Stress measurement plays a crucial role in geomechanics and rock engineering, especially for the design and construction of large-scale rock projects. This paper presents a novel method, based on the traditional stress relief approach, for indirectly measuring rock stress using optical techniques. The proposed method allows for the acquisition of full-field strain evolution on the borehole's inner wall before and after disturbance, facilitating the determination of three-dimensional (3D) stress information at multiple points within a single borehole. The study focuses on presenting the method's theoretical framework, laboratory validation results, and equipment design conception. The theoretical framework comprises three key components: the optical imaging method of the borehole wall, the digital image correlation (DIC) method, and the stress calculation procedure. Laboratory validation tests investigate strain field distribution on the borehole wall under varying stress conditions, with stress results derived from DIC strain data. Remarkably, the optical method demonstrates better measurement accuracy during the unloading stage compared to conventional strain gauge methods. At relatively high stress levels, the optical method demonstrates a relative error of less than 7% and an absolute error within 0.5 MPa. Furthermore, a comparative analysis between the optical method and the conventional contact resistance strain gauge method highlights the optical method's enhanced accuracy and stability, particularly during the unloading stage. The proposed optical stress measurement device represents a pioneering effort in the application of DIC technology to rock engineering, highlighting its potential to advance stress measurement techniques in the field.

磷酸根、植酸等含磷化合物共沉淀可阻碍水铁矿的相转化,改变水铁矿的纳米孔隙结构,但其对水铁矿吸附有机化合物行为的影响尚不清楚.本文将正磷酸、植酸和DNA加入Fe3+化学沉淀过程,得到了系列P/Fe比例的含磷2-线水铁矿,测试了水铁矿的组成结构、Fe(II)催化转化及对土霉素等抗生素、单宁酸等有机酸的吸附作用.结果表明,正磷酸共沉淀、植酸共沉淀和DNA共沉淀使水铁矿颗粒中直径为7~100 nm的孔体积增加,缓解了水铁矿通过Fe(II)催化向针铁矿和纤铁矿的转化.由于水铁矿表面正磷酸、植酸的络合位点和土霉素、单宁酸(特别是羟基)络合位点存在较大差异,正磷酸根共沉淀、植酸共沉淀对水铁矿表面的占据对富含羟基的土霉素和单宁酸的吸附位点影响相对较小,但通过缓解水铁矿团聚、促进孔体积和孔填充(或多层吸附)最终使化合物吸附能力增强.水铁矿表面磷酸、植酸、DNA与头孢克肟、水杨酸、邻苯二甲酸、腺苷单磷酸(特别是羧基和磷羟基)的络合位点显著重叠,正磷酸共沉淀、植酸共沉淀和DNA共沉淀占据了水铁矿表面吸附位点并最终导致吸附的急聚降低.这些结果丰富了磷共沉淀对水铁矿吸附抗生素和天然有机酸影响的认识,可为土壤中铁矿物对有机污染的缓解和有机质的保护提供参考.

儿童慢性病是指发生在0~18岁之间,持续时间超过3个月或3年中发生3次及以上的慢性非传染性疾病[1]。近年来,由于人们生活方式的改变和医学技术的发展,一些原本急性致命性的疾病逐渐转变为慢性病,导致儿童慢性病的患病率逐年上升。国外儿童慢性病的患病率是过去40年的4倍,占全部儿童的12%~16%。而在中国,儿童慢性病的发病率更是达到10%~20%[2]。儿童慢性病已成为全球广泛关注的公共卫生问题之一[3]。

为了研究政府及零售商的农产品供应链帮扶决策,考虑政府生产性补贴和零售商投入的扶贫努力,建立3种订单农业帮扶模型,包括政府补贴模型(GS模型)、零售商扶贫模型(RH模型)、政府与零售商联合帮扶模型(GR模型)。通过对3种模型中各主体利润关系及利润增量的对比分析,得到政府及零售商的最优帮扶决策。结果表明,政府仅为高成本农户提供生产性补贴之后,零售商有必要为其投入扶贫努力;零售商为所有农户投入扶贫努力之后,政府有必要再提供生产性补贴。零售商的扶贫助农计划可以始终惠及所有农户,而在消费者强敏感市场下,政府后期提供补贴可以惠及所有农户。此外,在消费者弱敏感市场下需要政府先补贴,零售商后投入扶贫努力;在消费者强敏感市场下需要零售商先投入扶贫努力,然后政府再补贴。

A plant bio-electrochemical system(PBES) was constructed for organic pollutant removal and power generation. The bio-cathode, composed of granular activated carbon(GAC), stainless wire mesh and a plant species(Triticum aestivum L.), was able to catalyze cathodic reactions without any requirement for aeration or power input. During the 60-day-long operation, an average voltage of 516 m V(1000 Ω) and maximum power density(Pmax) of 0.83 W/m^3 were obtained in the PBES. The total nitrogen removal and total organic carbon removal in the PBES were 85% and 97%, respectively. Microbial community analyses indicated that bacteria associated with power generation and organic removal were the predominant species in the bio-cathode, and plant-growth-promoting rhizobacteria were also found in the PBES. The results suggested that the coupling of plants with the GAC cathode may enhance the organicmatter degradation and energy generation from wastewater and therefore provide a new method for bio-cathode design and promote energy efficiency.
