Through emulsion breaking experiments,effects on the break emulsion properties of turbine oil by six emulsifying agents added are discussed.Based upon initial screening experiments and match tests,four break emulsion of additives,such as A,B,E and F,have better performance of emulsion breaking.And the three new binary compound additives(A &B,A &E,and A & F)have synergy,especially the A & E compound with its break emulsion performance is superior to each of their own monomer,not only the numerical value of flash point,viscosity are not changed greatly,but also the total acid number is decreasing after the combined.Finally,the orthogonal experiment results show that the best technological of the A & E compound is 0.10%A+0.030%E(wt%),ten minutes churning,and 50℃.
Objective:To investigate the eating habits of rural residents in high-incidence area of esophageal cancer and their cognition of esophageal caner,and provide service for the prevention of cancer.Methods: Rural stay-at-home residents aged over 20 years were surveyed in 4 towns from Yanting county and Nanbu county,using a self-administrated questionnaire on their eating habits and cognition of esophageal cancer.Results: In recent 1 year,43.8%,72.4%,54.3% residents in high-incidence areas of esophageal cancer ate little amount of sauerkraut,pickle,sour vegetable,respectively.17.9% residents understood or distinctly understood esophageal cancer.17.9% residents understood or distinctly understood the local area was high-incidence area of esophageal cancer.7.1%,19.9%,5.7%,3.0%,1.7% residents understood or distinctly understood the common etiological factors,symptoms,therapeutic measures,preventive measures,intervention measures of esophageal cancer,respectively.Conclusion: The living conditions of rural residents in high-incidence area of esophageal cancer were obviously improved,but the propaganda of anticancer and prevention of esophageal cancer should be strengthened,especially in their cognition of esophageal caner.
