浅析数据技术标准与企业信息标准化建设

企业信息化的最大效益来自信息的最广泛共享、最快捷的流通和对信息进行深层次的挖掘。将分散、孤立的各类信息变成网络化的信息资源,将众多"孤岛式"的信息系统进行整合,实现信息的快捷流通和共享,是企业信息化过程中首要解决的问题。只有实现数据的标准和统一,业务流程才能通畅流转,数据标准化、规范化是实现信息集成和共享的前提,在此基础上才谈得上信息的准确、完整和及时。因此数据标准化工作是企业进行信息化建设最基础的工作,是信息化系统整体化和数据共享的基本保证。     

商业插画中视觉张力表现应该具有人文关怀和道德尺度

商业插画中视觉张力表现应该具有人文关怀和道德尺度。写作目的在于思索解决问题的方法,倡导创作符合大众审美品位的视觉作品。不要突兀、紧张和过分刺激,应该是积极向上的、从受众心理出发的、互动的视觉感受。创作具有视觉张力的商业插画要以人文关怀为出发点,提高文化内涵和道德修养。分析目前各个信息传达方,他们为推介产品不择手段。一味追求视觉注意,而忽视人文关怀和道德尺度。     

Incombustible Polymer Electrolyte Boosting Safety of Solid-State Lithium Batteries: A Review

Lithium-ion batteries with their portability, high energy density, and reusability are frequently used in today's world. Under extreme conditions, lithium-ion batteries leak, burn, and even explode. Therefore, improving the safety of lithium-ion batteries has become a focus of attention. Researchers believe using a solid electrolyte instead of a liquid one can solve the lithium battery safety issue. Due to the low price, good processability and high safety of the solid polymer electrolytes, increasing attention have been paid to them. However, polymer electrolytes can also decompose and burn under extreme conditions. Moreover, lithium dendrites are formed continuously due to the uneven charge distribution on the surface of the lithium metal anode. A short circuit caused by a lithium dendrite can cause the battery to thermal runaway. As a result, the safety of polymer solid-state batteries remains a challenge. In this review, the thermal runaway mechanism of the batteries is summarized, and the batteries abuse test standard is introduced. In addition, the recent works on the high-safety polymer electrolytes and the solution strategies of lithium anode problems in polymer batteries are reviewed. Finally, the development direction of safe polymer solid lithium batteries is prospected.

电子元器件标准的军民通用研究

针对电子元器件标准的军、民通用提出了"单元组合"和"等级划分"两种实现标准军民通用的理论方法.就电子元器件标准军民通用的几个关键问题进行了研究,认为电子元器件标准的军民通用有扩大趋势,但电子元器件标准的军民通用是有限通用,不同类型的标准可以实现军民通用化的程度明显不同,因此应采取不同策略.推动电子元器件标准军民通用必须是军方主导,且应循序渐进.含铅与否及含铅量的规定是电子元器件标准军民通用过程中需要考虑的一个重要技术问题.

Differentiation between the terms ”confined masonry“ and ”infill masonry“

This publication concerns the differentiation between the terms ”confined masonry“ and ”infill masonry“ using the example of the national technical approval Z‐17.1‐1145 – POROTON S9 MW –vertically perforated clay units with integrated thermal insulation using thin layer mortar [1].     

Proposal for the simplified design of basement walls under lateral earth pressure

This paper deals with the design of basement walls subjected to lateral earth pressure. The current simplified calculation method according to DIN EN 1996‐3/NA only covers active earth pressure, which is the lower limiting value of the earth pressure. Designing according to DIN EN 1996‐1‐1/NA, higher coefficients of earth pressure (like earth pressure at rest) can be considered, with an additional verification of the shear resistance being necessary. This paper presents a theoretical model, which forms the basis for an analytical derivation of the loadbearing capacity, and explains the required minimum values of the acting normal force to ensure sufficient resistance to cover bending and shear. Based on these results, a simplified equation is proposed for the determination of the required minimum normal force, based on the design according to DIN EN 1996‐3/NA and providing identical values in case of an earth pressure coefficient of 1/3. The required minimum load resulting from this approach fulfils the described requirement to cover bending and shear. The presented solution is verified and the conditions for application are defined. Finally, the minimum required normal forces are evaluated and tabulated for common cases relevant to building practice.
