初始值问题 meaning in English
initial value problem
initial-value problem
Examples
- The second one is to search approximative character points on fixed rigid body within design space , whose mathematic model is nonlinear and non - differential problem with multiple constraints
初始值问题是长期困扰机构优化综合的一个难题，初始值的好坏决定着优化过程的计算速度最优值的好坏。 - By the structure of weak entropy solution of corresponding initial value problem and the boundary entropy condition which was developed by bardos - leroux - nedelec , we give a construction method to the weak entropy solution of the initial - boundary value problem
由相应的初始值问题弱熵解的结构和bardos - leroux - nedelec提出的边界熵条件，给出初边值问题弱熵解的一个构造方法。 - Compared with the initial value problem , the weak entropy solution of the initial - boundary value problem includes the following new interaction type : a central rarefaction wave collides with the boundary and the boundary reflects a new shock wave which is tangent to the boundary
与初始值问题相比较，初边值问题的弱熵解包含了以下新的相互作用类型：中心稀疏波与边界相撞，边界反射出一个与之相切的新激波。 - If the inviscid solution includes the interaction that a central rarefaction wave collides with the boundary and the boundary reflects a new shock wave which is tangent to the boundary , or the inviscid solution includes some shock wave which is tangent to the boundary , then the error of the viscosity solution to the inviscid solution is bounded by o in l1 - norm ; otherwise , as in the initial value problem , the error bound is o
如果无粘解包含中心稀疏波与边界相撞且边界反射一个与之相切的新激波这样的相互作用，或者无粘解包含与边界相切的激波，那么在l ~ 1 -范数下粘性解与无粘解间的误差界是o ( ~ ( 1 / 2 ) + | ln | + ) ；否则，类似于初始值问题，误差界是o ( | ln | + ) 。
