Strategic Study of CAE 2019, Volume 21, Issue 2, Pages 74-78 doi: 10.15302/J-SSCAE-2019.02.005
After nearly 30 years of exploration and practice, a “5+3” and “3+2” general practitioner (GP) training mode has been preliminarily established in China. However, China still lacks qualified GPs. In this paper, after analyzing the current situation of GP training in China, we found that the post of GP is unattractive in China; the GP training system is incomplete and lacks a process assessment mechanism; the certification and re-certification mechanisms of training bases are incomplete; and the continuous vocational development education needs to be standardized. Then, we summarize the experiences of some major countries in the world, and propose the following policy recommendations: improving the remuneration of GPs, establishing a comprehensive GP training system focusing on post competence, establishing a normalized assessment and certification mechanism for GP training bases, and setting up continuous vocational education bases for GPs.

Microwave microwave polarimeter is a sensor of measuring not only the vertical-and horizontal-polarization, but also the third and/or the forth Stokes parameters. It realizes all information about electromagnetic wave, including frequency, phase, amplitude and polarization,to be measured by a senor. The correlated information of the first two Stokes parameters is more sensitive to the anisotropy of the ocean surface. Wind direction retrieval is one of the initial motivations of the polarimeter development. In this paper, the progress and characteristic on polarimeter development are introduced and theories of ocean wind vector remote sensing are analyzed. Oceanic emission and scattering model is develoked for remote sensing wind vector using passive polarimetric microwave radiometer. The critical techniques on its system design, which include receiver and calibration methods, are discussed in order to realize scientific target of wind retrievals. Furthermore more efforts are paid on expatiating scientific topics on wind reversion methods, including geophysical model function built-up, influences of main technical specifications on retrieval precision, and wind direction ambiguity removal methods by data-processing methods and scanning geometry. The calibration errors and main specifications of polarimetric radiometer,which have significant influences on the accuracy of wind vector retrieval,are summed in detail.Finally,a new scanning geometry with fore-aft-look to remove wind direction ambiguous solution is put forward.

The life cycle integration management of the large-scale public utility construction projects refers to the process integration of every stage of the project from decisions, planning, design, implementation, operation, maintenance to the end. In this paper, in order to realize the full life-cycle target system, we studied the whole process integration management and the interrelation of different assignments in different phases. The full life-cycle process integration model of large-scale public utility construction projects was proposed. And on this basis we discussed the support conditions of full life-cycle process integration of large-scale public utility construction projects so that the project can achieve balance and harmony in the whole life cycle as well as the investment benefit and social service function can be further improved.

Strategic Study of CAE 2019, Volume 21, Issue 3, Pages 47-55 doi: 10.15302/J-SSCAE-2019.03.020
An all-climate new energy vehicle can adapt to various climatic conditions including high temperature, high humidity, and extreme cold. Currently, mature heat insulation and protective technologies have been developed to cope with high-temperature and high-humidity environments. However, at temperatures below −30 ℃, new energy vehicles are unable to start and hard to charge, and their driving range drops markedly. These problems restrict the all-climate application of new energy vehicles. In this paper, the power battery self-heating, integrated heat pump air-conditioning, and new whole-vehicle thermal insulation technologies are investigated. Integrated vehicle development and extremely cold environment tests have been conducted. The technology development trends of all-climate new energy vehicles are also analyzed. The research achievement described in this paper will be applied to the Beijing 2022 Olympic Winter Games, thus promoting the all-climate application of new energy vehicles in China and even in the world.

Hydrogen energy is crucial for building a clean, low-carbon, safe, and efficient modern energy system in China. In this article, we expound on the progress of global hydrogen energy industry and summarize the development status of China’s hydrogen energy industry from the aspects of scale, characteristics, and policies. The demand for and problems of China’s hydrogen energy industry are analyzed. Our research shows that the strategic layout of China’s hydrogen energy industry has been continuously strengthened; the investment in hydrogen energy infrastructure has been gradually increased; and a regional industrial agglomeration effect has initially emerged. However, challenges remain including defective standards systems, severe industrial homogenization, incomplete industrial chain, and limited application scenarios. To promote the high-quality development of China’s hydrogen energy industry, we suggest that China should strengthen the top-level design for hydrogen industry development, establish a technical standards system for hydrogen production, storage, and use, promote the pilot demonstration and popularization of the entire hydrogen energy industry chain, and enhance hydrogen technology innovation to achieve a high level of self-reliance.

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.

Strategic Study of CAE 2019, Volume 21, Issue 3, Pages 25-30 doi: 10.15302/J-SSCAE-2019.03.013
Marine bridge engineering in China is continuously developing to the offshore, deep-sea, long-distance, and large-scale directions. However, due to its harsh natural environment and complex geological and loading conditions, there still exist many problems in health monitoring, measurement technology, inspection technology, and maintenance-management for the lifecycle of marine bridge engineering. Therefore, after summarizing the existing problems in lifecycle management and maintenance of bridges, this paper proposes several key technologies for marine bridge development, including health monitoring based on multi-parameter, high-reliability, large-capacity, and long-distance optical-fiber sensing; space–air–ground–sea integrated measurement; automated inspection; and intelligent management and maintenance platforms. Meanwhile, this paper studies the difficulties and development directions of these technologies, and explores development strategies and recommendations for the lifecycle management and maintenance technology of marine bridge engineering, thereby providing technical support for the construction and operation safety of marine bridge engineering.

Strategic Study of CAE 2012, Volume 14, Issue 3, Pages 100-107
In this study, a durability design theory system for engineering structures' whole life-cycle design is established. The new theory system is based on the relationships between performances, cost and service life of structures in the whole life time domain. The performance index, economic index and service life index are considered as key indexes in the whole system. Based on the established system, the limit state for durability design could be determined and the features of durability limit state are also analyzed. The proposed new durability design theory system could be used in structural performance optimization in whole life period and consequently results in the promotion of environment-friendly and resource conservation.
