Based on the land use data of Fujian Province in 1990, 2000, 2010, and 2020, we analyzed the spatiotemporal change characteristics of land use types, the spatial differentiation of cold and hot spots under the sea-land gradient using the buffer gradient zone method, and the reasons for spatial differentiation of land use change. The results showed that: 1) the area changes of main land use types had different trends with increased distance from the coastline in the past 30 years. Among them, the change of cultivated land and urban and rural construction land area showed a gradient trend of continuous decrease, and the changes in the area between them within 20 km from the coastline were the largest, which were -1,317.12 and 1,799.8 km2, respectively. The change of forestland and grassland area showed a trend of "decreasing, increasing and decreasing" and concentrated in the 140-240 km gradient zone; 2) from the perspective of conversion types, the proportion of the first 10 land use types changed mainly from cultivated land and grassland to forest and from cultivated, forest, and grassland to urban and rural construction land in the following order: coastal gradient zone (44.23%), transitional gradient zone (37.31%), and inland gradient zone (15.03%). Regarding spatial distribution, the decrease in cultivated land and the increase in urban and rural construction land were mainly distributed in the coastal gradient zone, while the grassland decrease and woodland increase were mainly distributed in the transition and inland gradient zones; 3) from the perspective of the comprehensive dynamic degree, the comprehensive dynamic degree within 20 km from the coastline was the highest (0.75%) in the past 30 years, and the degree of change was the most severe. Concerning a single dynamic degree, the dynamic degree of urban and rural construction land showed a gradient change that first increased and then decreased, and its rate of change was much higher than that of other types; 4) land use change has significant spatial heterogeneity under the land-sea gradient, and taking the year 2000 as the time boundary, the hot spots showed the spatial aggregation characteristics of "transferring from inland areas to coastal areas" and from "more in the north and less in the south" to "more in the south and less in the north". The characteristics of land-sea gradient differentiation of land use change are closely related to regional development strategies and ecological environment construction policies at different stages of Fujian Province from 1990 to 2020.

Aiming at the problem of blade erosion of a mining counter-rotating fan in actual operation, the SST k-w turbulence model and the Finnie erosion model were used to numerically simulate the gas-solid two-phase flow field of the fan at different blade installation angles. Firstly, fan performance tests were carried out with fan static pressure, fan power and fan efficiency as evaluation indexes, and the accuracy of the numerical calculation methods and models was verified. Then, the erosion characteristics of the blade pressure surface and the distribution patterns of the gas-solid two-phase flow field of the fan were analyzed according to the six designed blade installation angle cases. Finally, the performance parameters of the gas-solid two-phase flow fan with different blade installation angles were compared, and the blade installation angle with the best anti-erosion effect and the optimum fan performance was determined. The results show that the average erosion rate of the blade surface is reduced by 6.0 x 10-8 kg/(m² s) after increasing the rear stage blade installation angle compared to the original blade installation angle. Increasing the rear stage blade installation angle reduces the separation vortex at the leading and trailing edges of the rear stage blade, improves the fan performance, and achieves the purpose of blade anti-erosion.

In order to clarify the aerodynamic enhancement on the bipolar transverse plate electrostatic precipitator (BESP), based on the classical Deutsch formula of electrostatic precipitator (ESP), the aerodynamic influence on the collection efficiency of BESP was analyzed. The numerical simulation results show that the migration velocity of charged particles in the BESP is the sum of the electrostatic migration velocity and the aerodynamic migration velocity. The aerodynamic enhancement amplitude of windward side of the plates is stronger than that of the leeward side. Due to the lower speed in the return flow region, the leeward side of the plates are the main dust deposition areas. The experimental results show that the aerodynamic migration velocity is proportional to the quadratic of the gas velocity. When the wind speed is lower than 1. 5 m/s, the aerodynamic migration velocity is strengthened by the gas flow. However, when the wind speed is higher than 1. 5 m/s, the aerodynamic migration velocity is reduced by the dust re-entrainment. When the structural parameters are constant, the correction formula of the collection efficiency shows that the collection efficiency of BESP is determined by both electrostatic force and aerodynamic force.

In order to explore the influence of different ions in the marine environment on the microscopic particle structure of the solidified soil, the characteristics of the microscopic particle structure of the steel slag + cement solidified soil and cement solidified soil in the erosion environment were studied. Three kinds of ions with great influence in seawater were selected to carry out the erosion test on the solidified soil samples, and the samples with different erosion ages were scanned by electron microscope. The morphological characteristics of the bulk microscopic particle structure were combined with the unconfined compressive strength (UCS) of the sample to obtain the interrelated characteristics of the change of the microscopic particle structure and the change of the macroscopic strength of the solidified soil. The research results show these as follows. The macroscopic strength changes and microscopic particles of cementsolidified soil (CS), steel slag-cement-solidified soil (A-SSP-CS) and steel slag-cement-solidified soil ( SSP-CS) under the action of Mg 2 + The structural changes have a certain correlation, and the correlation is better in the early stage than in the later stage. The macroscopic strength changes and microscopic particle structure changes of CS and A-SSP-CS in the Cl - environment are well reflected in the whole test stage. In SO 2 - 4 environment, the macro-micro correlation of CS and A-SSP-CS is better, and the macro-micro correlation of SSP-CS in the early stage is better than that of SSP-CS. better than the latter.

To further clarify the effect of lethal conditions on the quality of grouper(Epinephelus lanceolatus) and to improve the quality of grouper during refrigeration, five different lethal methods were used to treat grouper, with the following groups: Ⅰ: lethal by ice burial; Ⅱ: lethal by knocking on the head; Ⅲ: lethal by subjecting live grouper to temperature gradients of 18, 14, 10 and 6 ℃ (each temperature treatment for 20 min); Ⅳ: lethal by subjecting live grouper to temperature gradients of 18, 12 and 6 ℃ (20 min at each temperature); Ⅴ: lethal by subjecting live grouper to temperature gradients of 18, 6 ℃ (20 min at each temperature). The grouper was then rapidly reduced to 0 ℃ in the centre of the fish body by micro-freezing machine and refrigerated at 0-4 ℃. The effects of changes in the sensory evaluation, textural characteristics, pH, lactic acid content, sulfhydryl content, volatile salt nitrogen (TVB-N), total bacterial colony count and other quality evaluation indicators of the fish during the freezing period were subsequently measured and analyzed. The results showed that the five groups of lethal treatments had significant effects on the quality of fish meat during refrigeration, in descending order: sensory evaluation and TVB-N: group Ⅴ> group Ⅰ> group Ⅱ> group Ⅳ> group Ⅲ, texture: group Ⅳ> group Ⅴ> group Ⅱ> group Ⅰ> group Ⅲ, lactic acid content and pH: group Ⅴ> group Ⅰ> group Ⅱ> group Ⅳ> group Ⅲ, sulfhydryl content and total bacterial colony: group Ⅰ> group Ⅱ> group Ⅴ> group Ⅳ> group Ⅲ. > group Ⅳ > group Ⅲ. This indicated that the lethal treatment by gradient cooling was significantly better than the lethal treatment by head knocking and ice burying, and the temperature difference interval in gradient cooling should not be too wide. The results of the quality evaluation of all the indicators showed that group Ⅲ had the best lethal treatment, as the narrower temperature range made the process of grouper death less stressful, and the lactic acid content, pH and total sulfhydryl group were relatively stable, which was more effective than the other four groups in delaying the reduction of textural characteristics and sulfhydryl group content and inhibiting microbial activity, thus prolonging the shelf life of the fish samples.

The experiment was to study the effect of different forage ratio on growth and development, carcass trait and meat quality of Angus cattle. A total of 64 healthy six-month-old Angus cattle (half bulls and half cows) with similar body weight were randomly divided into four groups with four replicates in each group and four cattle in each replicate. Each group cattle was fed a total mixed diet with different forage proportions. The pre-test lasted for 15 d and the formal test lasted for 360 d. The results showed that the body weight of bull and cow in group 1 was significantly higher than that in group 3 and control group at 12 and 18-month-old (P<0.05), the body weight of bull in group 2 was significantly higher than that in group 3 and control group at 12 and 18-month-old (P<0.05), and that in group 2 was significantly higher than that in group 3 and control group at 18-month-old. Average daily gain of bulls and cows in group 1 was significantly higher than that in control group and group 3 at 7~12-month-old (P<0.05), average daily gain of bulls and cows in group 1 was significantly higher than that in group 3 at 13~18-month-old (P<0.05), average daily gain of bulls and cows in group 1 was significantly higher than that in group 3 at 7~18-month-old (P<0.05). The pre-slaughter weight, carcass weight and slaughter rate of bulls in group 1 were significantly higher than those in control group and group 3 (P<0.05), and the eye muscle area and back fat thickness of bulls in group 1 were significantly higher than those in other groups (P<0.05). Muscle and fat color in group 1 and group 2 were significantly lower than those in control group (P<0.05). The study indicates that the forage and feed ratio of group 1 is better for improving the growth and meat quality of Angus cattle. [ABSTRACT FROM AUTHOR]

In order to conduct an in-depth study on the deterioration mechanism of marine solidified soil, Python + OpenCV image processing software was used to process and extract data from SEM images of marine solidified soil with different curing types and erosion time. On the basis of considering the influence of the difference in picture brightness, the fractal theory was introduced to quantitatively analyze the variation of microscopic particles of solidified soil. At the same time, combined with the test results of unconfined compressive strength, the relationship between the microscopic particle structure change of marine solidified soil and the macroscopic mechanical properties was established. The results show that: the difference of brightness of different SEM images will have an impact on the results of the study. In the binarization process, the error can be reduced by controlling the whole amount of pixel. The microscopic particle variation of solidified soil eroded by seawater has fractal characteristics. For cement solidified soil (CS) and steel slag powder + cement cured soil (A-SSP-CS) mixed with activating agent, the fractal dimension of microscopic particles decreases gradually with the extension of erosion time, while the fractal dimension of microscopic particles increases with the extension of erosion time for steel slag powder + cement solidified soil (SSP-CS). For CS and A-SSP-CS, the unconfined compressive strength (UCS) decreases gradually with the extension of seawater erosion time, and the fractal dimension of microscopic particles decreases gradually. For SSP-CS, its UCS will gradually increase with the extension of seawater erosion time, and the fractal dimension of particles will also increase gradually. [ABSTRACT FROM AUTHOR]
