NBR/modified montmorillonite and NR/HMMT nanocomposites were prepared by the mixing intercalation method with the monomers resorcin and hexamethylenetetramine complex . XRD and TEM showed that the interlayer spacing of HMMT had got much larger with RH addition and the layers of HMMT had dispersed in rubber matrix on nanometers. FTIR and crosslinking density results explained that chemical reaction had occurred between RH and rubber in the course of vulcanization, which improved the crosslinking density of rubber and enhanced the interaction between the rubber and HMMT.

采用单体混炼插层法，引入间苯二酚-六次甲基四胺的络合物，制备了橡胶／改性蒙脱土插层纳米复合材料。X-射线衍射分析表明：RH的加入使蒙脱土层间距不断扩大；TEM观察到无机片层在橡胶基体中纳米级分散；FTIR和交联密度的分析发现，在硫化过程中RH与橡胶发生化学键合反应，同时与改性蒙脱土相互作用，使得体系交联密度提高。

The experiment that is just enunciation, the royal crown eject of water quantity ratio gold bullion many, elucidation royal crown of density ratio gold bullion of the density be small, this certificate the royal crown don't use pure gold manufacturing.

稀土掺杂金红石相TiO2的禁带宽度是其吸收波长的主要影响，进而决定其光催化活性。

The intensification phenomenon at 1-meter scale was not found. The larval density in water column might be highly heterogeneous even in very small scale. On the other hand, we consistently found higher settlement density in sand areas than in reef areas. This phenomenon may well have been caused by the intensification

本研究结果在1公尺的空间尺度下并没有发现附苗强化现象，但是礁区的附苗密度却如预期低於砂区，推测可能是1公尺空间尺度内幼生数量过於不均匀，相差5倍的附苗板面积不足以造成幼生附苗密度的变异，而礁区与砂区则由於面积相差相当大因此可以发现附苗强化现象。
