一,名词解释(每题 1 分,共计 10 分) 1. Consolvency: The solubility of weak electrolytes and nonpolar molecules can be increased by the addition of water-misible solvents. This process is known as Consolvency. 2. Tincture: are alcoholic or hydroalcoholic solutions prepared from vegetable materials or from chemical substances. 3. Flocculation: particles experience attraction at significant interparticle distance and form the fluffy aggregates. 4. Isotonic solution: solutions that have the same osmotic pressure as the body fluid. 5. Critical relative humidity: is defined as the relative humidity of the surrounding atmosphere at which the material begins to absorb moisture from the moisture, below which it will not absorb atmospheric moisture. 6. Displacement value: weight ratio of the drug substance and the base having the same volume as the drug substance. 7. Extracts (浸膏剂): traditional Chinese medicine is extracted with solvents, and the solvent is completely evaporated, getting the semisolid state or powder state substance is called extracts. 8.

9. Sedimentation volume: is expressed by the ratio of the equivalent volume of the sediment to the total volume of the suspension. The higher, the better stability. 10. Wet gum method: also referred to as the 4:2:1 method, used to prepare emulsion. Every 4 parts by volume of oil, 2 parts of water and 1 part of gum are added in preparing the initial emulsion. Mucilage of the gum is prepared by triturating the emulsifier with water, the oil is then added slowly in portion, and the mixture is triturated to emulsify the oil. 二,填空(每空 0.5 分,共计 20 分) 1.
