查询词典 hard surface

When the ground was partially bare of snow, and a few warm days had dried its surface somewhat, it was pleasant to compare the first tender signs of the infant year just peeping forth with the stately beauty of the withered vegetation which had withstood the winter —— life-everlasting, goldenrods, pinweeds, and graceful wild grasses, more obvious and interesting frequently than in summer even, as if their beauty was not ripe till then; even cotton-grass,cat-tails, mulleins, johnswort, hard-hack, meadow-sweet, and other strong-stemmed plants, those unexhausted granaries which entertain the earliest birds —— decent weeds, at least, which widowed Nature wears.

土地上有一部分已没有了积雪，一连几个温暖的日子把它的表面晒得相当的干燥了，这时的赏心悦目之事是用这新生之年的婴孩期中各种初生的柔和的现象，来同那些熬过了冬天的一些苍老的植物的高尚的美比较，——长生草，黄色紫苑，针刺草和别种高雅的野草，往往在这时比它们在夏季里更加鲜明，更加有味，好像它们的美非得熬过了冬才到达成熟时期似的：甚至棉花草，猫尾草，毛蕊花，狗尾草，绣线草，草原细草，以及其他有强壮草茎的植物，这些都是早春的飞鸟之无穷的谷仓，——至少是像像样样的杂草，它们是大自然过冬的点缀。

采用密度泛函数理论法计算结果表明，苯并噻吩的电负性χ为2.638，属软碱类物质；由于Ag^＋为软酸，活性炭负载Ag^＋离子，增加了其局部表面的软酸，从而增强了对苯并噻吩硫化物的吸附；由于Ni^2＋、Cu^2＋和Zn^2＋离子属交界酸，负载Ni^2＋、Cu^2＋、Zn^2＋离子增加了活性炭表面的交界酸，也在一定程度上提高了其表面对苯并噻吩硫化物的吸附；当活性炭表面负载了硬酸性Fe^3＋或Co^3＋离子，其局部表面硬酸增大从而降低了其对苯并噻吩的吸附。
