Chinese and German maize-based food-feed-energy systems to limited phosphate resources—a new Sino-German internationalresearch training group

《农业科学与工程前沿（英文）》 2019年第6卷第4期页码 313-320 doi: 10.15302/J-FASE-2019282

摘要：

Phosphate is supplied to agriculture by mining and fertilizer production, followed by different steps of phosphate utilization, including primary production, feed and food consumption, and conversion of biomass, with accumulation in soils, but little recycling and severe environmental losses. Phosphate is a limited essential nutrient, however, with very uneven distribution worldwide. Closing the cycle and reducing primary phosphate consumption are fundamental future challenges. Maize has a relatively high phosphate requirement. China and Germany together cover the whole range of maize production systems. The new Sino-German international research training group “Adaptation of Chinese and German maize-based food-feed-energy systems to limited phosphate resources” (AMAIZE-P) was initiated in 2018 as a joint venture of the China Agricultural University (Beijing, China) and the University of Hohenheim (Stuttgart, Germany). The interdisciplinary and complementary research is driven by the hypothesis that under phosphate limited conditions, high productivity and high phosphate use efficiency can be achieved simultaneously by adapting phosphate cycling and availability (sources) to the multipurpose phosphate demands (sinks) in maize-based food-feed-energy systems. The educational program for doctoral researchers in China and Germany includes joint block seminars, thematic field trips, case studies, methodological courses, doctoral researchers’ conferences, intercultural training sessions and personal training.

薄膜润滑径向轴承特性分析

曲庆文,柴山,姚福生

《中国工程科学》 2003年第5卷第6期页码 44-48

摘要：

薄膜润滑轴承的特性远不同于常规轴承，在考虑间隙对润滑剂产生的影响后，润滑剂的特性将发生较大的变化。由于这种变化，薄膜润滑的特性才被广泛地研究和重视。文章应用等效粘度修正模型对径向滑动轴承进行了性能分析,对无限宽轴承可得出压力计算的解析表达式,从而可精确地计算轴承的性能。

Calculated journal bearing lubrication of non-Newtonian medium with surface roughness effects

CHEN Hao-sheng, CHEN Da-rong, WANG Jia-dao, LI Yong-jian

《机械工程前沿（英文）》 2006年第1卷第3期页码 270-275 doi: 10.1007/s11465-006-0028-9

摘要： To analyze the effects of non-Newtonian lubricants and surface roughness in journal bearing lubrication, a modified Reynolds equation is derived. In the equation, differential viscosity and the first normal stress function are defined to specify the rheological properties of non- Newtonian medium. Flow factors are used to specify the effect of surface roughness. The modified Reynolds equation is numerically calculated using super over relaxation method. Numerical results of the lubrication show that the differential viscosity is the principal non-Newtonian property affecting the lubrication, it is determined by the material parameters of the lubricant and is affected by the shearing rate. Under its effect, the load capacity of non-Newtonian lubricants is not always higher or lower than that of Newtonian lubricants . The effect of the first normal stress difference increases under the conditions of dynamic loading. Surface roughness shows an obvious effect on load capacity when it is greater than one-tenth of the film thickness, and the surface with longitudinal pattern affects the load capacity most. However, surface roughness has less effect on lubrication results than lubricants non-Newtonian property.

The cavitation erosion damage process of dynamically loaded journal bearings

MA Yan-yan, CHENG Xian-hua

《机械工程前沿（英文）》 2006年第1卷第4期页码 461-464 doi: 10.1007/s11465-006-0059-2

摘要： The cavitation damage model was built using finite element analysis software MSC.Marc. This paper attempted to numerically analyze the action process based on damage mechanics when a jet created by bubble collapse acted on the bearing surface in the process of cavitation erosion. The numerical results show that the values of equivalent plastic strain and void volume fraction increase with time. The values of damage scalar are higher on the bearing surface and subsurface, and decrease when it approaches the interface of overlay and nickel layer. The strain history and damage evolvement of bearing material acted on by jet impact load can be calculated efficiently using the proposed method, which develops a new method of analyzing cavitation erosion failure of the bearing surface.

Stability and coupling dynamic behavior of nonlinear journal active electromagnetic bearing rotor system

LU Yanjun, HEI Di, WANG Yuan, DAI Rong, LU Yanjun, LIU Heng, YU Lie

《机械工程前沿（英文）》 2008年第3卷第2期页码 193-199 doi: 10.1007/s11465-008-0023-4

摘要： The stability and coupling dynamic behavior of a journal active electromagnetic bearing rotor system are analyzed. The gyroscopic effect is considered in the rotor model. The system equations are formulated by combining equations for rotor motion and decentralized proportional integral differential (PID) controllers. A method combining the predictor-corrector mechanism and the Netwon-Raphson method is presented to calculate the critical speed at the corresponding Hopf bifurcation point of the system. For periodic motions, a continuation method combining the predictor-corrector mechanism and shooting method is presented. Nonlinear unbalanced periodic motions and their stability margins are obtained using the shooting method and established continuation method for periodic motions. With the change of control parameters, the system local stability and bifurcation behaviors are obtained using the Floquet theory. The numerical examples show that the schemes not only significantly save computing cost, but also have high precision.

Being good or being known: International reputation of high-speed railway enterprises

《工程管理前沿（英文）》页码 455-466 doi: 10.1007/s42524-023-0250-8

摘要： With fierce competition in the global high-speed railway (HSR) market, international reputation has become essential for enterprises to venture into overseas markets. However, few studies have been performed on the international reputation of HSR enterprises. This study aims to reveal the formation mechanism of HSR enterprises’ international reputation by developing a theoretical framework. The researchers identified five factors and proposed a hypothetical path model based on a comprehensive literature review. After the pilot study, questionnaires were distributed to practitioners in the international HSR industry for data collection. The path model was validated based on partial least-squares structural equation modeling. Eight of the nine paths are statistically supported. Researchers have structured a theoretical framework for the international reputation of HSR enterprises from two perspectives: Being good and being known. Subsequently, a strategic framework was developed to provide targeted promotion strategies for HSR enterprises. The findings of this study contribute to existing international reputation theories using the theoretical model and provide beneficial guidance for HSR enterprises to improve their international reputation through a strategic framework.
