Abstract: The present disclosure provides a method for selecting key geological parameters of a to-be-prospected block.

Abstract: A loading apparatus for rock fracturing simulation includes an upper cover plate, a lower cover plate, lateral pressure pieces, and an acoustic measurement module top pillar. There are at least two lateral pressure pieces which are provided with a force applying face respectively for transmitting a radial force to a core sample. The upper cover plate, the lower cover plate and the lateral pressure pieces enclose a loading space for placing the core sample, and the lateral pressure pieces can slide along a radial direction of the core sample and relative to the upper cover plate or the lower cover plate. The lateral pressure pieces are provided with a sensor inserting hole for allowing a sensor to pass through respectively, and the sensor is attached to an outer peripheral wall of the core sample.

Abstract: Provided herein are a method and device of crew replanning for high-speed railway typical scenarios, and an electronic device and a computer-readable storage medium. The method includes: building a high-speed railway crew connection network; establishing a model for high-speed railway crew replanning; decomposing the model into a first sub-model for team leaders and a second sub-model for general crew members; and designing a Lagrangian relaxation algorithm to solve the first sub-model and the second sub-model.

Abstract: A positioning method and apparatus are provided. A specific embodiment of the method can include: acquiring description information of an object in an image to be positioned; searching in a database, based on the description information of the object in the image to be positioned, for preset images with description information matching the description information of the object in the image to be positioned, to obtain a set of preset images; matching the image to be positioned with the preset images in the set of preset images, to obtain an image matching the image to be positioned; and finally, determining a position of the image to be positioned based on preset position information corresponding to the image matching the image to be positioned.

Abstract: The present invention relates to an adsorbed gas content measuring instrument and its testing method. The instrument comprises sealed cylinders, gas collecting graduated canisters and a test box, wherein the sealed cylinders are provided with valves, the gas collecting graduated canisters are equipped with drain hole adjustment valves and vent hole switching valves fit for the valve ports, and there is a heating element and a temperature controller in the test box. The method is mainly as follows: put gas-contained samples and saturated brine into the sealed cylinder, seal the cylinder, feed water in the test box and heat the box, place the sealed cylinder into the water bath of the test box, introduce saturated brine into the gas collecting graduated canister, connect the canister and cylinder, open the drain hole of the gas collecting graduated canister, record the liquid level of the graduated canister and cut off the connection after the test.
