Strategic Study of CAE 2005, Volume 7, Issue 10, Pages 28-32
Demolishing of frame building by blast is complex and difficult. Based on mechanics process of demolishing blast of frame building, the numerical compute model on breaking of the frame building is set up in the paper. By this numerical compute way, the design projects of demolishing blasting of the frame can be simulated and the design parameters can be optimized. Through the simulation, the wastes of boreholes, explosive charges and safety protection material can be avoided. Sometimes the frame building does not collapse in the process of the demolishing blasting because the design project is not correct by experience. The situation of every member of the frame in the demolishing blasting can be computed by the present simulation way and the collapsing of the frame after blasting can be ascerlained. The numerical model offers a new design way for demolishing blast of frame building.

Given the current global energy and environmental issues resulting from the fast pace of industrialization, the discovery of new functional materials has become increasingly imperative in order to advance science and technology and address the associated challenges. The boom in metal–organic frameworks (MOFs) and MOF-derived materials in recent years has stimulated profound interest in exploring their structures and applications. The preparation, characterization, and processing of MOF materials are the basis of their full engagement in industrial implementation. With intensive research in these topics, it is time to promote the practical utilization of MOFs on an industrial scale, such as for green chemical engineering, by taking advantage of their superior functions. Many famous MOFs have already demonstrated superiority over traditional materials in solving real-world problems. This review starts with the basic concept of MOF chemistry and ends with a discussion of the industrial production and exploitation of MOFs in several fields. Its goal is to provide a general scope of application to inspire MOF researchers to convert their focus on academic research to one on practical applications. After the obstacles of cost, scale-up preparation, processability, and stability have been overcome, MOFs and MOF-based devices will gradually enter the factory, become a part of our daily lives, and help to create a future based on green production and green living.

Given the frequent occurrence of natural disasters and public emergencies, China’s land space security is facing severe challenges, especially in terms of disaster risk prevention and control as well as the planning and development of land space resilience. It is imperative to integrate resilience planning with national land space planning, to improve land space’s capacity for disaster prevention and mitigation and satisfy the country’s requirements for high-quality development of the national land. This study analyzes the current status and existing problems in the planning and construction of China’s land space resilience, proposes the objectives and general ideas, and constructs an overall framework for the planning and construction of national space resilience. A development path is also summarized from the aspects of technology methods, spatial governance, and working system. Furthermore, countermeasures are suggested from three aspects, namely, optimizing the legal and regulatory system, policy system, and technical standards system, to provide a decision-making reference for the research and practice of land space resilience planning and construction in China.

As the digital and intelligent transformation of the nuclear industry proceeds, nuclear power data is growing exponentially and has become an important asset of nuclear power plants. However, there is a lack of lifecycle data management system of nuclear power plants. This paper first summarizes the research status of nuclear power plant lifecycle data management in China, analyzes the demands for and challenges of nuclear power plant lifecycle data management, and constructs a data management framework regarding lifecycle nodes and business flows of nuclear power plants. The urgent tasks for establishing a nuclear power plant lifecycle data management system include: (1) promoting the comprehensive digitization of the nuclear power industry and unifying the nuclear power plant lifecycle data standards; (2) classifying the lifecycle data according to data types and reasonably designing the data models; and (3) scientifically formulating data quality control policies and data quality measurement standards to ensure the lifecycle data security of nuclear power plants. Furthermore, we suggest that (1) a data integration platform should be established to catalog the items, business data, and three-dimensional simulation data in the nuclear power plants to promote the interconnection of data across business systems; (2) blockchain technology should be applied to nuclear power plant lifecycle data management to ensure the authenticity and traceability of the data; (3) digital twins and model-based system engineering should be applied to the lifecycle data management of nuclear power plants to improve their intelligent development level; and (4) a green policy system should be established for nuclear power plant data management to realize the low-carbon, efficient, and sustainable development of data centers.

The China Geodetic Coordinate System 2000 (CGCS2000) has been used for several years as a formal published reference frame. The coordinates of all global navigation satellite system (GNSS) stations in China need to be corrected to align with the CGCS2000 frame. Different strategies can be adopted for the realization of an optimal reference frame. However, different strategies lead to different results, with differences as great as several decimeters when GNSS station coordinates are transformed into CGCS2000-defined coordinates. The two common methods for the coordinate correction of a GNSS station are quasi-stable adjustment under CGCS2000 and plate movement correction, and the differences between their results can be greater than 10 cm. In this study, a statistic method called “supervised clustering”is applied to the selection of GNSS reference stations; a new scheme named “artition spacing” for the grouping of all processed GNSS stations is proposed; and the plate movement correction method is used to correct the coordinates of all GNSS stations from the GNSS epoch to the CGCS2000 epoch. The results from the new partitioning method were found to be significantly better than those from the conventional station-blocking approach. When coordinates from the stations without grouping were used as the standard, the accuracy of all the three-dimensional coordinate components from the new partitioning method was better than 2 mm. The root mean squares (RMSs) of the velocities in the x, y, and z directions resulting from the supervised clustering method were 0.19, 0.45, and 0.32 mm∙a−1, respectively, which were much smaller than the values of 0.92, 0.72, and 0.97 mm∙a−1 that resulted from the conventional approach. In addition, singular spectrum analysis (SSA) was used to model and predict the position nonlinear movements. The modeling accuracies of SSA were better than 3, 2, and 5 mm in the east (E), north (N), and up (U) directions, respectively; and its prediction accuracies were better than 5 mm and 1 cm for the horizontal and vertical domains, respectively.

Developing efficient adsorbents with high uptake and selectivity for separation and recovery of C2H6 and C3H8 from natural gas is an important but challenging task. In this work, we demonstrate that high surface polarity and suitable pore diameter are two key factors that can synergistically enhance the separation performance, exemplified by metal–organic framework (MOF)-303 and Matériaux de l'Institut Lavoisier (MIL)-160, both possessing one-dimensional (1D) open channels with high density of heteroatoms and desired pore size (5–7 Å). Significantly, the uptake of MOF-303 for C3H8 is up to 3.38 mmol∙g−1 at 298 K and 5 kPa with a record-high C3H8/CH4 (5:85, v/v) ideal adsorbed solution theory (IAST) selectivity of 5114 among all reported MOFs. In addition, MOF-303 also displays high C2H6 uptake capacity (at 10 kPa) and C2H6/CH4 (10:85, v/v) selectivity, reaching 1.59 mmol∙g−1 and 26, respectively. Owing to the larger pore diameter and lower density of heteroatoms within its 1D channels, MIL-160 shows apparently lower uptake and selectivity compared to those of MOF-303, though the values exceed those of majority of reported MOFs. Density functional theory (DFT) calculations verify that the high surface polarity and the suitable pore diameter synergistically enhance the affinity of the frameworks toward C3H8 and C2H6, giving rise to the high loading capacity and selectivity for C3H8 and C2H6. Both MOFs feature remarkable moisture stability without structural change upon exposure to 95% relative humidity (RH) for a month. In addition, synthesis of both compounds can be readily scaled up through one-pot reactions to afford about 5 g samples with high crystallinity. Finally, the substantial potential of MOF-303 and MIL-160 as advanced adsorbents for efficient separation of C3H8/C2H6/CH4 has been demonstrated by ternary breakthrough experiments, regeneration tests, and cyclic evaluation. The excellent separation performance, high stability, low cost, and good scalability endow both MOFs promising adsorbents for natural gas purification and recovery of C2H6 and C3H8.

Mixed-matrix membranes (MMMs), which combine porous materials with a polymeric matrix, have gained considerable research interest in the field of gas separation due to their complementary characteristics and cooperative activation. The tailorability and diversity of porous materials grant MMMs extendable functionalities and outstanding separation performance. To achieve the full potential of MMMs, researchers have focused on the rational matching of porous fillers with polymeric matrixes to achieve enhanced compatibility at the interfaces of these materials. In this review, we highlight state-of-the-art advances in combining metal–organic frameworks (MOFs) and metal–organic cages (MOCs) with polymeric matrixes to fabricate MMMs using different strategies. We further discuss the opportunities and challenges presented by the future development of MMMs, with the aim of boosting MMM fabrication with judicious material design and selection.
