Mechanism Research Upon Relationship Between Molecular Condensation and Sensitive Surface Temperature

Molecular condensation contamination from outgassing behavior of non-metal materials of spacecraft will cause some problems. For the optical and sensitive surfaces in lower temperature state the problem is especially serious and dangerous because the condensation quantity increases as the surface temperature decreases. To look for the mechanism upon the relationship between molecular condensation and sensitive surface temperature, tests and researches are being taken and more than 2000 data have been obtained. The analysis on the data shows that the relationship between molecular condensation and sensitive surface temperature observes exponential law. This result is important and possesses reference value.
