| 1. | Nano - caco _ ( 3 ) only affects blends " degree of crystallization , but do not affect the crystallization structure 一caco3只对树脂体系的结晶度有轻微的影响,不影响晶体的结构。 |
| 2. | While adding ydh151 to this system , the torque decreased and the melting temperature and the degree of crystallization of the matrix increased 而对于hdpe基体, mmt的加入并没有影响体系的熔融温度和结晶度。 |
| 3. | With the carrier gas flux rising , the film ' s thickness and the degree of crystallization increase . the band gap decreased little , and the photocatalysed efficiency was enhanced 随着载气流量的增加,薄膜的厚度增加,结晶性能提高,光学带隙变窄,光催化效率增加,亲水性没有明显变化。 |
| 4. | The extent of grafting was analyzed by ftir and element analysis and thermal properties of hdpe - g - ydh151 were studied by dsc measurement . when adding dcp to hdpe , the melting temperature and the degree of crystallization of the matrix decreased because of the crosslinking reaction of hdpe 而且mmt的加入,降低了hdpe - g - aa的熔融温度和结晶度,这主要是因为剥离后的mmt在一定范围内限制了pe链的运动,从而降低了基体的结晶能力。 |
| 5. | It is the especial congregate structure of polymer matrix that is necessary for the forming of three - dimensional interpenetrate network between the polymer and copper . the mma unites lead to the advantage of improving fiexibity of the film , destroying the formal arrangement of macromolecule chain in polymer and decreasing the degree of crystallization . the ita unites help the solvolyzed copper ion transfer in the film and benefite the forming and establishment of the networks of polymer matrix 聚合物基体特殊的聚集态结构是互穿立体网络形成的必要条件,皿m的加入有利于破坏丙烯睹大分子链的规整性,使结晶度降低,提高聚合物的柔韧性,含亲水基团的单体( ita 、 as )存在有利于降低离子迁移的界面能,提供溶剂化铜离子迁移的途径以及聚合物基体网络结构的形成和稳定。 |
| 6. | Consequently , with increasing mmt content , the tensile strength and young ' s modulus of hdpe - g - aa / mmt nanocomposites increased , while that of hdpe / mmt composites decreased . moreover , the addition of mmt to hdpe - g - aa decreased the melting temperature and the degree of crystallization of the matrix . these changes may be attributed to high interfacial adhesion between hdpe - g - aa matrix and exfoliated clay , which reduces the mobility of crystallizable pe chain segments , and subsequently reduces the crystallization ability 研究结果表明: mmt在hdpe中不能达到纳米级分散,而在hdpe - g - aa中, mmt能以插层型利剥离型的结构存在,这主要是由于极性的丙烯酸接枝在hdpe上提高了后者的极性,而且能与mmt上的活性基团进行化学反应,从而提高了pe链进入mmt层间的可能性,使mmt在基体中达到纳米级分散。 |
| 7. | The growth temperature affects greatly the yield , morphology and degree of crystallization order of the cnx nanotubes . cnx nanotube with " bamboo - like " structure grow preferentially when fe ( c5h5 ) 2 or fe powder are used as catalyst . it is noted that the cnx nanotubes grown on fe ( c5h5 ) 2 catalyst have the best well - distributed " bamboo - like " structure 随制备温度的升高, cn _ x纳米管的产量、形貌结构及结晶有序度会发生变化,二茂铁以及铁粉对“竹节状”结构cn _ x纳米管的生长有明显催化作用,二茂铁催化产物的结构均匀性最好, “竹节”结构最规则。 |
| 8. | At the same time , it was indicated that the improved separating properties of membranes that had been marinated in methanol was pertinent to the degree of crystallization of polymer chains in membrane . also the effect of temperature and solvent mixtures on the performance of ca - eva composite membrane was related with reciprocity of polymer chains in membrane 同时,指出ca膜溶剂浸泡后处理效应与膜内大分子链的结晶程度相关,此外,还从膜内大分子链之间的相互作用解释了ca eva复合膜中的溶剂效应和温度效应。 |
| 9. | The films prepared under 425 ? is composed with amorphous snoi and its sheet resistance is very high . with the substrate temperature ' s increasing , the degree of crystallization , film thickness increase and electrical resistivity , sheet resistance decrease obviously . when the substrate temperature is higher than 525 ? , the temperature ' s increasing is not of benefit to the films thickness and sheet resistance 常压热分解cvd法制备的sno _ 2在较低基板温度下制备出的薄膜基本上是非晶态的,方块电阻很高;随着基板温度的升高,薄膜厚度增加,薄膜结晶程度提高,薄膜电阻率和方块电阻均显著降低;当基板温度高于525以后,随着基板温度的升高,薄膜厚度基本不再明显增加,薄膜结晶程度继续提高,薄膜电阻率继续降低,方块电阻不再明显降低。 |
