查询词典 sulfur grundum

Based on the study of rock textures and structures, and stable isotopes of dolomite and S isotope of barite interlayers within the cap dolomite outcropped in the Miaohe area in the Three Gorge, it is testified that the stable isotopes show a strong negative excursion, and the isotopes of sulfur show a significant positive excursion, which is similar to the reported data of authigenic barites formed in a modern seafloor gas hydrate environment. Therefore, it can be concluded that the cap dolomite was most likely formed in a special environment under which a huge gas hydrate dissociated with the breakup of "Snow Earth" in later Neoproterozoic.

通过对湖北三峡庙河地区出露的&盖帽&白云岩的野外地质构造、碳－氧稳定同位素和重晶石夹层的硫稳定同位素特征的研究，发现除了明显的碳稳定同位素的负偏移之外，重晶石的硫同位素值表现出明显的正偏移，其数值可与现代海底甲烷喷气孔附近的自生重晶石矿物的同位素组成相对比，进而认为&盖帽&白云岩的成因是末元古代&雪球&事件之后天然气水合物的释放与全球环境突变背景下的沉积产物。

But the models also suggest that the scheme could go too far: Adding excess sulfur could increase ice in Antarctica,"overcompensating" for warming, says Rasch, which could affect ecosystems and the global ocean-atmosphere system in a myriad of ways that scientists haven't studied.

拉什说：&但是，模型实验显示计划的最终效果可能事与愿违，南极冰层会因为大气层中注入过多的硫磺而增厚，使全球的生态系统和海洋大气系统受到影响，产生这些影响的方式是多种多样的，有可能完全超出科学家们的研究范围，从而造成比全球变暖更严重的后果，让我们得不偿失。&

The δ^34S values of ore minerals vary slightly from -3.1‰ to +0.7‰ with an average value of -1.1‰ and the δ^34S values of the ore-bearing porphyries are -1.4‰ and -1.5‰, indicating that sulfur is mainly derived from the magma of porphyry.

雪鸡坪铜矿S，Pb同位素组成共同指示成矿物质主要来自于深部岩浆，这种岩浆可能主要起源于俯冲洋壳板片的部分熔融并受到少量地壳物质的混染。

Cut down cost in changing a project for the energy saving,the gas making use of a sulfur dioxide to change is that the cold stove gas preheats , reduces at the same time to change the air temperature degree , reclaim the quantity of heat changing an implement.

转化工程中为了节约能源，减少成本，利用二氧化硫转化气为冷炉气预热，同时降低转化气温度，回收转化器的热量。

Since H〓S and SO〓 adsorbed on TiO〓 could react with each other and TiO〓 is the medium of their electron transfer, thus SO〓 could not be adsorbed quite strong on the active site of TiO〓, which makes it more resistant to sulfating and increase the stability of catalyst. Finally, the model and mechanism of the reduction of SO〓 by NH〓 to elemental sulfur is advanced as follows: on the sulfide catalyst, ammonia is decomposed to N〓 and H〓, and H〓 reacts with SO〓 to form the intermedium of H〓S; then H〓S and SO〓 react as Claus reaction on TiO〓 catalyst.

反应系统中过量水蒸气的存在使催化剂表面某些活性位被水蒸气抑制使活性和选择性有较大幅度降低，但这种影响是可逆的，不会造成催化剂永久性中毒；另外当单质硫和水蒸气同时存在时，在〓催化剂上能够生成硫化氢和二氧化硫，而且由于硫化氢和二氧化硫化学吸附能力不同而导致它们的脱附顺序不同，硫化氢的生成温度总是低于二氧化硫的生成温度，说明过量水蒸气的存在会导致氧化物催化剂上逆克劳斯反应的发生；而在硫化物催化剂上几乎没有硫化氢和二氧化硫生成，说明硫化物催化剂能够抑制逆克劳斯反应的发生。
