Methods In the study,experimental animals were divided into three groups. Thiamazole was used to replicate the model of maternal pregnant hypothyroidism. The infant rats were innate hypothyroidism. T4 substitution group rats were administrated with T4 from postnatal 0 day as well as the same days normal neonatal rats as control. TdT-mediated dUTP nick end labeling was carried out to detect the positive cells of PCD in cortex and hippocampus of postnatal 7,14 and 21 days rats. Immunohistochemical staining technique was employed to detect Bcl-2 and Bax proteins in relevant sections. Experimental data were statistically analysed by One-Way ANOVA, SNK-q test and Spearman rank correlation analysis.

To overcome the drawbacks in the weight and cost of the antenna with the corrugated soft surface, a new patch antenna with patch rings is designed. Its weight is about 1/4 less than the antenna with the corrugated soft surface and it is inexpensive. Good experimental results are obtained. The radiation pattern of the antenna is more rotationally symmetric, and a more reduction on the sidelobe levels of the antenna is achieved as compared to the antenna with the corrugated soft surface. In conclusion, in the present thesis both theoretical and experimental research works have been carried out intensively on patch antennas based on photonic-bandgap structures.

为了克服皱褶软表面天线份量重，加工费用贵等缺点，我们对空气介质的皱褶圆环结构软表面天线进行了改进，将周期分布的皱褶圆环平面化，并保持结构的软表面特性，设计出了一种新的平面圆环结构的软表面天线并进行了实验研究，加工的平面圆环结构天线比皱褶圆环结构天线重量减轻了约1/4，加工费用大大降低，所取得的实验结果显示，该平面圆环结构软表面天线的方向图的轴对称性得到了改善，在俯仰角从0°～-90°的范围内天线H面的波束与E面重合，与皱褶圆环结构相比，天线的旁瓣和背瓣受到了更大的抑制，E面方向图上+120°方向的旁瓣被明显削弱。

The flow parameters, which controlled the heat transfer phenomena in the coolant channel of the piston, are identified; the experimental facilities and program will be established in accordance with the parametric conditions experienced by a real marine diesel engine. The experimental result for the flow within smooth-walled duct under the reciprocating motion will be used as the reference datum to assess the results for the study of heat transfer augmentation. As an attempt to enhance the cooling performance, the ribs will be installed in the coolant channels which flow was orthogonal mode for the piston moving direction. Finally, the results obtained for the tests with heat transfer augmentation devices will be compared with the smooth-walled test results.
