The invention discloses a teaching aid for demonstrating the arc length between two equally latitudinal points of a spherical surface. The teaching aid comprises a supporting structure, a connecting mechanism and a measuring mechanism. The measuring mechanism comprises supporting warps, supporting wefts and an upper supporting seat, wherein the supporting warps and the supporting wefts are uniformly distributed. The supporting wefts are fixedly arranged on the upper hemisphere of the supporting warps. A second supporting rod is fixedly arranged on the connecting mechanism. The other end of the second supporting rod is connected with a third supporting rod. The end part of the third supporting rod is connected with a fourth supporting rod through a connecting rod. The connecting rod is hinged to the third supporting rod. The other end of the fourth supporting rod is fixedly provided with a fan-shaped measuring ruler. According to the invention, the arc length between two equally latitudinal points of the spherical surface can be quickly measured, and the calculation time is saved. Meanwhile, an infant or a pupil can more intuitively feel the difference between the arc length and the straight length between the two points of the spherical surface, so that the demonstration efficiency of the arc length on the spherical surface is greatly improved. The understanding of students on the flight route of an aircraft is enhanced.

The present invention discloses a teaching aid for demonstration for an arc length between two points with different spherical latitudes and longitudes. The teaching tool comprises a support structure, a connection mechanism and a measurement mechanism. The measurement mechanism comprises uniformly distributed support longitude lines, support parallel lines and an upper supporting seat, a second support bar is fixedly installed on the connection mechanism, the other end of the second support bar is located at the centre of the sphere of a semi-spherical holding cavity, the end portion of the second support bar is connected with a third support bar through a spherical pair, a sector measuring ruler is fixedly installed at the other end of the third support bar, and the arc-shaped end face of the sector measuring ruler is pasted to the spherical surface of the semi-spherical holding cavity. The teaching aid for demonstration for the arc length between two points with different spherical latitudes and longitudes can rapidly measure the arc length between two points located at the spherical surface to save the calculation time, allow children or pupils to more visually feel the arc length between the two points located at the spherical surface and the straight length between the two points located at the spherical surface, greatly improve the demonstration efficiency of the spherical surface arc length and enhance the students' understanding to the course lines.

The invention discloses a method, mobile equipment, desktop computer equipment and a system for document presentation based on cloud. The method for the document presentation comprises the steps that: Step 101, the mobile equipment sends an authentication request to the desktop computer equipment and a cloud server; the cloud server verifies the authentication request according to preset authorization information; if the verification passes, the cloud server sends verification passing identification to the desktop computer equipment; and the desktop computer equipment records and sends the verification passing identification to the mobile equipment; Step 102, the mobile equipment browses and selects a document stored in the cloud server, sends a link of the selected to-be-presented document and the verification passing identification to the desktop computer equipment to allow the desktop computer equipment to verify presentation authority of the mobile equipment again, and downloads the to-be-presented document from the cloud server according to the link; and Step 103, the mobile equipment sends control instructions and the verification passing identification to control the desktop computer equipment to present the to-be-presented document. With the adoption of the technical scheme, the security of the document presentation is ensured.

The invention discloses a hydraulic training platform, which includes a base, side columns are fixedly connected to both sides of the top of the base, a top plate is fixedly connected between the two side columns, and vertical hydraulic components are arranged on the top plate. A pressure plate is installed at the bottom of the assembly, and a plurality of pressure rods are evenly distributed along the circumferential direction on the bottom surface of the pressure plate; a motor is arranged inside the base; in the present invention, by placing different samples in different material trays, more people can watch them at the same time , improve the efficiency of the demonstration, and through the cooperation of the cross and the cross groove, the material tray can be moved down quickly for a certain distance, and the trainees can finish watching before the pressure plate rises to the initial position, which further improves the efficiency of the demonstration, and through The motor drives the rotating disk to rotate half a circle, so that the front and rear samples can be exchanged, so that students can watch at a closer distance, ensuring the viewing effect. Efficiency for your next presentation.

Embodiments of this application disclose a target object rendition method performed by an electronic device having a camera and a display screen. The electronic device photographs an entity card by using a camera. From the photograph, the electronic device obtains a to-be-recognized target object that is printed on the entity card and then image interpretation data of the to-be-recognized target object, the image interpretation data being used to reflect a feature of the to-be-recognized target object. After matching the image interpretation data with prestored image interpretation data, the electric device obtains a prestored target object corresponding to prestored image interpretation data matching the image interpretation data. Finally, the electronic device invokes an application (e.g., a computer game) associated with the prestored target object (e.g., a virtual character of the computer game) and renders, using the application, the prestored target object on the display screen.

A device displays a first page of a set of related content on the display. While displaying the first page on the display, the device detects an operation action performed by a user for switching from the first page to a second page of the set of related content. In response to detecting the operation action performed by the user: the device slides the first page of the set of related content in a first direction off the display, the device slides additional information that is distinct from the second page of the set of related content onto the display in the first direction, while the first page is sliding off the display, and the device displays the second page of the set of related content after at least a portion of the additional information is displayed on the display for at least a preset threshold amount of time.

The present invention belongs to the technical field of probability demonstration, specifically a mathematical probability demonstration device, comprising a box, the bottom wall of the box is provided with a rectangular groove, and a spring plate is hinged at the rectangular groove, and one end of the spring plate is hinged on The rectangular groove is close to one end of the middle part of the bottom wall of the box body, the other end of the spring plate is close to the inner cavity edge of the box body and rotates freely, the top of the spring plate is provided with a guide groove, and the depth of the guide groove at the end far away from the hinge point of the spring plate is greater than The depth of one end close to the hinge point of the spring plate, the width value of the end of the guide groove away from the hinge point of the spring plate is smaller than the width value of the end close to the hinge point of the spring plate; the present invention marks different colors on both sides of the disc, and through the color The recognizer recognizes the color on the disc, so that the results of disc throwing can be counted accurately and quickly, replacing the manual counting method, making the counting process fast and efficient, and reducing possible errors and errors in the counting process, thus ensuring the accuracy of the probability.
