1. can be seen by the result in the table: when the ratio of drug extract and substrate was 1: 1, its rounding rate, the ball method of double differences was different and index such as hardness is all undesirable, and dissolve scattered time limit influenced not obvious.
2. when the ratio of drug extract and substrate is 1: 3, the rounding rate, the ball method of double differences is different and index such as hardness slightly all begins to enter preferable state.
3. when the ratio of drug extract and substrate is 1: 9, though the rounding rate, the ball method of double differences is different and index such as hardness has raising, and is not obvious.
4. the general effect of composite interstitial substance is better than single-matrix.
5. the hardness method for expressing in the subordinate list adopts drop pill is placed on the glass plate, press...withes one's finger it, observes its metamorphosis."+" expression flicking promptly is out of shape, " ++ " expression distortion of firmly pressing, and " +++" expression is indeformable by it.
