In order to radically improve the present silicothermic reduction process for magnesium smelting, this paper started with the idea of taking liquid calcium as reductant and studied the feasibility of the new magnesium reduction process deoxidizing by liquid calcium .

为了从根本上改进现行的硅热法炼镁工艺，从新的还原剂——液态钙着手，研究了用液态钙为还原剂的金属镁还原新工艺的可行性。

Experimentally, stores can be emptied by increasing of InsP3 molecule in the cytosol, dialyzing the cytoplasm to high concentrations of Ca(superscript 2+) chelators such as EGTA or BAPTA, or treating with the endoplasmic/sarcoplasmic reticulum Ca(superscript 2+) ATPase inhibitors like thapsigargin and cyclopiazonic acid.

尽管这个领域受到愈来愈多的重视，然而，钙池调控钙离子通道所能影响的细胞生理意义或其调控机制，至今所知仍然非常有限。

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。
