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

The results showed that the main crystal phase texture and distribution, the grain shape and size, pore and glass phase is the main factor that affect the mechanical strength of the material.
结果表明，晶相组成与分布、晶粒形状与尺寸、气孔及玻璃相是影响铝质电瓷材料强度的主要因素。
