由于空气中氧的阻聚效应，而经常引起室温固化不饱和聚酯树脂表面发粘。
The cure-inhibition effect of the atmospheric oxygen usually causes the surface stick of the cold-cured unsaturated polyester resin.
用二环戊二烯，顺丁烯二酸和乙二醇合成不饱和聚酯，这种不饱和聚酯既可浇铸，也可以在空气中固化。
An unsaturated polyester resin was synthesized from dicyclopentadiene maleic acid and ethylene glycol. this resin can be moulded by casting and also can be hardened in air.

如果温度一定，空气中的水蒸汽含量与不饱和状态下最大水蒸气含量就有相对关系。
The amount of water vapor in the air relative to how much water vapor the air can "hold" before saturation occurs at a given temperature.
