下面这句话，如何改的地道一点
|
| 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. |

(感谢奖赏) 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" 重复 值得写 "recent" 或 "more recent" 表示你一直关注科学新知 shrinkage, drying, and gel brittleness 皆为大规模,宏观性现象 (macroscopic phenomena),预计是无法量化学键强度时的好推理 (所以说是 "once blamed on" 怪老天不怪人培植晶体能力有限) 重复提 "of alkoxysilanes" 一则强调,二则提醒读者 |
