    摘要: A time division multiple access (TDMA) controller and method for operating the same includes a frame position module that generates a frame position signal. The controller also includes a signal module that generates a signal-on signal and a signal-off signal and a comparison module that generates a timing control signal based on the frame position signal, the signal-on signal and the signal-off signal.

    摘要: There is provided a method for rectifying a vinyl compound liquor. The method includes the steps of a) providing a rectification column operated at a temperature and pressure and b) feeding the vinyl compound liquor to be rectified into the rectification column, wherein the pressure of the rectification column and the temperature of the fed vinyl compound liquor are controlled, such that the temperature of the fed vinyl compound liquor ranges from its bubble point at the pressure of the rectification column to 10° C. lower than the bubble point.
