A gigantic computerized air defense system, SAGE (Semi-Automatic Ground Environment) was designed to help the air Force track radar data in real time.

For operation on tracks, the track lift can briefly finish position monitoring, active operation, semi-active operation with high efficiency.

By analyzing apatite fission track data and inverse modeling, the thermal history of relevant rock assemblage has been studied qualitatively to semi-quantitatively in Ordos basin.
