請大家?guī)兔π薷模?br />
中英文對照如下,以中文章為參考!英文感覺寫的不好!謝謝!在線等! 雖然PDA型均聚酰亞胺PI薄膜的拉伸強度(257.86 Mpa)和模量(2.20 Gpa)分別是CDA型均聚聚酰亞胺PI薄膜的2.4倍和1.6倍,但是,其延伸率卻比CDA型均聚聚酰亞胺PI1薄膜要小,而共聚物薄膜則很好地綜合了兩種均聚物的機械性能優(yōu)點。 The elongation value of PDA-type homo-PI film was lower than that of CDA-type one, whereas the tensile strength, 257.86 MPa, and modulus, 2.20 GPa were 2.4 and 1.6 times as those of ODA-type one, respectively.。。。。。。 [ Last edited by yongbinz on 2010-11-8 at 21:56 ] |

| Although the tensile strength (257.86 Mpa) and modulus (2.20 GPa) of the PDA-type homo-PI film are 2.4 and 1.6 times of those of the CDA-type one, respectively, its elongation value is lower than that of the CDA-type one. While the copolymer film well integrates the advantages of the two types of homopolyer in mechanical Properties . |
| Although the tensile strength (257.86 Mpa) and modulus (2.20 GPa) of the PDA-type homo-PI film are 2.4 and 1.6 times of those of the CDA-type one, respectively,the elongation value of the former is lower than that of the later. Furthermore, the copolymer film of PDA and CDA could integrate the excellent mechanical properties of those homo-polymers. |
