A series of theoretical and experimental studies on the microstrip patch antennas with dielectric superstrates is carried out systematically. Firstly, a comprehensive survey of the microstrip antenna technology and its theories are presented. Then, two analysis techniques, named as the spectral domain Green's function method and the spectral domain integral equation method are developed. The SDGF method is a simplified analysis technique, which takes advantage of the spectral domain immittance approach to find the dyadic Green's function for the stratified media, and obtains the complete closed-form formulas for radiation patterns, directivity, efficiency, gain etc. Some interesting calculated results are presented. The SDIE method is capable of determining resonant frequency, radiation characteristics, input impedance etc, for the covered microstrip patch antennas. Comparing with other full-wave analyses it reduced computation and mathematical labour remarkably. The singularities near the pole location of the surface-wave modes and the difficulty of the integral computation over infinite range of oscillating integrands are dealt with actively and documented well. Results predicted by the SDIE method agree extremely well with our experimental results for resonant frequencies of various superstrates. The superstrate effects on impedance and radiation characteristics also have been investigated experimentally so that the gap due to lack of measured data and computed results for multi-layered superstrate has been filled to some degrees and two useful observations have been achieved for weakening the resonant frequency shift and optimizing the microstrip antenna gain. As a meaningful application, the design and analysis of a 4×4 patch array are introduced.

For the condensed dynamic stiffness matrix in finite models which have finite number of freedom and any dynamic stifmess matrix of infinite system, the element of them is a transcendental function of eigenfrequency. And therefore transcendental eigenvalue problem is needed to be solved in order to get the natural frequency and modes of vibration.

The results show that the ratio of the released elastic energy to the damage dissipative energy can be served as a sensitive precursor of catastrophe. Furthermore the value of the non-dimensional ratio has a similar tendency to be 1 with different responses in the two failure modes, that is, the response function R always decreases in the gradual mode, while increases and tends to be infinite at the catastrophic point of the failure.

研究发现在灾变性破坏和非灾变性的渐进式破坏两种失效模式中，虽然系统中卸载所贡献的弹性能增量与损伤消耗和释放的能量增量的比值都有趋向于1的趋势，但是两者的趋近方式不同：灾变性破坏时表征能量比随控制变量变化特征的响应函数R有一个上升段，在灾变破坏点$R$趋向于无穷大，而非灾变性破坏中$R$始终是减小的。

Since there\'s inlayer heterogeneity in layered sandstone reservoirs and remaining oil potentials are mainly in thin or poor layers, which are mostly in delta front facies growth, this paper studies physical characteristics parameters interpretation methods for delta front deposit reservoirs to deepen the acknowledge to the depositional modes and features for further implementing the develop adjustment potentials and optimizing the potential tapping adjustment patterns. This practice has an important guiding sense to enhance the ultimate production recovery for mature oilfields.

我国大多数主力油田都属于陆相河流—三角洲沉积储层，如大庆的喇嘛甸、萨尔图和杏树岗等油田，这些油田基本上均已进入高含水后期开采阶段，尤其是以河流相发育为主的主力油层综合含水已达到90%以上，由于多油层砂岩油田存在层间的非均质性，油田的剩余油潜力主要集中在以三角洲前缘相发育为主的薄、差油层中，因此研究三角洲前缘相沉积储层的物性参数解释方法，深化其沉积模式及沉积特征的认识，进而落实油田开发调整潜力，优化调整挖潜方式，对提高老油田最终采收率具有重要的指导意义。
