Mechanical Design and Research on Process of Air Suction Drawing System of Spunbonded Nonwoven

The design guideline for the air suction drawing system with auxiliary air was analyzed, a spunbonding nonwoven system named PADHL1 - 3200 was designed and polypropylene （PP） spunbonded nonwoven fabrics with excellent properties were achieved after many trial runs. On the other hand, the suction air velocity （VA） was calculated and the influence of VA on the bonding strengh of PP nonwoven fabrics was Studied as well. It was found that VA is 1.5 - 2.5 times of the spinning velocity. With the increase of VA, PP fibers become finer and the bonding strength of PP nonwoven fabrics increases as well.     

Long term monitoring of urban subsidence by Permanent Scatterer DInSAR

When using differential SAR interferometry (DInSAR) to monitor the surface deformation over a long time scale, it is often strongly affected by the spatial and temporal decorrelations and atmospheric dishomogeneities. The recently developed Permanent Scatterers (PS) technique proposed by Fertti et al. can overcome these difficulties by interpreting time-series of interferometric phase only at coherent point scatterers. In this study, we apply this PS technique using 25 ERS-1/2 scenes from 1992 to 2000 to monitor the subsidence in Suzhou. By using the linear deformation model, the deformation map in Suzhou urban area over the eight years is obtained. And the calculated results are in good agreement with the measurements of leveling.
