不变

Stet: A proof-reader's instruction meaning ignore marked Correction,i.e.let it stand as it was.

保留不变：校对用指示，表示不需理会注着的更改；即是保持原状。

To do so, at first, we introduce the characteristic triple, the invariant subbundle and invariant vector field.

为此，首先引入了特征三元组的概念，并定义了不变子丛及不变向量场。

Then the structure unit of hexangular lattice is found according to the principle of invariable symmetry. Renormalization transformation is processed when we regard the structure unit and the growth model as graphs before and after transformation respectively. After choosing the11thermodynamic function fugacity as parameter, we can write out the partition functions before and after transformation and the formula of renormalization transformation. At the same time, we also work out the fixed points of transformation.

然后根据对称性不变的原则，从整体晶格中选取结构单元，把结构单元和生长模型分别作为重整化变换前、后的图形来进行重整化变换，选取热力学函数易逸度为参量，写出了重整化变换前后的配分函数和重整化变换关系式，求出了这一变换的不动点。

The Fed decision to retain the language that the funds rate will be kept ldquo;exceptionally lowrdquo; for an ldquo;extended periodrdquo; makes sense given the tentativeness of the recovery, the enormous slack in the economy, current low inflation rates and stable inflation expectations.

美联储措辞不变，表示ldquo；在较长时期内rdquo；，联邦基金利率将保持在ldquo；异常低的水平rdquo；，这是明智的，因为复苏尚不稳固，经济中存在巨大的闲置产能，当前通胀率处于低水平，通胀预期稳定。

The positive pressure of 6kPa was given via mask to the nasopharynx of the testee, while the control took normal breath.

被试者经面罩给予6kPa的鼻咽部正压，对照者正常呼吸，高压舱以0.5kPa／s的速率增压至5kPa，被试者和对照者均不采用其他任何主动或被动开放咽鼓管的措施，测鼓室腔压力；高压舱以同样速率增压至20kPa，被试者条件不变，对照者可进行主动或被动开放咽鼓管的措施，测鼓室压。

Invariant Manifold: An unstable periodic orbit in a Hamiltonian system (a general class of differential equations which includes the three body problem) have associated two families of orbits forming tubes connected to the periodic orbit.

不变流形：一个不稳定的周期轨道的哈密顿系统（一个微分方程一般类，其中包括三个体问题）有关联的两个形成连接管轨道周期轨道的家庭。

If the system is unstable, there will be no steady-state response, only a transient response.

如果系统是不稳定的，将没有不变的响应，只有一个暂态响应。

Theoretical analysis and experiment results all demonstrate that the new adaptive wavelet decomposition proposed in this dissertation not only be translation invariant but also scale invariant.

理论分析及实验结果都证实，本文提出的这种自适应小波多尺度分解不仅对信号的平移是不变的，而且对信号的尺度变换也具有不变性。

In this paper, we propose the translation-invariant contourlet-like transform with lower redundancy than both the nonsubsampled contourlet transform and the translation invariant contourlet transform.

本文提出了一种具有平移不变性的类轮廓波变换，其冗余度比非抽样轮廓波变换和平移不变轮廓波变换更低。

The advantages of this new method are:(1) The field conductivity distribution function is fitter the actual condition than tradition methods:(2) On the condition of triangle elements cut of field, making the calculation speed increase in large degree than tradition methods.

与单元电导率重建算法相比，节点电导率重建算法的优点有：(1)使场域电导率分布函数更符合实际情况，克服了传统算法中对电导率作离散化处理的缺陷；(2)当场域采用三角形单元剖分方式时，在场域的剖分密度保持不变的情况下，可以大大提高重建计算的速度；(3)在场域采用三角形单元剖分方式时，场域的剖分密度可以比以前加大一倍，在不降低重建计算速度的前提下，可以改善重建计算的精度；(4)由于重建的是所有节点的电导率，避免了先前单元电导率重建图像中"阶梯"状边缘和"锯齿"状边缘的出现，明显地改善了图像的视觉效果。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
