积分域

介绍了EMT电磁场中的积分域和积分形式问题。

The Integral domain and integral pattern in EMT electromagnetic field .

这里的积分域是这个1/4圆。

And , the region will just be , now , this quarter disk here .

它的积分域是什么？

What is the range of integration ?

由于在推导过程中，没有对积分域进行缩放，因此所得结果减少了保守性。

Without any integral area reduction , some conservativeness is reduced in the obtained results .

如果用另外一种方法计算，就要重新分解积分域了。

So now , if I want to do it the other way around , I have to decompose my region .

但通常都要画出积分域的图像，观察两种不同积分次序中切面的形状。

But in general , I have to draw picture of my region , and see how the slices look like both ways .

但自然单元法形函数其局部支撑域与背景积分域不一致，从而导致了相当的积分误差。

But the integration domain does not align with the compacted support of the NEM shape function , which results in considerable integration error .

但若是积分域形状比较古怪的话，某一积分次序可能比另一种更简便些。

Sometimes it will be that because the region has a strange shape , you can actually set it up more easily one way or the other .

但是从虚位移原理化为能量关系的变分形式时，要求位移和应力在积分域内处处连续。

The transformation of virtual displacement principle into the varia-tional energy form is performed on the bases of continuity conditions of stress and displacement throughout the integrated space .

但如果切面取在最前方附近，实际上，积分域。

But , if I take a slice that , say , near the very front , then in fact , only a very small segment of it will be in my region .

通过叠加原理给出了含有裂纹的介质层的拉梅势函数在Laplace积分变换域中的解以及相应的位移和应力解。

The solutions of the Lame potential functions and the solutions of the corresponding displacement and the stress in the Laplace transform domain of the composed medium with crack were given using superposition principle .

如果进行积分的球面域小于半球面，反演将是唯一的。

If the integrated area is less than half spherical surface , inversion will be unique .

用高精度的数值积分法将谱域格林函数经逆傅里叶变换，求得了格林函数的空域结果。

文中还解释了道积分算法在频率域的物理意义&在有效频带对地震记录做-90°相移。

The paper also interpreted the physical meaning of trace-integrated algorithm in frequency domain-making the seismic data shift-90 ° of phase in effective frequency band .

针对波动方程空间坐标进行有限积分变换的混合域方法（有限积分变换&有限差分方法）所具有的降低问题的维数及变换方向上大尺度延伸的优势很值得进行深入和详细的探讨。

For allowing to extend the computation interval to any length without any limitation and reducing the dimensions of the questions , the finite integral Fourier transform finite difference method is worth extending and improving .

本文介绍一种带智能积分的全论域自调整因子模糊控制器，经数字仿真和模拟仿真证明这种控制器比一般自调整因子模糊控制器的控制效果更好。

In this paper , a self-regulating factor fuzzy controller with intelligent integral is introduced . By means of the example of the digital simulation and analogue simulation , the control performance of this controller is shown to be better than the regular one .

提出了Riemann积分的可计算性概念，证明了Riemann积分是可计算的当且仅当积分域可以度量化。

The concept of computability of Riemann integrals is proposed and it is proved that Riemann integrals are computable if and only if the spaces are metrizable .
