Abstract: This application provides a bullet-screen comment display method, where the bullet-screen comment display method includes: determining bullet-screen comment area basic information corresponding to a target bullet-screen comment from a target picture; identifying an invalid pixel set of the target picture; determining a bullet-screen comment filling area corresponding to the target bullet-screen comment based on the bullet-screen comment area basic information and the invalid pixel set; and filling the bullet-screen comment filling area with the target bullet-screen comment.

Abstract: The present invention provides a device for blocking plasma backflow in a process chamber to protect an air inlet structure, comprising an air inlet nozzle tightly connected to an air inlet flange. The inner cavity of the air inlet nozzle is provided with an air inlet guide body, wherein the air inlet guide body has an upper structure, a middle structure, and a lower structure, the upper, middle, and lower structures are an integrated structure, the upper, middle, and lower structures are all cylindrical, the cross-sectional diameter of the upper structure is smaller than that of the middle structure, a gas gathering area is arranged between the middle structure and the lower structure, and the middle structure and the lower structure are connected by the gas gathering area.

Abstract: In a folding mechanism, a first housing seat is rotatably disposed on a first screen support plate, a second housing seat is rotatably disposed on a second screen support plate, and a third screen support plate is movably connected to a base in a support direction of the third screen support plate; the first housing seat is rotatably connected to the base via a first swing arm, the second housing seat is rotatably connected to the base via a second swing arm, the first screen support plate is slidably and rotatably connected to the base via a third swing arm, the second screen support plate is slidably and rotatably connected to the base via a fourth swing arm, a rotation axis of the first swing arm is spaced apart from that of the third swing arm.

Abstract: A motion control method, a robot controller, and a computer readable storage medium are provided. The method includes: calculating an inverse Jacobian matrix of a whole-body generalized coordinate vector at a current time relative to an actual task space vector of a humanoid robot; calculating a target generalized coordinate vector corresponding to a to-be-executed task space vector at a current moment by combining an actual task space vector and the to-be-executed task space vector into a null space of the inverse Jacobian matrix according to preset position constraint(s) corresponding to the whole-body generalized coordinate vector; and controlling a motion state of the humanoid robot according to the target generalized coordinate vector. In this manner, the motion of the humanoid robot is optimized as a whole to achieve the purpose of controlling the humanoid robot to avoid the limits of the motion of joints.

Abstract: The present invention discloses a method and system for protecting the operation of a train under an air pollution environment.

Abstract: A use of an application mode of Trichoderma harzianum (T. harzianum) in growth and induced resistance of Nicotiana tabacum (N. tabacum) includes the following specific operation steps: S1. experimental materials: preparation of test media and bacterial solutions; S2. experimental treatments: S2.1 control treatment; S2.2 seed soaking treatment; S2.3 root irrigation treatment; and S2.4 foliar inoculation treatment; S3. test determination indexes and methods: S3.1 determination of biological traits; S3.2 determination of physiological and biochemical indexes; and S3.3 determination of disease resistance and induced resistance indexes; and S4. data processing: subjecting data to a difference significance test. Different application modes of T. harzianum all can promote the growth of N. tabacum plants and reduce the occurrence of tobacco black shank (TBS), among which a root irrigation treatment at a transplanting stage leads to an optimal effect.

Abstract: A first device is logged in with a first user account. The first device displays an avatar of a second user account in a first user interface of the first device. In response to an interaction instruction triggered on the avatar of the second user account, the first device generates an interaction message according to a first field corresponding to the first user account, an action description field corresponding to the interaction instruction, and a second field corresponding to the second user account. The first device transmits the interaction message to a second device that is logged in with the second user account.

Abstract: An image processing method includes detecting human skeleton key points of a character in an image, and for the to-be-processed image, generating a cropping region based on the human skeleton key points and a preset rule, and using the to-be-processed image selected by using the cropping region as an output object. The human skeleton key points and the preset rule are set based on photographing experience.

Abstract: A service processing method, a device, a terminal and a server are provided. In some embodiments, the method includes: obtaining an operator identifier, when a coupon verification operation is detected on a service page of a public service account; invoking a code reading interface of an internet application to which the public service account belongs, to obtain a code of a coupon to be verified; generating a coupon verification service request based on the operator identifier and the code of the coupon; sending the coupon verification service request to a server, to cause the server to process a coupon verification service based on the operator identifier and the code of the coupon and return a process result to the terminal; and outputting the process result on the service page of the public service account.
