Re-sults:it was shown that Nano MgO had excellent germicidal efficacy to the Escherichia coli and Staphylococcus aureus.To such spore as Bacillus subtilis var.niger spore,Nano MgO also produced good germicidal effect.It was proposed that abrasiveness,alka-linity,electrostatic attraction,and oxidizing power of nano MgO all combined to promote these biocidal properties.

结果： ①纳米氧化镁能有效杀灭大肠杆菌，对枯草杆菌黑色变种芽孢也有显著的杀灭效果；②纳米氧化镁对金黄色葡萄球菌和枯草杆菌黑色变种芽孢有很好的抑菌作用；③纳米氧化物的磨蚀性、碱性、氧化性以及对微生物的静电吸附使它具有抑菌和杀菌作用。

At the across sections of glacial sills and troughs, the density of striations increases gradualy from the side to the centre.

在冰坎和槽谷的横剖面上，从侧部向中部擦痕密度逐渐增加，槽谷的谷壁向谷底的转折处是擦痕密度由小转大的突变点，反映了磨蚀作用不断增强。

The "ice pot" in the Pavilion designed by the JKMM architectural design workshop in Helsinki draws inspiration from the natural pot-shaped holes in the ice-age rocks formed by erosion.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
