摘要
根据 Bloch方程的解析解对 DANTE脉冲序列进行计算机模拟 .模拟结果表明 ,脉冲序列首尾两个脉冲对激发频谱边瓣的影响最大 ,将首尾两个脉冲的宽度减小一半 ,可在一定程度上减小激发频谱的边瓣 .通过实验比较了 DANTE脉冲序列与首尾减半 DANTE脉冲序列对溶剂峰的抑制 。
The frequency domain profiles of DANTE pulse sequence are calculated according to the analytical solutions of Bloch equations. The results show that the first and the last pulses of pulse sequence show the biggest effects on the side band. If the widths of the first and the last pulses are reduced to one half, the side band can be suppressed to a great extent. The corresponding experimental results coincide well with the above conclusion.
