This gel shrinks rapidly as an electric field with a low supply voltage is applied across it, and the overall shrinking process can be completed in 15 minutes. The gel would swell again when the the electric field is removed. A theoretical analysis and experimental study have been carried out on the kinetics of swelling and shrinking of the disk shape gels. The modeling of kinetics of swelling and shrinking of the disk gels is in good accordance with the experimental results.展开更多

文摘This paper reports the successful synthesis of an ionic gel with good swelling property and high sensitivity to the electric field. This gel shrinks rapidly as an electric field with a low supply voltage is applied across it, and the overall shrinking process can be completed in 15 minutes. The gel would swell again when the the electric field is removed. A theoretical analysis and experimental study have been carried out on the kinetics of swelling and shrinking of the disk shape gels. The modeling of kinetics of swelling and shrinking of the disk gels is in good accordance with the experimental results.
文摘根据 1950 —1995 年共 46 a 的南印度洋船舶气象报资料，按 5°× 5°网格统计的海浪要素进行分析研究。通过分析每月各要素的等值线分布图，得出南印度洋海浪场季节变化特点不如北半球各大洋显著，但仍有较明显的季节变化，只是季节性差异较小，冬季比夏季海浪强盛，相应的平均波高、大浪大涌频率也较大；盛行风浪传播方向、涌浪传播方向基本一致，10°S 以北为季风气候区，而其它海域则信风区常年盛行 SE 向浪，40°S 以南盛行偏 W 向浪。本文提供了南印度洋海域较为翔实的海浪场资料及变化规律。
