采用臭氧氧化、可食膜掩蔽、臭氧氧化+可食膜掩蔽3种方法,清除榴莲果肉表面臭味,并利用电子鼻定量检测除臭效果。将密封榴莲果肉样品的系统开0、8、16个小孔,减小榴莲果肉的裸露面积,使榴莲臭味形成3种质量浓度梯度,电子鼻信号曲线能较快地达到平稳状态,用于建立偏最小二乘(partial least squares,PLS)法分析模型。
Currently technology to utilize laser pulses for the treatment of hard tooth structure is in well underway. Research and development efforts by the Dental Sciences and equipment manufacturers have placed great emphasis on the need to develop accurate methods to characterize and guide the development of this new method of dental treatment. Infinitefocus microscopy is a method of imaging and quantifying microscopic three- dimensional features. This unique optical reconstruction technique is referred to as “Topomicroscopy”. It is ideally suited to the evaluation of laser (and conventional) dental drilling procedures because of its ability to produce geometricallyaccurate, 3D color images and the corresponding volumetric data sets of drilled dental surfaces.
