The model of programmed crystallization of SPM was proposed based on the moment transformation of the population considering the agglomeration. The optimal temperature-time curves in a batch crystallizer which maximized the terminal mean size and mean weight size can be determined from the application of the Pontryagin Maximum Principle. The calculated crystallization results heating under optimal temperature were compared with ones under linear or natural heating temperature.

After that, the important equation for calculating reverberation time is given based on the definition of reverberation time and least squares method. Finally, we use our new method to calculate reverberation time in a rectangular enclosure; we also compare our results with those given by experiment and Sabine's equation. The comparison shows that the new method is more effective and accurate than Sabine's equation in calculating reverberation time of small enclosures.

The change of average size of products along the radius at the exist of reactor has also been calculated. The calculated results indicate that the residence time is longer, the average size of products is larger, but the distribution of size is narrower, tending to self-preserving distribution; when the concentrations of reactants increase, the average size of products becomes larger, but the distribution of size becomes narrower; the gradients of reactants are greater, the average size is larger; the increasing of reacting temperature will cause the size of product to be larger under same residence time. The average size of product at the exist of reactor varies along the radius, has a maxim value.

模型计算结果表明，产物粒度随停留时间的增加而增大，但粒度分布变窄，趋向自保分布；产物粒度随反应物进料浓度的增加而增大，粒度分布随进料浓度的增大而减小；反应器中反应物浓度梯度较大（相当于化学反应为快反应）时，相同停留时间下所得到的产物平均粒度增加；反应温度的增加，粒子平均粒径增加，粒度分布变窄；反应器出口处粒子平均粒径，随着与对称轴的距离的增加，有一极大值，先增加，后减小。

In order to verify the prediction efficiency, 27 interplanetary shock events from January 1979 to June 1982 and 68 interplanetary shock events from February 1997 to January 2000 are used for testing. Comparing the results of our disturbance model to those obtained by STOA and ISPM, we find that our disturbance model is as good as the other two models, and in some cases even better.

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。
