二氧化硫

SO2 control efficiencies for spray dry scrubbers are slightly lower than wet systems, between 80% and 90% due to its lower reactivity and L/G ratios.

喷雾干燥洗气器的二氧化硫控制效率略低于湿式系统，在 80%和 90%之间，原因在于其稍低的反应性和 L/G 比率。

At present, the urban levels of government, departments and enterprises focus on sewage, pollution abatement is important as a breakthrough point and handle and the promotion of economic growth pattern, and promote industrial restructuring and upgrading, to ensure completion by the end of sulfur dioxide and chemical oxygen demand reduction, respectively, 5% and 4% target.

目前，市区两级政府、有关部门和重点排污企业，正以污染减排为突破口和重要抓手，促进经济增长方式转变，推进产业结构调整和升级，确保年底完成二氧化硫和化学需氧量分别削减5%和4%的目标。

For example, some primary and secondary copper smelting plant is still in use behind blast furnace process, sulfur dioxide utilization rate of only 65%; primary and secondary lead smelting enterprises, commonly used sintering pot lead smelting process, flue gas concentration is low, can not use the sulfur into the atmosphere each year up to 25 million tons.

例如，一些中小学炼铜厂仍处于落后高炉使用过程中，二氧化硫的只有65％的利用率，小学和中学铅冶炼企业，普遍使用的烧结锅炼铅工艺，烟气浓度低，可不使用到大气中的硫，每年达到25万吨。

The fluoride absorption was positively related to respiratory rate of leaf andthe content of free water in leaf tissue,but negatively related to the thickness of lowersurface and osmotic potential with zero expansion pressure of leaf.

9树木对大气氟污染的抗性强弱与树种的气孔总传导度大小负相关，对大气二氧化硫污染的抗性与气孔总传导度和叶组织pH值负相关，树木对大气氟化物的吸收能力与呼吸速率和自由水含量正相关，与膨压为零时渗透势和下表皮厚度负相关。

The results showed that in addition to industrial solid waste, the relationship between foreign direct investment and sulphur dioxide and industrial waste water and soot is obvious; but for Shandong province, the overall impact of the environment is uncertain.

利用1981~2008年山东省实际利用外资额和二氧化硫、工业废水、工业固体的排放量的数据进行了实证分析，结果表明：除固体排放物外，外商直接投资增长与废气、废水变化之间的因果关系较为明显；但是对于山东省环境总的影响并不确定。

The bright and smooth haze was found by Venus Express to be rich in sulfuric acid, created when an unknown process lifted water vapor and sulphur dioxide from lower levels into Venus' upper atmosphere.

金星快车发现明亮而均匀的薄雾中富含硫酸，水蒸汽上升遇到低空中的二氧化硫，经过未知的化学反应，而后上升到金星高层大气中从而形成。

The reaction of sulphur dioxide and oxygen to give sulphur trioxide.

二氧化硫和氧气反应生成三氧化硫。

Acid rain: Sulphur dioxide emissions from coal use are leading to anincrease in the acidity of rain.

酸雨： 由于煤炭使用而造成的二氧化硫排放正在导致降雨中酸度的增长。

Because our country at present every year the acid rain and the sulphur dioxide pollution the economic loss which creates to the ecological environment harm and the human body health influence about 110,000,000,000 Yuan, the close same year gross national product 2%, the next this kind of pollution lost also continues to increase unceasingly.

我国目前每年因酸雨和二氧化硫污染对生态环境损害和人体健康影响造成的经济损失在1100亿元左右，已接近当年国民生产总值的 2%，今后这种污染损失还将持续不断地增加。

In addition, the sulphur dioxide removal process forms solid products.

另外，在二氧化硫去除过程中形成了固态物质。

The concept of equivalent rotationally rigidity is offered and the formula of rotationally rigidity is obtained.
