Under the condition that the maximum index change at the core-cladding interface and absorption coefficient were constant, the numerical results indicated that the reflectivity of cross-mode coupling peak between LP_ 01 and LP_ 11 modes varies parabolically with the saturation length of index change.

仿真结果表明，在纤芯和包层边界的最大光致折射率变化量和纤芯吸收因子不变的情况下，随着纤芯折射率变化的饱和长度的增大，LP01和LP11模间的互耦合反射峰呈抛物线形变化，当饱和长度增大到一定值后，互耦合反射峰随饱和长度的增大而逐渐减小并最终消失；同阶LP模的自耦合反射峰随饱和长度的增大而增大。

Composites with organophilic montmorillonite have been prepared by adding oMMT to interpenetrating polymer networks of polyurethane and epoxy resin, which had been prepared by a sequential polymeric technique.

采用原位插层聚合与聚合物互穿技术相结合，制备了有机蒙脱土改性的聚氨酯／环氧树脂互穿网络复合材料。

Both surfactants can intercalate into the layers of the pristine clay dispersed in water prior to polymerization. Although the d spacing of the POSS-intercalated clay is relatively smaller than that of the CPC-intercalated clay, PS more easily intercalates and exfoliates the POSS-treated clay than the CPC-treated clay.

插层剂预先插层到分散於水中的黏土后再进行乳化聚合反应，虽然POSS插层后黏土的层间距离较CPC插层后的层间距离小，但聚苯乙烯与POSS互容性较佳，所以易使黏土达到脱层结构，而CPC则反之。

渤海湾潮滩海岸从海河口以南到黄河三角洲北缘的大口河以北，据野外调查发现，这里的潮间浅滩具有明显的分带性，从岸向海可以分为四带，即龟裂带、内淤积带、滩面冲刷带、外淤积带，相应各带的沉积物为：淤泥与粘土质淤泥、淤泥、粉砂与淤泥互层、粗粉砂。

The effects of electroplated Ni layer and electroless plated Ni-P layer on the diffusion behavior in Sn-Ag/Cu solder joint were studied. The results by EPMA analysis showed that the electroless plated Ni-P layer acted as a good diffusion barrier between Sn-Ag solder and Cu substrate. However, the electroplated Ni layer can not hinder the inter-diffusion and reaction between molten Sn-Ag solder and Cu substrate when reflowing, and there was a layer of IMC (Cu6Sn5) at interface of Sn-Ag/C u solder joint.
