The results of 16S rRNA sequence and phylogenetic analysis show that the strain is the closest relative to Desulfovibrio sp. with 96.0% sequence similarity.

基于16SrDNA序列同源性构建了系统发育树，结果表明此株菌是属于脱硫弧菌属的硫酸盐还原菌，与Desulfovibrio具有96.0%的序列相似性。

One pure strain of the sulfate-reducing bacteria was isolated from a sewage treatment plant in Taiyuan and it was identified as Desulfovibrio desulfuricans by morphological observations, as well as physiological and biochemical measurements.

从太原污水处理厂分离到1株硫酸盐还原菌，对其进行形态学观察及生理生化特征测定，鉴定为脱硫脱硫弧菌。

从太原污水处理厂分离到1株硫酸盐还原菌，对其进行形态学观察及生理生化特征测定，鉴定为脱硫脱硫弧菌。

The strain belongs to Desulfovibrio and differ from the previously describe sulfate-reducing bacteria in its optimum growth temperate , carbon source and other characters .

但与该属已报道的硫酸盐还原菌在碳源利用，最适生长温度，最适盐浓度及其它一些生理特征方面均有不同。

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。

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％。
