不变的

In classical mechanics the resistance of a given body was something unchangeable, characterized by its mass alone.

在经典力学中，一个既定物体的抗力总是不变的，它仅由物体的质量来决定。

In view of this, a one dimension polar distance sequence is obtained first from the closed planar curve and then the auto regressive model of this sequence is used to extract feature vector.

从空间旋转不变的要求出发，首先从平面闭合曲线得到一维极径序列，进而采用该序列的自回归模型来完成特征提取并用于平面曲线的形状分类。

Experimental results prove that extracted features using phase congruency is invariant to image illuminance and noise.

实验证明，相位叠合提取特征对图像的照度以及可能出现的噪声是不变的。

In one direction there is a constant gravitational force, in the other very many irregular blows from the molecules.

在一个方向上有不变的重力在作用，在另一个方向上则是分子的大量不规则的碰撞。

For certain type of investment, the expected rate of return is relatively constant; therefore the price is determined under a defined investment environment.

对于同一类投资，它的投资回收率是相对稳定不变的，因而当投资环境确定时，价格也是明确的。

The proportion in DEA inefficiency, in decreasing return to scale or in increasing return to scale of various types of universities decreases; and the proportion in constant return to scale increases.

只是相对综合评价，各类型中的非DEA有效高校、处于规模收益递减或递增状态的高校比例都减少；而规模收益不变的比例增加了。

Secondly, to relax the hypothesis of constant return to scale and redefine the space of technique sets, the decomposition method of the growth of labor productivity has been improved. Using the corrected decomposition method of the labor productivity's growth, the paper analyzes the drivers of evolvements of regional disparity in labor productivity of manufacturing, perspective on the performance of growth.

其次，在放宽规模报酬不变的假定和重新定义技术集空间后，本文利用改进的增长分解方法，对制造业劳动生产率的增长进行了分解，从增长绩效角度剖析了地区差异演变成因。

So far we've been talking about special relativity, which applies to objects moving at constant speed.

但迄今为止，我们谈论的一直是狭义相对论，这种理论适用于在速度不变的情况下移动的物体。

For incompressible fluids, both the mass flux and the volume flux are constant in a tube of flow.

对于不可压缩的流体来说，流管中的质量通量和体积通量都是恒定不变的。

It is our commitment to quality and cheap, your satisfaction is our constant pursuit!

质优价廉是我们的承诺，您的满意是我们不变的追求！

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。

Designed by French fashion house Herm è s, this elegant uniform was manufactured in our home, Hong Kong, and was the first without a hat.

由著名品牌 Herm è s 设计，这件高贵的制服是香港本土制造，是我们第一套不配帽子的制服。
