In this paper, the Changchun city was taken as the study area. The data about 10 years on dustfall were collected, the change tendency of dustfall was disclosed. Dustfall samples from October 2005 to February 2006 and samples of pollution sources were collected also. The samples were measured and analyzed by particle size analyzer and ICP-AES. EF and CMB receptor model is used to make source apportiontment of the dustfall.

In order to achieve the setting up angle should be monitored and debugged, a new approach is brought up. With the CCD receiving the focusing spot of parabolic mirror, while rotating the parabolic mirror, collecting the focusing spot location information, the eccentric angle between the optical axis and the structural central axis could be found. System principle and design have been studied.The experimental results meet the need to test and monitor to the setting up angle of the discal parabolic mirror.
