摘要：Photocatalytic decomposition of sugars is a promising way of providing H_(2),CO,and HCOOH as sus-tainable energy ***,the production of C_(1)chemicals requires the cleavage of robust C−C bonds in sugars with concurrent production of H_(2),which remains ***,the photo-catalytic activity for glucose decomposition to HCOOH,CO(C_(1)chemicals),and H_(2)on Cu/TiO_(2)was enhanced by nitrogen *** to nitrogen doping,atomically dispersed and stable Cu sites resistant to light irradiation are formed on Cu/TiO_(2).The electronic interaction between Cu and nitrogen ions originates valence band structure and defect levels composed of N 2p orbit,distinct from undoped Cu/TiO_(2).Therefore,the lifetime of charge carriers is prolonged,resulting in the pro-duction of C_(1)chemicals and H_(2)with productivities 1.7 and 2.1 folds that of Cu/TiO_(2).This work pro-vides a strategy to design coordinatively stable Cu ions for photocatalytic biomass conversion.

摘要：目的调查目前我国医疗机构静脉用药调配中心(PIVAS)自动化设备配备情况,为了解PIVAS自动化建设现状及发展方向提供参考。方法以问卷调查的形式,通过“问卷星”平台对全国30个省份的医疗机构PIVAS发放问卷,对PIVAS自动化设备配备情况、智能静脉用药调配机器人配备情况、工作流程软件的设计开发情况和自动化设备信息对接方式4个方面的内容进行调查,并进行统计分析。结果共761个PIVAS参与调研,有373个PIVAS配备了自动化设备。在配备了自动化设备的373个PIVAS中,以配备自动成品输液分拣机和自动贴签机为主,93.56%的PIVAS未配备智能静脉用药调配机器人;511个PIVAS使用第三方软件公司设计开发的工作流程软件;在自动化设备信息对接方式方面,没有自动化设备、自动化设备直接与医院信息系统对接以及自动化设备与PIVAS软件平台对接,这3种情况的占比差距不大。结论我国PIVAS的自动化设备配备率较低,还有很大的发展空间。我国应该尽快完善自动化设备相关指引,促进设备研发规范合理,促使PIVAS更高效地完成静脉用药调配,以提供更完善的药学服务。

摘要：物流活动的空载率居高不下源于路径规划不合理及企业间缺少合作,共同配送是降低空载损失的有效模式,但非集中式共同配送下物流企业可能基于被分派的订单选择自身成本最小的配送路径,从而导致共同配送联盟的空载损失变大。本文研究考虑空载损失的非集中式共同配送订单分派及路径优化,首先提出空载损失定义,权衡整个配送过程的成本最小和空载损失最小两个目标,基于非集中式共同配送的特征设计订单分派策略,进而建立订单分派及路径优化模型。设计了基于ε约束法的精确算法、改进的MOPSO(multiple objective particle swarm optimization)算法、多项式时间快速算法进行求解,并结合算例验证算法的有效性。数值分析结果表明,即使物流企业均追求自身成本最小化,提出的订单分派策略也可得到与全局优化相近的结果。

摘要：The introduction of productive gardens on public building roofs is an active way to use urban idle space. It has ecological, economic, and social values and helps alleviate many urban problems caused by the rapid advancement of land urbanization. This paper takes the productive rooftop garden of an urban commercial complex as an example, and assesses its development status based on methods including ArcGIS, field research, and questionnaire interviews, combined with the overall aspects of the country and key case analysis. The results indicate several key aspects of the current status of such gardens in China.(1) As affected by natural and social factors, the current spatial distribution of productive rooftop gardens of commercial complexes in Chinese mainland is uneven, with 84.21% located in the southeast coast and the Sichuan region.(2) The operation and development of this type of productive landscape is in good shape. The number of rooftop gardens has continued to increase since 2013, and the scale is generally greater. Currently, the business model which combines nature education and parent-child amusement experience activities is the most stable.(3) Cases in good operating condition tend to have relatively related characteristics in layouts, traffic functions, landscape elements, and space design.(4) Questionnaire interviews show that citizens are highly willing to participate in rooftop productive landscapes, while operators still experience challenges in policies, funds, and planting knowledge in practice. This paper analyses the existing problems in the development status and strategy of the rooftop productive landscape. It proposes complementary optimization strategies to serve as a reference for the rooftop design of commercial complexes and the utilization of a significant amount of idle space on the roofs.

摘要：《野草》是鲁迅遭遇启蒙信念、家族亲情、个体存在意义等多重精神危机情况下书写的诗集,它的风格形式与清醒、理性情况下书写的《呐喊》《彷徨》很不一样。其文体的杂糅、不拘格套,词语文句含混缠绕、矛盾,甚至相互否定,还有众多以"梦"为题的篇章抒写,彰显出一个病态文本的特征,而这恰恰是鲁迅潜意识里诸多矛盾、困惑的反映。鲁迅就是通过这种无意识的写作,释放了内心积郁的苦闷和焦虑,从而完成了其自我心灵的治疗。因此,《野草》是鲁迅进行自我精神分析和心灵治疗的文本,为中国现代文学开创了一条通过"潜意识的本我"进行创作的新路径。

摘要：采用吸附分离法测定了CO2驱与H2O驱采出液中原油的胶质和沥青质含量,通过析水率分析二者的乳化性,同时测定了油样的酸值、黏度、界面张力,探讨了CO2驱与H2O驱采出液中原油性质的差异。结果表明,与H2O驱原油相比,CO2驱原油中沥青质含量、胶质含量及酸值较高,黏度、界面张力较低;受上述条件的影响,CO2驱采出液中原油的乳化性较高。

摘要：气缸套是压缩机气缸的最重要的部件之一,其强度、刚度决定了压缩机的使用寿命。本文基于VS2005编程软件对Pro/E进行二次开发,设计出气缸套参数化设计系统,并导入到ANSYS Workbench中对气缸套进行了有限元模态分析。分析了气缸套的固有特性,为压缩机进一步优化设计和动态特性分析提供了理论依据。与常规设计方法相比较,参数化设计与有限元分析方法的结合提高气缸套设计效率2倍以上,具有广阔的应用前景。
