In the Context of Frequent Trade Remedy Measures :Optimization Strategy for China-Indian Trade in goods SHl Guanqing , LONG Wenyi, HE Zhichang HPMug2oMmNrOfxWQHLiEksa6s0hFu9Ox348d7QefarYlaFR5ArkhOwm3Da1pmxmxCtenj1+6luWD#r#n+EPn9L6Ce+9onqnMlT+i    2025, 41 (4): 137-.   DOI: 10.3969/j.issn.1009-0479.2025.04.020 Abstract （84）      PDF（pc） （953KB）（16）       Knowledge map    Save  India frequently initiates trade remedy measures such as anti-dumping, subsidies, safeguardmeasures, and special safeguard measures against Chinese exports, which have affected the realization ofbroad frade prospects between China and India. Although bilateral trade in goods between China and In-dia has been growing rapidly, the trade status is unequal, and there is a structural convergence of exportproducts. Based on the data from 2000 to 2023, India's trade remedy measures against China show alarge total volume, various types, and a relatively concentrated scope. The core reasons lie in the lack ofmutual trust in development between the two countries , India's huge trade deficit, its competitive disad.vantage in goods trade , and the fact that resource-intensive products are more competitive than complementary. Therefore , this paper proposes strategies to optimize China-ndian trade in goods, including en.hancing inter-governmental coordination on trade, improving the response measures of govermments andenterprises to India's trade remedy actions, and shifting towards the export of capital-intensive products.

To address the issues of multi-source coupling, noise interference and insufficient frequency-domain characteristics in process data, this paper proposes a multi-channel fusion prediction model based on time series correlation and frequency-domain enhancement, termed MTS-MCF. The Pearson correlation coefficient method was used to screen input variables, and a time series correlation network (CorNet) was constructed to achieve dynamic label propagation. The coupling weights of parameters were quantified using a frequency-domain enhanced channel attention mechanism (FECAM), and the network response was optimized with the ELU activation function. Experimental results show that compared with the benchmark models, the proposed model reduces MAE for gold and silver by more than 5.7%, reduces MSE by more than 6.3%, and increases   by more than 6.3%, outperforming mainstream models such as MTS-mixers and providing effective technical support for production control.

This study systematically analyzes the current status and evolutionary context of green mine construction in China, exploring pathways for deep decarbonization of the mining industry. Through policy text analysis and typical case studies, it reviews the development of the green mine standard system and constructs a full-chain carbon footprint accounting model covering the "exploration-mining-processing-restoration" lifecycle using the Life Cycle Assessment (LCA) method. The research innovatively proposes a three-dimensional collaborative technical framework of "resources-energy-carbon sink", integrates new quality productivity elements such as intelligent sorting and digital twins, and designs an integrated transformation model comprising "green mining+clean energy substitution+carbon capture, utilization, and storage". TheResults show that: 1) China has initially established a multi-level green mine policy system, but regional economic development imbalances lead to significant differences in implementation outcomes, restricting the carbon peak process; 2) clean energy substitution (e.g., photovoltaic, green hydrogen) and solid waste recycling can reduce the mine carbon emission intensity by more than 30%, serving as core decarbonization pathways before carbon neutrality; 3) as a key support for deep decarbonization, CCUS technology currently faces bottlenecks of high costs and insufficient large-scale deployment, which need to be overcome through green hydrogen coupling and carbon market linkage mechanisms. Based on these findings, the study suggests improving national standards for carbon footprint accounting, establishing a fiscal-carbon market linkage mechanism for CCUS, and accelerating the deep integration of intelligent technologies with mining scenarios, thereby building a new green mine development paradigm driven by "policy guidance, technology impetus, and market regulation". The research results not only provide technical support and institutional guarantees for China's mining industry to achieve carbon peak and carbon neutrality, but also offer a Chinese solution for the global low-carbon transformation of the mining industry.

Efficient Synchronous Leaching of Ga, Ge and In from Zinc Smelting Electric Furnace Slag ＹＡＮＧＺｈｉｈｏｎｇ１, ＬＩＹｏｎｇｊｉａ１, ＹＥＦｕ２, ＺＨＡＮＧＪｉｎｌｉａｎｇ１、２ HPMug2oMmNrOfxWQHLiEksa6s0hFu9Ox348d7QefarYlaFR5ArkhOwm3Da1pmxmxCtenj1+6luWD#r#n+EPn9L6Ce+9onqnMlT+i    2026, 42 (1): 10-.   DOI: 10.3969/j.issn.1009-0479.2026.01.002 Abstract （26）      PDF（pc） （1436KB）（10）       Knowledge map    Save Gallium (Ga), germanium (Ge), and indium (In) are rare dispersed strategic metal elements that are difficult to extract due to their lack of independent mineral deposits and low natural abundance. However, because of their affinities for iron and sulfur, Ga, Ge, and In are commonly associated with sphalerite and other sulfide minerals. During pyrometallurgical or hydrometallurgical zinc processing, trace amounts of these elements become enriched and remain in the slag. In this study, zinc electric furnace slag with relatively high contents of Ga, Ge, and In was used as the raw material. The leaching behavior of Ga, Ge, and In was investigated under various leaching systems (sulfuric acid and hydrochloric acid systems) by examining the effects of temperature, acid concentration, oxidant type, and oxidant dosage. The results showed that Ga, Ge, and In achieved leaching rates of 97.51%, 94.58%, and 98.73%, respectively, in the optimized two-stage hydrochloric acid oxidation leaching process. Furthermore, XRD and SEM analyses revealed that the high lead content in the raw material led to the formation of insoluble lead sulfate in the sulfuric acid system, which encapsulated the particles and inhibited the leaching of Ga, Ge, and In. In contrast, in the hydrochloric acid system, lead chloride forms coordination complex reactions, which redissolve the precipitated lead chloride. This effect effectively eliminates the particle encapsulation barrier and realizes the efficient and synchronous leaching of Ga, Ge, and In, providing a feasible technical route for the extraction and utilization of scattered metals.der complexation, leading to the dissolution of lead species and effectively preventing encapsulation. As a result, efficient and simultaneous leaching of Ga, Ge, and In was achieved, providing a promising approach for the extraction of these strategic metals from zinc smelting residue Related Articles | Metrics | Comments（0）

Linear programming is a more traditional approach characterized by simple program structure and a strong focus on procedural flow. However, it often results in a bloated main program, disorganized functional logic, and poor readability and maintainability of the code. Modular programming emphasizes functional independence and modular invocation, featuring clear program structure as well as improved code maintainability and reusability. In multi-channel temperature control system based on MCU, modular programming can be applied to functional modules such as temperature detection, temperature display, and time-delay operations. This approach ensures that each functional module maintains its operational independence while retaining connectivity with other functions, thereby resulting in a more systematic and rational program design.

Firstly, an objective function based on minimum envelope entropy is constructed, and a VMD signal decomposition method incorporating Sparrow Search Algorithm (SSA) is proposed to achieve adaptive decomposition of the original signal. Secondly, the square envelope spectrum kurtosis is selected as an indicator to screen and reconstruct the VMD decomposition components, thereby removing most of the noise burrs from the original signal. Then, considering the sensitivity of the mean to the overall trend variation of vibration signals, a signal processing method based on improved M-SVD isdesigned by combining the mean singular value with sample entropy. Finally, envelope demodulation is performed on the signal processed by improved M-SVD to extract the weak fault features of the planetary gearbox. Using SNR and RMSE as quantitative metrics, the proposed method is compared with the standalone SSA-VMD, the improved M-SVD, and the original M-SVD methods in pitting fault feature extraction experiments. The proposed method effectively suppresses noise components while maximizing the retention of fault feature information. Related Articles | Metrics | Comments（0）

The feasibility of manganese tailings concrete (MC concrete) was investigated through mix design, performance testing, and heavy metal leaching toxicity analysis. The experimental results show that: 1) The manganese tailings slag aggregate complies with the Class III requirements of GB/T14684—2022 and GB/T14685—2022. 2) Under full aggregate replacement, the workability of MC is comparable to that of natural aggregate concrete, and its 28-day compressive strength reaches 43.62 MPa. Moreover, it effectively immobilizes heavy metals, resulting in low leaching and minimal environmental impact. 3) Through this approach, critical issues associated with industrial waste disposal and natural resource exploitation can be addressed. The overall cost is reduced by 40%～50%, and the exploitation of natural resources is correspondingly reduced, contributing to the green, environmentally friendly, and economically sustainable development strategy of "carbon peak and carbon neutrality".

This method employs dibenzothiophene (DBT) as a model sulfide, H₂O₂ as a green oxidant, and methanol as an extractant to achieve efficient desulfurization under mild conditions. The UiO-66-NH₂ catalyst, featuring high crystallinity and regular polyhedral morphology, was successfully synthesized via a solvothermal approach. Experimental studies investigated the effects of catalyst loading, reaction temperature, oxygen-to-sulfur ratio (O/S), and reaction time on desulfurization efficiency. Results indicate that under optimal conditions: 0.1 g catalyst loading, 60 ℃ reaction temperature, an O/S molar ratio of 4, and 180 min reaction time, DBT desulfurization exceeds 99%. The synergistic action of amino functional groups and Zr-oxo clusters promotes H₂O₂ activation to generate hydroxyl radicals (·OH). Concurrently, the material’s porous structure enhances the synergistic effects of sulfide adsorption and oxidation. This process offers advantages such as mild reaction conditions, elimination of hydrogen requirement, and environmental friendliness, providing an efficient, low-energy-consumption green pathway for achieving deep fuel desulfurization.

During mine production, to extract ores below the water table, it is usually necessary to pump anddrain stope gushing water. Changesin the groundwater level will inevitably affect slope stability. Based onthis, this paper takes the the open-pit slopes of Jianshan Phosphate Mine as the research object, and con-ducts a comparative analysis of the stability of the current slopes of typical cross-sections, current slopeswith accumulation water drained, designed final slopes, and designed final slopes under groundwater-freeconditions. The results indicate that under the condition of accumulated water at the slope toe, the over-all slope safety factor of the mine's current slopes is relatively high, providing favorable conditions forsubsequent design and mining work. During the accumulated water pumping and drainage in the earlystage of current slope mining, the slope safety factor decreases slightly. due to the hydrostatic and hydro-dynamic pressures acting on the slopes. During mine production, mechanical pumping and drainage ofmining area gushing water will affect the stability of the open-pit slopes to a certain extent. The designedfinal slopes in the research area have high safety reserves, enabling normal production operations in themine. Meanwhile, a comparison with the stability of the final slopes without groundwater influence showsthat groundwater has a significant impact on stope slope stability. Therefore, during mining, when pumping and draining mining pit gushing water, certain slope treatment and disaster prevention and control measures must be adopted for high and steep slopes.

How to quickly acquire high-precision normal height has be-come one of the recent research topics in the field of surveying and mapping. This article proposes aGNSS elevation filtting method that considers two global gravity field models, namely EGM2008 and SGG-UGM-2. First, the gravity field model is used to generate gravity quasi-geoid; then a difference surface isgenerated based on the measured data and the gravity field model. Finally, the difference surface is fusedwith the gravity quasi-geoid to fit the gravity quasi-geoid to the actual quasi-geoid, thereby achieving thepurpose of correcting the gravity field models using the elevation anomaly points. In this paper, theEGM2008 and SGG-UGM-2 gravity field models are used, and the refined quasi-geoid model of YunnanProvince is adopted for accuracy verification. The test results, show that this method is stable and relia-ble, and can meet the requirements of common applications such as large-scale topographic mapping.

Identification of Gemological and Spectral Characteristics ofNatural and Synthetic Spinels#br# XIE Jie HPMug2oMmNrOfxWQHLiEksa6s0hFu9Ox348d7QefarYlaFR5ArkhOwm3Da1pmxmxCtenj1+6luWD#r#n+EPn9L6Ce+9onqnMlT+i    2025, 41 (05): 1-.   DOI: 10.3969/j.issn.1009-0479.2025.05.010 Abstract （55）      PDF（pc） （1318KB）（5）       Knowledge map    Save  As spinels have gained increasing popularity in international colored gemstone trading, a largenumber of "high-quality" synthetic spinels have become available. Inspectionshave revealed that, besidesthe common blue varieties synthesizedby the flame fusion method, these synthetic spinels also include newred-pink varieties synthesized by the Czochralski method, which are indistinguishable from natural spinels.Conventional gemological identification instruments, including Fourier transform infrared (FTIR) spectrom-eters and ultraviolet-visible (UV-Vis) spectrophotometers, were employed to analyze the gemological prop-erties and spectral characteristics of both natural and synthetic spinel samples. Research indicates that thegemological properties of synthetic spinels closely resemble those of spinels, and identifying typical internalinclusions is the key to identification. Infrared (IR) spectroscopy revealed that spinels exhibit three ab-sorption peaks at 543, 590, and 732 cm "1, whereas flame fusion-synthesized spinels exhibit three absorp-tion peaks at 547, 725, and 844 cm~1. Testing revealed that Czochralski-synthesized spinels lack the ab-sorption peak at 590 cm-1 found in spinels, exhibiting only two absorption peaks at 547 and 748 cm~1This evidence serves as a significant identification characteristic for Czochralski-synthesized spinels. UV-Vis spectroscopy indicated that red spinels and Czochralski-synthesized spinels are colored by chromium,blue spinels by iron, and blue flame fusion-synthesized spinels by cobalt. Hence, to effectively differentiate spinels from synthetic spinels in practical testing, it is necessary to combine spectral characteristics. Related Articles | Metrics | Comments（0）
