偏光

For many years Polarized Lenses have been available, but only available with a limited selection of colors or tints.

多年来偏光镜片虽然可以买得到，但是这些镜片的颜色及色调却很有限。

The results showed that the highest absorbency of copolymer was 2 260 for distilled water in optimized conditions. FTIR and microscope analysis demonstrated that the copolymer has trinary network structure.

The influence of reaction conditions on the absorbency was discussed.

研究了反应条件对产品吸水率的影响，利用傅里叶红外光谱、X射线衍射、偏光显微镜对接枝共聚物进行表征。

Di(3,4-dimethyl)benzylidene xylitol as synthesized in the lab from 3,4-dimethyl benzaldehyde and xylitol, and a series of polypropylene samples were prepared based on the amount of the nucleating agent, DMDBX used.

以3，4-二甲基苯甲醛和木糖醇为原料合成1，3-2，4-二（3，4-二甲基）亚苄基木糖醇，将DMDBX作为成核剂使用溶液沉淀法制备DMDBX质量分数分别为0、0.1%、0.3%、0.5%、0.7%、0.9%的聚丙烯样品，采用红外光谱仪、差示扫描量热仪、X射线衍射仪和偏光显微镜等方法，研究了DMDBX对PP结晶结构和结晶性能的影响。

The conoscopic interference pattern of wafer with optical axis parallel to the surface of a crystal is sensitive to the crystal birefractive index.

光轴平行表面的晶片的会聚偏光干涉对晶体的双折射率非常敏感。

Polarizing microscopy and differential scanning calorimetry were used to study the effect of carbon fiber on the crystallization of polypropylene.

本文用偏光显微镜和示差扫描量热计方法研究了碛纤维对聚丙烯结晶行为的影响。

Their thermotropic phase behavior was investigated by differential scanning calorimetry and POM. It was found that T(subscript S-N) w and T(subscript N-I), of PMMAZO was slightly increased with the increased of the mass ratio of liquid crystal block segments. PEO and PMMA block affected the liquid cystal behavior of PMMAZO. Meanwhile, PMMA and PMMAZO obviously influenced the crystals property of PEO segments3 which was decreased as the increase of molecular weight of PMMA and PMMAZO segments.

以差示扫描量热仪和偏光显徽镜研究了ABC三嵌段共聚物PEO-b-PMMA-b-PMMAZO的热力学相转变行为，发现随着PMMAZO链段的质量百分比的增加，三嵌段共聚物中PMMAZO链段的T和T逐渐提高；同时，PMMA和PMMAZO链段的长短影响PEO链段的结晶性，随着液晶段PMMAZO和PMMA链段分子量的增加，PEO链段的结晶性减弱。

The phase transition and states of the lyotropic liquid crystals of chitosan in dichloroacetic acid were studied by polarized microscopy.

借助偏光显微镜研究了不同壳聚糖样品在二氯乙酸中的液晶相转变和液晶状态。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
