Abstract: The present disclosure provides a system for measuring dynamic physical properties of a rack is configured to simulate various states of a rock, which facilitates the research of the dynamically changing physical properties of the rock. the system including: a kettle (202); a sample clamping device (10) including a lower end rod (103) and a fixed upper end rod (102), and a sample cavity is disposed between the upper end rod (103) and the lower end rod (102) and is located in the kettle (202); an overburden pressure device (400) configured to drive the lower end rod (103) to move up and down; a sample sheath (109) configured to sleeve a sample (101) located in the sample cavity, the sample sheath (109) being contractible inwards under pressure; a confining pressure maintaining device (402) configured to control a pressure in the kettle; and a heater (201) configured to control a temperature in the kettle.

Abstract: A sight spot guiding system and an implementing method thereof are provided. The method includes: a mobile terminal equipped with an RFID chip, after arriving at the sight spot, receiving a radio broadcast signal transmitted by an RFID reader set at the sight spot, and transmitting a radio response signal which carriers the ID of the present RFID chip; the RFID reader reading the radio response signal and then reporting the IDs of the RFID chip and the reader to an administration center, which, after receiving the IDs of the RFID and the reader, sends sight spot description information corresponding to the ID of the reader to the mobile terminal corresponding to the ID of the RFID chip, according to corresponding relationships between IDs of RFID readers and sight spot description information and between IDs of RFID chips and mobile terminals.
