The ANNs models of the periodic defected ground structures and a novel combinatorial nonperiodic defected ground structures with the characteristic of double stop band have been developed in this paper. The structure sizes of DGS and the frequencies are defined as the input samples of ANNs, the parameters of transmission coefficient calculated by FDTD method are sampled and defined as the output samples. For the PDGS with biggish structure sizes the transmission coefficients have the tiny dither owing to abnormal disturbance and the training samples have been smoothed by the least square method and five-spot triple smoothing method.

本文采用神经网络对周期性缺陷接地结构和一种新型的具有双阻带特性的组合式非周期性缺陷接地结构进行分析建模，将其结构尺寸和频率作为输入样本，对FDTD法计算出的传输系数参数进行抽样并将抽样结果作为输出样本，然后采用贝叶斯正则化算法对神经网络进行训练。

The results show that : basic manufactured tank, welders were no longer needed in Tooling process, the cutting process is not strictly adhered to. Defects generated through the floor to form oil leakage is the main reason production base metal microstructure revealed the existence of a more serious segregation, makes steel welding performance is changing for the worse. Failure welding defects as easily lead to hidden dangers.

结果表明：油罐基本制造完成后，焊工在切除不再需要工装过程中，不严格遵守切割工艺，所产生的底板贯穿性缺陷是形成油罐泄漏的主要原因，金相显示制作母材中存在着较严重的偏析，使得钢材的焊接性能变得较差，容易引起焊接缺陷成为失效隐患。

本文利用出土简牍，对汉代烽火制度、缺陷以及匈奴人对其缺陷的利用等问题进行了分析。

And then the designing process and method of the system are expatiated, including the analysis of the system performance, functional module partition, equipment selection and installation, dynamic real-time image acquisition, defect detection arithmetic, and so on. It is worth mentioning that, we have creatively achieve to capture the dynamic images of blood lancets automatically, and we have designed a simple but effective arithmetic for detecting defects according to the image features of blood lancets. Finally, we analyse the experimental results and evaluate the system performent.

在系统设计的过程中，创造性地实现了动态图像的自动采集，对采血针图像的特征进行了有效的分析，采用图像裁剪、直方图均衡化的图像增强方法、邻域平均法的平滑处理方法、基于迭代法自动确定阈值的图像分割方法等对采血针图像进行预处理，根据采血针缺陷的形状特征设计了简单易行精度较高的缺陷检测算法。
