化学干扰 meaning in English

chemical interference

The solution background that resulted from the chemical interference , would be the primary factor that effected the sensitivity . especially in the present microfluidic system , the chemical background which was usually inevitable because of the carrier solution , would be eliminated by means of using air as the carrier flow , thus a great signal noise ratio ( snr ) and a great sensitivity could be obtained
在微量分析和超微量分析里，化学干扰产生的溶液背景是影响灵敏度的主要因素，尤其在微流控系统中，载流溶液的背景不可避免，用空气作载流就可以消除背景而获得高信噪比和高灵敏度。
