1 The indicatory sign works closely with the fire alarm on fire site changes and chooses the evacuation direction according to the information it has obtained.

2 The paper enumerates several reasons which cause the variation of indicatory values on scales, and introduces means to remove these variation.

3 Results: Determine the end-point of titration by sudden potential change of the indicatory electrode (use E-V curve method).

4 The misreading is that the subject confirms and defines itself according to its priori knowledge, through binarily selecting and filtrating other culture which contains indicatory of value.

5 The expression of BP1 in died group is obviously higher than that in survival group. This study strongly suggests that BP1 is not only an oncogenic gene, but also an indicatory factor for prognosis.
