可见光

In visible light these galaxies are hidden by dust in IC 1805 and were unknown until 1968 when Paolo Maffei found them using infrared observations.

这些星系在可见光是由灰尘隐藏在IC 1805年，被不明，直到1968年，保罗马菲发现他们利用红外观测。

May issue a short-wave, medium wave, long wave UV and visible wavelengths of light radiation in four.

The photocatalytic degradation property of ZnM2O4 (M=Cr, Mn, Fe) nanoparticles was investigated by using methyl orange, acid red B and reactive red K-2G as model pollutants under the irradiation of a mercury-vapor lamp (λ＞400 nm) or sunlight. The degradation rates of the above three dyes by ZnM2O4(M=Cr, Mn, Fe) are over 80％, 57％ and 39％, respectively within 2 h. It is found that ZnM2O4 (M=Cr, Mn, Fe)has a novel photocatalytic behavior for dyes under visible light irradiation.

在高压汞灯(λ＞400 nm)和太阳光照射下，纳米ZnM2O4粉体对甲基橙、酸性红B、活性艳红K-2G等有机模拟降解液的2h脱色降解率分别达到80﹪，57﹪和39﹪以上，表明锌尖晶石ZnM2O4光催化剂具有良好的可见光催化活性，并随禁带宽度Eg的减小，催化活性增加。

While erthrocyte, hemoglobin and Hela cell were under oxidative damage induced by the hydrogen peroxide (H2O2) or tert-butyl hydroperoxide on different concentrations of dihydromyricetin, hemolysis rate of erythrocyte and methemoglobin converted from hemoglobin was estimated by ultraviolet-visible absorption spectroscopy. Whereas mmalondialdehyde from erythrocyte was measured by thiobarbituric acid colorimetry, the cellular viability of Hela cell was examined using MTT 3-(4, 5-dimethylthiazol-2-yl-2, 5-diphenyl tetrazolium bromide assay.

在不同的二氢杨梅素浓度下，用过氧化氢或过氧化特丁烷对红细胞、血红蛋白和Hela细胞进行氧化伤害，以紫外－可见光分光光度法检测红细胞溶血率和由正常血红蛋白生成的高铁血红蛋白，硫代巴比妥酸法测定红细胞中的丙二醛，MTT法检测Hela细胞的活力。

The photocatalytic degradation of phenol and methylene blue in aqueous solution is used as a probe to evaluate their photocatalytic activities.

以苯酚和丙酮的光催化降解作为探针反应，研究了它们在紫外和可见光下的光催化活性。

The visible absorption spectrograms of 32 jadeite jade samples were measured by MPV-Ⅲ microphotometer, and their three-impulse values were calculated.

采用MPV-Ⅲ型显微光度计测定了32个翡翠样品的可见光吸收光谱，计算了部分样品的三刺激值。

For light, this is on the scale of tens of thousandths of a millimetre.

建议：跟可见光波长类似，这种材料的规格达到了万分之一毫米。

This study attempted to extract lithlogical and mineralogical information in the arid region using the ASTER multispectral data.

本研究尝试利用ASTER 可见光近红外和短波红外的多光谱遥感数据提取干旱地区的岩石与矿物信息。

There are two types of black materials: one kind of them absorbs visible light through electron transition to form black, such as nigrosine, anthraquinone black, and iron oxide black, the other kind such as carbon black reflects and absorbs visible light several times with its superficial porous effect to form black.

现有黑色材料主要有两大类：一类是通过化学物质的外层电子吸收可见光跃迁来形成黑色，如苯胺黑、蒽醌黑、铁黑等；另一类则是利用材料表面的多孔结构，对光进行多次反射和吸收，形成黑色，如炭黑。

During the process of deriving percent vegetation cover using "Nondense Vegetation Model", Leaf Area Index is a necessary parameters, an improved method for deriving LAI from visible and near infrared measurements above a soil background is proposed.

在用"非密度模型"反演植被覆盖度的过程中，叶面积指数是一个必要的参数，本文提出了一种改进的借助可见光波段和近红外波段反射值来提取叶面积指数的方法。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
