The invention provides a novel method for monitoring strain on an earth crust shallow layer. Practice proves that the strain on the earth crust shallow layer is related to an earthquake precursor, so that the method is a novel method for monitoring the earthquake precursor. By the method provided by the invention, the characteristics of particle media are used, a stress sensor is not arranged in a drill hole of a bed rock on an earth crust deep layer but is embedded in sand of the earth crust shallow layer, and water around the stress sensor is displaced into clean water for washing sand in spite of an earth surface soil stratum or an earth surface bed stratum. The stress sensor is buried below a frozen soil layer and above an underground water level.

The invention relates to a high pressure spring force burst control system, and belongs to the technical field of racing cars. The high pressure spring force burst control system comprises a car body, motors, telescopic rods, a lifting rod, a strong spring and stress sensors. The two ends of the first telescopic rod are connected with the first motor and a steering wheel respectively, the two ends of the second telescopic rod are connected with the second motor and a front support respectively, the two ends of the third telescopic rod are connected with the second motor and a rear support respectively, the two ends of the lifting rod are connected with the third motor and a top cover respectively, and the strong spring is arranged under a car seat. When an electronic control unit monitors collision of a racing car through the stress sensors, a driver is ejected out of the car through the strong spring to reduce the damage level of the racing driver. The high pressure spring force burst control system is reasonable in structure, simple in design, and suitable for optimization design of a racing car collision accident damage reducing system.
