反拉氏变换 meaning in English
inverse laplace transformation
Examples
- In order to overcome the difficulty mentioned above , this paper provides an improved heat transfer equation and a mended bem for the problems . first of all , the enthalpy and the " virtual temperature " are introduced into the paper to eliminate several mutative thermophysical properties in the heat transfer equation . secondly , the movement of the boundary between the solid and liquid phases in the billet is educed by virtue of the laplace transform
这些改进包括：引入热焓和“虚拟温度”的概念，对非常数的热物性参数进行整合：充分考虑铸坯凝固潜热释放带来的影响，利用“温度回升法”来加以处理；利用拉氏变换和反拉氏变换的原理来对凝固过程中铸坯内部固液相界面的移动方程进行了推导和求解，在凝固过程中充分考虑铸坯内部的固液两相的影响等等。
