推理论

I think today and of everybody communication is a few shifts that extend about the website, learn those who cross market sale theory to know, to the promotion sale of product and service, nothing more than two kinds of methods, what plant even if push is politic, what plant even if pull is politic.

我今天想和大家交流的是一些关于网站推广的手段，学习过市场营销理论的都知道，对产品和服务的推广销售，不外乎两种手段，一种就是&推&的策略，一种就是&拉&的策略。

Equidistance point and difference theory in theory of function approximation are studied. Meanwhile, the relation among difference, difference quotient and derivate is revealed. By drawing Lagrange's and Cauchy's theorem of mean on difference and Taylor's formula into difference function, four theorems, such as Lagrange's theorem of mean on difference, are concluded in simple way. On the basis of these conclusions, the asymptotic property of middle point is studied, a series of new conclusions are drawn and the discussions on the asymptotic property of middle point in differential mid-value are summarized.

为了研究等离子体各向异性及确定高温等离子体中电子束的存在，研制了X射线极化晶体谱仪，探讨了极化光谱学的理论，推演了X射线极化度的计算方法。

Based on the optimal filters, various recursive algorithms of the optimal smoothing estimation under white-noise condition are derived, and problems of reducing storage requirements and computational load for the fixed-interval smoothers are discussed, moreover, optimal smoothers under various noise conditions are proposed, thus, the optimal state smoothing theory is founded.

在最优滤波算法的基础上，本文推导出白噪声情形下的状态最优平滑估计的各种递推算法，讨论了减少固定域平滑的存贮空间和提高运算速度问题，并提出了在多种噪声条件下的平滑估计方法，从而建立了这类系统的状态最优平滑估计理论。

Content Summary:It introduces the main ideas and discussions of the theory for spacetime of multimetrice of multiverse to be tangency each other:The theory reasones out the entire process for the evolvement of multiverse ;It clarifies the radixes of physics about the statistical law of quantion and the wave particle duality of matter and the uncertainty principle .

内容提要：介绍了正交的多度规多宇-时空理论的主要思想和论述：它推演-宇宙演化全过程；阐明的量子现象服-从统计率，物质具有波粒二象性和测-准率的物理根源。

Finally, the influence of permanent tide is recalculated using the same precise development of TGP. This work can be taken as a theoretical reference for the research of highprecision space geodesy and astrogeodynamics. tide-generating potential ; station displacements ; spectrum method ; Love/Shida number

最初的Love数和Shida数是由静态球形地球的潮汐模拟理论推求的，由于地球是旋转椭球形的天体，地球形变对引潮力位的响应存在着不同调和函数的微小混合，这样Love数和Shida数就与测站纬度和TGP的调和级次有关，纬度特性可通过引入一组常数来表示，最初的结果由Wahr

To remove the large deformation with single arc and crack, J integral theory has been applied in studying on the calculations and experiments of straightening shaft with single-edged crack, the straightening feasible field of shaft and the straightening stoke sequential equation have been proposed.

针对单弧度弯曲大变形校直问题，首先根据弹塑性断裂力学中J积分有关理论，建立了含单边径向裂纹轴的校直行程可行域，并根据实验，建立含单边径向裂纹轴的校直行程递推算法。

The paper first proposes"history and on-line memory based on frame"adaptive modification method on roll-gap set value for model set of the gauge control system because of the uncertainty of the switch between two kinds of position closed-loop work state in practice. The method is affirmed to be good by a lot of locale true data and provides a theory method for research on self-study by which parameters can be set by form.

厚控系统模型设定中，针对实际系统运行时两种位置闭环工作状态切换的不确定性，对辊缝设定值首次提出了&基于框架历史实测存贮修正&的自适应修正方法，经大量现场实测数据推演证实了该方法的有效性，为采用以表格方式进行参数设定与自学习研究提供了一种理论方法。
