The corresponding frequency of the key parts of the poplar particle presswood pallet at maximal transmissibility was determined by frequency sweep test.
In this paper, ACO algorithm is reviewed by and large.Firstly, the corresponding principle of biont and the implementing framework for ACO algorithm are introduced simply.
RESULTS The chlortetracycline's epimer, tetracycline and its epimer, as impurities in chlortetracycline have been determined by the liquid chromatogram and its first order mass spectrum.
This paper intends to report three experimentally simple preparations of naphthoquinone, hydroquinone and the corresponding mixed quinhydrone,all redox chemistry being carried out in the solid state.
A method based on the resistance-displacement relationship of shape memory alloy(SMA) spring that can adjust the nonaxiality of small-diameter pipe inner surface inspection sensor is proposed.
The two transpolar shortwave time signal circuits,Moscow and Irkutsk to the Great Wall Station in Antarctica, are used to study the fading characters for shortwave long circuit.
According to the results of the temperature dependencies of the intensity, linewidth and resonance field, we conclude that the peak at T(subscript M2) is a transition of antiferromagnetism.
Based on the experiment it is validated that the system load would impact the inhibitable equation, that is, the certain load would make a corresponding proper allocation proportion.
