本文分别用双共振选择性自旋去耦、双共振自旋搔动方法判定异植物醇中ABX体系耦合常数的相对符号为同号。
The relative signs of coupling constants in ABX system for isophytol were determined using two methods of double resonance: selective spin decoupling and spin tickling methods.
每个校正位试验的作用是如果(具有任何符号的)大噪声事件已对在前位试验做出了错误的判定，则使得ADC减少DAC误差。
The effect of each correction bit trial is to allow the ADC to reduce the DAC error if a large noise event (of either sign) has caused a wrong decision to be made on a previous bit trial.
