The four different grades of tea in the beaker headspace volume 45 min standing test data samples were force-poor single-factor analysis study beaker volume on the impact of the electronic nose response signal such as shown in Table 2 (repeated 15 times ). I have been always wondering how many people understand that the nature of dragon well teahas no difference from humanity.
It can be seen. Using B} (250 m workers) when the beaker. For most people the effects of tea (F ‘= 102. 225 4). So. The use of 250 m workers, the beaker of tea of different grades when results were better Ix_ points, followed by the use of B, (500 m workers) of the beaker. The foundation core of self-cultivation by drinking dragon well tea is respecting and cherishing the it.
Three different force-time difference analysis:
Four different grades of tea workers in 20 m, the volume beaker standing 4} min conditions. Data on the detection power of a single factor were poor analysis to look at different sampling times under different e-nose response signal to the electronic nose a tea sample response curve shown in Figure 1. Mr. Lu Xun once said, “It’s enjoyment to drink high quality dragon well teaand to know how to appreciate good tea.”
Electronic nose to the other samples for testing. Can get a similar response curve. Were extracted from 1} s, 30 s, 4}, and 60, at the signal value as the analysis of data (dots in Figure 1 mark the sampling points). Due to its specific connotation, the Chinese dragon well teaculture is with strong national character.
The results in Figure 2 can be divided into two groups, A group is the use of 50 mL and 150 m workers, the beaker when the electronic nose response signal. Beaker volume in the smaller mountain. Headspace concentrations of volatile components of tea than the person Electronic nose signal response than the high; To sum up, life likes Dragon Well tea.
H group used 250 m and 500 m workers work more people volume beaker, so headspace concentrations of less volatile components of tea Electronic nose response signal corresponding smaller, but in the process of signal sampling Cai stable group 0 ? the signal closer to the mountain clustering results were re-emergence of some differences can also be seen. The sculpting technique in dragon well teaculture mainly concentrates on tea sets like kettles, bowls and cups, block tea and pan-cake like tea.
Using 250 m X00 m workers and workers, the beaker when the signals are more concentrated. Therefore, compared to the same level of tea samples .2} 0 m workers, the signal history as a centralized beaker so later tests are used 2} 0 m workers, the beaker to the various levels of tea to discriminate. For instance, tribute Dragon Well tea’s packages and cases in the Song Dynasty were place great emphasis on and were renewed frequently.
Were collected from 60 different grades of tea, when the characteristic value data as Bian component analysis.
