维生素E，超氧化物歧化酶，谷胱甘肽过氧化物酶等)作用的削弱会加重自由基的细胞毒作用。

After seedling trees of Yunhe Snow Pear were polluted by Pb(superscript 2+), Cd(superscript 2+), synthesis of chlorophyll was restrained, toxic effect of Pb(superscript 2+), Cd(superscript 2+) on seedling trees was intensified, membrane lipid peroxidation damage was increased. And the protective enzymes system start-up of polluted seedling trees enhanced antioxidative enzymes activities of seedling trees.

结论］Pb(上标 2+)、Cd(上标 2+)污染云和雪梨苗，抑制叶绿素的合成，增强超养阴离子自由基O2(上标-对植株的毒害性，使膜脂过氧化损伤程度高，受重金属污染植株启动保护酶系统，以增强植株的抗氧化性。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
