查询词典 surface area

Under scanning electron microscopy, along with the extension of the culture time, the chondrocytes grew and propagated well on the surface. On 3 weeks, the cells adhered to the surface, and extended the pseudopodia, by which the cells were connected each other. The cells secreted matrix, which deposited around the cells and the surface of meniscus. In some area, the cells formed the structure like cartilage lacuna.

For thin polycrystalline films, especially those with columnar structure, once the diameter of grains on the film surface is larger than the film thickness, the total area of above and under basal planes (film-substrate interface) will be larger than that of side plane. Therefore besides the minimization of boundary energy in traditional bulk material, surface energy, interface energy would be considered due to the anisotropy of surface energy, interface energy being able to drive the grain growth and texture evolution in thin films.

对于薄膜特别是柱状晶薄膜，当晶粒在膜平面内的尺寸大于膜厚时，柱状晶粒的上底面和下底面的面积将大于侧面的面积，因此薄膜中的晶粒生长除像整体材料中的晶粒生长一样考虑晶界能外，还需要考虑表面能和界面能，因为各向异性的表面能和界面能将导致薄膜中的异常晶粒生长和织构变化。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
