    摘要: A method, an apparatus, and a system for transmitting information bits, where the method for transmitting information bits includes: dividing the information bits to be transmitted into at least two groups; encoding the information bits to be transmitted in each group; modulating the coded bits obtained by the encoding to obtain modulation symbols, in which each modulation symbol is obtained by using the modulation of the coded bits in the same group; and mapping and transmitting the modulation symbols. In this way, the receiving end easily reduces the algorithm complexity, thereby ensuring the performance of the receiving end.

    摘要: The disclosure discloses a method, an apparatus and a system for transmitting multimedia data by bluetooth and real-time playing, wherein the method includes: a bluetooth apparatus at a transmitting terminal encodes multimedia files to be transmitted, and converts them into stream media files; the bluetooth apparatus at the transmitting terminal transmits the stream media files to a bluetooth apparatus at a receiving terminal through an Object Push Profile (OPP); the bluetooth apparatus at the receiving terminal plays the received stream media files. It is because the bluetooth apparatus at the transmitting terminal transmits the stream media files through the OPP and the bluetooth apparatus at the receiving terminal receives and plays them, and then the waiting time for playing is reduced. It is solved the problem in the prior art that audio or video playing can be carried out only after the completion of the transmission by bluetooth and the waiting time is longer.

    摘要: The present invention provides a process for producing lower olefins from methanol or dimethyl ether. The technical problem mainly addressed in the present invention is to overcome the defects presented in the prior art including high operation temperature, low yield and selectivity of lower olefins as the target products, and poor stability and short regeneration period of catalyst. The present process, which is carried out under the conditions of catalytic cracking methanol and dimethyl ether and the presence of diluting gas, and adopts as a feedstock methanol, dimethyl ether or their mixture, comprises the steps of: a) letting the feedstock firstly enter a first reaction zone to contact with a first crystalline aluminosilicate catalyst having a SiO2/Al2O3 molar ratio of at least 10, to thereby produce a first reaction effluent containing lower olefins; b) letting the first reaction effluent enter in turn at least one second reaction zone to contact with a second crystalline aluminosilicate catalyst having a SiO2/Al2O3 molar ratio of at least 10, to thereby produce a second reaction effluent containing lower olefins; and c) separating lower olefins from the second reaction effluent; wherein the weight ratio of the diluting gas to the feedstock is 0.01-6:1, while controlling the reaction conditions.
