The method includes: receiving a first short message sent to a recipient user terminal, where the first short message carries sender information and recipient information of the short message; selecting, according to the sender information and recipient information of the first short message, a short message icon identifier to be displayed by the recipient user terminal; and sending a second short message to the recipient user terminal, where the second short message carries the selected short message icon identifier so that the recipient user terminal displays, according to the selected short message icon identifier, a short message icon corresponding to the selected short message icon identifier. The present disclosure enables more convenient and flexible displaying of a short message icon.

Abstract: Methods are disclosed for replenishing tin and its alloying metals in an aqueous electrolytic plating bath using an acidic solution containing stannous oxide. During electroplating of tin or tin alloys the stannous ions and alloying metal ions are depleted. To maintain continuous and efficient electroplating processes predetermined amounts of the plating bath containing tin and its alloying metals are bailed out. The bail out is then mixed with a predetermined amount of acidic solution containing stannous oxide and any alloying metals. The mixture is then retuned to the plating bath to return the stannous ions and alloying metal ions to their steady state concentrations.
