红移

The study indicates that the center wavelength of FBG's reflected spectrum on the two polarization directions shift, and the reflectivity decreased with the increase of the twist angle. The longer wavelength produces"red shift". The shorter wavelength produces"blue shift". And the wavelength shift is basically same.

研究表明，随着扭转角度的增加，两个偏振方向的光栅反射谱中心波长发生移动且反射率降低，长波长的产生&红移&，短波长的产生&蓝移&，移动的波长量基本相同。

Wheares under buffer pH5.2, there is no strong static electricity and instead being a longer wavelength movement; SDS\'s participation just restricts the relative movement of heme\'s ethylene; a new fluorescent peak forms and the reduction of enzymatic activity is due to the packing of micella\'s formation.

强变性的阴离子表活剂SDS与带净正电荷和弱负电荷的SBP(处于pH2.6和4.2缓冲液中)有强烈的静电力作用，酶活力丧失，二级结构变化，荧光强度增加，特征Soret发生蓝移，卟啉环的π-π*共轭的分裂能增大；而当SBP带净负电荷(pH5.2)时，没有静电吸引力，Soret带发生红移；SDS的引入只是限制了血红素上乙烯取代基的运动，使其与卟啉环共轭：极性环境的变化导致产生新的荧光峰；酶活力因胶团包裹作用而有下降。

If the star is moving towards us its spectrum is blueshifted, and redshifted correspondingly when it moves away from us.

当恒星向我们运动时，其光谱将蓝移；反之将红移。

It would cause the scene above and below you to appear redshifted , or dimmer, and the light around your waist to become blueshifted, or very bright, Hamilton said.

这个力量会让你上方和下方的景象似乎出现红移，或者说变得更暗；你腰部的光会出现蓝移，或者说变得很亮。

The theoretical results show that,compared to the source spectrum,the normalized spectrum in some points of the diffracted field is blueshifted,and in the other points of the diffracted field the normalized spectrum is redshifted.

理论研究结果表明：部分相干光谱经单缝衍射后，在衍射光场的某些点，光谱相对于光源的光谱往短波方向移动，即为蓝移；而在衍射光场的另一些点，光谱呈现红移。

In the above all-sky map from the COBE satellite, radiation in the Earth's direction of motion appears blueshifted and hence hotter, while radiation on the opposite side of the sky is redshifted and colder.

在COBE卫星的全天微波背景辐射图上，向地球发来的背景辐射表现出蓝移，而背向地球而去的背景辐射表现为红移。

More recently, singular optics has been extended to polychromatic cases by Professor Wolf and his co-workers, in which they have showed that drastic spectral changes occur in the vicinity of intensity zeros in the focal region of polychromatic, spatially coherent, converging spherical waves, i.e. the spectrum is redshifted at some points, blueshifted at some other points, and is split into two peaks elsewhere.

最近，Wolf教授和他的同事们指出：在多色空间相干会聚球面波焦点区域振幅等于零的点附近会发生剧烈的光谱变化，即在一些点处光谱为红移，在另一些点处光谱为蓝移，在其它点处光谱则分裂为双峰结构。

The shape of star formation rate density versus the redshift in the closed box is quite similar to the Madau plot drawn from the UV luminosity in the observation of high redshift.

我们在星系化学演化的研究中发现：变化的IMF形式对星系化学演化结果有明显的影响；星系化学演化总趋势是随时间演化气体含量逐渐减少，金属含量逐渐增加；在我们所取的简单星系模型内部恒星生成率密度随红移的演化关系能够在一定程度上体现高红移观测中所得到的Madau图的特性。

Using density functional theory, the adsorption of cyanide on the different sites of Cu(100) surface was studied with end-on and side-on geometries.

采用密度泛函方法，以原子簇Cu14 为模拟表面，对CN自由基分子在垂直和平行Cu( 10 0 )表面不同位置的吸附情况进行了研究，结果表明：通过原子C垂直吸附在表面的顶位是其最佳吸附方式，吸附后CN键振动频率发生蓝移；而其它吸附方式中CN键振动频率均发生红移。

The speeds of cars are far too small for us to notice any redshift or blueshift.

再次以汽车为例子，汽车的速度太小了以至于我们很少注意它的红移和蓝移。

Do not gum up the work by telling mother what we are going to do .

别告诉母亲我们要干的事，那会把事情搞糟的。

In recent years, application of the partial prestressed concrete beam s is developed.

近年来，随着部分预应力砼梁应用的推广，发现我国规范所采用的名义拉应力法的计算结果不稳定。
