英语翻译
After pressing ,many of zhe powder particles touch one another .during the initial sintering stage ,neck form along the contact regions between adjacent particles ,in addition,a grain boundary forms within each neck ,and every interstice between particles becoms a pore.As sintering progresses,the pores become smaller and more spherical in shape.The driving force for sintering is the reduction in total particle surface area;surface energies are larger in magnitude than grain boundary energies.Sintering is carried out below the melting temperature so that a liquid phase is normally not present.Mass transport necessary to effect the changes is accomplished by atomic diffusion from the bulk particles to the neck regions.

挤压之后,很多的粉状颗粒彼此接触,在初步的煅烧的过程中,形成在相邻的颗粒间产生细长的接触面.同时,颗粒晶体就会在细长接触面中形成 ,细小的裂缝中就会形成气孔.再进一步煅烧过程中,气孔就会形成越来越小的球状气泡.煅烧的作用在于减少整个颗粒表面的气泡. 颗粒表面的张力要大于颗粒间的引力.煅烧的过程温度要低于融化的温度以确保不含有液态物质.由较大颗粒的分子扩散到细长的接触面是呈批量的形式而形成此变化.
