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。

Between 3.0 K and the triple point of neon (24.5561 K) T90 is defined by means of a helium gas thermometer calibrated at three experimentally realizable temperatures having assigned numerical values and using specified interpolation procedures.

ITS-90划分了几个主要温区和附属温区，并对每个温区的温度T90 给出了详细的规定。这些温区之间有重叠交叉部分，当重叠区域出现T90定义不唯一的情况时，两种定义同等适用。
