It is helpful to understand more deeply the contents associated with the statically indeterminate structure, and know better the application of the unit load method.
这有助于更深地理解超静定结构相关内容，也可以进一步了解单位荷载法的应用。

Kilns are the key equipment in the production of metallurgy, cement and material of fire-fast. It is the statically indeterminate system with heavy load, large torque and multi-support.
回转窑是冶金、水泥、耐火材料连续生产中的关键设备，是一种重载、大扭矩、多支点、超静定运行系统。
