The nylon 66 / montmorillonite nanocomposites were prepared by the melt intercalation process . the nanostructure features were revealed by waxd and tem . most of the silicate layers were exfoliated into 10 - 100nm and randomly dispersed in the nylon 66 matrix 结果表明，硅酸盐片层在加工过程中被撑开，大部分蒙脱土以10 100nm厚度的片层分散于尼龙66基体中，形成了纳米复合材料。
The main results are as the following : ( 1 ) the microstructure of lamellae pearlite has evolved ultrafine cementite particles throughout the ferrite matrix uniformly after four passes . the ferrite matrix is homogeneous grains , and average grain size is - 0 . 3um 主要结果如下： ( 1 ) ecap变形四道次后，片层状的珠光体组织演变为了超细的渗碳体颗粒均匀分布于亚微晶铁素体基体的组织。
Exfloited nanocomposites were successfully synthesized . the study of melting compound about pet eva abs pvc cpe and montmorillonite has been carried out . we abtained several intercalated nanocomposites , tem shows the interlayer spacing is no more than 100nm 首次对pet 、 eva 、 abs 、 pvc 、 cpe 、 pp与蒙脱土熔融复合进行了研究，制得多种插层型纳米复合材料， tem照片显示：多数粘土片层的厚度在100nm以内。
The results show that small cr addition in steel can decrease the lamellar spacing of pearlite , and markedly increase strength and hardness with almost the same ductility and toughness , and accordingly improve wear and shelling - resistance of wheel steel 实验结果显示，加入微量的铬，可以细化珠光体的片层间距，在保持韧塑性基本不变的情况下，显著增加材料的强度和硬度，从而提高车轮钢的耐磨性和抗剥离性能。
The intercalating rate of modifier was 27 . 3wt % . fourier - trandformed infrared spectroscopy ( ft - ir ) also shows that modifier has been between layers . a series of polyamide / montmorillonite nanocomposites were prepared by melting extrusion method in two - screwed extruder at first 首次对三元尼龙和蒙脱土复合进行了研究， tem结果表明：粘土片层杂乱无章地分散在基体中，平均厚度10nm ，形成剥离型纳米复合材料。
While the 001 layer spacing of o - mmt , which was organized with 40 % dosage of na - mmt , was only 2 . 96nm . it indicated that htab and styrene had corporate effects on styrene intercalating o - mmt . ft - ir also testified that polystyrene had intercalated the layers of montmorillonite 而使用同等量htab处理na - mmt制得的o - mmt片层间距仅为2 . 96nm ，这说明在苯乙烯乳液聚合插层o - mmt时， htab与苯乙烯发生了协同作用。
2 . the structure of artificial vegetation in shapotou region the structure of vegetation usually consisted of a vertical structure and a horizontal structure of vegetation . based on the vertical structure of vegetation , there were three layers of artificial vegetation in shapotou region 2 、植被垂直结构及水平结构：沙坡头地区人工固沙植被垂直结构可分为三个显著的片层结构：灌木片层、草本片层和生物结皮片层。
Xrd results revealed that melt intercalation of compatibilizers into organo - mmt followed by blending with ldpe was preferred to the dispersion of the silicate layers in ldpe matrix . moreover , the dispersion of mmt was dependent on the interaction among organo - mmt , surfactants and compatibilizers 研究发现，该体系采用相容剂有机蒙脱土先复合再与基体熔融挤出的分步插层技术，可使硅酸盐片层达到很好的分散效果。
The results of tem showed that the layers of omt had been separated partly into alone fragment by in - situ polymerization of pu ; the agglomerative nano - sio2 particles in pu composite had been dispersed , but the disperse status became worse as the increase of its content Tem结果显示，通过pu的原位聚合，复合材料中omt的片层被部分分离成单独的片层;纳米510 :粒子被分散，但在复合材料中的分散状况随着其含量的增大而变差。
2 . the effect of nanometer montmorillonite on the nonisothermal crystallization behaviors of nylon 66 / montmorillonite nanocomposite were studied by dsc . nonisothetmal crystallization kinetics of nylon 66 / montmorillonite was studied using eopoxobckuu equation 通过dsc方法研究了蒙脱土纳米片层的存在对尼龙66非等温结晶行为的影响，应用非等温结晶的bopoxobcku方程，研究了尼龙66蒙脱土纳米复合材料非等温结晶动力学。
