We find that the scattering process of the charge and lattice defect is different under different strengths of electric field and the interchain coupling interactions.(1) The results of the dynamics of oppositely charged polarons in polymer chains show that:①At a weak field (.1 mV/A), they finally scatter into an entity, which will be dissociated as a pair of neutral solitons after their first collision and separation.

1聚合物中极化子对的非弹性散射对电场强度的依赖关系表明：在弱场(小于0.1mV/A)时，电荷由于量子隧穿相互抵消，但不改变符号，极化子晶格碰撞后带着剩余的电荷返回，但是它们不能分得很远，在电场作用下，可进行第二次碰撞，结合成一个整体，然后又分成一对中性的孤子对。

Finally, lots of experiments are made and the results indicate that automatic recognition of the gauge is reliable to recognise gauge value and has the certain application value.Automatic recognition of the gauge by the machine vision technology not only reduces the intesity of labor but also increases the precision of reading gauge. The application of machine vision technology promotes level in the precision measurement.

The effect factors analysis based on FEM shows that: Raising the strength of concrete and the thickness of cover concrete would delay the cracking of concrete; Stress superposition would appear due to the influence of adjacent rebar, and increasing the rebar space would postpone the time of cover cracking; Stirrup could suppress the cracking of cover concrete, however, the effect is limited and the corrosion-degree-ratio and corrosion expansive force would not increase until the cover concrete cracking happens completely.

结合有限元分析结果，对影响锈胀开裂的各因素进行了分析，结果表明：提高混凝土强度、增加保护层厚度有助于延缓保护层的开裂；相邻钢筋的存在会使钢筋之间的混凝土出现应力叠加现象，箍筋对混凝土保护层内由锈胀产生的应力具有抑制作用，但是在保护层完全开裂之前，箍筋的抑制作用有限。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.
