Characteristics of Quantitative and Qualitative Research Quantitative research--Findings expressed in numerical form, analyzed by various statistical techniques, e.g. average test scores achieved by two or more groups of people. Qualitative--Studies relying on observations and findings expressed and describe...
Lv [21] conducted an analysis to explore the application of the quantitative research method in Chinese educational empirical research and suggested that the major research institutions usually obtain more prominent results through networking. A consensus has been reached in the academic field that ...
Maillard reaction is an important factor that causes significant differences among the three kinds of high-temperature Daqu, which is also an important source of flavor substances. However, there is a lack of research on the composition differences of Maillard reaction products in the three types ...
The NMR spectra were preprocessed with MestReNova software (V9.0.1, Mestrelab Research, Santiago de Compostela, Galicia, Spain). For all of the1H-NMR spectra, FIDs were multiplied by an exponential function with a 0.3 Hz line-broadening factor to improve the signal-to-noise ratio before Fourie...
. Conclusion: This method is simple, sensitive, accurate and reproducible, and it can realize the quantitative analysis and chemical separation of seven kinds of common alkaloids in Semen Nelumbinis and its products and provide a theoretical method for the simultaneous determination of alkaloids. The...
The same product can be processed with different equipment, and the energy consumption and carbon emission values of equipment production processes are quite different from each other. In the actual process, the equipment selection usually relies on qualitative analysis rather than quantitative calculation...
