使不变

Aiming at the big time-delay,big burthen fluctuating and mutable characteristic of the controlled object,combining Smith predicator with PID controller,the BP neural network tuning Smith-PID controlling policy is presented.

针对大时滞时变对象，把Smith补偿控制原理和PID参数的自适应调整方法结合起来，提出了基于BP神经网络整定Smith PID控制算法，即在Smith预估补偿控制系统中，利用BP神经网络在线自学习整定PID参数，使PID参数实现最佳的非线性组合，以适应对象特性的变化，从而克服了常规PID算法不适应大时滞系统控制和常规Smith算法过于依赖模型精度的缺陷。

Compared with the traditional design, no materials and energy are consumed in Virtual Design, and the Producibility for the production are analyzed and estimated beforehand. The feasibility of the production's producing is increased. The application of Expert System can make a design of roller hearth kiln very shortcut and accurate.

与传统产品开发相比，虚拟产品开发不消耗物资资源和能源，而且可在产品投产前对产品实现的方案进行评估和优化，提高了产品实现的可行性，专家系统应用可以使陶瓷辊道窑设计变的非常快捷、准确和及时。

When the concept of electronic business affairs just entered China 1993, its kernel is punch-drunk it seems that, be regarded as morely a fashionable diction will use. 1996, china appears trade on brushstroke net, website of a batch of B2B rises abruptly quickly, casual in become the network more broad, ecbolic the way of life that gives more appearance. 2 timeses, the shop on the net and portal are not fresh topic any more, more and more people learned to be opened on the network achieve rich door, they run concern of business flow, client outspread go up to Internet, make product and service more demand of user of press close to, form new value chain, swim fluctuation interest relative rises jointly, form more efficient strategy alliance.

当1993年电子商务的概念刚进入中国时，它的内核似乎是模糊不清的，更多地被当作一个时尚用语来使用。1996年，中国出现第一笔网上交易，一批B2B网站迅速崛起，不经意中把网络变得更为宽广，催生出更多样的生活方式。2.0时代，网上商店和门户都已经不是新鲜的话题，越来越多的人学会了在网络上打开创富之门，他们把业务流程、客户关系治理都延伸到互联网上，使产品和服务更贴近用户需求，形成新的价值链，把上下游利益相关者联合起来，形成更高效的战略联盟。

In the end, I favor his reappointment, but only because rejecting him could make the Fed's policies worse, not better.

First, we have proved that the constraint of local constant gradient angles is equivalent to the minimization of total variation. Based on this, a stronger continuity constraint of gradient angle is presented. The interpolation formula (a 3-degree-PDE) derived from the constraint can ensure the continuity of level lines and reduce the width of edges. The contrast invariant of the regularizer of the formula is also proved.

首先证明了局部恒定的梯度角约束插值等价于总变分最小化；在此基础上，提出一个具有更强连续性的梯度角约束，由这个约束条件导出的三阶偏微分方程使插值的图像既可以保证水平线方向的连续性，又减小图像边缘的宽度；最后证明了插值方程中正则项的对比不变性。

The indexes of refraction of the material of the fibers in the scrim and of the adhesive are similar so that when the layer of adhesive is pressed against a substrate through the backing layer, the adhesive will more totally wet the fibers of the reinforcing scrim, causing them to become significantly less visible in the reinforced tape adhered to the substrate.
