1. Nondeterminacy relation's reasoning between geometrical bodies in the geometrical space is the main research direction of spatial reasoning.

2. Fuzzy set pair analysis and other methods of nondeterminacy analysis were compared preliminarily.

3. The algorithm used here considers the nondeterminacy of data and hence can overcome the shortcomings of existing algorithms. It is automatic, direct and effective, and needs less running time.

4. In chapter 6, a financial analysis for the invest strategy is made, including the analysis of profitability, repayment ability and nondeterminacy.

5. System model is the foundation of Kalman filter. The nondeterminacy of system model brought on apriori data error, as the low precision and the diverge of the filter.

6. Chinese medicinal clinical healing efficacy showed complicated contradiction with certainty and nondeterminacy.
