    Both PVA and shellac resin are easy to form film , and both of them are mainly used in mem-brane products. In order to improve the poor water vapor permeability and high brittleness of shellac resinafter film formation, PVA was specially added and blended with shellac resin in aqueous phase when w(PVA)was0%,10%,20%, 30% , 40% and 50% , respectively. The feasibility of the two films wasstudied and the film forming process was determined: preparing shellac resin aqueous emulsion and PVAaqueous solution respectively , and mixing them evenly at 50 ℃. Finally, pour the liquid into the petridish , dry and form a film. The surface morphology, water drop contact angle and hygroscopicity of thefilm - forming samples were measured respectively. The results show that PVA and shellac resin have cer.tain physical compatibility, and the addition of PVA improves the compactness of shellac resin mem-brane , and with the increase of PVA content, the compactness of PVA/ shellac resin membrane inereases , and the degree of chemical reaction between them is low. When the mass fraction of PVA was thehighest [a (PVA) 50% ], the hydrophilicity and hygroscopicity of PVA/ shellac resin membrane werethe strongest , which indicated that the addition of PVA improved the hydrophilicity of shellae resin, andthe greater the amount of PVA added, the greater the hydrophilicity and hygroscopicity of the membrane.

    Lac resin may possess glass transition temperature ( 7,). The T, and its theory will explainthe instability of lac resin and direct the storage temperature when it is confirmed. Under the polymerglass transition theory, we used X-ray Difraction(XRD), Dierential Scanning Calorimetry ( DSC )and Dynamic Themomechanical Analysis (DMA) to verify lac-resin's 7. According to the XRD graphand its degree of crystallinity of 2. 93% , we confirmed that lac resin is amorphous polymer. The averagespecific heat capacity difference of the five DSC measurements was 0.071 J/(g ·K). The DMA meas.urement showed the inflection point of storage modulus was 36.0 C, the peak value of loss modulus and loss factor were 27.3 ℃ and 36.0℃ respectively. Combining the XRD, DSC and DMA results, wecould confirm that lac resin possess the glass transiton and T,. The T, was 27. 3 ℃ under the DSC measurement and was 36.0 9C under the DMA measurement. The interpretation of the instability of lac resinwith the glass transiton and 7, was: when the storage temperature is below 7,, lac resin could be storedfor a long time even if the physical aging may affect the lac-resin's property; when the storage temperatureis above 7' , the storage time will be shortened because the reactive end-grups could motion which couldcause a chemical reaction. Therefore the storage temperature of lac resin should be below its 7.

     A skill-based society is a critical foundation for the construction of a strong nation and nationa.rejuvenation , requiring a large number of high-quality technical and skilled talents. Higher vocationacolleges should align with the demands of a skill-based society and continuously improve the quality andlevel of talent training. The key to achieving high-quality development in vocational education lies inteachers. As the central figure in implementing the fundamental task of moral education, ideological andpolitical teachers are not only guides for students in developing skills and contributing to the nation but al.so facilitators of cultivating high-quality technical and skilled talents. They are also pioneers in promotingthe idea that “ everyone learns skills, and everyone possesses skills.” To maximize the role of ideologicaland political teachers in the construetion of a skilled society within higher vocational education , in addi.tion to strengthening top-level design, improving mechanisms, and establishing institutional incentives, itis essential for ideological and political teachers to clarify their role orientation. They should transformtheir mindset, consciously undertake the responsibilities and mission entrusted by the development of askill-based society, and strive to be a “ great teacher” unified in both their roles as “Teacher of Expert.and “ Teacher of Morality."

    The study of landscape pattern evolution is an important way to understand regional ecological security and sustainable development. This study uses Landsat series remote sensing images from 2000 to 2020, combined with Fragstats 4.2 software to calculate landscape pattern indices. It also employs methods such as the transfer matrix and geographic detector to systematically reveal the spatiotemporal evolution characteristics and driving mechanisms of the landscape pattern in Chengjiang City. The results show that: 1) From 2000 to 2020, the land coverage types in Chengjiang City were dominated by cultivated land and forest land. Over the 20‑year period, the cultivated land area has decreased by 6.54 km², most of which was converted to grassland and forest. The forest area increased by 36.81 km², mainly from cultivated land, while the construction land area increased by 5.15 km², mainly from cultivated land and forest land. 2) Between 2000 and 2020, the degree of landscape fragmentation in Chengjiang City intensified, with both the Contagion Index and Shannon's Diversity index showing upward trends, indicating that human activities have led to increased landscape heterogeneity. This study validates the applicability of Fragstats in landscape analysis of plateau lake areas and provides data support for the land space optimization and ecological protection in Chengjiang City.

     In order to study the stress wave propagation law and failure characteristics of anchor solid un-der dynamic load, separate Hopkinson bars ( SHPB ) were used to conduct impact tests on anchor solidspecimens with different prestress and impact times , and the propagation law of stress waves and the char.acteristics of anchor failure were studied. The research results indicate that as the prestress increases , thepeak value of stress waves in the anchored surrounding rock gradually increases, and the attenuation rategradually decreases. Inereasing the prestress of the anchor rod significantly reduces the peak value of ten-sile waves at the free end of the anchor; As the prestress of the anchor specimen increases , the axial forceloss of the anchor increases faster, and the axial force loss rate shows a quadratic linear increase; whenthe prestress is small, there are more cracks in the surrounding rock at the anchoring free end. Undermultiple impacts, the crack distance is relatively close, and as the prestress increases, the degree ofdamage at the free end weakens; as the prestress increases, the maximum displacement during pullingdecreases. The original specimen that was not subjected to dynamic load does not show significant damageafter pulling. After dynamic load, as the preload increases , a certain degree of spliting failure occurs atthe anchor end , and the degree of splitting failure becomes weaker as the prestress continues to increase.

    Abstract (54)      PDF(pc) (1112KB)(76)       Save
    To address climate change and contribute to achieving the “Dual Carbon” goal, this study proposes integrating Enhanced Rock Weathering (ERW) technology with land leveling projects, by utilizing on‑site crushing of gravel to realize CO₂ sequestration and betterment of land. This technology utilizes silicate and carbonate minerals to fix CO₂ through weathering, thereby helping to replenish China's farmland resources. Simultaneously, it gradually releases essential nutrients such as potassium, phosphorus, magnesium, and calcium to improve soil conditions, increasing the soil pH by 0.2 to 2 units and boosting crop yields by 12% to 42%. Additionally, it synergistically strengthens the water and soil conservation capabilities of terraces. This model exhibits the potential to substantially reduce the carbon sequestration costs associated with ERW. The preliminary estimation indicates an annual carbon sequestration potential ranging from 398 million to 6.368 billion tons within China (conservative to optimistic estimates). The conservative estimation corresponds to approximately 48% of the current sink capacity of forest ecosystems, if the technology can be applied on a large scale and improve the carbon sequestration efficiency, the optimistic estimate suggests that it could cover more than 60% of the national annual carbon emissions. This technology can achieve “Treating Carbon with Waste”, providing an innovative solution for land leveling and carbon neutrality. In the future, more field experiments need to be conducted to optimize the implementation process and assess the long‑term ecological effects.

    Due to numerous impurities carried by sintering flue gas, ammonium sulfate crystallization becomes poor or even fails to occur, which hinders the stable production of the desulfurization system in the new area of Kunming Iron and Steel. To investigate the effect of pH on ammonium sulfate crystallization, NaOH, Ca(OH)₂, Na₂CO₃ and CaCO₃ were adopted to adjust the pH of the first‑effect ammonium sulfate solution, and the influences of pH on crystallization mass and yield‑increase ratio were studied. Sulfuric acid and ammonia water were used to regulate the pH of the second‑effect ammonium sulfate solution, and the effects of pH on crystallization yield, average particle size and coefficient of variation were explored. The results show that when the pH of the first‑effect ammonium sulfate solution is adjusted to approximately 5.25 with NaOH before evaporation, concentration and crystallization, a high ammonium sulfate yield of 63.493 g can be obtained with the minimum NaOH dosage of 0.283 g. The optimal pH for the second‑effect ammonium sulfate solution is 2.5. Under this condition, 61.162 g of ammonium sulfate crystals with large particle size, uniform particle distribution, regular morphology and low impurity content can be obtained, and the crystal morphology is highly consistent with pure ammonium sulfate. These findings can provide a reference for optimizing the crystallization process and increasing the output of ammonium sulfate.
