| 1. | The high oh / al ratio and large amounts of al - pillaring solution favored the basal spacing and thermal stability of al - plms
在此基础上，笔者对al - plms进行了掺杂和改性的研究。 |
| 2. | X - ray diffraction studies revealed the formation of intercalation nanocomposite with the change of the peak corresponding to the basal spacing of the pure mmt
采用xrd和tem研究了纳米复合材料的形态，结果表明，蒙脱土的晶面间距继续增大，形成了纳米复合材料。 |
| 3. | In the thesis , organic - montmorillonite ( org - mmt ) was obtained by an ion - exchange reaction between ca - montmorillonite ( ca - mmt ) and alkylammonium ion , leading to increase the basal spacing of montmorillonite
本文采用烷基季铵盐对ca基蒙脱土进行有机化处理，使其成为有机蒙脱土( org - mmt ) 。 |
| 4. | The result shows that dmso were intercalated into the interlayer of kaolinite and basal spacing was swelled from 0 . 715nm to 1 . 110nm , so the kaolinite - organic matter intercalation compound was formed
结果表明，二甲基亚砜进入了高岭土的层间，层间距由0 . 715nm增加到1 . 110nm ，形成高岭土有机插层材料。 |
| 5. | The mechanica1 performance is superior to p1ain pp . 0n the sem photographs of impact fracture surface , it was observed that the pu11out of si licate 1ayers hard1y was found and the compat ibi 1 ity of pp and montmori l 1oni te was improved great l y . xrd resu1 ts suggested that the basal spacing of silicate layer was about 4
小角xrd结果显示，复合材料中无机片层间距d _ ( 001 )在4 . 0nm左右，为插层型材料，通过dsc测试发现复合材料的熔点和分解温度均有一定的提高，蒙脱土的加入可提高材料的热性能。 |
| 6. | In this thesis , organic - montmorillorite ( org - mmt ) was obtained - by an ion - exchange reaction between na + - montmorillorite ( na + - mmt ) and alkyl ammonium bromide , leading to increase the basal spacing of montmorillonite . xrd analysis indicated that alkylammonium ions had already exchanged with na + ions in na - montmorillonite and long alkyl - chains had entered into the gallery of montmorillorite
X -射线衍射( xrd )分析结果表明有机胺阳离子已同蒙脱土中的钠阳离子发生离子交换作用，烷基长链进入蒙脱土层间，导致层间距扩大，并使蒙脱土层间亲水性转变成亲油性。 |
| 7. | By means of a1c13 hydrolyzing in naoh solution , the author prepared al - plms which were characterized by xrd , xrf , ft - ir , sem etc . some factors in the experiments were studied in detail . the result showed that the concentration of a1c13 , naoh , al - pillaring solution did n ' t affect the basal spacing and thermal stability of al - plms greatly
笔者采用alcl _ 3在naoh溶液中水解的方法制备了铝柱撑蒙脱石，并利用xrd 、 xrf 、 ft - ir 、 sem 、 n _ 2吸附?脱附等手段对制得的样品进行了表征，系统讨论了各实验因素的影响。 |
| 8. | The results was explained with the scattering theory of spherical particles , which indicated that the effect of morphology of composites on the transparency mainly came from the exfoliation extent of amt , which caused the change of the particle size and basal spacing of amt in epoxy matrix , and the effect of the particle size was more significant than the basal spacing of amt
对剥离型纳米复合材料的透光率与有机土含量及波长的关系进行了进一步的研究得出，材料的归一化透光率与有机土含量及波长存在下列经验关系：并采用球型粒子光散射模型对上述实验结果进行了理论分析。 |
