摘　　要：通过测定两种具有D—π—D结构的有机分子的吸收谱,并根据三能级模型对其跃迁偶极矩进行了计算.并从结构-性质的关系对其高阶非线性光学效应进行了预测,认为这两种分子将会具有较大双光子吸收截面.This paper introduces the method through which waveform if produced and displayed based on LabVIEW. By utilizing LabVIEW and corresponding fictitious instrument, waveform can be produced and displayed easily and swiftly. This method has offered a shortcut for the study and practice of testing the technologies in the field of science and engineering.
