查询词典 numerical system

Numerical reasults show that the LO contribution is affected strongly by the unphysical scale, but when the NLO contribution is included this undesirable situation is not only imporved obviously but also the value is coslstent to the exprimental data with a theoritcal error about 20% in the two-jet system invariant mass range, M〓∈(10, 45)GeV.

计算表明，LO结果显示了强烈的标度依赖性，然而当计人NLO修正量之后，这种不期望的情况显明地得到了改善。

The numerical analysis shows that the effect of an input sinusoidal signal is also a sinusoidal signal in the output, and the effect of the white noise is a Wiener process. When the system parameters are small enough, the effect of signal modulating noise can occur in the stochastic systems.

理论分析表明，正弦信号在系统输出中的数值表现仍为正弦信号，白噪声的效应是维纳过程，较小的系统参数才能使随机共振系统发生信号调制噪声效应。

By making a numerical analysis of the bistable stochastic dynamical systems, we find that the effect of an input sinusoidal signal is also a sinusoidal signal in the output, and the effect of the white noise is a Wiener process. When the system parameters are small enough, the coupling effect between the sinusoidal signal and the white noise can be largely weakened.

随机共振是双稳系统在周期信号和噪声的作用下表现出来的非线性现象，当系统的非线性与信号和噪声之间存在某种匹配时，通过对系统施加适当强度的噪声，可以提高系统对信号的响应，系统输出的信噪比对噪声强度表现出一峰状曲线[11] 。

Finally, a simulated numerical control processing feeding system based on a X-Y motion worktable is realized.

最后，实现了一个基于X-Y运动平台的数控加工模拟进给系统。

The general principle and the applications of numerical derivative zero crossing method is described for resolving overlapped spectra of binary system.

程序中采用TVD格式，可选择不同限制格式如MinMod限制器，SMART限制器等，离散系统用ICCG和Biconjugate Gradients-CG共轭方法求解。

By means of the Fourier series expansion, an approximate analytical propagation equation of flattened Gaussian beams passing through an apertured paraxial ABCD optical system is derived, and illustrated with numerical examples, when the transmissivity of the aperture is T = cos.

用傅立叶级数展开法研究了平顶高斯光束通过有光阑限制的近轴ABCD光学系统的传输特性，导出了光阑透射率为T=cos时的近似解析传输公式，硬边光阑的情况可作为Ω=0的特例得到。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
