Biomethane has been developed rapidly in many countries as a renewable energy which upgraded from biogas. China also began to pay attention to it even though we still at a initial stage, primarily, understanding the hiomethane potential and development prospect, choosing appropriate biomass as the biomethane source is very important. In this work, the theoretical and practical biomethane producing potential from five main bio- mass resources in China were estimated with appropriate methods based on the data collected, and during cal- culation, two appropriate energy crops were assumed to be planted on marginal lands for biomethane production. Our estimation showed that the theoretical and practical biomethane potentials in China can reach to 888.78 and 316.30 billion m3 per year, agricultural waste should be the preferential development biomass, and planting energy crops on marginal lands is the most promising way to enhance biomethane production in China. Finally, biomethane is compared with natural gas, and the result showed that 48.15% of the practical biomethane potential can meet the total Chinese natural gas consumption in 2013.

Modularized construction is a new type of prefabricated building system with green environmental protection and excellent performance. There are few studies on the seismic performance of its key connection joint. This paper presents a new type of assembled connection joint for the high-rise modularized construction. Cyclic shear tests of full-scale joints were carried out, and the key indexes of their seismic performances including the hysteretic performance, ductility, and energy dissipation capacity were analyzed and obtained. The results show that the hysteresis loops of longitudinal and lateral cyclic shear tests were both plump in shapes. The ductility coefficients were 4.54 and 4.98, and the energy dissipation coefficients were 1.83 and 1.43, respectively. The test joint had good ductility and energy dissipation capacity. The positions of yield failure of specimens were mainly concentrated in the connection areas between the column and short beam or end-plate. The research can provide the technical reference for the seismic design and engineering application of related modularized constructions.

A mathematical model based on Fick's first lawwas established to describe the process of ultrasonic-assisted extraction of arctigenin from acid hydrolyzed *** hydrolization with hydrochloric acid promotes the conversion of arctiin to arctigenin in the arctiin-rich active pharmaceutical ingredient, and the hydrolyzed products were further examined to investigate the process setup. By considering the mechanism of the extraction process and experimental data, the effects of parameters including solven to solid ratio, particle size of hydrolyzed samples, ethano volume fraction, ultrasound power, extraction temperature and extraction time on concentration of arctigenin were analyzed in detail. The model was suitable for simulating the process of ultrasonic-assisted extraction of arctigenin. The simulation results of the model agree well with experimental data with the deviation below13%, indicating that the mathematical mode can provide valuable guidance for the extraction of arctigenin from acid hydrolyzed FructusArctii.

针对我国待建的110 m全可动射电望远镜(QTT)的工作特点,以提高主反射面精度为目标,以最佳吻合抛物面为拟合标准,分析了传统结构方案致使精度较低的本质原因为反射体变形不均匀,主要源于如下三方面:主反射面存在集中荷载作用、背架结构支承方案不合理、背架结构体系空间受力性能不佳。基于此,改变副反射面撑腿坐落位置,对背架结构采用三角锥、四角锥相结合的网架式结构方案,并对其引入一种高度极对称的伞撑式支承方案。最终提出的全可动望远镜结构总体方案显著提高了主反射面精度,其RMS最大值可降至0.306 mm;相较目前世界最大的全可动射电望远镜GBT而言,其反射面积增大了10%,精度提高了12.6%,自重降低了40%,其研究成果达到国际先进水平。

所谓"品格调查制度",是指为了在刑事程序上对每一个犯罪人都能选择恰当的处遇方法,使法院能在判决前的审理中,对被告人的素质和环境做出科学的分析而制定的制度。在我国,这种品格调查仅适用于未成年人犯罪案件中。目前我国女性犯罪日益突出,犯罪群体逐年增大。而女性犯罪同未成年人犯罪一样有特殊的心理、生理、社会等原因,同样需要给予更多的关注,在女性犯罪案件中适用品格调查具备正当性基础,具有相当的可行性。我国可以通过立法对品格调查的主体及内容、品格调查报告在诉讼中的具体运用规则进行规定,以规范司法实务部门的实际操作。
