The function and design way of TLL is briefly introduced, and safe interlock is realized in furnace of distillation device.

简单介绍了TLL的功能和设计方法，以及在蒸馏装置加热炉安全联锁中的应用。

The ferric sulphate solution was used for trickling the acid-cured uranium ore and the residual leaching reaction incomplete in TLL process can be improved in this process.

该法采用硫酸高铁溶液淋滤熟化矿石，完成了薄层浸出法所不能完成的残余浸出反应。
