1 By the operation rules of unascertained rational number, the expression of unascertained weight coefficient is derived.

2 Based on blind number theory in unascertained mathematics, primary research on water environment risk is made with uncertained information.

3 Present. Unascertained destroyed 36 vehicles, but the unknown cause of the incident, unknown number of casualties.

4 Because of the unascertained information in the reservoir water environmental system, a calculation is made on the water environmental capacity by the use of unascertained mathematics theory.

5 Although the reason for this result is unascertained, the interaction between the auditory sensation and the vibration sensation at the same frequencies is suggested.

6 Applying unascertained rational number to evaluate the achievements of sports gives the reliability of evaluation.

7 Applying the unascertained measure model of synthetical evaluating in environment engineering(), a new method for calculating pollutant weights was raised. The result of evaluating is more reasonable.

8 The unascertained rational number with higher order can precisely simulate the situation of the market and give much information and alternative strategies for the enterprise.

9 In this paper the author uses the unascertained measurement model to evaluate the water pollution degree of Fuyang River.

10 The unascertained mathematical method is introduced and applied to analyzing and processing the data in physics experiment.

11 This method can solve a lot of unascertained problems in ventilation system evaluation, and also can analyze the ventilation system quantitatively.

12 Abstract: This paper gives the unascertained measure estimation model and applies it to the quality estimation of a water environment.

13 The fuzzy, grey and unascertained parameters, events and processes are processed by fuzzy mathematics, grey mathematics, unascertained mathematics and their combination.

14 This phenomenon is particularly prevalent in the case of unascertained future goods where a strict approach is often evidenced.

15 Study result showed that it is feasible in theory and reliable on conclusion using unascertained mathematical theories to simulate river water quality and evaluate its risk.

16 In the paper,[] I Study mathematical treatment method of unascertained information.

17 Based on the uncertainty information handling mathematics-theory, we put forward unascertained quantification and a series of its quality on expert idea.

18 Based on the analysis of the influencing factors of entrepreneurial human capital value, this paper establishes a comprehensive evaluation model of multi-level unascertained measurement.

19 Quantizing method for grade of target threat for missile position, target type space, quantizing parameters space and it's matrix were defined, and the unascertained measurement model was constructed.

20 The measurement function was established by defining single parameter unascertained measurement matrix.

21 Study results show that it is feasible in theory and reliable on results to calculate water environmental capacity under unascertained information by unascertained mathematics.

22 The rules of measurement function for grade of target threat were established, evaluate matrix was defined to obtain multi-parameters unascertained measurement.
