反射率

The NN models for three-component retrieval based on in situ remote sensing reflectances have rather good results.

2基于现场遥感反射率水色三要素浓度反演的神经网络模型取得较好结果。

Also it is found that when the reflectivities of two antireflection and high-reflection coatings increase, and the stable oscillation of the master wave is established in the external cavity, the threshold current is the lowest, but the efficiency of the electro-optical conversion and the power of the output light reduce sharply.

并且发现当两端面的反射率增加，同时激射波长在外腔长度中形成稳定谐振时，激光器的阈值电流达到最小值，但相应的电光转换效率和出光功率会急剧地减小。

The variation of reflectivity spectra for the VCSELs with the change of incident angle, optical thickness of resonance cavity and optical thickness of DBR are investigated.

研究了VCSEL的反射率谱线位置随光线入射角度、谐振腔的光学厚度以及DBR光学厚度的变化。

The vitrinite reflection factor in source rocks Ro is 0.3-0.65%, a few up to 0.2%.

烃源岩中镜质体反射率R〓在0.3％-0.65％，个别可达0.8％。

This article mainly carries on the analysis with new weather radar data characteristic in this rainfall process. With the analysis of the reflection factor, the wind profile and the rainfall estimation, we know that the strong wind vertical change and sufficient water vapor condition have the extremely vital role to the development and the maintenance of the convection storm; The new weather radar has the very good instruction function to the weather forecast, specially at the rainfall estimated and in the catastrophe weather forecast and the short-time forecast.

本文主要对这次降水过程中的新一代天气雷达资料特征进行分析，通过对反射率因子、风廓线和降水估测等主要产品的分析，表明较强的风的垂直切变、充足的水汽条件对对流风暴的发展和维持有非常重要的作用；新一代天气雷达对气象预报工作有很好的指导作用，特别在降水估计、灾害性天气预报和短时临近预报中有非常重要的意义。

The reflecting power of the earth is primarily dictated by the proportion of cloud and snow cover.

地球的反射率主要是由云和雪覆盖的部分决定的。

"There is a clear need for more research into characterising the variability in albedo that currently exists between the different variants and strains of common crop plants," commented Ridgwell.

很显然，对于不同变种间，以及普通作物不同品系间，存在的不同反射率的特点需要更多研究，Ridgwell评论道。

Transmissions at 0.75 and 1.65 μm can also be used to retrieve τ and re. 2. Study the impact of cloud inhomogeneity on the satellite retrieval simultaneously. Two 3D cloud fields, cumulus and stratocumulus fields are used in our study. The two cloud fields are generated with LES model and are adopted by the I3RC phase II. The BRDF at the wavelengths of 0.65 and 2.13 μm are calculated with SHDOM, and then the cloud optical thickness and effective particle radius are simultaneously retrieved using the MODIS algorithm. We studied the impact of cloud inhomogeneity on the satellite retrieval at high and medium resolutions. Some conclusions have been made, such as the BRDF abnormal phenomenon, the reverse relationship between τ and re, the clustering effect of over and under estimation in the retrieval of τ and re .

我们选用为I3RC所采用的由LES模式给出的具有明确物理属性的两个高分辨率三维云场－积云场与层积云场，利用SHDOM三维辐射传输模式来模拟卫星观测的辐射值，并采用MODIS算法进行反演，同时研究了在高分辨云场及中低分辨率云场下，云的非均匀性对反演云光学厚度及有效粒子半径的影响，并得到了云的非均匀性会造成的双向反射率异常，反演结果中光学厚度与有效粒子半径的负相关关系，高估或低估现象是成&簇&出现的等结论。

By simulating the natural conditions and building up a database of backscattering coefficient and emissivities using IEM model, it is found that when ratio of rms height and correlation length is in some certain range, the ratio of backscattering coefficient to reflectivity is linear or polynomial with surface roughness.

分析所建立的数据库后，得出在0.2＜均方根高度＜1.7，均方根坡度＜0.2和2.0＜均方根高度＜4.0，0.2＜均方根坡度＜0.4两种情况下后向散射系数与反射率之比与土中国科学院遥感应用研究所博卜学位论文壤粗糙度的关系。

A fiber grating is used for output of resonant cavity with 60% reflectivity.

反射率为60%的光纤光栅用作光纤激光器谐振腔的输出，3dB带宽为016nm。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
