The invention relates to a preparation method for an intelligent temperature-variable and immersion-proof shell fabric and a product thereof. The preparation method comprises the following steps: 1. temperature-variable copolymer of N-tert-butyl-acrylamide and acrylamide is obtained through the composition with a to b as the mole ratio of incoming stocks; wherein, the a lies between 60 and 40, and the b lies between 40 and 60; 2. a coating layer liquid is prepared according to the following concentration formulation by mass: 8 to 15 percent of the copolymer, 2.0 to 5.0 percent of a crosslinking agent that is 1,2,3,4-butane tetrabasic carboxylic acid and 0.5 to 2.5 percent of a catalyst that is sodium hypophosphite; 3.the coating layer liquid is used for coating a preprocessed fabric; 4. the immersion-proof shell fabric can be obtained through post processing. The product is produced by adopting the preparation method of the intelligent temperature-variable and immersion-proof fabric of the invention.

New methods for determining the volumetric composition and saturation of methane and NGLs (natural gas liquids: ethane, propane, butane, and pentane) in a petroleum reservoir combining NMR (nuclear magnetic resonance) logging and NMR core analysis and for determining the mean pore-size and tortuosity of the light hydrocarbon-filled porosity in a petroleum reservoir using NMR core analysis.

The invention relates to the field of petrochemical engineering, and discloses a silicon carbide micro-channel alkylation reactor and an application method thereof. A liquid acid circulating pipe (4),a raw material feed inlet (5), a gas phase extraction port (6) and a liquid phase extraction port (7) are respectively arranged on a reactor shell; a micro-channel reaction module and a defoaming separation component (3) are sequentially perpendicularly arranged in the shell from top to bottom; the raw material feed inlet (5) is formed in the top part of the shell; an upper end port of the liquidacid circulating pipe (4) is communicated with an inner cavity of the shell through a liquid acid feed inlet in the top part of the shell; the gas phase extraction port (6) is arranged on the lower part of the micro-channel reaction module. According to the silicon carbide micro-channel alkylation reactor and the application method thereof provided by the invention, iso-butane and olefin are adopted as raw materials, liquid acid is adopted as a catalyst, and a target product alkylate oil is obtained through alkylation reaction. The silicon carbide micro-channel alkylation reactor provided bythe invention effectively solves the problem that an alkylation reactor is nonuniform in temperature distribution, and has the characteristics of good raw material distribution, easiness in temperature control, high product quality and the like.

A smoking device which permits combustion and inhalation of smoking material without also inhaling gases from a source of combustion such as lighter. The smoking device has a main body with a lower end adapted to connect to an overall smoking system. A lower portion of the main body defines internal flow channels, while an upper portion defines a smoking chamber therein. A burn plate or disc is clamped against an inner ledge in the lower end of the smoking chamber which is enclosed by a lid having an air inlet. The smoking chamber may house a manifold member which clamps the burn plate against an inner ledge. A user places smoking material on the burn plate and closes the smoking chamber with the lid. While applying a lighter flame directed into the lateral throughbore to the underside of the burn plate, the user applies suction to the lower inhalation passageway which pulls air in through the air inlet in the lid. Combustion of the smoking material creates smoke which is ported through the smoking device to the user without pulling in any of the gases from the lighter flame.
