谁能帮我翻译这两句专业英语啊
Two simple methods for sulfite determination in food products were proposed. The modified para-rosaniline (PRA)-formaldehyde method showed a much broader linear range (0.05–5.0 mg l1 as SO2) than the commonly used procedure for the sulfur dioxide detection in the atmosphere (0.05–1.0 mg l1 as SO2). By using a standard reference color card, this method only needed 5 min to complete a test. 展开全部∨ 2 回答 · 3 关注共2个回答

是指该方法用于食品中检测的线性范围比该方法用于测量空气中二氧化硫的线性范围宽

两个用于测定食品中二氧化硫的简单测定方法已被提出。改进的盐酸副玫瑰苯胺—甲醛法，与测量大气中的二氧化硫方法比较测量范围有了提高。该方法的测量范围是(0.05–5.0 mg l1 以 SO2计) ，而大气中的方法为(0.05–1.0 mg l1 以 SO2计)。 该方法使用标准参考色卡，完成一个样品的测量只需5分钟。文中提及的东西怪怪的，一会食品，一会大气？
