Based on the time-frequency analysis (continuous wavelet transform and short time Fourier transform), the arithmetic uses the modulus maximum characteristic on the phase scale and carry frequency scale to recognize phase modulation rule of signal. So without whole wavelet coefficient the signal mathematics model can be obtained quickly. It provides well condition for application of arithmetic in practice.

该算法基于信号的时频分析（小波分析和短时傅里叶变换），利用小波变换的相位尺度和载波尺度的模极大值特征辨识信号的相位调制规律，因而在无需计算全部小波系数的情况下，可快速地获得信号的数学模型，为算法在实际中的应用提供了良好的条件。

The overall results of sensitivity and safety of explosives is characterized by addition and product of relevant data obtained in various tests. The sensitivity of JB-9001、 TNT、TH4748、JOB-9003、RHT-901 and JO-9159 are classified using fuzzy mathematics, sensitivity and safety of explosive are evaluated by comparing nearness of tested explosive with standard explosive.

用多种感度试验方法来综合评定炸药的安全性能，把炸药的各单个安全性能表征后分别相加、相乘就可以得到炸药的感度与安全性能综合表征结果；用模糊数学对JB-9001、TNT、TH4748、JOB-9003、RHT-901、JO-9159炸药的感度进行聚类分析，比较被测炸药与基准炸药的贴近度来评价炸药的感度和安全性。

A study was performed of the randomness of external loads on high arch dams,including flood,earthquake,landslide of mountains,etc.,the weakening of concrete strength of arch dams and rock strength of dam foundation,and the fuzziness of evaluation criterion.The disadvantages of conventional deterministic assessment methods for the safety of arch dams based on the strength theory and stability theory were analyzed respectively.It is suggested that fuzzy mathematics theory should be introduced to safety evalua...
