Determining the attainability domain of aeroassisted orbital plane change, i.e. the inclination and the longitude of the ascending node, is a very important problem.
An equalarea pseudo cylindrical projection gather is constructed, in which the longitudes are hyperbola being symmetrical to the central meridian and the latitudes are parallel lines.
It uses the high strength helenienne,weaving the grid gray cloth after the warp knitting of longitude and latitude direction,and through overlaying and processingprocesses to making geogrid.
That means the birch from high longitude and latitude areas will have lower content of the ash, extraction and lignin, higher content of the holocellulose and pentosan in the wood.
