That regulation is the latest of six new rules intended to rein in emissions of hazardous pollutants from factory and power-plant smokestacks, including soot, mercury, sulfur and nitrogen oxide. 这项规定是旨在限制工厂和发电厂的烟囱排放有害污染物的六项规定之一,被限制的污染物还包括烟灰、汞、硫,以及氮氧化物。
A primary cell consisting of a zinc anode, a cathode of mercury oxide, and an electrolyte of potassium hydroxide. 由锌正极汞阴极氢氧化钾电解液组成的电池。
The kinetics of mercury electrode in potassium hydroxide solution containing mercuric oxide 汞电极在含氧化汞氢氧化钾溶液中的动力学
Less than 8% mercury oxide can be reduced to elemental mercury, influenced by HSO~-_4 ions and metal ions present in the liquid; a higher SO_2 concentration boosts the reduction of mercury oxide. 少于8%的氧化汞可以被还原为单质状态的汞,这种转化与浆液中硫酸氢根离子和金属离子有关,较高的SO2浓度有利于促进氧化汞还原作用的发生。
