中国特色高等教育话语体系本质上是一种坚持民族理想、推动国家治理、促进知识发展、开展对外交流的关系性实践。百年来,中国高等教育发展历经萌芽期、探索期、发展期和成长期,形成了以“救国”“革命”“改革”“复兴”为代表的高等教育话语体系。本土化是中国特色高等教育话语体系逐渐成形的关键线索,民族图像的大众化、国家权力的人民性、知识建构的自主性以及对外交流的平等性则在话语主体、话语权力、话语知识、话语秩序四个方面构成其核心要义。中国特色高等教育话语体系通过提升话语主体的民族自信、夯实话语意识形态的思想根基、提升高等教育的治理效能、激发话语知识的内生动力、重塑话语秩序的国际格局以推动中国高等教育本土化转型,不断形成具有中国现代性的高等教育理论与实践体系,全面增强中国特色高等教育话语体系的理论概括力、实践生命力、现实感召力和国际影响力。

Paeoniae Radix Rubra (PRR) is a commonly used traditional Chinese medicine known for promoting blood circulation and alleviating pain. Stir-frying PRR with rice wine enhances its effectiveness in improving blood flow and resolving stasis. To explore the pharmacodynamic basis and mechanisms behind PRR's anti-thrombotic effects—both pre- and post-stir-frying—a comprehensive approach combining pharmacological research， metabolomics， and chemistry was employed. Fraction inter-cross validation experiments， pharmacological assessments， and metabolomic analyses confirm the efficacy of the fraction separation process. Wine-stir-fried PRR (WPRR) shows superior blood activation compared to PRR. PRR mainly affects the TCA cycle and sphingolipid metabolism pathways through its small molecules， enhancing coagulation and fibrinolysis systems' functionality. All the subdivided components of WPRR have anti-thrombotic effects， especially polysaccharides and oligosaccharides. WPRR improves thrombotic conditions in rat blood stasis by modulating arachidonic acid metabolism， TCA cycle， lipid status enhancement， and angiogenesis stimulation while regulating platelet adhesion and aggregation. In conclusion， compared with PRR， the main material basis for the blood-activating efficacy of WPRR has transformed from small molecule compounds to polysaccharide and oligosaccharide components. The action pathways of WPRR in exerting anti-thrombotic efficacy have increased. The polysaccharide components in WPRR might possess considerable potential for being developed into natural anti-thrombotic drugs.

As humans and robots work closer together than ever, anthropomorphic robotic arms with intuitive human-robot interaction interfaces have drawn massive attention to improving the quality of robot-assisted manipulation. In pursuit of this,we designed a dedicated 7-degrees-of-freedom (DoF) anthropomorphic robotic arm having three compact differential joints and a head-mounted gaze tracker enabling head-pose-tracked 3D gaze estimation. Moreover, two key challenges were addressed to achieve accurate robot-assisted manipulation of the object indicated by the direction of human gaze. First, a novel predictive pupil feature was proposed for 3D gaze estimation. Differing from most existing features subjected to the common paraxial approximation assumption, the proposed novel predictive pupil feature considered the light refraction at two corneal surfaces with a more realistic eye model, significantly improving the 3D gaze estimation accuracy when the eyeball rotates at large angles. Second, a novel optimization-based approach was developed to efficiently compensate for the posture errors of the designed 7-DoF anthropomorphic robotic arm for accurate manipulation. Compared with the existing Jacobian-based or optimization-based approaches with nominal joint values as iteration initial, the proposed approach computed the optimal iteration initial and realized faster convergence for real-time posture error compensation. With the posture error compensation in real time and 3D gaze estimated accurately, the human can command accurate robot-assisted manipulation using his eyes intuitively. The proposed system was successfully tested on five healthy subjects.

Developing a bridge capping layer between perovskite and hole transport layer materials（HTMs） in the n-i-p perovskite solar cells（pero-SCs） is an effective approach to modify the morphology of HTMs and passivate the perovskite ***, we select the quinoxaline-based bifunctional passivation agent, quinoxalin-6-yl-methylamine hydrochloride（Qx MACl）,as the bridging layer, and a D-A copolymer PBQ12 containing the same quinoxaline unit as an HTM for the n-i-p pero-SCs. Due to the π-π stacking among the common quinoxaline units in the bridge layer and HTM, Qx MACl induces the π-π stacking of the PBQ12 film and improves the film morphology of HTMs with better conductivity. Additionally, Qx MACl can effectively passivate the perovskite surface, and PBQ12 possesses appropriate energy levels and high hole mobility. The pero-SCs based on FAPbI3with PBQ12/Qx MACl treatment showed a higher power conversion efficiency（PCE） of 24.05% and outstanding stability, maintaining 95.4% and 92.1% of its initial PCE after 750 h of storage and after over 800 h of thermal annealing at 85 °C, respectively. To further enhance the PCE of the PBQ12/Qx MACl-based devices, we developed a non-metal ion dopant for the PBQ12 HTM. Through trace doping of PBQ12 HTM by the non-metal ion dopant, the PCE of the PBQ12/Qx MACl-based devices reached 25.24%（the calibrated PCE of 24.55% by the National Institute of Metrology, China）.

Lead halide perovskite quantum dots（LHP QDs） have been revealed to possess great potential in photocatalytic applications including CO2reduction, which however suffer from poor stability. Herein, a high crystalline hydrazine-linked three-dimensional（3D） covalent organic framework, USTB-17, was fabricated from the reaction between 12-connected building block and 4-connected 3,5,7-tetrakis（4-aldophenyl）-adamantane. Post-modification with Ni2+affords the metallic framework USTB-17（Ni）followed by sequential deposition of the CH3NH2PbI3（MAPbI3） perovskite QDs into its pores, generating the USTB-17（Ni）@MAPbI3composite. Powder X-ray diffraction analysis together with theoretical simulations and transmission electron microscopy discloses the crystalline nature of USTB-17, USTB-17（Ni）, and USTB-17（Ni）@MAPbI3with an unprecedented noninterpenetrated hpt topology. The close contact of QDs inside the COF pores with the Ni catalytic site locating at the pore surface of COF allows a rapid transfer of the photogenerated electrons in QDs to the Ni catalytic sites, enhancing the photocatalytic activity for CO2reduction. This endows USTB-17（Ni）@MAPbI3with efficient photocatalysis performance for photocatalytic CO2reduction with CO generation rate of 365 μmol g-1h-1and CO selectivity up to 96% under visible-light irradiation, 7 times higher than that of USTB-17（Ni）. After four cycles of reactions, the photocatalytic CO generation rate remains almost unchanged, demonstrating its excellent cycle stability.
