Moreover, the dopants with large molecule volume and high refractivity index will increase the Rayleigh scattering loss but improve the thermal stability of GI POF.

如果掺杂剂的分子体积大、分子折射率高，则GI POF预制棒的瑞利散射损耗大，但热稳定性能高。

Instrument testing, usually by polarizing instrument to test the structure of its crystals, through the refractometer to test its refractive index.

We put it across that the sign of nonlinear refractiveindex changes under certain conditions if the high-order excited state contributessignificantly to the refractive index.The nonlinearity changes from self-defocusing to self-focusing if the refrangibility of the ground state is larger thanthat of the first excited state and smaller than that of the second excited state.

高阶激发态折射度贡献较大时，非线性折射率符号在一定条件下存在转化：如果基态折射度大于低阶激发态的折射度而小于高阶激发态折射度，材料发生自散焦—自聚焦转化；如果基态折射度小于低阶激发态折射度大于高解阶激发态折射度则发生自聚焦—自散焦转化。

It was found that there is a maximum extreme value of HEPP birefringence to different draw ratio with increasing the refringence of various infiltrating me-dia.

结果发现随着介质折射率的增加，不同拉伸比的HEPP纤维的双折射变化都存在一个共同的极大值(η=1.54)。

In this case,the refringence of HEPP fiber iS equal to that of the medium (n=1.54),and Form Birefringence is equal to gero.

此时介质与纤维的折射率相等，微孔相结构对纤维双折射测定的影响完全消除，△form等于零。

The light scattering data were well described by the crossover model proposed by Anisimov and Sengers, and the effective critical exponentsγandυshowed nonmonotonic crossovers from the 3D-Ising values to the mean-field ones as the temperature departed from the critical point. The coexistence curves exhibited that the values of effective critical exponents for the order parameter of the refractive-index decreased as the distance from the critical point increased, however after the regular terms were subtracted, the nonmonotonic crossovers from Ising to mean-field critical behavior were exhibited. The influence of sodium bromide on the trend of the crossover was small.

静态光散射数据符合Sengers和Anismov等提出的临界跨接理论，关联长度和渗透压缩系数的有效临界指数存在非单调跨接，盐对于跨接程度的影响不明显；共存曲线研究发现，随着偏离临界温度，折射率的有效临界指数逐渐减小，但是当与共存曲线相关的正规项的影响被排除以后，体系表现出从3D-Ising到平均场行为的非单调跨接，盐对于跨接程度的影响不明显。
