This proves that concrete can produce thaumasite in a sulfate environment over 15 ℃, and the existence of Mg2+ can accelerate the formation of thaumasite.

证明水泥混凝土在＞15 ℃的硫酸盐侵蚀环境下亦可生成碳硫硅酸钙，而Mg2+的存在对碳硫硅酸钙的形成过程具有加速催化作用。

The thio sulfate (hyposulfite, or "hypo") is used to developed photographs.

硫代硫酸盐(亦称hyposulfite或「hypo」)则使用于冲洗底片。

Hydrochloric acid and thiosulphate solution react to give sulphur particles which can block the transmission of light. Under this merit, light sensor can be used to collect the corresponding experimental data. Analysing these data can help to find out the relationship between the concentration of solution and the rate of reaction.

由於氢氯酸与硫代硫酸盐溶液反应所释出的硫磺会影响光线进行，因此利用光度感应器便可收集有关的实验数据，透过这些数据的分析便可找出溶液浓度与这个反应速度的关系。

As a result of recent world-widediscussions on the possible harmfulness of sulphites, theJoint FAO/WHO Expert Committee on Food Additives has assessed the intake of sulphur dioxide andrelated compounds, suchas calcium, potassium andsodium hydrogen sulphite; calcium, potassium and sodiummetabisulphite; calcium, potassium and sodium sulphite;and sodium thiosulphate.

由於最近全世界关於硫化物的可能的有害，在食品添加剂的联接FAO/WHO专家委员会的讨论估计了二氧化硫入口和相关化合物， suchas钙，钾和钠氢硫化物；钙、钾和钠偏亚硫酸氢盐；钙、钾和亚硫酸钠；并且钠硫代硫酸盐。

The detection limit of EDTA titrimetric method for sulfate was determined according to a procedure which is basically EPA method detection limit procedure except that it also accounts for the contribution of variability of blank and total hardness on sample results.

在美国环保总署方法检出限程序的基础上，设计了一个能考虑样品空白和总硬度的可变性对样品测量值贡献的方法检出限程序，并按照此程序对EDTA滴定法测定硫酸盐的检出限进行了确定。

For use either indoors or outside, the treatment is ideal for any kind of wall that requires the use of products that are highly transpirable, able to eradicate water, have low capillary absorption, a low content of water-soluble salts and do not form chemical reactions in the presence of sulphates.

这种处理方式可用于室内外环境，具有高度扩散、有效去除水分、毛细吸收、水溶性盐分含量低和不与硫酸盐发生化学反应的特点。

The complex kinetics of ClO2(superscript -) S2O3(superscript 2-) nonlinear reaction system in an unbuffered solution has been investigated in a CSTR.

研究了亚氯酸盐－硫代硫酸盐反应体系在非缓冲条件下的复杂动力学行为。

Dna was extracted from 12 frozen tissues and 35 paraffin embedded tissues, then treated by sodium bisulfite and pcr amplified by specific primers for methylated versus unmethylated dna.

将提取的dna经亚硫酸盐处理后，用甲基化特异性pcr（methylation specific pcr，msp）方法检测blu和arf基因启动子的甲基化状态。

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％。
