氰化钙

Adopting this craft to produce the inferior gold potassium of cyaniding,it is reliable that the craft is simple,the production process is easy to control,but the dependence on raw materials of quality of the products is strong.

其中氰化亚金具有极大的现实意义：一方面，钠、钾、钙的金氰络盐是易溶化合物，它们可以通过在空气中氧的参与下溶于相应的氰化物中而制得，这是氰化法从矿石中提金的基础；另一方面，金的氰化物在高科技领域中的应用日益广泛。

Application of calcium peroxide has become wider and wider.It was not only used in the fields of rice direct sowing,edible fungus production,soil improvement,aquiculture,wastewater treatment,chemical production,and air purification etc.,but also it has been used as food and feed additive,fruit and vegetable preservative,assisting agent for gold extraction by cyanidation and so on.

过氧化钙可用于水稻直播、食用菌生产、土壤改良、水产养殖、污水处理、化工生产与空气净化等领域，可用作食品和饲料添加剂、水果和蔬菜保鲜剂、氰化法提金助剂等，有着越来越广泛的用途。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
