Examples
- A computer real - time data acquisition device for the measurement of seebeck coefficients and electrical conductivities from 300k to 1000k were designed and installed in the present work . the numerical treatment of the measuring data was discussed also
本项工作中，自行设计制作了一套用于测量300k 1000k范围内的seebeck系数和电导率计算机自动测量装置，并探讨了测量数据的处理方法和过程。 - Numerical simulation is a very important aspect for this research , in which the main task is to solve the system of radiation hydrodynamic equations , especially , we usually do this task using lagrangian coordinates , and in this case the numerical treatment of three - temperature energy equations is a main difficulty
数值模拟是这项研究的非常重要的手段，其核心内容是求解辐射流体力学方程组，而其中三温能量方程的数值处理又是在lagrange坐标下求解辐射流体力学方程组的主要难点之一。 - Important missing aspects are : turbulent flow , numerical discretization techniques specially the relevant and difficult topic of numerical treatment of advection and related numerical methods of solution , variable property fluids , boundary layers , stability , etc . rather , it focuses on more primitive and fundamental issues of numerical treatment of advective equation and proper formulation of initial boundary value ( ib vp ) . numerical problems associated with advective dominated transport include spurious oscillation , numerical dispersion , peak clipping , and grid oriention . however , the key of numerical solution of three - dimensional advective problem is searching for a high - precision interpolating function , which can keep the computational stability and low damping
3 、针对三维纯对流方程提出了实用的拟协调单元模式，并与线性插值模式和协调单元模式比较后表明，在物理量大梯度变化的情况下，线性插值模式会产生较大的数值阻尼，导致解的失真；协调单元模式具有极高的计算精度和良好的计算稳定性，还可较好地克服数值阻尼，但由于计及物理量的二阶导数项，计算工作量大，边界条件给定尚存在一定的困难；而拟协调单元模式不仅具有协调单元模式计算精度高的优点，还避免了物理量的二阶导数项，可大大地减少计算工作量。
