摘　　要：基于室内试验,筛选出十六醇+正丙醇和十八醇+正丙醇复配两种非均相水分蒸发抑制剂,并开展小区试验研究,结果表明:十六醇+正丙醇复配非均相阻蒸发制剂随着用量的增加,其阻蒸发效率趋于稳定;十六醇+正丙醇复配单分子膜最佳铺膜计量值为3.50mL/m2;十八醇+正丙醇复配单分子膜随着用量增加,阻蒸发效率也趋于稳定值,十八醇+正丙醇复配单分子膜最佳铺膜计量值为3.83 mL/m2。十八醇+正丙醇非均相阻蒸发抑制剂的平均抑制率34.5%,十六醇+正丙醇非均相阻蒸发抑制剂的平均抑制率30.4%,十八醇+正丙醇阻蒸发效果要明显优于十六醇+正丙醇,与室内试验结果一致。According to the results of indoor tests, Cetyl alcohol mixed with n-propyl alcohol and Octadecanol mixed with n-propyl al- cohol are selected as the compound non-homogeneous preventing evaporation preparation, and small experimental studies are carried out. The results show that with the amount increase in Cetyl alcohol mixed with n-propyl alcohol compound non-homogeneous pre- venting evaporation preparation, its preventing evaporation efficiency is stabilizing. The conclusion is that best spreading films meas- urement value of Cetyl alcohol mixed with n-propyl alcohol compound monomolecular films is 3. 50 mL/m^2. With the amount in- crease in Octadecanol mixed with n-propyl alcohol compound non homogeneous preventing evaporation preparation, its preventing e- vaporation efficiency is stabilizing, the conclusion is that the best spreading films measurement value of Octadecanol mixed with n- propyl alcohol compound monomolecular films is 3.83 mL/m2. The average inhibition rate of Octadecanol mixed with n-propyl alco- hol compound monomolecular films 34. 5%. The average inhibition rate of Cetyl alcohol mixed with n-propyl alcohol compound mon- omolecular films 30.40ctadecanol q- n-propanol evaporation barrier effect is much better than cetyl alcohol q- n-propanol, consistent with laboratory test results.
