Abstract: Embodiments of the present invention relate to the field of communications methods and technologies, and in particular, to a transmission method and apparatus. The transmission method includes: generating, by a first device, a sequence based on one or more transmission parameters, where the one or more transmission parameters include at least one of the following: a time domain resource type, transmission waveform indication information, subcarrier spacing indication information, device type information, service type indication information, multiple-input multiple-output MIMO parameter information, duplex mode indication information, control channel format indication information, and transmission carrier indication information; generating to-be-transmitted information by using the sequence; and sending the to-be-transmitted information. According to the transmission method and apparatus in the embodiments of the present invention, a new transmission error check mechanism is provided.

Abstract: Provided are a wireless power supply system applied to a refrigerating device, a drawer assembly and the refrigerating device. The wireless power supply system comprises a control module, a display control module, a wireless communication module, a wireless power supply module, a battery module, and a detection module. The wireless power supply module comprises a wireless power supply receiving module and a wireless power supply transmitting module; when the wireless power supply receiving module gets close to the wireless power supply transmitting module so as to achieve electrical connection, the display control module is switched on; when the detection module detects that the wireless power supply receiving module gets away from the wireless power supply transmitting module so as to achieve disconnection, the battery module is discharged to switch on the display control module so as to continuously supply power to the display control module.

Abstract: A process for the production of a hydrocarbon which comprises contacting, in a reactor, methanol and/or dimethyl ether with a catalyst comprising a metal halide, such as a zinc halide, in which the methanol and/or dimethyl ether is contacted with the catalyst in the presence of at least one phosphorus compound having at least one P—H bond.

Abstract: The present invention relates to a new kind of heavy metal chelating agents and a preparation process and uses thereof. The said heavy metal chelating agents are expressed in &agr;-[D(+)glucose-1-yl-amino]-&bgr;3-mercapto-(S)-propanoic acid (abbreviated to NGP,I) and/or N,N′-di[D(+)glucose-1-yl]-L-cystine (abbreviated to NGCD,II). In the process of preparation, glucose and cysteine are reacted with a base, with a reducing agent, and the obtained products are acidified to give NGP,I, which can be used in and/or as drugs, health foods and food additives for accelerating the excretion of heavy metals including Pb, Cd, Hg, Al, Sb, As, etc. The structural feature of the compounds of the present invention is that they contain glucose and cysteirie in their molecules.
