Furthermore the effects of tower top pressure, temperatures of tower top and bottom, reflux ratio on product purity were analyzed.

同时探讨了塔顶压强、塔顶和塔釜温度、回流比变化对产品纯度的影响，获得了试验条件下的最佳操作条件。

Using the method of top pressure and out soil promoted a comprehensive rectifying deviation to the structure, and using of steel pipe pile method reinforced the base of the tower.

建于深厚软土上的某铁塔因基础周边不均匀填土后产生了严重的不均匀沉降，经采用顶压法和掏土法对构筑物进行综合促沉纠偏，同时采用钢管桩法加固处理，实践表明效果良好。
