Background, Motivation and Objective Concrete is a classic viscoelastic material, damping mechanism of which are affected greatly by viscoelastic properties. The viscoelasticity of the material is one of the mechanical properties of the damping mechanism. The elasticity of the material can cause the attenuation and scattering of the ultrasonic, the viscosity can cause the loss of energy. The static and dynamic viscoelastic are two different evaluation methods for the viscoelastic concrete material, respectively. The concrete is in a dynamic external pressure environment, so the dynamic mechanical properties compared with the static mechanical properties can reflect the performance of concrete in service. Statement of Contribution/Methods The paper presents the method for solving the ultrasonic attenuation coefficient, phase velocity and loss tangent value in the concrete according to the basic theory of viscoelastic properties, air-coupled ultrasonic testing and using loss angle tangent value as the evaluation parameter. The evaluation results of concrete dynamic viscoelastic are provided. Results The deformation, loss tangent increases and the proportion of the loss modulus increases with increasing of damage the concrete inside, but storage modulus decreased. Discussion and Conclusions The viscoelastic parameters of the concrete can be obtained;the change of concrete internal damage is monitored using the air coupling penetration method. Both of the concrete viscoelastic and concrete damage are considered, which provides a new method for concrete nondestructive.

在薄膜晶体管液晶显示器线路检测中,常通过对线路中的导电薄膜粒子的计数和定位实现其导电性的自动检测。为了解决窄边框线路中粒子密度增大带来的粒子重叠问题,提出一种采用微分干涉成像和掩模法结合k均值聚类的算法,在分离出粒子的亮、暗部后,结合图像熵值和粒子的凸性准确分割出粒子。讨论了聚类簇选值的影响,通过不同粒子密度、不同粒子尺寸的样本检验本文算法,并与以往的梯度结合灰度的方法进行对比。结果表明:本文算法在粒子密度较小的区域能达到92.6%的识别率,在粒子密度较大的区域也能达到86%的识别率,分别比梯度加灰度的方法提高了9.9%和42.7%。解决了粒子重叠的问题,并且对光场和成像效果有更好的鲁棒性。
