InP shows a very high efficiency for solar light to electricity conversion in solar cell and may present an expectation property in photocatalytic hydrogen evolution.However,it suffers serious corrosion in water dispersion.In this paper,it is demonstrated that the stability and activity of the InP-based catalyst are effectively enhanced by applying an anti-corrosion SnO layer and In(OH)3 transition layer,which reduces the crystal mismatch between SnO and InP and increases charge transfer.The obtained Pt/SnO/in(OH)3/inP exhibits a hydrogen produc-tion rate of 144.42 μmol/g in 3 h under visible light illumination in multi-cycle tests without remarkable decay,123 times higher than that of naked In(OH)3/InP without any electron donor under visible irradiation.

风险管理能力是工程造价咨询企业的核心竞争力之一.企业面对诸多内部风险和外部风险,风险发生后造成的影响将最终对工程造价咨询机构造成一定程度的损害.工程造价咨询质量风险管理的目标是,找出事物运行的内在原因和规律,在遵循风险发生规律的基础上,通过事前策划和过程干预将咨询质量控制在委托方可以接受的范围之内,做到“防患于未然”.工程造价咨询同时具有技术的属性和服务的属性.文章着重从服务的视角对工程造价咨询常见质量风险进行识别,继而进行深度认知和分析,以期从更深层面思考并提出此类风险的应对之道.

Owing to the outstanding characteristics of tailorable electronic and optical properties,semiconduct-ing polymers have attracted considerable attention in recent years.Among them,organic polymer dots process large breadth of potential synthetic diversity
In recent years,defect-engineered Zr-based UiO-66 metal-organic frameworks (UiO-66(Zr) metal-organic frameworks (MOFs)) have shown huge advan-tages in catalytic,functional materials,adsorption,and other fields due to their large surface areas,well-ordered
为保证2022年北京冬奥会顺利举行,需要确保临时供电工程高质量、高效率完成.为合理确定并有效控制冬奥会临时供电工程造价,文章建立了临时供电工程单元造价模型.首先,该模型结合冬奥会临时供电工程特点精简统计出实际工程中应用比例较高的18个“单元造价”模块.其次,以单元模块为典型设计基础,按照冬奥会临时用电方案主要技术条件,结合工程供电半径实际建设情况,优化组合形成“套餐型”典型设计方案,包括基本方案模块3个和可选方案模块8个.利用“套餐型”基本方案+可选模块构成完整的设计方案,为临电工程简化了流程,提高管理时

In this paper,based on the mixture flow model,an optimized six-flux model is first established and applied to the tubular solar photocatalytic reactor.Parameters influencing photocatalyst distribution and radiation dis-tribution at the reactor outlet,viz.
TBM施工在国内已有20多年的历史,技术比较成熟,适用于15～25km中长距离、围岩状况较完整的中硬度岩石的隧洞工程,具有速度快、清洁环保、可有效降低隧洞施工对人体健康损害的优点,是未来长大深埋隧洞施工的首选工法.TBM施工及造价易受设备选型、围岩条件、渗漏水情况三方面因素的影响.设备选型可通过采购方案比选最大限度降低其对施工及造价的风险;TBM施工遭遇IV、V类围岩和渗漏水往往不可避免,而现阶段相关行业普遍对围岩类别变更、地下渗水量增加两个因素对造价影响的重视程度没有达到应有高度,招标文件相关条款约定普
