保价运输是承运人限额责任制度的组成内容,是激励承托双方进行安全投资的有效机制。保险是建立在大数定律基础上的风险分散与损失补偿制度,是独立于运输生产的风险管理工具。保价运输与保险在本质上都是运输风险管理工具,有协同发展的科学基础。在分析保价运输属性的基础上,指出保价保险协同发展的必要性,提出保价保险协同模式建议。从运输风险分配入手,调整承运人责任分配范围并提升保价保障水平,开发与保价互为补充的货运保险附加总括保险,建立稳定有效的运输风险分配结构,是保价与保险协同发展的可选模式,可以优化保价管理制度,助力全程物流运输安全,提升铁路服务质量,服务经济社会发展。

An Energy-Efficient Electrochemical Method for CuO-TiO_2 Nanotube Array Preparation with Visible-Light Responses

Acta Metallurgica Sinica(English Letters) 2014年第1期27卷 149-155页

A rapid and energy-efficient method was presented for preparing CuO-TiO2 nanotube arrays. TiO2 nanotube arrays were first prepared by anodic oxidation using titanium anode and platinum cathode. Then, the formed TiO2 nanotube arrays and Pt were used as cathode and anode, respectively, for subsequent formation of CuO-TiO2 nanotube arrays, through an electro- chemical process in a solution of 0.1 mol/L CuSO4. The morphology and composition of the CuO-TiO2 nanotube arrays were characterized using field-emission scanning electron microscopy, X-ray photoelectron spectroscopy （XPS）, X-ray diffraction （XRD）, and UV-Vis diffusion reflection spectroscopy （UV-Vis DRS）. XPS and XRD analyses suggested that the Cu element in the nanotubes existed in CuO form, and its content changed along with the voltage during the second electrochemical process. The photocatalytic activities of the CuO-TiO2 nanotube arrays were evaluated by the degradation of a model dye, rhodamine B. The results showed that Cu incorporation aroused wide visible-light adsorption and improved the photocatalytic efficiency of TiO2 nanotube arrays significantly under visible-light irradiation. The stability of the CuO-TiO2 nanotube arrays was also detected.

In this paper,we describe and analyze two datasets entitled“Homogenised monthly and daily temperature and precipitation time series in China during 1960–2021”and“Homogenised monthly and daily temperature and precipitation time series in Greece during 1960–2010”.These datasets provide the homogenised monthly and daily mean(TG),minimum(TN),and maximum(TX)temperature and precipitation(RR)records since 1960 at 366 stations in China and 56stations in *** datasets are available at the Science Data Bank repository and can be downloaded from https://***/10.57760/sciencedb.01731 and https://***/10.57760/*** China,the regional mean annual TG,TX,TN,and RR series during 1960–2021 showed significant warming or increasing trends of 0.27℃(10 yr)^(-1),0.22℃(10 yr)^(-1),0.35℃(10 yr)^(-1),and 6.81 mm(10 yr)-1,*** of the seasonal series revealed trends significant at the 0.05level,except for the spring,summer,and autumn RR *** Greece,there were increasing trends of 0.09℃(10 yr)-1,0.08℃(10 yr)^(-1),and 0.11℃(10 yr)^(-1)for the annual TG,TX,and TN series,respectively,while a decreasing trend of–23.35 mm(10 yr)^(-1)was present for *** seasonal trends showed a significant warming rate for summer,but no significant changes were noted for spring(except for TN),autumn,and *** RR,only the winter time series displayed a statistically significant and robust trend[–15.82 mm(10 yr)^(-1)].The final homogenised temperature and precipitation time series for both China and Greece provide a better representation of the large-scale pattern of climate change over the past decades and provide a quality information source for climatological analyses.
