Abstract: The present invention relates to a method for preparing a polyether amine catalyst, and polyether amine. A polyether amine catalyst is a supported metal catalyst; ?-Al2O3 is used as a carrier; basic cupric carbonate, basic nickel carbonate and basic cobalt carbonate are used as precursors of supported metals; and the polyether amine catalyst is prepared by performing twice adsorption roasting and once reduction by means of an equivalent-volumetic impregnation method. Easier decomposition is achieved by using basic carbonate, and only water and carbon dioxide are generated, such that processes and costs for treating waste gases can be saved. By using the polyether amine catalyst to prepare polyether amine, a conversion rate and primary amine selectivity can be improved, and the color of products can be reduced. Therefore, the obtained polyether amine can have higher activity and wider application.

Abstract: A method for evaluating the possibility of a cigarette burning cone to fall off is disclosed. The method uses a manipulator simulation device to simulate the smoking of a cigarette, and measures the maximum deviation of the cigarette burning cone, and then uses angle summing and averaging to add the maximum deviations of the cigarette burning cones measured for multiple cigarettes and obtain an average value, and then evaluates the possibility of the cigarette burning cone to fall by the average value of the maximum deviations of the cigarette burning cone. The method is new, and compared with an existing method using state information of the cigarette burning cone “falling” and “not falling,” the method can more accurately, directly and timely reflect the state of the cigarette burning cone.

Abstract: UV light may be directed through a patterned window to cause selective UV exposure of certain areas of a substrate. A stress-tunable film deposited on the substrate may undergo localized stress changes from selective UV exposure. Localized stress changes in the stress-tunable film may mitigate wafer bowing in the substrate. The patterned window may be designed with UV-transparent regions and UV-non-transparent regions to facilitate targeted UV exposure of the stress-tunable film. In some implementations, the patterned window may include a metal coating, a ceramic cover, or a metal cover for selective UV exposure. In some implementations, the patterned window may further include transition regions that permit partial transmission of UV light to limit stress changes in corresponding areas of the stress-tunable film.
