Conclusion］ the improved iodometric method can be used for rapid screening of sulfur dioxide in foods.

结论］ 改良碘量法可以作为食品中二氧化硫残留的快速筛检方法。

Methods］ improved iodometric method and gb method were used as parallel examination of sulfur dioxide in 94 water-solubility foods and 99 non-water-solubility foods.

方法］ 随机采取水溶性食品94件和水不溶性食品99件，分别用改良碘量法和国标法进行检测，比较两种方法检测食品中二氧化硫的符合性。

Results There were about 15 kinds of chemical poisons including vinyl chloride,polyvinyl alcohol,isoparaffin,polyvinylacetate,sodium hydrate,ammonia,acid hydroc,methanol,diesel oil,carbon monoxide,carbon dioxide,sulfur dioxide,nitrogen oxides,ozo...

结果在聚氯乙烯的生产过程中，作业场所存在化学毒物较多，主要包括氯乙烯、聚氯乙烯、聚乙烯醇、过氧化物、异链烷烃类、聚乙烯乙酸酯、氢氧化钠、氨、盐酸、甲醇、柴油、一氧化碳、二氧化碳、二氧化硫、氮氧化物、臭氧、二氧化锰等。

I try to use visual basic language of computer in order tomake it easy to perform LCA.once anyone can input the conditions according torequirment of computer, he will get the final result of LCA ,Then he can design any productor procession with the thought of LCA,even though he knows little LCA or doesn't knowLCA theory.

将计算机应用到水泥-混凝土系统的环境化设计中，完成了配料计算、权重计算、环境综合指标计算等，权重系数计算表明：二氧化碳的环境影响最大，本文叙述了减少二氧化碳的方法，二氧化硫及氮氧化物的环境影响也不可忽视，因此本文也着重论述了减少这两种污染物的方法，并进行了认真探讨。

Total iron ion concentration in the slurry increased as the desulfurization reaction proceeded, which showed that the coal pyrite was being leached. This method can not only achieve high flue gas desulfurization efficiency but also reduce pyretic sulphur from coal.

随烟气脱硫过程的进行，脱硫浆液中的总铁含量不断增加，说明煤中黄铁矿被不断浸出，故此法在脱除烟气中的二氧化硫的同时也降低了煤中的黄铁矿硫。

Objective: To find out the situation of remanent sulfur dioxide in food in Guangdong Province after food decolourant is added to the food.

目的：了解广东省食品漂白剂如亚硫酸钠等添加到食品中后二氧化硫残留量的情况。

Long time, because the main city of Chengdu is located in the hinterland of Sichuan Basin, the seasonal high frequency of calm winds, temperature inversion strength, subject to a special geographical environment and climatic conditions, in a natural state, city over to respirable particulate matter, sulfur dioxide, represented by the proliferation of difficulties in dilution of air pollutants, resulting in a large number of pollutants in the basin, retention, accumulation.

长的时间，因为成都的主要城市是位于四川盆地，平静的季节风高频率的腹地，逆温强度，受特殊的地理环境和气候条件在自然状态，城市对可吸入颗粒物，二氧化硫，由空气污染物的稀释扩散代表的困难，在污染物在盆地，保存，造成大量积累。

I can not make it blossom and suits me

我不能让树为我开花

When temperatures are above approximately 80 °C discolouration of the raceways or rolling elements is a frequent feature.

当温度高于 80 °C 左右时，滚道或滚动元件褪色是很常见的特征。
