电性源瞬变电磁地空逆合成孔径成像
全域视电阻率 克希霍夫偏移成像
2015/3/4
电性源地空瞬变电磁法具有工作效率高、勘探深度大、采集信号信噪比高、适用于地形地质条件复杂地区等优点.但是,到目前为止,由于尚未建立起该方法的解释系统,大大制约了该方法的发展.本文旨在建立起完整的地空电磁探测系统,丰富整个探测系统的理论.本文围绕地空瞬变电磁法全域视电阻率定义、瞬变电磁虚拟波场的克希霍夫偏移成像、逆合成孔径成像方法三个科学问题进行了系统研究.提出了用磁场强度定义全域视电阻率的迭代算法...
THE EQUIVALENCE THEOREM AND GLOBAL ANOMALIES
Bosons goldstein bosons current the standard model
2014/12/23
In the presence of some forms of global anomalies, the equivalence theorem, which relates the interactions of longitudinal gauge bosons to those of the Goldstone bosons, is not always valid. This can ...
Weak and electromagnetic interactions of hyperons: A chiral approach
Hyperon electromagnetic
2014/12/22
A range of issues in the field of weak and electromagnetic interactions of hyperons is presented from the perspective of (broken) chiral symmetry, together with an assessment of where important challe...
