Is as follows : according to energy integral of parseval equation of fourier transform , we get 根据傅氏变换的能量积分的巴塞瓦parseval等式:
The product theorem of asymptotic expansions of the energy integral for elliptic partial differential equations 椭圆型方程能量积分渐近展开的乘积定理
Both electric stress and thermal stress had been considered comprehensively during the calculating process . according to the failure criterion , the temperature was chosen correspondingly . then using the energy integral way , the life of device can be deduced 在计算寿命的过程中,综合考虑了电应力和温度应力,根据失效判据,选取实验过程中相应的温度段,采用能量积分的方法来外推器件的寿命。
After the original data acquired from the experiment were filtered by wavelet transformation , the energy integral of the filtered signal was taken as stress wave factor ( swf ) , from which the material can be distinguished between demage and undamage , and the degree of damage can be qualitatively estimated 在对所得试验信号进行小波滤波后,应用了能量积分方法量化应力波因子,据此值可以区分材料有无损伤,并可定性地评估损伤程度。
