This paper describes characteristics of montmorillonite interlayer water and factors affecting the swelling with hydration and the contraction with dehydration.
本文回顾了蒙脱石层间水性质、层间水化膨胀和脱水收缩的影响因素,提出蒙脱石层间的固溶体特征,在总结蒙脱石脱水作用与地面沉降关系研究成果的基础上,提出了用蒙脱石脱水作用研究地面沉降的思路。
The results show that the strengthening effectes in and between laminates increase along with prolonging of aging time at 150℃, leading to the increase of strength and the decrease of the plasticity of the alloy.
150℃时效过程中,延长时效时间可加强层内与层间两种强化机制的作用,从而使合金强度升高,塑性下降。
In order to solve the problems of serious interlayer interference and low productivity of low pressure layer in heterogeneous reservoir multilayer commingled well, the research of separate-layer oil production technology with constant displacement is carried out.
