It was revealed that the average infrared radiation temperature of damp rock increases with loading and keeps its change in step with the stress, and that the fluctuation of AIRI is much less, The AIRT increment of damp rock is higher than that of dry rock under unit load before destabilization and the fact shows that water will intensify the infrared radiation from loaded rock, but no obvious change was found on thermal image during the instantaneous fracture of damp rock.

A positive correlation was found between the solar activity and NO3- concentration in recent 1500 years. A long-standing issue of the nature of the solar activity during the Maunder Minimum was solved. An about 36a cycle was found in the solar activity. Low solar activity and weak geomagnetic field were responsible for the 36Cl peak at about 37ka BP. Climate change recorded in this ice core lagged insolation about 4ka during the last glacial maximum, about 1ka during the last deglaciation, and nearly 0ka during the Holocene.δ18O record also suggests that the variation in temperature on the Tibetan Plateau had some similar features to that in both Northern and Southern Hemispheres during the last deglaciation to some extent, which indicate that the tropics maybe play an important role on global climate change.

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.
