Abstract: Method for making a carbon molecular sieves described herein may include applying an adhesive to exterior surfaces of polymeric hollow fibers at a first end of a plurality of polymeric hollow fibers, wherein the polymeric hollow fibers include polyimide, polyvinylidene chloride, or a combination thereof, and wherein the adhesive includes at least 75 wt. % polyimide, polyvinylidene chloride, or a combination thereof, based on the total weight of the adhesive; curing the adhesive on the exterior surfaces of the polymeric hollow fibers to form a carbon molecular sieve precursor; and pyrolyzing the carbon molecular sieve precursor to form a carbon molecular sieve, wherein the carbon molecular sieve includes a plurality of carbon hollow fibers and a carbonaceous adhesive residue on a first end of the plurality of carbon fibers.

Abstract: The invention relates to a method for extracting ground attribute data in interferometry synthetic aperture radar data, and aims at providing a method for extracting ground attribute data in PS data. The method comprises the following steps that ground geographic data are led; ground boundary data are contracted inwards by Tx in the east-west direction, and are contracted inwards by Ty in the south-north direction, and a new ground boundary is determined again; whether each PS point falls into the new ground boundary or not is judged, and if yes, the data are extracted; if not, the data are removed; a first data set after extraction is obtained; whether the gray value of a PS point image in the first data set is between Vmin and Vmax or not is judged, and if yes, the data are further extracted; if not, the data are removed. The ground attribute data are extracted through the method, so that the accuracy of PS points is 95.1 percent.
