the compressor has been developing towards the direction of high pressure ratio, high efficiency and wide stability margin. The flow in the air compressor blade channel presents a strong inverse pressure gradient. In order to reduce losses and improve the stability of the pressure aircraft, this paper adopts a slot structure from the leading edge of the blade to the suction surface. Air is injected from the front edge of the blade and discharged from the suction surface. The automatic optimization method is used to design the slot. The results show that the blade profile with inlet Mach number 0.4 and the diffusion factor 0.6, the total pressure loss of slotted blade profile is lower than that of unslotted blade profile, and the airflow Angle is greater than that of unslotted blade profile in the whole range of low loss incident Angle. In the incidence of 0 degree, due to the control effect of slotted jet on the boundary layer of the blade suction surface, the boundary layer separation zones on the blade suction surface becomes smaller and the wake also decreases, so the total pressure loss of the slotted blade profile decreases by 37%. When the incidence angle is 4°, the separation area of the suction surface boundary layer is larger, and the slotted jet has a better control effect on the boundary layer of the blade suction surface. However, When the incidence angle is -6°, boundary layer separation zones on the suction surface becomes smaller, and the boundary layer separation zones appears on the pressure surface, so the slotting effect is poor.

The application of quaternion rotation in ellipsoids and spheres is an intriguing field with significant implications in computer graphics, robotics, and physics simulations. The necessity to decipher quaternion rotation in ellipsoid is crucial. This research aims to utilize the principles of quaternion rotation in spheres to compute the equivalent in the ellipsoid. This involves the application of a linear transformation to convert quaternion rotation in ellipsoids into spheres. By controlling the full rotation of quaternions, the spheres can be transformed back into ellipsoids, achieving the ultimate goal of controlling quaternion rotation within an ellipsoid. The results demonstrate that this approach effectively addresses the quaternion rotation on the ellipsoid and aligns with the fundamental properties of quaternions. Furthermore, it serves as a significant aid in implementing quaternion rotation on the ellipse.

There are 19 faults in the main steam pipeline of a power plant, including structural failure, abnormal load bearing, abnormal displacement and other faults. Due to the low horizontal stiffness of the main steam pipe superheater header outlet, the pipe is subjected to periodic pulsation shock and resonates with the fixed frequency of the pipe. The failure of the main steam pipeline support hanger and pipeline vibration seriously affect the safe and stable operation of the unit. Through the calculation of piping stress and pipeline vibration test, a reasonable treatment scheme is formulated to solve the abnormal state of pipeline support and hanger and the pipeline vibration fault. It can provide reference for the maintenance of pipe system support and hanger and pipe vibration control of the same type of unit.

The compactness of aggregates has a significant impact on the workability of self-compacting concrete. The bulk density of aggregates is an effective parameter for evaluating the compactness of aggregates, reflecting the degree of compactness of the aggregate system. This study aims to explore the theoretical calculation model and application of the bulk density of green ferronickel slag as aggregates in self-compacting concrete. The influence of different particle size distributions and ferronickel slag content on the bulk density of the aggregate system was analyzed. Based on the calculation method of the maximum bulk density of aggregates, the bulk density of the aggregate system was calculated for different particle size distributions and nickel-iron slag content, and the effect of nickel-iron slag content on the compactness of the aggregate system was analyzed.

The rheological properties of emulsions are complex, leading to serious flow assurance issues that affect the economical and safe operation of pipelines. It has been reported that applying magnetic treatment technology can effectively improve the flowability of waxy crude oil. The study aims to investigate the influence of magnetic treatment on the viscosity of waxy crude oil emulsions. A dynamic electromagnetic treatment device was designed. The dynamic magnetic treatment experiments of waxy crude oil emulsion were carried out to explore the effects of magnetic field intensity and magnetic field frequency on the viscosity change of waxy crude oil emulsion. Research results show that with four different magnetic field frequencies, the viscosity of the emulsion decreases initially and then increases with the increase in magnetic field intensity. The variation law of emulsion viscosity with magnetic field intensity is related to the magnetic field frequency. When the magnetic field frequency is 100 Hz, the highest and lowest viscosity variation rates are 7.91% and -7.36%, respectively, which occur at the magnetic field strength of 110 mT and 30 mT, respectively. It is believed that applying a higher field strength electromagnetic field to the emulsion is beneficial for viscosity reduction. The research findings can provide guidance for the further study of the viscosity reduction of waxy crude oil emulsion magnetic treatment technology.

Ground target plays an indispensable role in UAV near-earth remote sensing geometric positioning, geographic registration, correction and improvement of remote sensing image accuracy and accuracy. Traditional ground targets are markers with distinct features, shapes and textures, and their dimensions are usually fixed. The UAV can provide high-resolution multi-spectral data with multi-spectral camera, so the target resolution will change as the UAV height increases and the camera band increases, in some bands of the multi-spectral camera, there will be non-response, which will affect the accuracy of target recognition and positioning. Based on the color, material, size and shape of target, a set of targets suitable for target recognition and location of multi-spectral camera is designed in this paper. In order to judge whether the target performance meets the requirements, this paper verifies the positioning accuracy of the target and its response in each channel of the camera. It is proved that the target plane error is about 10mm at 20 ~ 100m altitude, and the height error is about 40mm, and it can respond in ten channels, it provides experience and ideas for the design and development of multi-spectral camera targets.
地面目标在无人机近地遥感几何定位、地理登记、校正以及提高遥感图像精度和准确度方面发挥着不可或缺的作用。传统的地面目标是具有明显特征、形状和纹理的标记，其尺寸通常是固定的。无人机可通过多光谱相机提供高分辨率的多光谱数据，因此目标分辨率会随着无人机高度的增加和相机波段的增加而发生变化，在多光谱相机的某些波段会出现无响应现象，从而影响目标识别和定位的精度。本文根据目标的颜色、材质、大小和形状，设计了一套适合多光谱相机目标识别和定位的目标。为了判断目标的性能是否满足要求，本文验证了目标的定位精度及其在摄像机各通道中的响应。结果表明，在 20 ~ 100m 高度范围内，目标平面误差约为 10mm，高度误差约为 40mm，并能在十个通道中响应，为多光谱相机目标的设计和开发提供了经验和思路。

Based on the background of the 2 # coal seam mainly mined by Caojiatan Coal Mine in Yulin Mining Area in northern Shaanxi, this paper adopts the Scanning electron microscope test method to obtain the fracture size and structural characteristics of coal samples through the process of sample preparation drying testing analysis. After testing, the cracks in the main coal seam samples of Yulin mining area in northern Shaanxi show irregular distribution, with small branch cracks mainly derived from larger main cracks. The closed form crack structure is a wedge-shaped structure, while the open form crack width is in an disordered state. Some cracks have no fixed width or size, and the main crack width range is 90μm~617μm, the width range of branch fine cracks is 0-21 μm; It can provide basic support for the application of water injection dust reduction engineering in the later stage.
