查询词典 sulfide

Armed with this information and further analyses, Rumble, lead author Bekker, and colleagues propose the following scenario today in Science . Early in Earth's history, volcanic eruptions spewed massive amounts of sulfur dioxide into the atmosphere, where UV sunlight broke down the gas and created the odd sulfur isotope ratios. The sulfur descended with the rain and accumulated into sedimentary beds on the sea floor. Once there, superheated water from geothermal vents at various locations on the sea floor cooked the sulfur into sulfide. Finally, nickel-bearing magma welled up from Earth's mantle, combining with the sulfide to form nickel sulfide and encasing the compound inside volcanic rock called komatiite.

凭借这份资料和进一步的分析，朗布尔、研究论文的第一作者贝克及同事们今天在《科学》杂志上提出了如下的推测：在地球早期的历史上，火山爆发将大量的二氧化硫气体喷射到空中，太阳的紫外线将其分解，产生了奇特的硫同位素比值，这种硫随雨降下，积存于海底沉积层中；一旦到达海底，海底各处的地热出口所产生的温度过高的水把硫加热成硫化物；最终含有镍的岩浆从地幔中涌出，跟硫化物结合形成硫化镍，并将硫化镍包裹在一种叫做"科马提岩"的火山岩中。

In the middle of 90's, it has been found that hydrogen sulfide (H2S) is one of the metabolite of aminothiopropionic acid, which might regulate the function of nervous system, especially hippocamp, and might regulation the tension of digestive tube and vascular, which has the similar biological function with NO and CO. Recently, major concern has emerged that H2S might be a novel endogenous agent during the patho-physiological reactions during endotoxic shock. Until now, the role of H2S playing in endotoxic shock is still quite confusing.

九十年代中叶，人们发现在体内半胱氨酸代谢过程中生成小分子气体硫化氢(hydrogen sulfide，H2S)，对神经系统特别是海马功能具有调节作用，且可以调节消化道和血管平滑肌张力，其生物学作用类似NO和CO.H2S作为内毒素休克时一系列病理生理反应中的一种新的内源性介质，已开始受到人们的重视。
