查询词典 distilled spirit

When the cyanide is determined by isonicotinic acidpyrazalon method, the ethyl benzoate is distilled and goes into NaOH absorption liquid with cyanide in the process of predistillation, because its boiling point is low.

在用异烟酸吡唑啉酮法对其进行氰化物测定时，由于油酯类的沸点较低，在预蒸馏过程中被蒸出和氰化物一起进入NaOH吸收液

The wastewater from gum benzion production contains benzaldehyde, cyanide, gum benzoin and ethyl benzoate. When the cyanide is determined by isonicotinic acidpyrazalon method, the ethyl benzoate is distilled and goes into NaOH absorption liquid with cyanide in the process of predistillation, because its boiling point is low. Thus the absorption liquid produces a great deal of foam and feculence.

摘要］有机化工产品安息香生产废水中含有苯甲醛、氰化物、安息香和苯甲酸乙酯，在用异烟酸吡唑啉酮法对其进行氰化物测定时，由于油酯类的沸点较低，在预蒸馏过程中被蒸出和氰化物一起进入NaOH吸收液，使得吸收液产生大量泡沫和沉淀，严重干扰后续比色测定。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
