Hierarchical core-shell-like MnO2 nanostructures （NSs） were used to anchor MnO2 hexagonal nanoplate arrays （HNPAs） on carbon cloth （CC） fibers. The NSs were prepared by a novel one-step electrochemical deposition method. Under an external cathodic voltage of -2.0 V for 30 min, hierarchical core-shell-like MnO2-NS-decorated MnO2 HNPAs （MnO2 NSs@MnO2 HNPAs） were uniformly grown on CC with reliable adhesion. The phase purity and morphological properties of the samples were characterized by various physicochemical techniques. At a constant external cathodic voltage, growth of MnO2 NSs@MnO2 HNPAs on CC was carried for different time periods. When utilized as a flexible, robust, and binder-free electrode for pseudocapacitors, the hierarchical core-shell-like MnO2 NSs@MnO2 HNPAs on CC showed clearly enhanced electrochemical properties in 1 M Na2SO4 electrolyte solution. The results indicate that the MnO2 NSs@MnO2 HNPAs on CC have a maximum specific capacitance of 244.54 F/g at a current density of 0.5 A/g with excellent cycling stability compared to that of bare MnO2 HNPAs on CC （112.1 F/g at 0.5 A/g current density）. We believe that the superior charge storage performance of the pseudocapacitive electrode can be mainly attributed to the hierarchical MnO2 NSs@MnO2 HNPAs building blocks that have a large specific surface area, offering additional electroactive sites for efficient electrochemical reactions. The facile and single-step approach to growth of hierarchical pseudocapacitive materials on textile based electrodes opens up the possibility for the fabrication of high-performance flexible energy storage devices.

Landslides are natural disasters which can pose a serious threat to human and property in many areas around the world. The Transient Rainfall Infiltration and Grid-based Regional Slope-stability (TRIGRS) model was used to investigate the rainfall-induced shallow landslides in a forested mountain region, Korea. Various input data for TRIGRS model include time-varying rainfall, topographic characteristics, soil depth, material strength, and hydraulic properties. A series of calculations were conducted in determining the slope stability over the Jangheung region in Korea during the storm occurred on August 6, 1998. The results show that TRIGRS model captured about 64.1% of landslides that were extracted from the IKONOS2 imageries. The model demonstrated how the factor of safety changed with time during a storm considering both the transient and spatial responses of pore water pressure in its slope stability calculation.

为了进一步提高脉冲爆震发动机(PDE)的推进性能,对PDE使用流体喷管模型进行了多循环数值模拟研究,并提出了主次流错相位喷注方案。结果表明:主次流错相位喷注方案不仅可以调节主流和二次流的有效流通面积,改善喷管的非设计点状态,而且可以提高爆震室内可燃气最终充填压力,增强爆震燃烧强度;在主次流错相位喷注方案下,喷管主流进口瞬时气流总压相对喷管设计点的离散程度明显下降,有效改善了喷管的非设计点状态;最佳的主次流相位差为反传压缩波恰好传播至爆震室头部这一工况,最佳的二次流喷注位置为喷管喉部;相比基准喷管的最大比冲性能,PDE使用流体喷管可以产生5.64%的比冲增益。

20世纪初,全国农业农村蔓延的衰落情势引发了知识界团体对于救济农村的广泛社会行动。其后,全国各地域乡村工作者一致有意成立一个全国乡村服务人员的联合组织。1933年、1934年、1935年连续三年,在梁漱溟、晏阳初、黄炎培、章元善等人努力操持下,先后召开了三次全国乡村工作会,参会团体和参会代表覆盖全国南北各地,中央党部,中央政府农业、教育、金融等部,地方政府、媒体及外国人士多有参加,影响声势浩大。然而,在当时形势下,全国乡村工作讨论会却始终维系着一种松散的联合体的状态,没有在官方注册为一个合法社团。各个乡建团体基于不同的政治环境立场出发对中国问题的认识不同,在乡村改进的解决路径、追求目标、工作侧重点、运营机制等方面有着诸多分歧,很难对整体的乡建运动有一个整体的把握和方向性的推动。乡建工作的“孤岛”现象依然没有改变。

传统刑法理论认为,公共场所是指公众的身体可以自由出入的场所,即应当具有现实性或者物理性。但在当前传统犯罪网络异化的背景下,网络空间中的行为同样可以造成实际损害,网络空间秩序亦被包含在了公共秩序中,身体自由进入说的判断标准早已不合时宜。宏观来看,“网络空间”与“公共场所”并非刑法上的专有名词,互联网的迭代升级也不只触及法律领域,因此有必要借助社会学、传播学的视野来帮助我们厘清公共场所的本质属性。同时以性侵案件作为样本分析可知,网络直播性侵行为具有加重处罚的必要性,实践中强奸、猥亵他人并直播的情形,应当认定行为人是在“公共场所当众”实施,从而适用该加重情节。
