保持不变的

• The unwanted change of the value of an output signal of a device over a specified period of time when the values of all input signals of the device are kept constant
  在设备的所有输入信号的值保持不变的情况下，该设备的输出信号的值在规定时间内产生的不希望的变化。
• This way seems to avoid partition function , but study the transformation that makes partition function unchanged . these transformations are made up of renormalization group
  它回避了直接求配分函数，而代之以研究使配分函数保持不变的变换，这些变换构成所谓重整化群。
• The levels of melanin generally remain the same throughout life , but a few things can change them permanently . the first is a handful of ocular diseases like pigmentary glaucoma
  而基质中的黑色素含量在通常情况下是终生保持不变的，除非某些异常情况发生导致它发生永久性的改变。
• The form of variable cross - section , used mostly in the practical projects , just has the change of the linear variation on the height of the web plate while keep the width of the flange c hangeless
  实际工程中使用最多的变截面构件形式是仅构件腹板高度线性变化，翼缘宽度保持不变的形式。
• The results of the simulations show this method can keep the amplitude of the desired signal , restrain the interference signal , and keep the output power of array to minimum
  仿真表明，采用自适应算法能够在保证接收方向回波信号幅度保持不变的条件下，抑制干扰信号，且使阵列输出功率最小。
• This way seems to avoid partition function conceptively , but study the transformation which makes partition function unchanged . these transformations are made up of renormalization group
  这种方法从概念上看它回避直接求配分函数，而代之以研究使配分函数保持不变的变换，这些变换构成所谓重整化群。

• Steve miller , who tracks leveraged loans for s & p lcd , says that since the formation of the market in the 1980s , spreads and leverage have risen and fallen “ like hemlines ” and only covenants have remained constant
  史蒂夫?米勒跟踪调查标准普尔的’杠杆贷款报告”后发现，自二十世纪八十年代市场形成，它的拓展和杠杆作用起伏很大，而只有契约是保持不变的。
• Invariant content - based image retrieval has widely application foreground . using the rotation , scaling and translation invariant features can get better retrieval results than normal color , texture and shape features
  对旋转、平移、尺度缩放保持不变的图像特征,比起普通的颜色、纹理、形状特征,可以得到更加优良的检索结果,因此基于不变特征的图像检索有着广泛的研究前景。
