The absorption spectrum center wavelength of dolomite is near 232 μm is shorter than 235 μm of limestone,and thus RBD7 and RBD8 can be employed effectively to identify dolomite and limestone,respectively. Felsic rocks show AlOH and Fe3+ absorption characteristics in the VNIRSWIR region,while the maficultramafic rocks show Fe2+ and Fe,MgOH absorption features,hence the use of different valence state of iron and secondary minerals can distinguish them:ASTER band2/band1 represent Fe3+ distribution,ASTER band2/band1 represent the Fe2+ distribution,RBD6 can estimate the AlOH mineral abundance. Psammitic/pelitic schist containing phengite,chlorite,stilpnomelane,as well as the weathered surface covered by clay minerals,exist characteristic absorption spectrum in the 221 μm(band 6),and has a high reflectance in 165 μm(band 4),while the blueschist/greenschist show high reflectance in the 221 μm(band 6),and it exit low reflectance in 165 μm(band 4),and blueschist/greenschist appear low ASTER band4/band6 ratio.

白云岩的CO2-3吸收谱带中心波长位于232〖KG*3〗μm，与灰岩的CO2-3 吸收谱带中心波长位置235 μm相比，具有向短波长方向移动的特点，据此可以利用RBD7、RBD8分别有效的识别白云岩和灰岩；长英质岩石显示AlOH和Fe3+ VNIRSWIR吸收特征，而基性超基性岩石显示Fe2+和Fe、MgOH特征，利用不同的铁价态和次要矿物可以区分它们：ASTER band2/band1代表了含Fe3+矿物分布信息、ASTER band5/band4代表了含Fe2+矿物分布信息、RBD6可以估计AlOH矿物的丰度；砂质/泥质片岩含较多的多硅白云母、绿泥石、黑硬绿泥石以及风化后表面覆盖的其它粘土矿物，在221 μm（band 6）存在有特征的吸收谱带，并且在165 μm（band 4）具有较高的反射率，而蓝片/绿片岩在221 μm（band 6）反射率较高，不具有明显特征吸收谱带，同时其在165 μm（band 4）反射率较低，因此蓝片/绿片岩ASTER band4/band6 比值低。

In 1991, Spacemen 3 split into two groups, Spectrum and Spiritualized; the latter took the opposite musical approach from its parent group, fleshing out the space rock sound into lush, caressing, orchestrated epics that made them arguably the style's most popular band.

在1991年的时候，Spacemen 3 分裂成了两支乐队：Spectrum 和 Spiritualized；其中后者采取了和原乐队完全相反的音乐手法，他们丰富了太空摇滚的声音，使得它更加豪华、轻柔、像管弦乐一般宏大，而这一切最终使他们成为了这种风格中最受欢迎的一支乐队。

As a result,the flame spectrum of the whole wave-band and the image corresponding to every flame spectrum data were obtained in the experiments.

Admiral Sir Alan West, Adm Band's predecessor as Chief of Naval Staff and First Sea Lord, was public in his opinion that this level is too small to meet the full spectrum of taskings, noting that the figure of 25 was based on analysis of high-intensity warfighting tasks alone and did not address wider maritime security needs, or make any allowance for attrition.

Band元帅的前任Alan West元帅在他出版的书中发表了自己的观点，即如此小规模的舰队根本不足以胜任所有的任务，他还指出25这一数字是基于单单应付一场高强度战斗的考虑而没有提及应对更为繁杂的海事安全需求或是解决海上小冲突这类事件的需要。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
