下面這句話，如何改的地道一點(diǎn)
|
| The poor chemical affinity between calcite and the silica molecules formed after hydrolysis and condensation of alkoxysilanes and the tendency to crack during shrinkage and drying due to the gel brittleness have been responsible for several studies with the objective of modifying and improving alkoxysilane performance. |

| Several studies with the objective of modifying and improving alkoxysilane performance have proved that two factors have impact on the final performance: the poor chemical affinity between calcite and the silica molecules that is formed after hydrolysis and condensation of alkoxysilanes and the tendency to crack during shrinkage and drying due to the gel brittleness. |

(感謝獎(jiǎng)賞) Cracking once blamed on shrinkage, drying, and gel brittleness of alkoxysilanes is, according to several more recent (performance) studies, caused by weakness of calcite-silica bonds formed during the hydrolysis and condensation of alkoxysilanes 所有研究都旨在提高或改善性能, 不需 "with the objective of modifying and improving performance" 重復(fù) 值得寫 "recent" 或 "more recent" 表示你一直關(guān)注科學(xué)新知 shrinkage, drying, and gel brittleness 皆為大規(guī)模,宏觀性現(xiàn)象 (macroscopic phenomena),預(yù)計(jì)是無(wú)法量化學(xué)鍵強(qiáng)度時(shí)的好推理 (所以說(shuō)是 "once blamed on" 怪老天不怪人培植晶體能力有限) 重復(fù)提 "of alkoxysilanes" 一則強(qiáng)調(diào),二則提醒讀者 |
