摘　　要：内添加型流滴-消雾膜在温室大棚上的应用已经是很成熟的技术。近年来具有不产生雾气这一突出优点的新兴外涂流滴膜对内添加型棚膜产生了越来越大的冲击。为进一步改进内添加型棚膜消雾功能,在众人多年研究的基础上,笔者试图归纳和建立内添加型棚膜产雾和消雾的物化模型,同时列举了大田实验数据加以佐证。最后对进一步改进棚膜的消雾能力提出了自己的意见和建议。The application of anti-dropping agent and anti-fogging agent as additives used in greenhouse film has already been a mature technology. Recently the rising anti-dropping film coated outsides with no-fog applied in greenhouse has more and more effects on the greenhouse film with additives such as anti-dropping agent and anti-fogging agent. For improving the anti-fogging function of greenhouse film, the anti-dropping agent and anti-fogging agent were used in greenhouse film based on the research of others for many years. The physical and chemical models about the fog producing and disappearing in greenhouse when additives were used in films were founded based on the analysis of data, and lots of experiment data from farmland were listed to prove the model. Finaly, the proposal and suggestion about how to improve the anti-fogging performance were put forward.
