【求助】几句英文请大家帮忙修改！

各位大侠： 文章里有几句话，觉得写得有点问题，请大家帮忙修改！ 1. However, crosslinks reduce the crystallinity degree (Xc) (in Table 2) simultaneously and hence increase the free volume, which would increase the segmental mobility in the amorphous domain. 然而，交联同时也使结晶度下降，相应的自由体积就变大了，这就使无定形区域的分子链的运动变得容易了。 2. The influence of the former may be exactly counteracted by that of the latter. Hence, the Tg does not undergo any visible changes. 前者的影响刚好被后者抵消。因此，Tg 几乎没有发生什么变化。 3. Thus, it can be concluded that appropriate feed of excess H is an effective and feasible approach to improve the mechanical properties 因此，我们可以得出结论投入适量过量的H是提高力学性能的一个有效可行的方法。 4. Simultaneously, as shown in Table 2, an increase in crosslink density accompanies with a reduction in Xc, which deteriorates the mechanical strengths but enhances the toughness. 同时，如表2所示， 交联密度的提高伴随着结晶度的下降，这就使力学强度变差，但是使韧性变好。 5. While the tensile strength and flexural modulus vary little when H increases from 1.2 to 1.3, resulting from the equal influence of crosslink density and Xc. 而H从1.2增至1.3时，拉伸强度和弯曲模量几乎没有发生什么变化，这是因为交联密度和结晶度对力学性能的影响程度相同。 |

1.第一句的原因结果弄反了吧，原因是后面的the free volume, which would increase the segmental mobility in the amorphous domain，结果是前面的reduce the crystallinity degree (Xc) (in Table 2) simultaneously。 2.The influence of the former happens to be counteracted by the latter one. Hence, there is no obvious change in the Tg value. 3.第三句还可以，没有问题。 4.accompaniis with 换成 is accompanied by 5.resulting from... 改成 which is due to the influence of crosslink density is roughly the same with that of Xc. 看看如何 |
