superpose
2.Based on the FEM of the coupled acoustic-structure system, the acoustic response feature is deduced and performed, the modal superpose method of the acoustic-structure sensitivity is put forward and performed;
3.Using Abel transformation formula, this paper educes concerned proposition about Dirichlet series . On this base, studies the relation between absolute convergence and series convergence, then educes the simple method to find the abscissa of convergence when the abscissa of convergence and the abscissa of absolute convergence superpose .
4.While two (or more) electromagnetic waves of the same frequency, same direction of vibration, same phase or constant phase difference superpose in space, the amplitude of composite wave is vector sum of the amplitude of each wave.
5.Of special besmirch clear: Oily be soiled, paint, printing ink can be used special go be soiled oil is wiped; The incomplete be soiled such as bloodstain, fruit juice, red wine, beer uses wet rag or dip in with dishcloth on right amount floor cleaner is wiped; Candle and chewing gum, with ice cube superpose a little while, those who make is refrigerant and contractive, next gently sweep, reoccupy wet dishcloth or dip in with dishcloth on right amount floor cleaner is wiped.
