Precious master of unrepayable kindness, PEMA ledrel tsal, remain as the crown ornament on the top of my head, I pray! 大恩之师龙青巴尊者,如同我心中皇冠之顶的珍宝,我向您祈求!
Finally the pentad sequences of atactic PEMA were calculated based on the discussion mentioned above. 最后计算了无规PEMA的五元组立构序列分布。
In this article the chain structure of PEMA was studied by 1H-NMR, 13C-NMR and COSY spectroscopy. 本文用~1H-NMR,~(13)C-NMR和化学位移相关谱(COSY)研究了聚甲基丙烯酸乙酯(PEMA)的链结构。
Polyurethane/ SiO_2 Nano-composite and Its IPNs Prepared by in situ Polymerization Study on Dynamic Mechanical Properties ofPS/ PnBA/ PEMA IPN 聚氨酯/纳米SiO2原位复合互贯网络材料研究PS/PnBA/PEMA三元互贯网络聚合物(IPN)的合成及动态力学性能的研究
Some difficulties in recognition of the spectra of PEMA come from the overlap of proton peaks. The assignment of the peaks in spectra of PEMA was discussed deeply with information provided from H-H COSY and C-H COSY spectra. 虽然质子峰的重叠给谱的识别带来一些困难,但是利用H-Hcosy和C-Hcosy提供的信息讨论了PEMA的~1H谱和~(13)C谱中各谱峰的归属。
Synthesis and Characterization of PEMA Brush Grafting from Crosslinked PS Microsphere 交联PS微球表面PEMA刷子的合成与表征
Poly ( butadiene styrene)/ poly ( ethyl methacrylate) graft copolymers ( SBR g PEMA) were synthesized by seeded emulsion polymerization and blended with high impact polystyrene ( HIPS). 采用种子乳液聚合法合成了丁苯橡胶接枝聚甲基丙烯酸乙酯共聚物(SBR-g-PEMA)。
The results showed that the sound absorption coefficient of the materials exhibited a higher value in its glass transition region due to the more sound energy lost by converting it into the heat energy. 结果表明,在玻璃化转变区域材料的吸声系数较高,PEMA和PVC均具有特征吸收频率。
The result indicated that excellent intercalation effect can be obtained by using PEMA as compatibility. 结果表明:采用马来酸酐接枝聚乙烯(PEMA)作为相容剂可获得较好插层效果;
Establishment of Mathematic Model of Passive Electromagnetic Armor and Simulation on the Experienced Force 利用电磁学的理论建立了被动电磁装甲(PEMA)数学计算模型;被动电磁装甲数学建模及其受力仿真
The results of tension tests show that tensile strength of the LIPNs increases with increasing the contents of PEMA and DAAM-ADH. 拉伸实验结果表明,增加硬组分和交联剂的含量,拉伸强度显著增加。
