将此法应用于弹性有限位移理论中,除了得到前人得到的变分泛函外,还得到了一对新泛函—狭义泛函。
Using this method in finite displacement theory of elasticity, we found not only variational functionals obtained by predecessors but also a pair of new functionals-narrow functionals.
图像的卡通部分是由一个有界变差(BV)函数来刻画,相应的将BV罚项合并到变分泛函中需要解偏微分方程。
The cartoon component of an image is modeled by a bounded variation (BV) function; the corresponding incorporation of BV penalty terms in the variational functional leads to solve PDE equations.
