摘要: Blends of two or more polyethylenes are made by reacting ethylene with an oligomerization catalyst that forms &agr;-olefins, and two polymerization catalysts, one of which under the process conditions copolymerizes ethylene and &agr;-olefins, and the other of which under process conditions does not readily copolymerize ethylene and &agr;-olefins. The blends may have improved physical properties and/or processing characteristics.

摘要: Polyethylenes made from ethylene and a series of &agr;-olefins using a catalyst that copolymerizes ethylene and &agr;-olefins usually have excellent melt processing characteristics, especially in uses where high zero shear viscosity and low high shear viscosity are desirable. These polyethylenes are preferably made by forming the &agr;-olefins in situ from ethylene during the polymerization process. The polyethylenes are especially useful in blow molding, extrusion or extruded blown film processes.

摘要: The disclosure discloses a method and device for power control in non-adaptive retransmission. The solution thereof includes: when UE does not obtain a TPC adjustment value of a current HARQ process by parsing, determining a current power control mode; if the mode is an accumulation mode, determining whether the calculated sum of TPC adjustment values of each HARQ process is smaller than a given threshold, if yes, obtaining a transmission power by adding an increment adjustment value to a retransmission power, otherwise, calculating the transmission power of UE according to a formula in a protocol; if the mode is an absolute value mode, obtaining a transmission power by adding an increment adjustment value to a retransmission power. The solution can improve the SINR detected by an eNB and improve a retransmission success rate, thereby saving radio resources, facilitating utilization of radio resources and reduction of transmission delay, improving the throughput rate of an LTE system and improving the system performance.
