As the excess coefficient of reducing agent increasing, the percent reduction of strontia increases, but the tendency of increasing is more and more weak.

但是，在实际生产中还应该考虑原材料的价格、设备的使用率等因素对氧化锶的还原率和经济效益的多方面影响，才能具体确定最佳工艺条件。

With the raw material and the particle size of reducing agent narrowed, the percent reduction of strontia increases.(6) With the barbecuing pressure increasing, the percent reduction of strontia increases, after the certain value, the percent reduction of strontia decreases instead.(7) With reduction temperature increasing, the percent reduction of strontia increases.(8) The percent reduction of strontia is increasing with prolonging reduction time. In this experimental condition, it will become steady after 2.5h.

通过实验研究确定以SrCl_2-SrF_2-SrCO_3的纯锶盐体系作为电解质，实验中还采用了我们最新研制的熔盐电解监控仪对电解过程进行测量和系统的研究，得出以下结论：(1)增加电流强度，反电动势亦随之增加，而升高温度反电动势则有所降低；(2)随着电流密度的升高和电解时间的延长，电流效率逐渐增加，达到峰值后稳步下降；(3)延长电解时间，合金中锶的含量逐渐增加，最高可达18.1％；(4)开始电解后，反电动势逐渐增加，但向熔体中加入SrCO_3后，反电动势明显降低，因此认为在正常电解时是SrCO_3在分解。

The adsorption of strontium on the polyantimonic acid adsorbent was studied.

Kelp: Kelp alginic acid can slow down the rate of intestinal absorption of radioactive strontium, so that strontium excreted, and therefore has a role in the prevention of leukemia.

海带：海带中的褐藻酸能减慢肠道吸收放射性元素锶的速度，使锶排出体外，因而具有预防白血病的作用。

This is attributed to the infuence of the difference in carbonate mineralogy in different sedimentary environments on the Sr distribution and also to the diagenetic environment which depends upon the sedimentary environment.

究其原因，一方面因不同沉积环境中碳酸盐矿物组分不同，影响了锶的分布；另一方面与沉积环境所决定的成岩环境有关。

4TiO3 ceramics were prepared through a novel Sol-Gel process using the low cost carbonates as a substitute of acetates.
