1. B “Black ice is a very thin layer of ice.” 可知, 本段在介绍什么是黑冰。 B项 “黑冰是什么?” 符合语境。 故选B。 2. C "When snow or water on the road turns into ice and the temperature goes below 0℃, black ice can form.” 介绍了黑冰形成的原 因,C项 “黑冰是如何形成的...
aThe observation area was covered with a smooth, very thin layer of gypsum in white, thus facilitating to observe the process of crack propagation in successive moments of time during fatigue tests. 在疲劳试验期间,观察面积用光滑,非常薄层在白色在时间的连续片刻报道了石膏,因而促进观察裂纹扩展的过程...

The subthreshold slope of microcrystalline silicon Thin Film Transistor is shown to be highly improved when the thickness of the active layer is enough decreased. In the same manner, the threshold voltage of these TFTs with very thin active layer is shown to be controlled dynamically with high ...
Production of a very thin layer of a first material on a final substrate using a thick layer transfer thinned by implantation and fracture, notably for silicon on insulator structuresThe production of a thin layer of a first material on a final substrate of a second material comprises: (a) ...
The effect of the electric double layer (EDL) of friction surface on lubrication is significant under the condition of very thin lubricating film. This article presents a theoretical evaluation concerning the effect of the EDL on the film thickness and the pressure distribution of the elastohydrodynam...
The products labeled with nano marks in the market now are only traditional products coated with a thin layer of nanometer material, which makes them more abrasion resistant(耐磨), much easier to be cleaned, or oil resisting or moth proof(防蛀). ...
We show that germanium dots can be directly grown by molecular beam epitaxy (MBE) on a silicon (001) surface covered by a thin (1.2-nm-thick) thermal silicon oxide layer. We describe the experimental procedure, which induces the growth of a high density(1011/cm2)of nanometric germanium dot...
Glaze consists of the raw materials of glass, ground together and mixed with water to a creamy consistency. The glaze is sprayed on to the pot which is then heated in the kiln again until it is, in effect, covered with a very thin layer o [translate] ...
aOn the side that was in direct contact with water during the coagulation, a very thin selective layer, not exceeding a few tenths of micrometers, is observed. 在直接联系用水在凝固期间的边,非常稀薄的有选择性的层数,不超出测微表几tenths,被观察。[translate]...
