目前鉴定中国漆的方法仍是古老的经验的定性方法。我们希望能用更先进的科学方法,以便达到定量分析阶段。因此,在结构研究的基础上,提出了一个鉴定中国漆质量优劣的新的测试方法。用小量生漆溶于CCl_4中,过滤除去不溶物,加TMS作内标,得样品。从核磁共振频率为200MHz的谱图积分曲线,我们算出了各类质子数的相对比值。从结构式 Currently, the method of identifying Chinese lacquer is still a qualitative method of ancient experience. We hope we can use more advanced scientific methods in order to reach the quantitative analysis stage. Therefore, on the basis of the structural study, a new test method to identify the quality of Chinese lacquer is proposed. A small amount of raw paint dissolved in CCl_4, insoluble matter removed by filtration, plus TMS as internal standard, have samples. From the spectrogram integral curve with a nuclear magnetic resonance frequency of 200 MHz, we calculated the relative ratios of the various proton numbers. From the structural type
