逼近地

Furthermore the numerical flux from the Riemann solver is delicately expressed in a compact manner, say by the well known Godunov flux function, which paves the way to full investigation of numerical approximations.

由上述的Riemann解所提供的数值流通量经仔细验证后可以被简洁地表示为Godunov流通量的函数值，这为研究一般意义下的数值逼近铺平了道路。

In the first Chapter of this thesis, after a short review of the role of solid modellers in CAD and CAM, we explain the importance of robustness for curved or surfaced solid models.

本文将系统地研究区间曲线与曲面的逼近问题，对这些问题的研究，在计算机图形学和机械产品CAD中具有一定的理论价值和良好的应用前景。

The experimental results prove that adopting neural network's nonlinear simulation method to design milling cutter's profile can implement more precise,shorten the design period.

仿真结果表明，采用神经网络的非线性逼近特性进行铣刀刃形的模拟设计，能够精确、快速地模拟出铣刀刃形。

This paper presented the main functions and characteristics of Multisim8.0, and the main qualities of high frequency tunable amplifier such as voltage gain, transmission bands and selectivity were studied using simulation analysis and testing technologies of Multisim 8.0. The results are visual and precise, and prove the theory very well. This software has powerful simulation and analysis function, by which the analysis and design of high frequency circuit are not only more precise and credible, but also more closed to the real circuit running status.

New algorithms and design strategies greatly imp- rove the XXX87's performance, lots of instructions can be finished in a few clock cycles. Newton-Raphson and Polynomial approximation are used to implement division, square root, and elementary functions.

特点是结合牛顿-拉夫逊迭代算法，采用多项式逼近法对初等函数、除法和平方根进行实现，既有效地利用XXX87片内的浮点加法单元和阵列乘法器，又避免了查找表的使用。

Try to manoeuvre around behindhim, using cover as explained in section 9. Recite the Litany ofStealth(refer to Emperor's Benedictions) to decrease your chance ofbeing heard. Creep up behind him, pull his head up sharply to exposehis neck then thrust your knife deeply into the side of his throat.

你可以尝试迂回到他的背后，找一些掩护（在第九节的一些段落中会给出详细解释），从背后慢慢地逼近他，扑上去猛地扭起他的头，朝他他暴露的脖子上捅上一刀。

Solveing to some extent problem to define hidden layer node number of feed forward networks,and makeing successfully it to apply to solve weierstrass theorem of that is polynomial approach continuous function;and establishing dynamic mathematical neural networks of Romberg integration.

从而在一定程度上解决了前向神经网络隐层结点数无法确定的难题，并成功地将其运用于解决用多项式逼近连续函数的魏尔斯特拉斯定理，并建立了龙贝格求定积分的动态数学神经网络模型。
