[Revealing the essence of powders: from the base to the application].

My main research fields are powder technology, especially solid dosage form, from basic ones to applied ones. Basic ones are physical properties of powder and its packing, compression and computer simulation. Applied ones are preparation and evaluation of granulation, tableting, improvement of solubility of water poor-soluble drug, controlled release tablet and fast disintegrating tablet in the oral cavity. As the chair man of the Standard Formulation Research Council, I have obtained many variable and excellent results. Several results are shown as follow.
