查询词典 breakthrough point

The reference domain is assumed to be a bounded open set of R~N with boundary Γ of class C~2. We investigate in this paper the null controllability for the semilinear parabolic equations in non-cylindrical domains. The fixed point method is used in the proof.

本文讨论了定义在上述非柱形区域中的半线性抛物方程零能控性，我们使用的方法主要是通过同胚映射将非柱形区域中的抛物方程转化为柱形区域中的抛物方程，再利用不动点方法得到半线性抛物方程的有关结果。

This indicates that it is impossible to design a Clarke-Gawthroptype self-tuning controller or an adaptive pole placement controller for unknown nonminimumphase plants to track arbitrary bounded set point sequences asymptotically.

这表明对未知离散非最小相位系统，不可能设计Clarke－Gawthrop型自校正控制器或自适应极点配置控制器去渐近跟踪任意有界设定序列。

It analyzes the cost of internal trade according to the transaction theory, concluding that the internal trade has certain limitations; From the aspect of asset specialization it also analyzes that the bounder of internal trade is the point at which internal trade cost is equal to the external trade cost; It shows that the internal trade will finally come to an end due to the specialization, monopoly and low efficiency it incurs.

借用交易成本理论，分析了内部贸易的成本，从而得出内部贸易有一定限度的结论；从资产专用性的角度分析了内部贸易的边界：内部贸易成本等于外部交易成本；从内部贸易所产生的专业化、垄断和低效率的角度，提出内部贸易会走向解体或终结。

You'll also notice a bounding box around the particles to indicate that the point cloud is selected.

同时有一个边界盒子围绕在粒子群周围标志着粒子当前为选择状态。

A white bounding box around the particles indicates that the point cloud is selected.

环绕粒子的一个白色的方块显示点云为选择状态。

A modefied egg function has been proposed and used in a bounding surface model. This model has potential value of applicaton since it reflects better actual situation of soil mass under loading. That is: when a stress point is still within the yield surface, the unrccovered plastic deformation would occur as stresses change, and using closed smooth function makes stress modification in the FEM much easier.

文中提出了一个改进蛋形函数，并采用这个函数建立了边界面模型，该模型由于机理上更好地反映了土体受荷时的实际情况，即当应力点在屈服面内时，随着应力状态的改变，仍然可以产生不可恢复的塑性变形，而在计算功能上由于使用了封闭光滑的边界面，不存在角点问题使有限元程序计算显得很方便，从这两个方面看，该模型具有潜在的应用价值。

From the macro point of view, Tao is boundless.

从大的角度看，道是无限的。

Right " foreigner ", want to upgrade, either the sort of in the past having what product lets point of sales sell what product, capture a few big clients however, understand their requirement deep; Right " fellow-townsman ", want development, arrive deep truly namely " fellow-townsman " bourg, is not the level that keeps in prefectural class merely.

对"老外"，要升级，不是过去那种有什么产品就让销售点去销售什么产品，而是抓住几个大客户，深入了解他们的需求；对"老乡"，要深入，就是真正深入到"老乡"的村镇，而不是仅仅停留在县级的层面。

C?tes de Bourg is located on the right bank of the Dordogne at the point where it meets the Gironde river.

波尔山坡位于多尔多涅河的右岸，正好在纪隆德河的交汇处。

Listen and point the pictures even know it, Bowden said.

你可以进行一些自信训练。

We were well on the path to making a rear-wheel-drive global platform," says Mays."

我们正致力于建立一个后轮驱动的平台，"Mays这样说道。"
