4) spheroidal crystal
球形晶体
1.
According to the cr ys tallography condition of spheroidal crystal,it is required that the crystallite must have a large number of small angle branches which are distributing radiall y and symmetrically;besides,these small angle branches should have the feature of"regular branch"that means they have same growing babit and growing rate.

5) spherical quasi-crystal
球形准晶
1.
With the increase of Y the number of quasi-crystals substantially increases; in a certain range Mn accelerate the spherical quasi-crystals\' formation, while when exceeds a certain amount, conversely it inhibits the formation of quasi-crystals.

补充资料：Assembly晶粒封装
以树酯或陶瓷材料，将晶粒包在其中，以达到保护晶粒，隔绝环境污染的目的，而此一连串的加工过程，即称为晶粒封装（assembly）。封装的材料不同，其封装的作法亦不同，本公司几乎都是以树酯材料作晶粒的封装，制程包括：芯片切割→晶粒目检→晶粒上「架」（导线架，即lead frame）→焊线→模压封装→稳定烘烤（使树酯物性稳定）→切框、弯脚成型→脚沾锡→盖印→完成。以树酯为材料之ic，通常用于消费性产品，如计算机、计算器，而以陶瓷作封装材料之ic，属于高性赖度之组件，通常用于飞弹、火箭等较精密的产品上。
