Abstract: Disclose are a roadway/tunnel excavation robot and an automatic cutting control method. The robot includes a rack, a moving platform, a supporting and stabilizing mechanism, a milling mechanism, a telescoping mechanism, an inclined cutting feed adjusting mechanism, a horizontal swinging mechanism, a lifting mechanism and a controller. The milling mechanism includes a drive unit, a milling shaft, an eccentric rotary casing, a high-pressure jet nozzle unit, a tension and compression sensor and a direction sensor. Through the deflection of a center line of an inner hole of the eccentric rotary casing, the milling mechanism drives a milling cutter head to carry out a rotational oscillation motion for rock breaking; and the milling cutter head is in discontinuous contact with a rock mass. The telescoping mechanism, the inclined cutting feed adjusting mechanism, the lifting mechanism and the horizontal swinging mechanism are controlled such that the milling mechanism performs coal rocks milling.

Abstract: The present disclosure provides an ecological governance method based on erosion prevention and control for a gentle slope farmland and relates to the technical field of ecological governance of farmlands. The ecological governance method based on erosion prevention and control for a gentle slope farmland includes the following steps: sampling a gentle slope farmland to investigate erosion thereof; and determining erosion of a gentle slope cultivated land and selecting a corresponding recovery strategy based on a detection result of a sample, a soil quality index (SQI), and a comprehensive vegetation quality index (VQI), where the recovery strategy includes a natural recovery method and a biological-farming comprehensive recovery method; enclosing the gentle slope cultivated land, fallowing the gentle slope cultivated land and reducing tillage; exterminating insect pests and poisonous weeds in the enclosed area; and turning over straws under soil by a cultivator. The growth of poisonous weeds is inhibited.

Abstract: A data storage method, an apparatus, an electronic device, and a computer-readable storage medium. The method includes: detecting a mode switching behavior performed by an operator of a vehicle, the mode switching behavior being used to trigger switching a driving mode of the vehicle between a manual driving mode and an automatic driving mode; acquiring first data corresponding to the mode switching behavior, the first data including a vehicle identification of the vehicle, switching trigger information corresponding to the mode switching behavior and time information corresponding to the mode switching behavior; storing the first data to a blockchain network.

Abstract: Various techniques for controlling metal-containing contamination on a semiconductor substrate are provided herein. Such techniques may involve one or more of a post-development bake treatment, a chemical treatment, a plasma treatment, a light treatment, and a backside and bevel edge clean. The techniques may be combined as desired for a particular application. In many cases, the techniques are used to address metal-containing contamination that is generated during a photoresist development operation.
