封闭时间 meaning in English

confinement time

Compared with the experiment data , the temperature field and the thermal stress field are discussed . the spacing , the time of sealing and the plane form of the later joint - filled slots are discussed especially , and it is found that the spacing , the time of sealing and the plane form of the later joint - filled slots are comprehensive indexes which are relevant to material , design and construction . the theory value of the spacing and the time sealing of the later joint - filled slots and some proposals on the plane form are presented on the basis of numerical calculation
本文在综合前辈的研究成果的基础上，推导了粘弹性场的三维有限元解，对比实际工程实验数据，对大体积混凝土结构内部的温度场和应力场进行了分项研究，重点讨论了后浇带的留置间距、封闭时间和平面形状，发现其留置间距、封闭时间和平面形状都是综合指标，是和材料、设计、施工有关的。
