However, there are still many difficulties in mass production of qualified preform of paper-based friction material using manual sheet-making apparatus. So a semiautomatic sheet-making apparatus was designed to make an improvement.
借鉴于造纸工艺的碳纤维增强纸基摩擦材料预制体成型工艺——“抄片”，成为保证预制体增强纤维、摩擦性能调节剂和填料在预制体中均匀分布的重要一环。

随着造孔剂含量的增加，预制体气孔率升高。
The porosity of preforms increased with the increase of starch contents.
你应该使用预制体的原因是改变一个预制体，所有的实例都改变了。
The reason why you should use prefabs is that when a prefab change, all the instances change too.
使用链接代替–有场景需要预制体被分配，当实例被创建时，确保已经分配好了。
Use links instead – have a field thatrequires a prefab to be assigned and make sure to assign it when instance is created.
