field boundarycondition
field boundarycondition 双语例句
First, based on coupled wave equations of interaction between pump field, Stokes field, acoustic field in SBS process, theoretical model of stimulated Brillouinscattering including noise initiation is constructed, and then physical models ofone-cell and two-cell SBS PCM for numerical simulation are built up. Using animplicit finited. ifferencing in time and a down-wind differencing scheme in space, the differencing form of coupled wave equations is established, and boundarycondition and initiate condition in the form of time and space net are given.
首先由受激布里渊散射过程泵浦场、斯托克斯场和声子场相互作用的耦合波方程组，建立了包含受激布里渊散射噪声起源的理论模型，接着建立了用于数值计算的SBS单池相位共轭镜及双池相位共轭镜的物理模型；在时间上使用隐式有限差分法，在空间上使用后向差分法，建立了耦合波方程组的差分格式，并给出以时间网格和空间网格表示的边界条件和初始条件。
On the other hand, the latter issimplified as linear elastic media, and satisfies the radiation condition at the artificialboundary. In practical computation, the far-field infinite domain is truncated. Aboundary condition is imposed on the artificial boundary to model the energyradiation effect of the truncated infinite domain, which is called artificial boundarycondition or nonreflecting, transmitting, absorbing, radiation boundarycondition.
前者包含结构以及可能的非均匀和非线性因素，采用有限元法模拟；后者简化为线弹性介质并满足辐射条件，分析中被截去，通过在有限域的人工边界处施加人工边界条件(或称无反射、透射、吸收、辐射边界条件)模拟其波动辐射效应。
