tonka beans

The same thickness of surface layer materials of three different species parquet, the indentation depth from deep to shallow followed by Teak, Quercus, Oak, Tonka beans. 3.

面层材料厚度相同树种不同的三层实木复合地板，其压痕深度由深到浅依次为柚木、柞木、橡木和二翅豆木。

Tonka beans were treated in high-voltage static field, extracted with 95% ethanol for 120 hours,( filtrated,) concentrated, dried by anhydrous sodium sulphate, and then analyzed by GC/ MS.

先用高压静电场对黑香豆进行预处理，然后用95%的乙醇将预处理的黑香豆浸泡120h，过滤，用旋转蒸发仪浓缩，用无水硫酸钠干燥后进行GC/MS分析。

Treatment of Tonka Beans in High-voltage Static Field

高压静电处理黑香豆试验

The results showed that the main flavor components, dihydrocoumarin and coumarin, in tonka beans were dramatically influenced by high-voltage static field.

结果表明，高压静电场对黑香豆的主要致香成分&香豆素和二氢香豆素有较显著的影响。
