However, this flexibility brings a great deal of inconvenience to shape design for typical demand of design is not only qualitative but also quantitative, such as a global smooth and fair surface approximating a group of scattered points and interpolating a section curve .

但这种灵活性也给形状设计带来许多不便：典型的设计要求既是定量的又是定性的，如"逼近一组散乱点且插值于一条截面线的整体光顺又美光的曲面"。

The transparent dielectric film has a refractive index selected to be in a range of from 1.30 to 1.46, both inclusively, with respect to the wavelength of incident light and has an optical film thickness selected to be in a range of from 0.20 lambda to 0.38 lambda , both inclusively, when lambda is the wavelength of incident light.

相对入射光的波长而言，透明绝缘膜的折射率被选定在1.30至1.46范围内，且包含此二值在内，光学膜的厚度被选定在0.20λ和0.38λ的范围内，且包含此二值在内，这里的λ是入射光的波长。

The reporter vectors which contain the luciferase gene and dioxin response elements are then transfected to different cell lines. When used together with a sensitive luminometer, the cells express different light intensity depending on their dioxin concentrations.

针对此传递路径的特色，我们建立两个含有戴奥辛识别单元和萤光基因的表达质体，分别送入不同的细胞株中，藉由萤光的定量做出一组标准曲线图，使其成为侦测环境污染物的工具。

When there is no trailing of the minor planet image (or you are measuring the middle of a trail) the time of observation is the mid-exposure time. If you are measuring both ends of a trail, then one end is associated with the start of the exposure, the other with the end.

如果你测量的是小行星拖线的中部或该小行星没有明显的拖线，那么你应该使用你暴光时间的中点时刻作为该测量点对应时刻，如果你既测量了起点又测量了终点，那么你应该分别对应的是暴光的起始时间和终了时间。

They are able to do this by using the femtosecond laser once again to alter the surface of metal and create unique nano- and micro-scale structures on the metal.

他们控制纳米结构的大小和形状，从而控制那些结构吸收和放射的光的颜色，来改变金属纤维放射的每种光的波长量。

Ants relive as a spirit carrier in Chen's hand, but their real concrete images and personate symbolization in human world make this group of works possess strong cultural pertinence.

尽管蚂蚁在陈志光的手中仍然是作为一个精神载体而复活的，但蚂蚁真实而具体的形象，尤其是它在人的世界里所已有的拟人化象征，却使陈志光的这批作品具有了强烈的文化针对性。

Its intensity reduction and traveling distance limitation are discussed. This new kind of experimental method based on the characteristic of a polarized light is presented.

最后根据以上的研究，讨论了在实际云雾介质中的成像场合下，消除蛇形光的影响，改善信噪比提高光在云雾中的成像质量的方法。

By the means of experiments and numerical simulations, it is verified that speckles can be formed when nanofluids are illuminated by laser beam. First, clear speckles are formed by illuminating static nanofluids containing proper volume fraction of nanoparticles. Then, classic-scattering-model and photon-nanoparticle-collision-model are respectively established based on the wave-particle duality of light. The formation of speckles with nanofluids is simulated respectively on these two models, and the formation mechanism of speckles is figured out.

其中通过静态实验确定激光照射含有合适体积百分比纳米粒子的纳米流体可以形成清晰的散斑图；基于光的波粒二象性，分别根据光的波动性和粒子性建立了"经典散射模型"和"光子——粒子随机碰撞模型"，基于这两个模型分别对激光照射纳米流体形成散斑的过程进行了数值模拟，并对散斑的形成机理进行了解释。

The model of the received power is established based on the basic principles of geometry optics and radiometry. This model provides the principle of receiver-transmitter design and performance evaluation. On the basis of the received power model and APD noise model, the response of measurement signal after passed through the frequency difference circuit and the corresponding change of its SNR are studied.

研究了非合作目标测距时，发射视场与接收视场的重叠情况，以及视场重叠区域内光的探测情况，并以此为基础，根据几何光学和光度学的基本理论，建立了非合作目标测距中接收光功率的数学模型，为接收/发射器的结构设计，以及测距性能的预测提供了理论依据。

The blue color is caused not only by Rigel's blue color but because the dust grains reflect blue light more efficiently than red.

女巫头星云的颜色是蓝色的，这不只是因为参宿七是蓝色的，而且也是因为星际尘埃的颗粒，对蓝光的散射效率比红光要好。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
