传导方程 meaning in Chinese

diffusivity equation

( 3 ) we bring bdf method of order two forward as time discrete method for the two - dimension three - temperature heat conduction equations
( 3 )提出使用二阶bdf方法作为二维三温热传导方程的时间离散化方法。
As 2 - d 3 - t heat conduct equations are discretized in a fully implicit method , it is very difficult to solve the nonlinear algebraic equations obtained due to strong nonlinearity
摘要由于二维三温热传导方程具有很强的非线性特性，因此采用全隐格式对该方程离散后，所得非线性代数方程组的求解将变得非常困难。
According to the result of analysis and the fabricating technique of our lab , we designed the parameters of oversized rib waveguide and devices on the polymer / silicon material and simulated the behaviour of the devices by using the bpm method simulation soft named " beamprop "
同时我们利用热传导学中的传导方程和有限差分法对热电极作用下不同材料结构中的热场分布情况作出了分析。利用实验室现有的beamprop软件对器件工作情况进行了详细的模拟，优化了各项设计参数。
