Abstract: A method for testing burning performance of a dark-colored cigarette using a dark-colored cigarette paper is provided. The dark-colored cigarette paper has a grayscale less than 255. The method includes: simulating, by a robotic arm, a cigarette smoking process and environment; acquiring, by a full-vision camera system, an image of a burn line and ash column region of the dark-colored cigarette; and analyzing a burning performance indicator of the dark-colored cigarette according to coordinate information of the burn line and ash column region. The method is based on a surface reflection characteristic of the dark-colored cigarette paper and a principle of optical reflection to light and highlight an edge of the dark-colored cigarette sample by a light source at a certain angle from a side. In this way, the method forms a chromatic aberration to localize the dark-colored cigarette sample, thereby testing the burning performance of the dark-colored cigarette sample.

Abstract: Embodiments of this application disclose a noise cancellation apparatus and method. The noise cancellation apparatus includes a main control unit and a noise cancellation processing circuit. The main control unit determines a noise cancellation parameter based on a noise cancellation level index or a feature value for determining a matching degree between a headset and an ear canal of a user. The noise cancellation processing unit obtains an inverse phase noise of an ambient noise based on the noise cancellation parameter. After the inverse phase noise is mixed with a played downlink audio signal, the ambient noise can be canceled. In addition, because the noise cancellation parameter is determined from a preset noise cancellation parameter library based on the received or autonomously determined noise cancellation level index, instead of being uniformly configured, a noise cancellation level can be flexibly adjusted, thereby improving a noise cancellation effect and user experience.

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-volumetric 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.
