Establishing distinctive theories and methods of design science rooted in Chinese traditional culture

Huijun ZOU, Qinghua LIANG

《机械工程前沿(英文)》 2020年 第15卷 第3期   页码 430-437 doi: 10.1007/s11465-019-0583-5

摘要: The human social development saw the formation of five unique civilizations, with the latter forming their own distinctive cultures. China’s traditional culture is its most fundamental ideological weapon for solving problems. The Chinese are good at comprehensive thinking, dialectical thinking, and systematic analysis. These ideological weapons can solve the problems of formal science and technology and create scientific and technological achievements on par with global advanced scale. Ancient China is filled with original scientific and technological achievements, which strongly prove ancient China’s possession of its own science and technology different from that of Western Renaissance. Therefore, a comprehensive understanding of science, technology, experience, and intuition is necessary. The long-held superstition regarding the West, the lack of confidence, self-denial, blind imitation of ideas, and shackles must be thrown away. Only then can we take the road toward an authentic Chinese creative design as we learn from others.

Whole-life Thinking and Engineering the Future

Roger Flanagan

《工程管理前沿(英文)》 2014年 第1卷 第3期   页码 290-296 doi: 10.15302/J-FEM-2014040

摘要: Whole-life thinking for engineers working on the built environment has become more important in a fast changing world. Whole-life thinking is not new, every project attempts to balance the initial capital cost with the operating and maintenance cost of an asset. Engineers are increasingly concerned with complex systems, in which the parts interact with each other and with the outside world in many ways — the relationships between the parts determine how the system behaves. Systems thinking provides one approach to developing a more robust whole-life approach. Systems thinking is a process of understanding how things influence one another within a wider perspective. Complexity, chaos, and risk are endemic in all major projects. New approaches are needed to produce more reliable whole-life predictions. Best value, rather than lowest cost, can be achieved by using whole-life appraisal as a part of the design and delivery strategy.

Strategic Thinking on Shallow-water Oil and Gas Exploration in Offshore China

Ke-qiang Wu,Jian-yong Xu,Bo Kang

《工程管理前沿(英文)》 2016年 第3卷 第4期   页码 349-355 doi: 10.15302/J-FEM-2016056

摘要: The oil and gas exploration in offshore China has made great achievements, and as the important areas of offshore exploration, the shallow waters contribute most of the oil and gas reserves and production. However, the available area for exploration is diminishing and the cost of exploration is rising. The field changes and ever increasing difficulties of exploration bring new challenges technically and economically. Therefore, for effective exploration of shallow-water oil and gas in offshore China, it is necessary to center on the general requirements of becoming a powerful marine country and the ideas of value exploration, initiate key research projects in the fields of China’s offshore stratigraphic-lithologic reserves, Paleogene reserves, buried-hill reserves, high temperature and pressure reserves and hydrocarbon-rich sags, and form geological theories and explorative technologies of large and medium size oil and gas field in offshore China. The measures regarding the challenges include: (1) Innovating theoretical understanding and optimizing new exploration fields, (2) developing technical capabilities and improving the success rate of exploration, and (3) enhancing management level and deepening value exploration.

A review on different theoretical models of electrocaloric effect for refrigeration

《能源前沿(英文)》 2023年 第17卷 第4期   页码 478-503 doi: 10.1007/s11708-023-0884-6

摘要: The performance parameters for characterizing the electrocaloric effect are isothermal entropy change and the adiabatic temperature change, respectively. This paper reviews the electrocaloric effect of ferroelectric materials based on different theoretical models. First, it provides four different calculation scales (the first-principle-based effective Hamiltonian, the Landau-Devonshire thermodynamic theory, phase-field simulation, and finite element analysis) to explain the basic theory of calculating the electrocaloric effect. Then, it comprehensively reviews the recent progress of these methods in regulating the electrocaloric effect and the generation mechanism of the electrocaloric effect. Finally, it summarizes and anticipates the exploration of more novel electrocaloric materials based on the framework constructed by the different computational methods.

思维的两重性及其向创造性思维的转化 纪念钱学森院士《关于思维科学》发表15周年

《中国工程科学》 2003年 第5卷 第2期   页码 26-34

摘要:

进入21世纪的新时代,带来与思维相关的两个特征:创新与共融。关于创新,如何激发创造性思维?成为热门的话题。从唯物辩证法的哲学的认识论和真理的相对性的高度来探索,发现任何一种思维形式(包括演绎法思维和定势-习惯思维)都具有两重性,即非创造性与创造性并存,在一定条件下,非创造性思维可以转化或激发为创造性思维,产生新知识,获得创新成果。关于共融,如何进行思维的界定和分类,有许多种说法。笔者把心理学与生理学的成果融合起来,形成两大类,即左半脑主导的理性思维和右半脑主导的悟性思维。其基本的思维形式的分类与思维的大类结合,成为两大类7种。把辩证法和共融结合,得到下列结论:理性思维与感性思维的统一,原有知识与新知识的统一,设想与验证的统一,发现与发明的统一,科学(真感)与艺术(美感)的统一。对最后一个结论,笔者以工业产品造型设计原理的探索为例加以说明。此原理在工业设计上属首次推出。

煤层注水参数的数量化理论正交设计优化法的研究

秦书玉,秦伟瀚

《中国工程科学》 2003年 第5卷 第10期   页码 52-55

摘要:

应用正交设计优化煤层注水工艺参数的组合,对地质条件稳定的煤层是实现最佳注水效果的一种较好的方法。但是,对于地质条件不断变化的煤层,采用该方法,其效果不一定能满足注水工程要求。为此,针对地质因素为不稳定状态下的煤层及影响煤层注水的地质因素既有定性变量又有定量变量的特征,提出利用数量化理论与正交设计2种方法确定注水工艺参数的最优组合,并进行了工程试验优化研究。试验结果表明,此法节省注水试验工程量,接近实际工程要求。

NOx removal by non-thermal plasma reduction: experimental and theoretical investigations

《化学科学与工程前沿(英文)》 2022年 第16卷 第10期   页码 1476-1484 doi: 10.1007/s11705-022-2165-z

摘要: Green and efficient NOx removal at low temperature is still desired. NOx removal via non-thermal plasma (NTP) reduction is one of such technique. This work presents the experimental and theoretical study on the NOx removal via NTP reduction (NTPRD) in dielectric barrier discharge reactor (DBD). The effect of O2 molar fraction on NOx species in the outlet of DBD, and effects of NH3/NO molar ratio and discharge power of DBD on NOx removal efficiency are investigated. Results indicate that anaerobic condition and higher discharge power is beneficial to direct removal of NOx, and the NOx removal efficiency can be up to 98.5% under the optimal operating conditions. It is also found that adding NH3 is favorable for the reduction of NOx to N2 at lower discharge power. In addition, the NOx removal mechanism and energy consumption analysis for the NTPRD process are also studied. It is found that the reduced active species ( N, N, N+, N2, NH2+, etc.) generated in the NTPRD process play important roles for the reduction of NOx to N2. Our work paves a novel pathway for NOx removal from anaerobic gas in industrial application.

《能源前沿(英文)》 2018年 第12卷 第1期   页码 87-96 doi: 10.1007/s11708-018-0513-y

摘要: Phosphorene, a two-dimensional (2D) elemental semiconductor with a high carrier mobility and intrinsic direct band gap, possesses fascinating chemical and physical properties distinctively different from other 2D materials. Its rapidly growing applications in nano-/opto-electronics and thermoelectrics call for fundamental understanding of the thermal transport properties. Considering the fact that there have been so many studies on the thermal transport in phosphorene, it is on emerging demand to have a review on the progress of previous studies and give an outlook on future work. In this mini-review, the unique thermal transport properties of phosphorene induced by the hinge-like structure are examined. There exists a huge deviation in the reported thermal conductivity of phosphorene in literature. Besides, the mechanism underlying the deviation is discussed by reviewing the effect of different functionals and cutoff distance in calculating the thermal transport properties of phosphorene. It is found that the (vdW) interactions play a key role in the formation of resonant bonding, which leads to long-ranged interactions. Taking into account of the vdW interactions and including the long-ranged interactions caused by the resonant bonding with large cutoff distance are important for getting the accurate and converged thermal conductivity of phosphorene. Moreover, a fundamental insight into the thermal transport is provided based on the review of resonant bonding in phosphorene. This mini-review summarizes the progress of the thermal transport in phosphorene and gives an outlook on future horizons, which would benefit the design of phosphorene based nano-electronics.

《能源前沿(英文)》 2016年 第10卷 第3期   页码 268-276 doi: 10.1007/s11708-016-0413-y

摘要: It is well known that the ambient temperature is a sensitive parameter which has a great effect on biology, technology, geology and even on human behavior. A prediction is a statement about an uncertain event. It is often, but not always, based upon experience or knowledge. Although guaranteed accurate information about the future is in many cases impossible, prediction can be useful to assist in making plans about possible developments. As a result, temperature profiles can be developed which accurately represent the expected ambient temperature exposure that this environment experiences during measurement. The ambient temperature over time is modeled based on the previous and data and using a Lagrange interpolation. To observe the comprehensive variation of ambient temperature the profile must be determined numerically. The model proposed in this paper can provide an acceptable way to measure the change in ambient temperature.
