查询词典 coarsening

The experiment of pretreatment shows that polyurethane foam can be washed clearly in both organic and chemical unoil, good effects of coarsening can be gained only if polyure foam can be squeened repeatly and uniform mass loss between 2.0 and 3.0mg·cm~(-3). The result of activation is perfect even if the cheaper silver nitrate instead of expensive palladium bichloride is used as active agent in the experiment. The influence on quality of chemical plating, conductivity, depositon rate by the kinds of reduction, silver contents, PH and stabilizing agent was studied.

颗粒粗化方向及形态依赖于应力轴取向，[001]取向中的γ′颗粒沿[001]方向粗化成rod结构；[110]取向中的γ′颗粒沿[100]和[010]方向长大，形成'〓'结构；而[111]取向中的γ′颗粒没有表现出沿任何方向上的定向粗化趋势，只是以毛细驱动方式各相同性长大。

The modification of the Gladman's model may then be proposed by the comparison of different models of grain coarsening with assumption of uneven in convexo-concave interface along grains. The modified Gladman's expression is given as: R_o =πr/3f_v(3/-2/Z) that may fairly predict the actual grain size observed.

The deep water deposition means the deposition in the area where the water depth is larger than 30 meters, in which the major sediments are coarse sand and gravel. This kind of deposition is the relic deposition formed by the Pleistocene alluvial-lacustine deposition reworked under modern channel currents actions, and ususally the Holocene acummulation lack in the deep waters. The transitional zone deposition is the deposition between the low tidal level line and the 30 meters isobath, where the sediment types is changeable and the grain sizes are gradually coarsening from the low tidal line to the deep water area. This kind of deposition is developed by the deep water eroded sediments sorting under the transitional zone current action. The different types distributed along the isobath. The tidal flat deposition is the fine sediment deposition on the tidal flat which is flo sedimentation of the silty clay under the tidal flat dynamic action and ususally developed fluid mud on the lower tidal flat. The channel mouth deposition is the deposition in the channel mouth area. According to the sediment types, it includes sand deposition where there are coarse sediments supply and silt deposition where there are only fine sediments surpport.
