If you look at longer wavelengths, into the infrared part of the spectrum, the absorption bands are from particular molecules.

如果你看看波长更长，到红外光谱的一部分，该吸收带是由特殊的分子。

If we make full use of the mid-infrared spectral features(i.e.,Christiansen Frequency features and reststrahlen bands),we could determine anorthite,olivine,quartz and alkali feldspar on the lunar surface successfully,which could not be accomplished by VIS-NIR spectra.

如果充分利用月球表面硅酸盐的红外光谱特征，即CF特征和Reststrahlen吸收带，将可以用于探测VIS-NIR光谱无法完成的探测目标：钙长石、橄榄石、石英和碱性长石等。

The results show that the glass-ceramics with fibroid structure is produced after definite heat treatment, the main crystallization phase is hedenbergite and anorthite is the minor crystallization phase. The optimal process of heat treatment shows as follows: the nucleation temperature is 850 ℃ and hold time is 100 min, and the crystallization temperature is 980 ℃ and hold time is 80 min. With increasing heat treatment temperature, the FT-IR absorption bands appear obvious split, the aluminum-oxide polyhedron in the glass network changes from [AlO4] to [AlO6]. The titanium ion in the glass network gradually transforms to the 6-coordinated, moreover forms minicrystal of MgTi2O5 and Fe2TiO4 which provides the position of heterogeneous nucleation for the growth of crystal.

结果表明：在一定的热处理条件下可以以基础玻璃制备出主晶相为钙铁透辉石，次晶相为钙长石的纤维状结构的微晶玻璃；最佳的热处理工艺为：850 ℃核化100 min，980 ℃晶化80 min；随着热处理温度的升高，红外吸收带发生明显的分裂；玻璃结构中的[AlO4]向[AlO6]转化；网络结构中的钛离子逐渐转变为六配位，形成微晶相——钛酸镁和钛铁晶石，为晶体的生长提供非均匀形核位置。

The absorption bands in visible region are related to photoinduced electron transfer processes, and the dimethylfluorenyl amino benzofuran groups are major chromophore thatcontributed to the sensitization of photo-to-current conversion.

可见区的吸收带都与光诱导电荷转移过程有关，二甲基芴氨基苯并呋喃基团是在光电转换敏化中起主要作用的基团。

The mid-infrared spectra of silicates show obvious Christiansen Frequency features and reststrahlen bands which are related to the composition of silicates.

硅酸盐矿物的中红外光谱一般具有明显的CF特征和Reststrahlen吸收带，这些特征都与硅酸盐的组成密切相关，可以作为判别其组成的指示特征。

In '51, they patented front and rear crumple zones.

而在 51 年，他们的前后冲撞吸收带获得了专利。

For the aqueous luminol solution, three absorption bands with maximum. adsorption wavelength λ max 220.7、294 4 and 351.5nm respectively have been detected, with the exception of a little hyperchromic effect, the absorption spectrum contour of the solution cavitated by an ultrasound with a frequency of 1.45 MHz has been certificated to be unchanged.

luminol水溶液的吸收光谱有3个吸收带，它们的最大吸收波长分别是220.7nm、294.4nm和351.4nm，超声空化作用后主要呈弱增色效应，但其吸收光谱的基本形状无明显变化。luminol-NaOH水溶液经超声空化作用后也有较弱的增色效应和减色效应，但不论是否经历超声空化作用，其吸收光谱都与luminol水溶液的吸收光谱相似。

The absorption bandedge redshifts were discussed in terms of Rayleigh scattering. The intensity decrease was caused by nonradiation energy transfer and transform between Co nanopticles and AAO template or metal nanoparticles absorb photon.

分析认为，光吸收带边红移主要是Co纳米粒子瑞利散射引起的消光现象；强度的减弱是由于沉积在AAO模板中的Co纳米粒子和模板之间发生了非辐射能量的传递和转换，或金属纳米粒子对光子具有吸收和传导作用所致。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
