Applicant's summary and conclusion

Conclusions:
The result showed that the vapour pressure of the test item was 0.01 kPa (20.0 degree centigrade), 0.11 kPa (40 degree centigrade) and 0.22 kPa (50 degree centigrade). According to the fitting regression curve, it was calculated that vapor pressure of the test item was 0.02 kPa at 25 degree centigrade.
