in contrast, 15 of the 19 guyots have summit areas greater than 400 square kilometres above 2,500 metres water depth; only 1 of the 15 conical seamounts has a summit area of that magnitude.
而在19座盖奥特中,有15座水深不超过2 500米部分的顶部面积在400平方公里以上;15座锥形海山中只有一座有这样的顶部面积。
20. the compound blends modern, green and efficient architectural standards with references to regional architectural elements, found in the conical shape of the courtroom, the rectangular forms made of reinforced masonry and concrete construction typical of the region.
20. 建筑群兼收现代、绿色和高效的建筑标准,并参考了区域建筑要素,这体现在审判室是圆锥形的,建筑呈长方形,是加固的砖瓦和混凝土建筑物,是这一地区的典型特色。
an erlenmeyer flask, named after the chemist emil erlenmeyer (1825-1909), is different to a beaker in that it comes with an inverted conical base and a cylindrical neck. there are different types of erlenmeyer flasks for laboratory applications: the narrow neck and wide neck forms. depending on the application the flask may have precision grinding to allow good connection to other containers. \t\t\t \t\t\tthe narrow neck reduces the risk of fluid escaping, especially when boiling or during reactions which agitate the contents. \t\t\t \t\t\tan erlenmeyer flask is useful for mixing fluids or accelerating reactions by stirring or shaking, for example. the erlenmeyer flask is particularly suited for a magnetic stirrer, since it can be placed directly on the stirring platform. a round-bottomed flask, by contrast, must be placed on a cork ring on the stirring platform.
锥形瓶的英文名为erlenmeyer flask, 得名于化学家emil erlenmeyer( 1825- 1909) , 与烧杯不同, 它有一个圆椎形的底盘和一个圆柱状的颈部。 对于不同的实验应用, 锥形瓶颈的尺寸是不同的。 这取决于与之相接的磨砂接口的大小 。\ t\ t\ t\ t\ t\ t一般窄颈的锥形瓶可以减少易挥发物质的逃逸。 特别是在蒸馏或是反应激烈时 。\ t\ t\ t\ t\ t\ t锥形瓶在混合流体及通过搅拌或摇动来加速反应时很管用。 例如锥形瓶特别适合与磁力搅拌器合用, 因为它可以直接放在搅拌器底盘上。 而圆底烧杯却只能加个软木环以便在磁力搅拌器底盘上固定 。
