以微米级B4C粉体为原料,通过与TiO2和葡萄糖原位反应制备TiB2颗粒增韧B4C复合材料。研究了烧结温度和烧结助剂对材料烧结行为及力学性能的影响。在1950℃反应热压下获得了相对密度为97.7%的TiB2/B4C复合材料,断裂韧性达到5.3 MPa.m1/2。添加Al2O3和Si烧结助剂后,分别在1950℃和1900℃获得了接近致密的(TiB2,Al2O3)/B4C和(TiB2,SiC)/B4C复合材料,断裂韧性分别提高到7.09和6.35 MPa.m1/2。显微组织分析表明,增韧作用主要来自残余应力引起的裂纹偏转。

Located at the northeastern margin of the Tibetan plateau,the Ordos block is a stable tectonic unit in North *** its active boundary fault zones,the Ordos block played an important role in the eastward extrusion mechanism of the Tibetan *** University deployed a linear array of 15 portable broadband seismometers across the western Weihe graben during September 2005 to August 2006 and later a 2-D seismic array（Southwest Ordos Array） of 14 portable broadband seismometers during 2007-2008 at its southwestern *** of shear wave splitting of SKS and SKKS phases at these stations show that the fast directions trend ～110° with an average delay time of 0.9 s in the southwestern margin of the Ordos *** agreement between the lithosphere deformation indicated by GPS data and Quaternary fault slip-rate observations and the mantle flow represented by shear wave splitting implies that accordant deformation patterns from lithosphere to asthenosphere in relation to the eastward extrusion of the Tibetan plateau could extend at least to 200 km *** distribution of splitting polarization directions indicates that the mantle flow driven by the Tibetan plateau is blocked by the Ordos block and locally restricted in a narrow channel along the Qinling-Dabie fault zones between the Ordos block and Sichuan basin.

Volatile organic compounds(VOCs)and particulate matter(PM)are both frequently present in air as contaminants,posing serious health and environmental *** current filtration of VOCs utilizes entirely different materials compared with PM filtration,adding complexity to air cleaning ***,we design a pitch-based activated carbon ultrathin fibers(PACUFs)for bifunctional air *** PACUFs,with fiber diameter of∼1.2μm and specific surface area of 2341 m^(2) g^(−1),provide both high VOCs adsorption capacity(∼706 mg g^(−1))and excellent efficiency of∼97% PM_(0.3) filtration with low pressure *** contrast,traditional activated carbon fibers exhibit VOCs adsorption capacity of∼448 mg g^(−1) and PM_(0.3) removal efficiency of only∼36%at an equal area density of∼190 g m^(−2).Theoretical investigations reveal the filtration mechanism of the high-performance bifunctional fibrous PACUFs,considering full advantages of the high surface area,small pore size,and significant micropore volume.

为了解决煤矿井下电缆火灾自动探测与灭火的问题,采用理论分析和实验的方法,研究了一种分布式光纤测温与ZigBee通讯控制的超细干粉灭火技术相结合的煤矿电缆火灾自动监控系统。在依兰煤矿进行的应用实践表明,该系统采用光纤自发拉曼(Raman)散射效应与光时域反射(OTDR)技术可以实时准确探测煤矿电缆不同位置的温度并定位火灾位置,通过ZigBee无线通讯网络控制灭火装置快速自动处置。该成果突破了煤矿电缆火灾点式监测及不能快速自动灭火处置的传统模式,可以有效防止煤矿电缆火灾发生。

The Chinese-German Journal of Clinical Oncology 2009年第6期8卷 366-368页

Primary choriocarcinoma of the uterine cervix (PCC) is an extremely rare disease. The conventional treatment of PCC is a combination of hysterectomy and chemotherapy. We present one rare case proved by cervical biopsy. The patient was an 36-year-old Chinese woman with irregular vaginal bleeding for 60 days. A cervical tumoral mass was seen in the pelvic examination and biopsy revealed active hyperplasia of trophoblastic cell. Because of massive vaginal haemorrhage, the patient accepted uterine artery drug pouring and embolism emergently. This management had gained a satisfactory effect. Thus, Uterine artery drug pouring and embolism is one new and effective weapon for PCC, which can preserve the patient’s productive ability.

A series of samples of hexagonal boron nitride-aluminum nitride ceramic composites with different amounts of CaF2 as sintering aid were prepared by spark plasma sintered at 1700-1850 ℃ for 5 *** addition of CaF2 effectively lowered the sintering temperature and promoted the densification of AlN-BN *** the increase of sintering temperature,the density increased,and the contiguity of AlN grains enhanced in AlN-BN *** conductivity of AlN-BN composites increased with the increase in CaF2 content and sintering temperature,and there is a maximum value of 78.6 W·m^-1·K^-1 when the sample with 3wt% CaF2 sintered at 1800 ℃.

以ChatGPT为代表的生成式AI依托于海量的训练数据来实现模型的迭代升级,训练数据的质量和数量直接决定着生成式AI的性能和泛化能力。然而,训练数据本身潜藏着来源合法性、质量可信性、规模偏离性等风险,自我规制与政府规制路径都难以契合生成式AI的市场布局与更迭速度,亟须在包容审慎理念下对生成式AI训练数据予以元规制。在元规制理念下,国家通过规范引导模型研发者将经设计的数据保护与科技伦理理念内嵌于生成式AI的训练数据中,促成数据保护从利用环节延伸至研发环节,通过可信的数据来源、数据分类分级、数据影响评估等措施促成模型研发者自我观照式的内省,并经由数据保护的监管沙盒实现自我规制的规制。

工具理性的知识移植与抽离的知识实践窄化了社会工作实践者的行动空间,使得身处复杂社会现场的实践者难以“自觉觉他”,陷入社会工作实践的知识困境。社会工作的实践自觉成为摆脱知识困境的有效处方。社会工作实践自觉是社会工作实践者与研究者在社会工作实践(行动研究)过程中对服务人群生命细致变化的辨识能力,以及对实践场景探究的自觉性,同时也是社会工作实践者与研究者具有主体能动性的社会探索过程,以及对实践的经验审视与实践知识生产的历程。社会工作实践自觉承载了理论与实践之间来回修正的辩证关系,是一个循环往复、求真求实的辩证过程。新时代中国社会工作实践自觉应以西方经验为他山之石,以中国本土经验为土壤,立足本土社会历史情境及实践者的主体性,遵循实践取向的知识发展路径,迈向中国社会工作本土实践知识的生产。
