A novel fine inclusion removal technology was put forward with dispersed in-situ heterophases induced by the composite sphere explosive reaction. A composite sphere with this function was designed and prepared using a laboratory scale batch-type balling disc （at 12 r/min）, and the composite sphere was fed at the end of the RH refining process. The results indicate that inclusions in the IF molten steel can be removed effectively by feeding composite spheres in RH ladle. Compared with conventional inclusion removal technology, using this novel technology, the amount of oxide inclusions can be decreased to a lower level and the inclusion size becomes finer, the total oxygen content in the as-cast slab can approach 5×10？6, and the cost per ton of steel produced can be reduced by 5-12 Yuan RMB.

Recycling of iron and steelmaking dusts is a key issue in environmental protection efforts and to ensure efficient utilization. In this investigation, we developed a novel recovery process that uses a dispersed in-situ phase induced by an explosive reaction of composite balls of iron and steelmaking dusts. We designed and prepared composite balls for this function using a laboratory model batch-type balling disc(at 12 r/min) and optimized the feeding modes in 180-t and 260-t basic oxygen furnace(BOF) converters. The results indicate that feeding composite balls into BOF converters is an effective novel technology for recovering iron and steelmaking dusts. The period after hot metal charging and prior to the oxygen-blowing process is the most reasonable time to feed composite balls. Composite ball treatment is not appropriate for steel production with sulfur requirements lower than 80 ppm. The maximum composite ball feeding amount is 40 kg/t and the iron yield rate is better than 95%. Compared with the conventional recycling process of sludge and dust, this novel technology is more convenient and efficient, saving up to 309 RMB per ton of steel. further investigation of this novel recycling technology is merited.

儿童对教育的认知关系到其代际流动和自身发展。本研究发现,农民工输出地儿童尽管成长在有着打工传统的社区环境中,但"打工文化"对他们的影响有限,他们中对打工持否定意见的较为普遍,相反却崇尚读书的价值,对学校文化表现出亲和的倾向,这在群体意义上否定了既有相关研究的观点和结论。这一发现有助于洞察农民及农民工地位再生产的机制,同时也可以解释农村儿童失学和弃学现象的真正原因。所以,对农民工输出地的儿童而言,无论其未来的社会流动结果表现如何,"反打工·亲学校文化"将是他们抗拒底层再生产、通过教育实现代际向上流动的一股力量。

The Solar X-ray Detector(SXD) on-board the Macao Science Satellite-1B(MSS-1B) was successfully launched via the Chinese Long March-2C rocket on 21 May 2023, and commenced operations in early June of the same year. The MSS-1B/Soft X-ray Detection Units(SXDUs) employ two silicon drift detectors(SDDs), providing a wide range of energy spectra spanning from 0.7 to 24 keV. Notably, the SXDUs deliver a high-resolution capability of 0.14 keV@5.9 keV and operate with a time cadence of 1 second. Here, we perform thorough calibrations of the MSS-1B/SXDUs, employing a combination of ground experiments and simulations. In addition, quantitative analysis comparing the flux measurements obtained by the MSS-1B/SXDUs to the data collected by the Geostationary Operational Environmental Satellite(GOES), provides compelling evidence of their consistency. furthermore, the preliminary spectral analysis results showcase the robustness and expected performance of the MSS-1B/SXDUs, unlocking their potential for facilitating the study of dynamic evolution of solar flares. Moreover, the innovative MSS-1B/Solar X-ray Detector facilitates concurrent observations of solar soft and hard X-rays, thereby making valuable contributions to the advancements in solar research.

Chili fermentation is one of the most important processes in the production of Pixian Douban (PXDB)， which determines the flavor and product quality of PXDB. However， the maturity of fermented chili mainly depends on empirical judgment， which can not satisfy the need for standardized production of PXDB. Therefore， this study aimed to investigate volatile and non-volatile substances during the maturation process and to find markers related to the maturity of fermented chili. GC×GC-MS combined with multivariate statistical analysis revealed that 2-methoxy-3-isobutyl pyrazine， linalool， 3-(methylthio)propionaldehyde， myrcene， and decanal (ROAV ≥ 1， VIP > 1， P < 0.05) were regarded as potentially active aromatic markers for differentiating fermentation time. Additionally， UPLC-QTOF-MS combined with multivariate statistical analysis resulted that 14 compounds can serve as differentiated non-volatile compounds. The correlation of maturity-related physico-chemical indicators with volatile and non-volatile compounds revealed that three volatile compounds (2-methoxy-3-isobutylpyrazine， linalool， and decanal) along with fructose and adenosine could serve as markers for evaluating the maturity of chili. This study is expected to establish a standard for the determination of maturity the fermented chili and lay the foundation for intelligent production of PXDB.
