Design requirements Experimental design to be scientific, safe and reliable, easy to operate, pharmaceutical economy, the phenomenon is obvious. 2. General process (1) According to a topic, “found the problem ” “put forward the conjecture ”To determine the hypothesis"; (2) based on the hypothesis of the design of experimental programs; (3) to collect evidence or experimental phenomena through experiments; (4) to make conclusions on whether the hypothesis holds; (5) to reflect and evaluate the conclusions; Method (1) analyze the questions to the conditions, a clear experimental purpose;
