不变性

The quality of service can be measured by service continuity or reliability, uniformity of voltage at the proper level, proper and uniform frequency of the alternating voltage.

供电质量可由供电连续性或供电可靠性，在标准电压等级下的电压均等性，交流电压频率的正确不变性来度量。

The effects of small angle rotation of texture images and noise to the parameterestimation of Gauss-MRF model are researched.

研究了工件表面纹理图像的小角度旋转和噪声对高斯马尔可夫随机场模型的参数估计的影响，数据分析表明高斯马尔可夫随机场模型所估计的参数对于小角度的旋转纹理具有不变性。

It has been widely used in recent years, for it not only preserves several advantages of B-spline surface, especially the affine- invariance, but also has some special advantages such as adaptability to arbitrary topology which parameter surface doesn't have.

它不仅具备B样条曲面仿射不变性等良好性质，还具有参数曲面所没有的任意拓扑适应性等特点，因而近年来得到了广泛的应用。

This technology not only preserves the properties of localness and affine-invariance of B-spline surface, but also has some special advantages such as adaptability to arbitrary topology which parameter surfaces dont have. These good qualities makes subdivision surface used widely in recent years.

它不仅具备B样条曲面的局部支承性、仿射不变性等良好性质，而且具有参数曲面所没有的任意拓扑适应性等特点，因而近年来得到广泛的应用。

The Immutability of God is a necessary concomitant of His aseity.

上帝的不变性是必须随伴著上帝的自存性的属性。

In this manner Van Til discusses all the incommunicable attributes of God: aseity, immutability, infinity, and unity.

范泰尔这样讨论了上帝所有不可传递属性﹕祂的自足性、不变性、无限性和合一性。

In addition, rotation invariance for the images with an axis of symmetry is developed by using a straight line filter.

此外，研究采用直条滤波器使系统在识别狭长主轴图像时具有旋转不变性。

This paper presents a fast algorithm based on the measured equation of invariance.Conformal meshes are made along the surface of two-dimensional scatterer.Renumbering of nodes changed the original sparse matrix into band one,and the consumption of computer memory and CPU time decrease from O(N2) to O.Via this new algorithm,electrically large problem can now be rapidly solved.

提要 本文基于不变性测试方程法提出一种快速算法，在二维散射体表面建立共形差分网格后，通过对节点的重新排序，将原问题中的稀疏矩阵变换为带状稀疏阵，从而使占用的计算机内存和计算时间均由O(N2)下降为O，可以解决原来无法计算的问题。

In the image feature extraction stage, both global image features and local image features are introduced in this paper including gray-scale pixel values, Gabor Wavelet Filter, Local Binary Pattern, Scale Invariant Feature Transform and etc. In our experiments we focused more on Scale Invariant Feature Transform method and analyzed the detailed performances of these different methods for representing gender information.

在性别特征提取阶段，文中详细讨论了人脸图像全局特征和局部特征的提取方法，例如基于图像灰度的全局特征提取方法，基于小波滤波器变换的特征提取方法和基于局部二值模式的特征提取方法等，并提出了一种基于尺度不变性的特征变换提取方法。

Recently, we defined the uniruledness of symplectic manifolds and proved that symplectic uniruledness is invariant under symplectic birational

最近，我们给出了Uniruled辛流形的定义并证明了其在辛双有理变换下的不变性，为今后进一步从事辛双有理几何的研究打下了基础。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
