膨胀性

The main objective of this thesis is to investigate the formation and properties of negative thermal expansion glass-ceramics containing β-eucryptite. The effects of composition modification (SiO2 content, the kinds and amount of nucleation agents, excess Li2O) on CTE were also examined.

在锂铝矽酸盐(lithium aluminosilicate，Li2O-Al2O3-SiO2，简称LAS)系统中的固溶体β–eucryptite相具有负热膨胀系数，其与正膨胀性的精密元件复合，可藉由应力补偿，控制该元件的尺寸变化，以防性质变异。

The strength reduction and the deformation incensement of supporting layer of the bases after saturated should be studied.

更多饱水后的强度降低率和变形增加率，当存在淤泥、软土、膨胀性土、湿陷性黄土等不良土层时，应进行相应的勘察试验工作。

The safety of the existing buildings should be decided based on the loading of the building, the foundation type as well as the buried depth of the foundation. The strength reduction and the deformation incensement of supporting layer of the bases after saturated should be studied. The corresponded investigations and tests should be carried out when silt, soft soil, expansive soil and collapsed loess et al exist in the bases.

对于现有建筑物的安全，要根据建筑物荷载、基础类型和砌置深度分类进行评价，研究了解地基持力层在饱水后的强度降低率和变形增加率，当存在淤泥、软土、膨胀性土、湿陷性黄土等不良土层时，应进行相应的勘察试验工作。
