摘要
在分形理论基础上,通过引入3个分形指数D_f D_s和α,导出一个较为适用的超微粒熔点公式.该公式表明:超微粒熔点不仅依赖于它的粒径,而且还要依赖于对它的制备方法.
On the basis of fractal-theory, and by the introducing of three fractal-exponents, I. e. Df Da and a, a practical melting formula of ultrafine particles is derived. It is shown that the melting point of ultrafine particles not only depends on the size of particles, but also on the preparing methods of ultrafine particles.
