The results show that the indoor air is unpolluted and the main contamination is particulates with diameter of 10 μm or less, total volatile organic compounds and ozone; the pollution mostly comes from personnel, merchandise and outdoor air; the unacceptability ratio of the indoor air quality is 22.64%, so the indoor air is unacceptable; indoor persons have caught sick building syndrome; long time and low concentratio...

结果表明，商场室内处于未污染状况，主要污染物是可吸入颗粒物、总挥发性有机化合物和臭氧；主要污染来源于顾客、商品和室外空气；商场内人员对室内空气的不可接受率为22·64%，室内空气属于不可接受；室内人员已有病态建筑综合症发生；长时间低浓度污染，是室内污染的重要特征；室内人员对商场的温度、相对湿度和室内光照度、视觉环境等满意程度很高。

Some factors to influence the silicon content of hot metal were proposed on the basis of the experiment in the lab: increasing the binary basicity is favorable to desiliconization; the oxide in slag debases the silicon activity and is of great advantage to desiliconization; Al2O3 and SiO2 are disadvantageous to desiliconization, the volatilization content of SiO2 in coke increases with increasing smelting temperature, leading to increase the silicon content of hot metal; the silicon content of hot metal increases with increasing the drip zone's altitude.

在实验室进行了降低铁水中硅含量的实验，得到了铁水中硅含量的影响因素：提高二元碱度有利于降硅；增加渣中氧化物可降低SiO2的活度有利于降硅；Al2O3和SiO2不利于降硅；冶炼时焦炭中SiO2的挥发量随温度的升高而增多，使铁水中硅含量增加；随着滴落带高度的增加，铁水中硅含量不断增加。

The anion has as follows 8 big benefit: Sterilize surpass the oxygen negative ion free radical but kill various pneogaster infectious disease bacterium; Dust removal makes air middle dust heavy getting together, suspension pellet the brute force is collected; Deodorization dislodges various the peculiar smell living , bad smell , improves a bag; Eliminate cigarette smoke fog , dust in wiping out air rapidly , completely eradicate the second-hand cigarette; The various deleterious chemistry volatilizes a gas , wipes out "the invisible killer " in getting rid of poison dislodging air; Work efficiency, removes health care rise becoming fagged , improve the heart-lung function, strengthen the human body immunocompetence; Improve the looks making an epithelium bring negative charge along , make germs lose the go at ability to the cell , keep skin glossy; Except that static electricity is positive static electricity in general in life, will be physically and mentally healthy to the human body bringing about hidden trouble, the anion has an effect to neutralize this static electricity.

负离子有如下8大好处：杀菌——超氧阴离子自由基可杀灭各种呼吸道传染病菌；除尘——使空气中尘埃聚沉，强力收集悬浮颗粒；除臭——去除各种生活异味、臭味，改善生活环境；消烟——快速消灭空气中的烟雾、尘埃，杜绝二手烟；去毒——去除空气中各种有毒化学挥发气体，消灭&隐形杀手&；保健——提高工效、消除疲劳，改善心肺功能，增强肌体免疫能力；美容——使上皮细胞带负电荷，使病菌失去对细胞的攻击能力，保持皮肤光滑；除静电——生活中一般为正的静电，会对人体身心健康带来隐患，负离子有效中和这种静电。

In addition, UV ink safe solvent emissions, flammable and does not pollute the environment, in the business card printing and membership card in the making of active ingredients, you can almost 100% of the land into the monlchamus membrane, not with inking and 50% water-based ink and, therefore, greatly reducing the plates and rollers boilouts, saving time and materials to food hygiene demanding packaging business card printing and membership card making products.
