Please to translate this paragraph."...the range of 8-to-1 ...

Please help me to translate this paragraph:
“In common commercial practice, an endothermic or purified exothermic gas is used as the carrier, and it is enriched with one of the hydrocarbon gases. The ratio of carrier gas to hydrocarbon gas varies widely in industry but is usually in the range of 8-to -1 to 30-to-1. the ratio used depends on the types of carrier and hydrocarbon gases, the furnace size and condition, the amount of circulation, and the surface area of the workpieces.”

在一般的工业实践中,以吸热式气氛或净化后的吸热式气氛作为载气,富化气使用碳氢化合物中的一种。在工业上,载气和富化气的比例在很大范围内变化,通常在8:1到30:1之间,这时因为该比例取决于载气、富化气、炉子尺寸和工况、气体循环和工件表面积。
