硫酸盐

Thus, SRB were likely to reduce sulfates to sulfides simultaneously with petroleum oxidization, and directly or indirectly reduce hexavalent uranium U to tetravalent uranium U to precipitate pitchblende.

于是，利用烃类作为生存的碳源，硫酸盐还原菌将硫酸盐还原的同时，直接或间接地把六价铀U还原成四价铀U，导致沥青铀矿形成。

Cement concrete may undergo the thaumasite form of sulfate attack when it is exposed to low temperature, high humidity, sulfate, carbonate and adequate water for a long period of time.

TSA侵蚀是水泥混凝土在低温、高湿、硫酸盐与碳酸盐长期作用下发生的一种特殊的硫酸盐侵性形式。

X-ray diffraction, scanning electron microscope, energy dispersive spectrum and laser Raman spectrum analysis were used to identify thaumasite in paste sample stored in 10% of MgSO_(4) solution at different temperatures .

钙矾石型和石膏型等硫酸盐侵蚀破坏机理已得到广泛研究与认同，然而另一种硫酸盐破坏类型———碳硫硅钙石型却没有受到应有重视。

Consists of pinted or unprinted sheets,shavings,guillotined books,quire waste,and cuttigs of white sulphite or sulphate ledger,bond,writing paper,and all other papers which have a similar fiber and filler content.

用漂白亚硫酸盐浆或漂白硫酸盐浆制得的账簿纸，证券纸和书写纸等的边角料，以及切开的书籍，整刀废纸，带有印刷油墨或没有印刷油墨的整张纸和纸边等，也包括以同类浆种和填料含量制得的所有其他纸张。

Our results indicated that (1) aortic rings with and without endothelium precontracted by NE to decreased pH induced a relaxation; aortic rings with and without endothelium to increased pH induced a contraction; there is no significant difference in presence and absence of endothelium .(2)NO levels had no significant change in isolated aortic rings presence and absence of endothelium to decreased pH and increased pH ;(3)sulfite levels in isolated aortic rings with endothelium reduced to decreased pH and increased pH. sulfite levels in aortic rings without endothelium had no remarkable change.

结果：①NE预收缩后，pH值降低对内皮完整和去除内皮胸主动脉血管环呈舒张作用；pH值升高对内皮完整和去除内皮胸主动脉血管环呈收缩作用；内皮完整组与去内皮组相比无显著性差异；②pH降低和升高对内皮完整和去除内皮血管环中NO含量无显著性影响；③pH降低和升高均可使内皮完整血管组织中亚硫酸盐含量减少，对去内皮血管中亚硫酸盐无显著性影响。

According to the testing results of high-performance concrete in sulphate erosion environment at Nanjing underground railway project,a prognosticating model of sulphate-resistance erosion is established,which is based upon the disintegration law of concrete,and the project service life is prognosticated by using this model.

根据南京地铁工程高性能混凝土在硫酸盐侵蚀环境下的试验研究结果，初步建立了基于混凝土衰变规律的抗硫酸盐侵蚀耐久寿命模型，并对该工程进行了寿命预测。

The temperature is controlled so as to reduce the decomposition of cobalt and copper sulphate to a minimum.

温度控制的要求为既有利于鉄硫酸盐最大限度的分解；而又能使銅、鈷硫酸盐极少分解。

Inexpensive sudsing ingredients like sulfates can strip the hair, fading color faster and drying out strands, so look for a sulfate-free shampoo, available at salons from brands like Tigi Bed Head (their Superstar line is sulfate-free) or Terax, and at the drugstore from Freeman Beauty or Jason Natural.

答：您在哪里购买洗发水不要紧，廉价的sudsing成分像硫酸盐一样可以快速地褪色，所以寻找一个不含硫酸盐的洗发水，可在美容院找到的品牌如Tigi或在自由人美容或杰森自然这样的杂货店找到的Terax

Lead the vitriol canvasses business to lead the item of money Business enterprise brief introduction: The Hebei JiHeng group limited company with the fine chemical engineering product produce for predominate the industry, gather the section work as comprehensive sex business enterprise group of the integral whole, the main foundation chemicals contain chlorine gas, ion film alkali, diaphragm alkali, sulfuric acid, methyl alcohol...etc., is a scale of Asia biggest, the world is secondary to disinfect a production base, China is biggest to produce the base and China over the vitriol north China the biggest solution in region painful raw material in hot town medicine produces the base.

过硫酸盐招商引资项目企业简介：河北冀衡集团有限公司是以精细化工产品生产为主导产业，集科工贸为一体的综合性企业集团，主要基础化学品有氯气、离子膜碱、隔膜碱、硫酸、甲醇等，是亚洲规模最大、世界第二的消毒剂生产基地，中国最大的过硫酸盐生产基地和中国华北地区最大的解热镇痛原料药生产基地。

It is shown that the main minerals in the slag are quartz, gypsum, mullite and hematite; an obvious characteristic apex of gypsum appears in the DSC curve when dehydrating but the apex is low total amount of SiO2, SO3, Al2O3, CaO and Fe2O3 is above 80%; there are several kinds of sulphates, not only calcium sulphate but also other sulphates with high solubility.

结果表明，电解锰渣中的主要结晶矿物为石英、二水石膏、莫来石及赤铁矿，电解锰渣有比较明显的石膏受热脱水峰，但峰值小；电解锰渣中SiO2、SO3、Al2O3、CaO和Fe2O3的总量占80%以上；电解锰渣中硫酸盐有二水石膏，也有含量较高的大溶解度硫酸盐。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
