摘　　要：本文根据超微颗粒的晶化特征分析和阐明了梯温场中发生定向晶化的机制。指出了这种方法不仅与温度梯度有关而且与升温速度有关，并揭示了它在实际应用中的可能性。In this paper On basis of behaviour of crystallization of ultromicro particle the mechamism forforming orienterational crystallite in temperature gradient have be analysed and explained. The degree andlength /radius ratio of the orienteration of crystallite are depnded not only on the degree of gradiet oftemperature hut. also on the rate of rising temperature and there is great pctentiol of application.
