Abstract: The disclosure relates to the technical field of food processing, particularly to a grilling method for controlling the content of polycyclic aromatic hydrocarbons in charcoal grilled meat. The grilling method comprises: Step 1, dispensing to-be-grilled meat into boxes with sealing covers, and adding edible oil into the boxes, wherein a ratio of edible oil to the weight of meat is 25˜50 mL/1000 g, and sealing the covers; Step 2, carrying out plasma treatment on the meat sealed in Step 1; and Step 3: placing the meat treated using plasma onto a grill and grilling. The grilling method for controlling the content of polycyclic aromatic hydrocarbons in charcoal grilled meat is simple, convenient, and easy to operate; it is not needed adding unessential food additives, thereby significantly reducing the content of polycyclic aromatic hydrocarbons in meat products, saving cost and improving safety while remaining the flavor of food itself.

Abstract: The invention provides novel polymer compositions and methods for preparing such compositions. The invention also provides methods for polymerizing various unsaturated monomers, including naturally occurring or plant biomass-derived renewable acrylic monomers. The monomers can be rapidly polymerized using various organic catalysts or organometallic catalysts, as described herein. In one embodiment, nearly perfectly isotactic polymers (mmmm>99%) can be prepared using a C2-symmetric zirconocenium catalyst.

Abstract: A key device and electronic apparatus containing the key device. The key device comprises a housing and key structure, a hollow accommodating space in the housing. The key structure comprising: a key body, at least part of the key body being accommodated in the hollow accommodating space; a lateral contacting structure within the hollow accommodating space and comprising a contacting portion provided at the outer side of the key body, and when being pressed, the lateral contacting structure being squeezed by the key body, so that the contacting portion is in contact with a flexible printed circuit board; and a flexible printed circuit board within the hollow accommodating space at the outer side of the contacting portion for inducting the lateral contact of the contacting portion. Since lateral contact is made with the flexible printed circuit board, the key may be transparent when the key body is transparent.

Abstract: The embodiments of the present invention provide a SIM card slot having a fool-proof function and electronic apparatus containing the SIM card slot. The SIM card slot comprises: an accommodating space for accommodating the SIM card; and a cover, which may be of metal, positioned above the accommodating space; wherein a recessed zone is arranged in the cover, the recessed zone constituting a stopping sheet for blocking the insertion of the bevel edge of the SIM card. The wrong insertion of the SIM card of the electronic apparatus, such as a mobile terminal, may be prevented by the SIM card slot having a fool-proof function and electronic apparatus containing the SIM card slot of the present invention. Upon correct insertion the SIM card edge will cause the stopping sheet to be lifted, but with incorrect insertion the stopping sheet will engage the card bevel edge to block further insertion.
