A high purity aqueous solution of hydroxylamine product is prepared by treating an aqueous solution of hydroxylammonium salt with a base like ammonia at low temperatures. A novel process can be carried out by separating the ammonium salt side product from hydroxylamine with a low temperature filtration and a resin-exchange process. The concentration of the hydroxylamine product is further improved by a safe distillation process that produces a high purity and high concentration hydroxylamine product with reduced risks of explosion.

A system for multilevel simulation of an animation cloth is provided. The system includes a multilevel area generation module, a curvature calculation module, a curvature comparison module, and a dynamic simulation module. The multilevel area generation module divides a plurality of grid units of the animation cloth into a plurality of level sub-areas based on a multilevel technique, wherein each of the level sub-areas is generated by dividing an upper level sub-area. The curvature calculation module calculates the curvatures of the level sub-areas according to the plane vectors of the grid units in a frame. The curvature comparison module compares the curvatures of the level sub-areas with a flatness threshold. The dynamic simulation module calculates the plane vector of each grid unit in a next frame through different method according to the comparison result of the curvature comparison module.
