在低强度电磁振荡条件下，凝固组织细化和等轴晶化的原因是：电磁振荡力对金属初生晶的周期性拉伸、压缩、剪切、折弯、扭转等机械作用，使其出现断裂和剥落，增加形核数量；电磁振荡的局部搅拌作用使固/液界面前沿的温度和成分趋于均匀化，导致梯度降低，抑制了柱状晶的生长。

他们似乎是分阶段进行，接着，又-再次开始，但感觉更深一步。

The pigment of Berberis heteropoda Schrenk is a type of anchocyanin and it is strong in resistance against light and to some extent, good in enduring heat and low consistence oxide. But it is poor in resistance against reductant and preservative. It can be applied to the condition of PH. It is also found that sucrose and most of metal ions do not exert negative effects on the stability of the pigment, except Fe3+, Fe2+and low consistence Pb2+, which have some extent effects. Adding stability matter can improve its stability. The harm trace elements contains are within requirement of the National Standard on food safety, As the lexicological study indicates that the pigment does not have any toxicity and mutagenesis, it can be used as edible pigment.

结果表明：大孔树脂吸附-解吸附法纯化黑果小檗色素实验室工艺简单易行，色素回收率高；黑果小檗色素属于花色苷类色素；耐光性好；对热有一定耐受性；对低浓度氧化剂有一定耐受性；耐还原性差；对防腐剂耐性差；适用PH＜6条件下使用；蔗糖和大多数金属离子对色素无不良影响，但Fe~(3+)、Fe~(2+)、Sn~(2+)和低浓度pb~(2+)对色素有影响，加入稳定剂后，可提高色素的耐热性、耐氧化性、耐防腐剂能力；经对有害微量元素进行检测和毒理试验表明，该色素安全无毒，可以作为天然食用色素使用。

The rheological properties of 500SN and hexadecane thin films were investigated with the improved surface force apparatus.
