随着我国国防、科学、近代工业的迅速发展,对航测仪器的需要也越来越迫切。但是,航测仪器在使用和存放过程中,往往会生霉、起雾、长锈。从而影响仪器的精度及成图质量。因此,搞好航测仪器的“三防”(防霉、防雾、防锈)工作,有着重要的现实意义。 With the rapid development of China’s national defense, science and modern industry, the need for aerial survey instruments is also becoming more and more urgent. However, aerial equipment in the use and storage process, often mildew, fog, rust. Thus affecting the accuracy of the instrument and mapping quality. Therefore, it is of great practical significance to do a good job in the “three preventions” (anti-mold, anti-fog and rust-proof) of aerial survey equipment.
