Endothelium-derived nitric oxide plays an important role in the regulation of vasomotion and the balance between thrombosis and thrombolysis.

血管内皮细胞产生的一氧化氮(nitric oxide，NO)在调节血管舒缩、维持凝血—溶栓平衡方面扮演着重要的角色。

Later on, hydration of fly ash, slag and gypsum produces gel material enwrapping the surface of ettringite, which increases the strength of H50-6s hardened paste on the one hand, and hold back ettringite weathering on the other hand. So ettringite decomposition is effectively controlled so as to avoid strength decrease of the hardened paste.

这样，凝胶物质一方面使硬化浆体的强度缓慢增加，另一方面阻缓了大气对钙矾石的侵蚀，有效抑制了由于钙矾石的分解而导致硬化浆体的强度倒缩。
