[交流] 帮忙翻译一段话

很明显,空白二氧化硅在0度到800度区间内没有明显的失重。而从树脂中分离的二氧化硅在该温度区间有较大的失重,约为35%。分离出的二氧化硅经索式提取后,在该温度区间内仍有约10%的失重,这说明,分离出的二氧化硅上包覆着许多的大分子,有物理包覆也有化学包覆,但经索式提取后,仍有失重,则表明有少量大分子化学包覆与二氧化硅上。

Obviously, there is no significant weightlessness from 0 to 800 centigrate for blank silicon dioxide. However, there exists a weightlessness of 35% for the silicon dioxide detached from resin at this temperature zone. Even after the extraction of silicon dioxide, there is still of 10% weightlessness. That is to say, the detached silicon dioxide is covered by lots of macro molecules, both in physical and chemical ways. Moreover, the weightlessness after extraction indicates there are still a few macro molecules chemically covered in silicon dioxide.
