金属纳米微粒的热力学性能不仅依赖于纳米微粒的尺寸，还依赖于纳米微粒的形状。

The thermodynamic properties of metallic nanoparticles not only depend on the particle size, but al - so depend on the particle shape.

通过引入描述纳米微粒形状效应的形状因子，建立了金属纳米微粒尺寸形状效应的结合能函数与熔化温度函数。

By introducing a shape factor, the functions on cohesive energy and melting temperature are developed which can describe thee effect of size and shape of metallic nanoparticles.
