The invention can realize rapid conversion of three types of weirs, and study the correspondence between thin-walled weirs with different heights and cross-sectional shapes of weir crests, practical weirs and wide-crested weirs with different heights, shapes and weir crest widths under different flow velocities and water levels. The characteristics of the weir flow can be expanded, the research scope of the weir flow test can be expanded, the practicality and maintainability are high, and it is beneficial to the development of hydraulics teaching and scientific research.

The invention discloses a minimum spanning tree-based mosaic method for panoramic images taken by a mobile phone, which comprises the following steps: tracking and collecting images: the user acquires several images of the panoramic photos to be taken according to the camera tracking guide; image matching: using the matching between images Relation constructs the relational graph structure between images; establishes the minimum spanning tree: establishes the corresponding minimum spanning tree according to the relational graph structure in image matching; image stitching: takes the image corresponding to the root node of the minimum spanning tree as the canvas plane of the final puzzle, The path from the root node to each node is used to generate the perspective transformation from each image to the canvas plane. The invention has a reasonable design, simplifies the complex procedures in the process of taking pictures, can achieve good image stitching effects, and can effectively alleviate the final puzzle The distortion caused by the medium perspective transformation greatly improves the image stitching effect.

The invention relates to a compound modified asphalt preparation device and a preparation method. The preparation device of the invention is characterized in that a temperature controller is connected with a heater which is arranged in a safe explosion-proof incubator; a speed controller is connected with a high-temperature stirrer, and the lower part of the high-temperature stirrer is arranged in a heater; and one end of a condensation pipe is connected to the safe explosion-proof incubator via a glass pipe, and the other end is connected to a collection bottle. The invention solves the defects of using a common modified asphalt for preparation or using a reaction extruder for preparation in the prior art. The invention can ensure that nano particles and polymer fully disperse in asphaltevenly, so that the processed modified asphalt reaches the technical requirements of Standard Specification for Construction and Acceptance of Highway Asphalt Pavements which is published by the Ministry of Communications. The invention simplifies the complex procedures for preparing polymer-matrix nanocomposite modified asphalt and reduces environment pollution caused by toxic substance in the modified asphalt preparation process; and the softening point of the compound modified asphalt is slightly higher than that of the compound modified asphalt prepared with a high speed shearing method, and low-temperature ductility is greatly improved.

The invention discloses a bridge reinforcement assembly graph adjusting method applied to bridge design software, providing a visual graph operation interface for editing skeleton reinforcing steel bar information for bridge construction member design software, and allocating corresponding skeleton reinforcing steel bar to bridge construction member by icon operation. A designer only needs to click all the icons on the visual graph operation interface by mouse, so as to conveniently display the required skeleton reinforcing steel bar information. The designer drags the information icon for skeleton reinforcing steel bar by mouse, and a corresponding changing drawing of the adjusted skeleton reinforcing steel bar can be seen, the dragging is carried out until the skeleton reinforcing steelbar is adjusted to the expected effect position. The icon reflecting the skeleton reinforcing steel bar information and the adjusted skeleton reinforcing steel bar are linked and are corresponding inreal time. The invention effectively simplifies the original trivial procedure that skeleton reinforcing steel bar information is input manually, skeleton reinforcing steel bar is allocated to bridgeconstruction member by operating the icon for skeleton reinforcing steel bar, operation is simple, and time and effort can be saved.

A rotary printing machine includes a printing cylinder, at least one clamping unit mounted on a printing surface of the printing cylinder, and a feeding control mechanism and an unloading control mechanism mounted to a lateral side of the printing cylinder for changing the clamping state of the clamping unit. When the clamping unit is moved to an unloading position, the unloading control mechanism can be operated to control the clamping unit to maintain a closed state, so that a workpiece can be brought by the printing cylinder to a feeding position again. Then, the feeding control mechanism can be operated to control the clamping unit at the feeding position to maintain a clamped state, so that printing can be repeated on the workpiece to form multiple layers of ink and create three-dimensional printed layers showing a specific visual effect.
