铝箔交流侵蚀过程的计算机监测(2)

在铝箔交流侵蚀中用计算机、Ａ／Ｄ转换器和编制的软件监测并记录侵蚀反应进程，研究了盐酸、硫酸浓度和电流对铝箔比容的影响，讨论Ｅ－ｔ曲线的响应，对于不同的侵蚀条件，在Ｅ－ｔ曲线上有不同的特征反映。

表观电化学参数对铝箔交流电侵蚀的影响

改变交流电密度 (J)、电解液温度 (T)及盐酸浓度 (ci)侵蚀电容器铝箔 ,并以表观电化学参数(J/ ci T)为依据 ,通过侵蚀铝箔的表面形貌和侵蚀箔比容的变化规律 ,研究了铝箔在纯盐酸中受〔Cl- 〕和〔H+ 〕影响的交流侵蚀机制。

Sediment Movement in Periodic Alternating Current

The present paper summarizes the results of previous studies, including the structure and principle of the rotary ring flume for researching the fine sediment movement, the mechanism of the flume, method of eliminating the influence of the centrifugal force and sediment movement experiments with periodic alternating current. Also included are the experiment-based relationship among sediment concentration, bed shear stress and silt carrying capacity, a proposed erosion-deposition function and bed erosion-deposition calculation together with the results of verification.
