Meanwhile, the analysis ofreproducibility and recovery rate was also probed into in detail; fourthly, theform of cuprum and zincum extracted with M3-dithionze method as well asthe relativity of the content of cuprum and zincum between arid soil and wetsoil were discussed here in order to prove the categoricalness of this method.

在此基础上，对M3-双硫腙法与常规分析方法进行了相关性研究，并对M3-双硫腙法的重现性和回收率作了分析，同时为了更完整地说明本法的完备性，对于本法提取的铜的形态；干、鲜土中铜、锌含量的相关性等问题，本文也进行了分析探讨。

So the cobalt can not only form cobalt self-existent mineral by combining with sulphur or analogous sulphur elements, but also form cobaltiferous sulphides or analogous sulphides and cobaltiferous silicates minerals by isomorphism with Fe, Ni, Mn, Mg, etc.

因此钴不仅可以与硫或类硫元素等离子形成独立钴矿物，而且还可以与铁、镍、锰、镁等离子类质同像，进入铁、镍、锰和镁等矿物晶格，形成含钴的硫化物、类硫化物或硅酸盐。

Sulphur-containing amino acid of transgenic crowtoe plants analysis showed that the content of sulphur-amino acid of transgenic zeolin crowtoe plants was significantly higher than that of the content of the transgenicγ-zein crowtoe plants and non-transgenic crowtoe plants (P.01), but there was no significant difference between the transgenicγ-zein plants and non-transgenic plants.

含硫氨基酸数据分析表明，转zeolin基因百脉根植株含硫氨基酸含量极显著高于转γ-zein基因百脉根植株和非转基因百脉根植株的含量(P.01)，但转γ-zein基因植株与非转基因植株间差异不显著。

Starting with two reactive methylene compounds, ethyl cyanoacetate and malononitrile, two 5-amino-1H-pyrazoles were prepared through the intermediates ketene dithioacetal.

从两个活泼亚甲基化合物开始，经过乙烯酮二硫代缩醛中间体，合成了两个5-氨基-1H-吡唑，以这个两个化合物为中间体，与芳香族和脂肪族α-溴代酮反应，而后经酸催化亚胺化互变异构后得到含咪唑并[1，2-b]吡唑甲硫醚类化合物6a-6g。

The depositional environment is the main factor for high-sulfur coal formation, and so is the participation of bacteria and algae.

聚煤环境是高硫煤形成的主要控制因素，在成煤作用过程中，细菌和藻类的参与是高硫煤形成的关键所在。

The effects of C/Fe on desulphur rate is obvious different from the influence on content of sulfur in DRI, the mechanics of desulphur of pellet bearing carbon in DR process depends strongly on the exist constitution of sulfur in it.

含碳球团中的硫酸盐硫将残留在DRI中，文章据此提出了临界内配碳比的概念，当内配碳比低于临界值时，提高内配碳可以同时起到加速还原和脱硫的作用，当内配碳比高于临界值时，将会造成DRI含硫超标。

In low basicity, because of the low melting of the slag phase, it is bad for the gas-solid reaction of ferric iron oxide and separating iron from slag The research discovered: Sulfur can be deprived above 90% during direct reduction. The mechanic of desulphurization is gasification desulphur.

研究发现，在直接还原过程中可以脱除90%以上的硫，脱硫主要机理是气化脱硫，内配煤团块中的硫化物和有机硫进入气相，一部分随炉气脱离团块，一部分被配入的CaO吸收。

Namely, only for biobriquette low presence of dialkyl sulphides and aliphatic thiols was registered.

对于生物型煤来说，仅检测到少量二烷基硫醚和脂肪硫醇的存在。

The poisoning effects of alkyl sulfur compounds on the reactivity of isoprene hydrogenation over supported Pd catalyst are more and more serious with the decrease of the molecular mass of alkyl thiols and dialkyl disulfides.

乙硫醇和二甲基二硫醚使Pd／树脂催化剂中毒的机理是，它们分别在催化剂上发生SH和S-S键断裂，并与Pd形成带烷基基团的S-Pd吸附络合物，致使催化剂上异戊二烯选择加氢活性降低。

The studies of radiation chemistry of three main components of garlic oil-diallyl sulfide, diallyl ...

本论文分别研究了大蒜油主要成份二烯丙基一硫、二烯丙基二硫和二烯丙基三硫化物乙醇溶液的辐射化学。

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％。
