The electroless plating with osmosis was improved by using hydrazine as reducer, so the plated Pd film is pure and not alloyed.
对利用渗透作用的化学镀新工艺进行了全面的改进,对陶瓷管所处环境、镀液浓度、沉积温度和镀膜时间以及对钯层沉积量和表面形貌的影响进行了系统的研究。
Electroless plating with an osmosis technique will be the process with the bright future for Pd-composite membrane making.
以多孔基质材料为底膜,将渗透作用应用于制备工艺是具有发展前景的新方法。
The thermal penetration thickness tends to increase with the seepage fl.
计算结果表明,高温气体对导管内颗粒料层的热渗透作用主要是在渗流入口端区域,增大入口渗流速度以及减少给料量,导致气固温度沿轴向下降速度减慢,热渗透深度扩大, 热渗透作用区域内的物料温度水平提高。
Theemphasis was paid on the seepage force in terms of its contribution to the motion in media and property of stressstates induced by seepage.
其中,从力的运动效果和对应应力状态性质两方面讨论了渗透作用力,证明了水力等效连续介质中渗透作用力运动效果等效的必然性和对应应力状态性质的一致性。
Diagenesis,tectonization,capillarity,differential osmosis and filling are the main mechanisms of the seal formation.
成岩作用、构造作用、毛细管力作用、差异渗透作用和充填作用等是压力封闭层形成的主要机制。
