| 1 | Configuration model of partial repairable spares under batch ordering policy based on inventory state显示文摘Rational planning of spares configuration project is an effective approach to improve equipment availability as well as reduce life cycle cost(LCC). With an analysis of various impacts on support system, the spares demand rate forecast model is constructed. According to systemic analysis method, spares support effectiveness evaluation indicators system is built, and then, initial spares configuration and optimization method is researched. To the issue of discarding and consumption for incomplete repairable items, its expected backorders function is approximated by Laplace demand distribution. Combining the(s 1, s) and(R, Q) inventory policy, the spares resupply model is established under the batch ordering policy based on inventory state, and the optimization analysis flow for spares configuration is proposed. Through application on shipborne equipment spares configuration, the given scenarios are analyzed under two constraint targets:one is the support effectiveness, and the other is the spares cost. Analysis reveals that the result is consistent with practical regulation; therefore, the model's correctness, method's validity as well as optimization project's rationality are proved to a certain extent. | Ruan Minzhi Luo Yi Li Hua | 2014 | Chinese Journal of Aeronautics2014，27，3： | 21 |
| 2 | Electroacupuncture effect on neurological behavior and tyrosine kinase-JAK2 in rats with focal cerebral ischemia显示文摘OBJECTIVE:Electroacupuncture effect on neurological behavior and the expression of tyrosine kinase Janus kinase 2(JAK 2) of ischemic cortex in rats with the focal cerebral ischemia were investigated in this study.METHODS:The model of focal cerebral ischemia was established by the heat-coagulation induced the occlusion of the middle cerebral artery.The electro-acupuncture was applied on Baihui(GV 20) and Dazhui(GV 14),and AG490 was applied by intracerebroventricular infusion.The expressions of JAK2 mRNA and phospharylatedJAK2(p-JAK2) in the ischemic cortex were observed by in situ hybridization and western blotting.RESULTS:The expressions of JAK2 mRNA and p-JAK2 were rarely found in sham surgery group.In model group,the expression of JAK2 mRNA and JAK2 phosphorylation had increased.After 1 day of cerebral ischemia,the expression had reached its peak.After cerebral ischemia,the expressions of JAK2 mRNA and p-JAK2 were consistent with the neurological deficit score.Electroacupuncture treatment and AG490 intervention were able to improve the neurological deficit score after cerebral ischemia,and down-regulate the expressions of JAK2 mRNAand JAK2 phosphorylation.CONCLUSION:After cerebral ischemia,the excessive expressions of JAK2 and the JAK2 phosphorylation would be one of mechanisms by which the brain injury got worse.The therapy of electro-acupuncture could reduce the expression of JAK2,and inhibit JAK2 phosphorylated activation,so as to block the abnormal activation of signal transduction pathway which was induced by JAK2. | Rong Liu Nenggui Xu Wei Yi Kangbai Huang Minzhi Su | 2012 | Journal of Traditional Chinese Medicine2012，32，3： | 15 |

According to the method of systems analysis, the dynamic palm theorem is introduced to establish the prediction model of the spares demand rate, and its main influence factors are analyzed,based on which, the spares support effectiveness evaluation index system is studied, and the system optimization-oriented spares dynamic configuration method for multi-echelon multi-indenture system is proposed. Through the analysis of the optimization algorithm, the layered marginal algorithm is designed to improve the model calculation efficiency. In a given example, the multi-stage spares configuration project during its life cycle is gotten, the research result conforms to the actual status, and it can provide a new way for the spares dynamic optimization. | Minzhi Ruan Hua Li Jian Fu | 2017 | Journal of Systems Engineering and Electronics2017，28，5： | 7 |
| 4 | Design and synthesis of self-healing polymers显示文摘Self-healing polymers represent a class of materials with built-in capability of rehabilitating damages. The topic has attracted increasingly more attention in the past few years. The on-going research activities clearly indicate that self-healing polymeric materials turn out to be a typical multi-disciplinary area concerning polymer chemistry, organic synthesis, polymer physics, theoretical and experimental mechanics, processing, composites manufacturing, interfacial engineering, etc. The present article briefly reviews the achievements of the groups worldwide, and particularly the work carried out in our own laboratory towards strength recovery for structural applications. To ensure sufficient coverage, thermoplastics and thermosetting polymers, extrinsic and intrinsic self-healing, autonomic and non-autonomic healing approaches are included. Innovative routes that correlate materials chemistry to full capacity restoration are discussed for further development from bioinspired toward biomimetic repair. | ZHANG MingQiu RONG MinZhi | 2012 | Science China Chemistry2012，55，5： | 6 |
| 5 | Mission-oriented dynamic optimization model of carrying spares for warship redundant system显示文摘Redundancy is a common structure for warship system,and it is an effective way to improve the reliability of the system.In this paper, warship system is taken as the object of study,based on the system reliability equivalence principle, a spares demand rate calculation method for redundant system is proposed through structure transformation. According to the system analysis method, the general modeling data structure of spares support echelon and system indenture is established, and the mission success probability is taken as the optimization target to build the dynamic optimization model of carrying spares during the process of multi-phase. By introducing the Lagrange multiplier, the spares weight, volume and cost are transformed to the single target of the spares total scale, and the initial Lagrange factors and its dynamic adjustment policy is proposed. In a given example, the main influence factors of the carrying spares project are analyzed, and the study results are in accordance with the reality, which can provide a new approach to mission-oriented carrying spares optimization for the redundant system. | RUAN Minzhi LI Hua WANG Junlong | 2018 | Journal of Systems Engineering and Electronics2018，29，3： | 4 |
| 6 | Mission-Oriented Configuration Model of Aircraft Carrying Spares and Dynamic Optimization Policy显示文摘Spare parts are critical to scheduled maintenance and fault repair,and can directly affect the readiness and combat capability of equipment.Equipment′s capacity of carrying spares is influenced by its storage space and scales,so it is necessary to consider economic factors,e.g.spares cost,as well as non-economic ones,such as spares volume,mass and scale,when optimizing spares configuration.Aiming at this problem,the optimization model based on multi-constraints for carrying spares is built by METRIC theory and system analysis.Through the introduction of Lagrange factors,the spares cost is transformed to shadow price,and the optimization method for carrying spares and the dynamic adjustment policy of Lagrange factors are proposed.The result of a given example is analyzed,and demonstrates that the proposed model can be optimized with all constraints,and the research can provide a new way for carrying spares optimization. | Ruan Minzhi Wang Rui Kong Qingfu | 2016 | Transactions of Nanjing University of Aeronautics and Astronautics2016，33，5： | 3 |
| 7 | Microscopic study on stress-strain relation of granular materials显示文摘A biaxial shearing test on granular materials is numerically simulated by distinct element method (DEM). The evolution of the microstructures of granular materials during isotropic compression and shearing is investigated, on which a yield function is derived. The new yield function has a similar form as the one used in the modified Cam-clay model and explains the yield characteristics of granular materials under the isotropic compression and shear process through the change of the contact distribution N(θ) defining the contacts at particle contact angle θ. | LIU SiHong YAO YangPing SUN QiCheng LI TieJun LIU MinZhi | 2009 | Chinese Science Bulletin2009，54，23： | 2 |
| 8 | N/S co-doped 3D carbon framework prepared by a facile morphology-controlled solid-state pyrolysis method for oxygen reduction reaction in both acidic and alkaline media显示文摘Developing high-performance non-precious metal electrocatalysts for oxygen reduction reaction(ORR)is crucial for the commercialization of fuel cells and metal-air batteries.However,doped carbon-based materials only show good ORR activity in alkaline medium,and become less effective in acidic environment.We believe that an appropriate combination of both ionic and electronic transport path,and well dopant distribution of doped carbon-based materials would help to realize high ORR performance un-der both acidic and alkaline cond让ions.Accordingly,a nitrogen and sulfur co-doped carbon framework with hierarchical through-hole structure is fabricated by morphology-controlled solid-state pyrolysis of poly(aniline-co-2-ami no thiophenol)foam.The uniform high concentrations of nitrogen and sulfur,high intrinsic conductivity,and integrated three dimensional ionic and electronic transfer passageways of the 3D porous structure lead to synergistic effects in catalyzing ORR.As a result,the limiting current density of the carbonized poly(aniline-co-2-aminothiophenol)foam is equivalent to commercial Pt/C in acidic environment,and twice the latter in alkaline medium. | Juan Nong Min Zhu Kun He Aosheng Zhu Pu Xie Minzhi Rong Mingqiu Zhang | 2019 | Journal of Energy Chemistry2019，28，7： | 2 |
| 9 | Effect of Coated PHB on Properties of Abradable Seal Coating显示文摘As pore-forming materials, the coated poly-p-hydroxybenzoate(short for PHB) and h-BN can be applied in the preparation of abradable seal coatings at high temperature. The characteristics of coating such as morphology, thermal stability and composition were studied by SEM, EDS and FTIR. The results show that the modifi ed PHB will change the remained carbon amount, porosity and pore morphology of the coating, which can affect the properties of coatings. If the pore is small enough in uniform distribution, the coating with 5 MPa bond strength, 30-55 HR45Y superfi cial hardness and certain of carbon can be suitable to well abradability. | 程旭东 XIANG Hongyu YE Weiping MENG Xiaoming MIN Jie LIU Minzhi ZHANG Pu LU Wei | 2014 | Journal of Wuhan University of Technology(Materials Science)2014，29，3： | 2 |
