碳钢在NaHCO3+NaCl溶液中的亚稳态孔蚀特征

用动电位极化和恒电位极化法研究了A3碳钢在不同浓度NaCl的0.5mol/LNaHCO₃溶液中亚稳态孔蚀行为。实验发现亚稳态电流波动峰具有快速上升、缓慢下降的特点。亚稳孔出现电位E_m 服从正态分布,随着Cl^-浓度的提高,E_m 值向负方向移动。亚稳孔的峰频变化规律与电位关系不大。恒电位极化时,当电位高于E_m而大大低于孔蚀电位E_b 时,电流波动保持一定时间后会最终消失,并产生直径为微米级的小蚀孔。当电位接近孔蚀电位时,一段时间的电流波动后电流往往迅速上升,最终转变为稳定蚀孔.     

Abrupt climate change：Debate or action

Global abrupt climate changes have been documented by various climate records, including ice cores, ocean sediment cores, lake sediment cores, cave deposits, loess deposits and pollen records. The climate system prefers to be in one of two stable states, i.e. interstadial or stadial conditions, but not in between. The transition between two states has an abrupt character. Abrupt climate changes are, in general, synchronous in the northern hemisphere and tropical regions. The timescale for abrupt climate changes can be as short as a decade. As the impacts may be potentially serious, we need to take actions such as reducing CO2 emissions to the atmosphere.
