The invention discloses a design method for real gradation of asphalt mortar in a reduced asphalt mixture. The design method comprises the following steps: screening and cleaning coarse aggregate and measuring the density of the coarse aggregate; performing three-dimensional blue light scanning on the cleaned coarse aggregate according to different gears; data obtained through scanning are imported into three-dimensional software, and the medium axis, the short axis and the aggregate surface area of the minimum bounding box are obtained; fitting the obtained long, medium and short axes with the specific surface area to obtain a normal distribution function; weighing the mass of the aggregate of each gear and obtaining an average mass stability curve; gradation of the target asphalt mixture is obtained through a Marshall design method; the mix proportion of the asphalt mortar is obtained through calculation according to the model and the formula provided by the invention. According to the gradation design method, the distribution proportion of the fine aggregate, asphalt and mineral powder of the asphalt mortar in the asphalt mixture can be reduced, and the problem that the use amount of the asphalt and the mineral powder is not clear in the preparation of the asphalt mortar at present is solved.

The embodiment of the present invention discloses a method, device and system for processing curled images of intestinal spatiotemporal groups, and relates to the field of spatiotemporal group technology. The method comprises: acquiring a target image and sequencing data, and performing polygon annotation on the target curled area to obtain an image feature annotation file; analyzing the sequencing data to obtain expression matrix data; mapping the coordinate pixel matrix to the target image to obtain the original coordinate matrix; constructing a set of ordered bin areas, and mapping each cell in the RDS file to the bin area; performing spatial transformation on each bin area to form a straightened image and constructing a visual image based on the transformed coordinates. The present invention realizes the horizontal straightening and expansion of expression data, and can more clearly observe and compare the differences in gene expression of different intestinal segments. By using advanced image processing and data analysis techniques, different areas of the intestine can be divided and compared more finely, thereby revealing the regionalized characteristics inside the intestine.

The application discloses a control method based on a feedforward adaptive periodic complex expert controller, and comprises the following steps: identifying a power load of a generator and determining the generator with added or reduced load; according to the change trend of a low-low pressure steam header pressure and a steam pressure at a generator outlet, corresponding state types and control output periods are given; according to the output conditions met by the steam pressure, controller control output is carried out according to the met output conditions. The application not only relies on the low-low pressure steam pressure as feedback for control, but also considers the interference of the generator load and the inlet steam pressure on the low-low pressure steam pressure, so that fluctuations caused by untimely adjustment of single feedback control can be avoided, and fluctuations caused by the generator load and the inlet steam pressure can be overcome; through the technology, the controller can intelligently judge the danger of the low-low pressure steam pressure at the current time, and dynamically adjust the output period.
