The pretreatment conditions of sample, chemical interference, detection limit and characteristic concentration were studied.

对样品处理条件、化学干扰、检出限及特征浓度进行了考察。

Laboratory experiments show that when chemical interference with relation to the concentration presents itself, it has an effect on the linearity of the standard curve.

实验表明，当这类干扰存在时，将影响工作曲线的线性，因而影响到标准加入法测定结果的可靠性。

The pretreatment condition of sample, chemical interference, identity of viscosity for test solution and its blank solution, background absorption interference and detection limit were all studied.

对样品处理条件、化学干扰、试液粘度与空白溶液粘度的一致性、背景吸收干扰及检出限进行了考察。

And I also request the United Nations to give guarantees for our own personal integrity, as well as the lives of the people who are being attacked with chemical gases, with electronic interference at this diplomatic site of the sister Republic of Brazil."
