| 摘 要： | 针对红松和白松特征相似,容易被冒充的现象,提出了采用光纤液滴分析技术对两者进行树种识别的方法。采用高压反应釜对白松和红松木屑进行了液化,由光纤液滴分析仪实验装置得到了相应的光纤液滴指纹图。比较了两者指纹图的形状,提取了液滴总周期、光纤信号的平均值、光纤信号的波谷值、光纤信号的波峰值等9个特征,结果表明:二者的指纹图在形状上有明显的差异,9个特征值中,3个特征值的相对差异小于10%,1个特征值的相对差异超过了10%,5个特征值的相对差异超过了50%。运用方差分析对两个树种的特征值差异性进行了检验,得出两个树种的特征值差异性显著(P值为0.002 887)。说明光纤液滴分析技术具备识别红松和白松树种的能力。

| Abstract: | The Korean pine and white pine have the similar features,which is easy to be confused,so we put forward the method of identifying the two species based on fiber liquid drop analysis technology.We liquefied the sawdust of Korean pine and white pine with autoclave,and got the corresponding liquid drop fingerprint by the fiber liquid drop analysis.The shape of the two fingerprints had the obvious differences: among ten eigenvalues,the relative difference of three was less than 10％,the relative difference of one is more than 10％,and the relative difference of five is more than 50％by comparing the shapes of two fingerprint and extracting the drop total period,fiber signal average value,optical signal trough value,optical signal peak value and other nine eigenvalues.We used the variance analysis to test the difference of the characteristic values of the two tree species.The difference was significant between the two species(P=0.002887).The technology based on fiber drop analysis has the ability to identify the Korean pine and white pine. |
