Based on the geological structure conditions of known hot springs and ground thermometric data,the comprehensive remote sensing prediction of geothermal abnormal area was carried out. Seven favorable geothermal abnormal areas were put forward and the direction for hot spring exploration was given.
It is determined that distributin of geothermal anomalous region on late-Mesozoic era in ordos basin is Wuqi-Qingyang-Fuxian at the sourth of basin. It is decided that tectonic heat event occurred on 100~140 Ma of early-Cretaceous period in late-Mesozoic, continuous time of tectonic heat event is about 10~40 Ma.
It is a very active structural system at present, which reforms the antecedent structural plane, affects and controls the development of mophostructure and water system and controls the distribution of seismic actiyities and geothermal anomalous area.
This paper will narrate briefly the principle and its method of concretwork, which look for survey temperature of the infrared radiation in the surface soil of the underground thermal source and ullastrate with examples siluation of the actual use in underground thermal anomaly area.
The results obtained manifest a shift of the large-scale structures of the high-latitude ionosphere (the auroral oval, main ionospheric trough, hot zone, etc.) down to latitudes close to the latitude of the Kharkov radar.
In the later stage, after neck formation, particles are assumed to be emitted from a rapidly expanding hot zone of appreciably large initial dimension, which is strongly anisotropic in momentum space.
This consists in introducing a second reduced copper gauze roll, about 25 mm in length, just within the end portion of the hot zone of the permanent filling.
The properties evaluated clearly showed the suitability of these coatings for protection of different hot zone components in different types of engines.
