不可见光

As a result, if the iridescence is produced by thin-film interference, not only the thickness of lamellar structure must be defined within a certain nanometer, but also the refractive index need to be different between lamellar structure. In other words, the chemical composition, refractive index and thickness of exsolution lamellae need form to trinity, such as labradorite, albite, andradite and orthoamphibole. If the iridescent color is produced by grating-diffraction, the lamellar structure just needs to be arrayed regularly, the spacing of the edges of lamellar structure needs to be regular and narrow, but not necessarily within the range of the wavelength of visible light, such as shell of abalone, pearl and opal.

薄膜干涉式晕彩不仅要求宝石内部结构层的厚度必须在一定的纳米范围内，而且结构层内部的折射率也必须有所差别，也即，当结构层由两相组分出溶而成，其化学成分、折射率和结构层厚度形成三位一体时，符合薄膜干涉式晕彩，如拉长石、钠长石、石榴石和角闪石；而光栅式衍射晕彩则仅要求结构层排列规则，边缘狭窄但不需要窄到可见光波长范围内，能使入射光的振幅或位相，或两者同时产生周期性空间调制的结构即可，如鲍贝壳、珍珠和欧泊。

According to the calculated proportion of aniline and dye, if the other reaction condition is maintained, and the proportion in electrolyte is changed, the DS-PAn film with different sensation properties can be obtained, i. e. absorption range and intensity in visible spectrum can be controlled by the proportion of aniline and dye.

实验证实，可以通过预先计算苯胺与染料的比例，在电解液中改变苯胺与染料的比例，保持其他电化学反应条件不变的情况下，在经过一定时间反应后，可在多种衬底上生成不同增感效果的DS-PAn薄膜，同时此薄膜在可见光区的吸收谱带的宽度和强度可由聚苯胺与染料的比例来控制。

However its large band gap energy limits its practical application in the case of natural solar light.

而阻碍其应用的是它的大禁带宽度不能有效地利用太阳光，因此研究开发对可见光响应的二氧化钛就成为当前光催化别研究中的关键课题。

Among the forms of energy that fall into this "extrasensory" category that humans cannot directly detect are chemical energy, gravitational energy, nuclear energy, and forms of energy similar to visible light.

一些人类不可以直接感受到的能量形式，我们把它列入超能量的范围去，包括有化学能、重力能、原子能、和那些类似于可见光的能量。

In this paper, a new product of Ce/ TiO2 compound antibacterial agent has been made, comparing with naked nano－TiO2, it has better antimicrobial activity against E.coli ,S.aureus and scorch gemmule bacillus in the solar light, increasing the quantity of Ce4+, exhibiting stronger antibacterial property.

制备出稀土铈掺杂锐钛型纳米TiO2复合抗菌功能材料，该抗菌材料与不掺杂的纳米TiO2相比，在可见光下对大肠杆菌、金黄色葡萄球菌、枯草芽孢杆菌的混合菌具有较好的抑菌效果，随着Ce4+的摩尔浓度增加，制备的试样的抗菌能力越强。

Doping Cr into perfect TiO2 (110) surface can create the new active surface state different from that of oxygen defect surface ,AM and transition metals deposited TiO2 (110) surface. Its active surface state is the Cr 3d occupied state near EF and the value of band-gap drop from 3.13eV to 1.16eV, so photocatalysis reaction can perform in visual light area after doping Cr into perfect TiO2 (110) surface.

TiO_2(110)面掺杂Cr 可以产生不同于氧缺陷、碱金属及过渡金属负载的新表面态，其表面态为靠近E_F 的Cr3d 电子占据能带，带隙由原来的3.13ev 降至1.16eV，因此，掺Cr 后TiO_2 可在可见光区发生光催化作用。

Unfortunately, 80% of it is opaque—at least to light.

不幸的是，它八成的部分是不透明的，至少对可见光是这样。

It is the phosphor coating, not the mercury vapour itself, that produces the fluorescence effect—and hence the visible light.

是被覆的磷而不是汞蒸气，产生荧光现象——和可见光。

This invisible barcode adelomorphic mediators and special paper by photochemcal clutured, cannot open, can only be used for a one-time use, does not recognize the human eye, and neither does a visible light photography, photocopying of imitation, which can be used only when a certain wavelength of the reading of the bar code scanner information, at the same time this scanner for General black and white bar codes also compatible.

这种隐形条码隐形介质与纸张通过特殊光化学处理后融为一体，不能剥开，仅能供一次性使用，人眼不能识别，也不能用可见光照相、复印仿制，辨别时只能用发射出一定波长的扫描器识读条码内的信息，同时这种扫描器对通用的黑白条码也兼容。

These specific absorption bands are in relation to the special energy levels.

人们经过十多年的时间，对钛酸盐纳米管的组成、形成机理和物理化学性能进行了大量的研究，但是到目前为止，研究者对其形成机理、可见光吸收等特殊光电性质的来源、结构稳定性等方面的认识尚不清楚，因此本论文对这些方面开展了如下研究：在第二章中我们从热力学的角度系统地研究了煅烧温度对钛酸盐纳米管形貌、结构稳定性和光学性能的影响，发现钛酸钠纳米管是热力学稳定的，而钛酸纳米管是热力学不稳定的。

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。
