- In ion chromatography experiment, how to eliminate the F(superscript -) negative peak was a very difficult problem. 摘要在离子色谱分析实验中，如何消除氟离子负峰是一个棘手的难题。
- Mg~(2+), which is required for carboxylation of PEP, induced a spectrum with a wide positive absorption band whose maximum is located at 275nm, and a negative peak at 237nm. Mg~(2+)产生的差光谱在275nm附近为正的阔峰,在237nm处为一负峰。
- negative peak clipping distortion 负削峰失真
- Circuit operation is as follows: negative peaks in excess of -8.25V cause D1 and D2 to conduct, charging C4.The charge stored in C4 provides bias to Q1, which determines amplifier gain. 电路原理如下：超出-8.;25V的负电平使D1和D2导通，给C4充电，C4储存的电荷为Q1提供偏置，从而控制放大器的增益。
