摘要： Ultra fine and nanometer powders and a method of producing same are provided, preferably refractory metal and ceramic nanopowders. When certain precursors are injected into the plasma flame in a reactor chamber, the materials are heated, melted and vaporized and the chemical reaction is induced in the vapor phase. The vapor phase is quenched rapidly to solid phase to yield the ultra pure, ultra fine and nano product. With this technique, powders have been made 20 nanometers in size in a system capable of a bulk production rate of more than 10 lbs/hr. The process is particularly applicable to tungsten, molybdenum, rhenium, tungsten carbide, molybdenum carbide and other related materials.

摘要： A system and method for communicating includes a transmitter that transmits a communication signal having a plurality of successive frames, with each frame formed with alternatively arranged N known data symbols and M unknown data symbols such that the N known data symbols as training symbols. The communications signals are received within a receiver. The N known data symbols are synchronized at the receiver by correlating and time averaging the N known data symbols.
