Then the carbon nanotubes were purified by calcined in a suitable temperature after the acid - treatment . before the calcined process , tga was used to determine the calcined temperature 对制得的碳纳米管进行了纯化，纯化中先对碳纳米管产物进行了酸处理，然后在适宜的温度下煅烧。
Mdsc and tga results showed that the terpolymer exhibited an extremely high glass transition temperature and decomposition temperature when compared to the copolymer from po and co2 结果表明这些三元共聚物具有较高的分子量，且玻璃化转变温度随着主链上的环己撑碳酸酯含量增加而逐渐升高。
The glass powder size , morphology and mechanical properties of glass / epoxy composites were measured by means of laser particle size analyzer , sem , material testing machine and tga respectively 利用激光粒度分析仪、电子多功能实验机、 sem 、热分析仪等刚试粉料粒径、结构形貌以及机械强度等性能。
A 54 year - old male had been diagnosed with modified tga at age 40 , but no surgery was performed . enhanced multislice ct revealed the ascending aorta coursing left of the anterior pulmonary trunk 一名54岁男性患者在40岁时诊断出矫正性大动脉转位，当时未行手术。增强多层螺旋ct成像显示升主动脉位于肺动脉前壁左侧
However , the measurement of tga and dsc showed that the thermal stability of the nanocomposites had improved a lot and the crystal speed had also have a slight improvement 但是， tga和dsc分析结果显示：聚乙烯蒙脱土纳米复合材料相对于纯聚乙烯来说，热稳定性有较大幅度提高，同时，复合材料的结晶速度也稍有增加。
As the content of the expanded vermiculite was 20 % , the tonset of the polybenzoxazine ( mulitphenol type ) / vermiculite hybrid nanocomposites from its tga cure was 35 chigher than that of the polybenzoxazine ( mulitphenol type ) / phlogopite composites 膨胀蛙石含量为20时，插层纳米固化物的起始热分解温度高于金云母的约35t 。
The modification of ommt has greatly affected the thermogravimetric analyses ( tga ) curves and vicat softening point ( vsp ) temperature of the materials . the addition of ammo - mmt could improve the composites thermal stability and vsp temperature 从整体上看， ammo - mmt使复合材料的热稳定性好于纯pvc ，并且使材料的维卡软化点提高。
The cured products had lower cure - degree and even lower cross - linking density . the weight loss at the second peak ( 300c ~ 550c ) of dtga was 64 % , but the weight loss of polybenzoxazine ( bisphenol a type ) itself was only 8 . 5 % Tga分析：固化物在第二微分失重峰( 300 550 )处迅速失重64 ，没有第三失重峰，而在此处树脂失重仅8 . 5 。
Results of dsc and tga showed that thermal properties of psmn were better than ps . psmn was melt - mixed with resin mixture in which polypropylene was the main component and polypropylene - montmorillonite nanocomposites were prepared 将制备出的psmn母料与以聚丙烯( pp )为主体的树脂基体进行熔融共混，制备出聚丙烯蒙脱土纳米复合材料( ppmn ) 。
Up / montmorillonite nanocomposites was prepared by in situ intercalation polymerization . its microstructure was characterized by tga , xrd and tem . the results show that the up / montmorillonite nanocomposites is intercalated nanocomposites 通过tga 、 xrd和tem等手段表征不饱和聚酯蒙脱土纳米复合材料的微观结构，确定为插层型纳米复合材料。
