1·Last, the temperature contraction coefficient and dry shrinkage coefficient of porous concrete are advanced.

得出多孔混凝土的温缩系数和干缩系数。

2·The max temperature shrinkage coefficient 28 days and 60 days is smaller than common lime-fly ash aggregate.

聚丙烯纤维加固二灰碎石的28天及60天的最大温缩系数均小于素二灰碎石的温缩系数。

3·It was shown that dry shrinkage and shrinkage coefficient of specimens decreased if partial cement was replaced by fly ash and slag, and then further by more fly ash.

结果表明，用矿渣和粉煤灰取代部分水泥，随后又增加粉煤灰的比例，可以连续降低固化土的干缩应变和干缩系数。

4·The research shows that fly ash could restrain early autogenous shrinkage by changing the parameter of binder, such as hydrated velocity, creep coefficient, elastic modulus and so on.

研究表明：粉煤灰通过改变胶凝材料体系水化速度、徐变系数、弹性模量，可以有效抑制早期混凝土的自收缩。

5·The two kinds of materials are connected together by macro-molecular nylon pieces, which eliminate the problem of the coefficient difference of shrinkage of wood and metal.

两种材料通过高分子尼龙件连接，解决了木材和金属收缩系数不同的问题。

6·The shrinkage factor for de-specking is estimated with the neighboring reference contourlet coefficient in every sub bands.

然后用每个系数的邻域系数通过估计其去斑收缩因子来实现系数的自适应收缩；
