The first liquid crystal material has birefraction index approximately equal to one half of that of the second liquid crystal material.

其中，第液晶材料层射率约略等于第二液晶材料层射率半。

On the basis of the refraction principle of soluble solid, the content of the soluble saltless solid in soy sauce was determined by refractometry.

基于可溶性固形物射原理,用光计法测定酱油中可溶性无盐固形物含量,取得了与重量法基本致结果。

During this alignment, each crystal can act like a miniature lens, refracting sunlight into our view and creating phenomena like parhelia, the technical term for sundogs.

在这个平面内，每个冰晶就像个小透镜样，将太阳光射入我们视野，造成幻日现象，其术语就是幻日。

The researcher selects students’ discourse as a tiny cut to dialyze its cultural back, namely the student’s culture, to exposit the true appearance of school cultural ecosystem.

研究者选取了学话语这微观层面来力图透视其背后所射文化蕴意，即学文化，从而揭示学校文化实然状。

Using the characteristic of refractive index are smaller than 1 in the reststrahlen band,we can produce photonic crystal having forbidden band in the middle infrared and far infrared.

由此可知利用材料在剩余射线带内射率小于1特性，我们可以制备出中红外区和远红外区存在禁带光子晶体。

The colour that metal of popular this year future feels, like scarab there is La Youzi to carry refrangible fingernail oil like housing special cruel become reconciled looks.

2．今年流行未来金属感色彩，像金龟子壳般有蓝有紫带射性指甲油非常酷和好看。

Incorporating array of metallic wires into the host media, such as ferrimagnet YIG under an external magnetic bias field, is a novel method to synthesize negative refractive index (NRI) material.

摘要以亚铁磁煤质-YIG为基体，在其中嵌入金属导体线阵列是人工合成负射率微波媒质种新方法。
