    摘要: The present invention refers to dental self-curing resin compositions having enhanced mechanical and physical properties. In particular, the present invention relates to dental self-curing resin compositions consisting of (i) a Paste A composition containing the multifunctional prepolymer mixture of 2,2-bis-[4-(2-hydroxy-3-methacryloxypropoxy)phenyl]propane (“Bis-GMA”) and multifunctional prepolymer formed by substituting hydrogen atoms in hydroxyl group with methacrylate groups in the Bis-GMA molecules, and further containing a diluent, an adhesive monomer, a polymerization initiator, a polymerization inhibitor, a light stabilizer, an antioxidant, an inorganic pigment and an inorganic filler; and ii) a Paste B composition containing the same prepolymer mixture in the Paste A composition, and further containing a diluent, an adhesive monomer, a reductant, a polymerization inhibitor, a light stabilizer, an antioxidant, an inorganic pigment and an inorganic filler. The composition according to the present invention has better physical and mechanical properties than that of conventional compositions and is an ointment-ointment system able to be conveniently used.

    摘要: A circuit module for a silicon condenser microphone of the present disclosure includes a transducer, a charge pump, an isolator, a first amplifier, a second amplifier, a reaction circuit, a first bias circuit, and a second bias circuit. The charge pump electrically connects to an input port of the transducer, and an output port of the transducer electrically connects to an input port of the first amplifier via the isolator. An output port of the first amplifier electrically connects to an input port of the second amplifier. The reaction circuit is arranged between the output port of the first amplifier and the input port of the transducer. The isolator isolates the direct-current components of the first electrical signal, and therefore, the oscillations of the direct-current components will not affect the performance of the first amplifier.
