| 1 | 采用Ag-Cu-Zn+Ni/Mn合金钎料的碳化钨钎焊接头的界面结构和力学性能(英文)显示文摘使用管式炉在高纯氩气中730℃下,以Ag-Cu-Zn+Ni/Mn合金为钎料焊接WC-Co硬质合金。研究钎焊时间和间隙尺寸对接头的影响。结果表明,焊接15 min,间隙尺寸为150μm的样品的最大剪切强度为(156±7)MPa。采用SEM,EDS和XRD手段表征钎焊接头的的特性和结构。焊接时间从5 min延长到15 min,为液体中间层流向基材提供了较好的机会。然而,当焊接时间超过15 min时,金属相如Mn_3W_3C的形成导致了接头的剪切强度降低。 | Mahyar HASANABADI Ali SHAMSIPUR Hasan NAJAFI SANI Hamid OMIDVAR Sima SAKHAEI | 2017 | Transactions of Nonferrous Metals Society of China2017，27，12： | 6 |
| 2 | V(HSO_4)_3 catalyzed chemoselectivity acetylation of alcohols and phenols in solution and under solvent-free conditions显示文摘A variety of alcohols and phenols are efficiently acetylated with acetic anhydride in the presence of a catalytic amount of V(HSO_4)_3 in solution and under solvent free conditions.Mild reaction conditions,high yields of the products,easy procedure and selective acetylation of alcohols and phenols in the presence of amines and thiols are the main advantages of this procedure. | Farhad Shirini Ali Reza Sakhaei Masoumeh Abedini | 2009 | Chinese Chemical Letters2009，20，4： | 2 |

| 7 | Impact of pertinent parameters on foam behavior in the entrance region of porous media:mathematical modeling显示文摘Foam injection is a promising solution for control of mobility in oil and gas field exploration and development,including enhanced oil recovery,matrix-acidization treatments,contaminated-aquifer remediation and gas leakage prevention.This study presents a numerical investigation of foam behavior in a porous medium.Fractional flow method is applied to describe steady-state foam displacement in the entrance region.In this model,foam flow for the cases of excluding and including capillary pressure and for two types of gas,nitrogen(N2)and carbon dioxide(CO2)are investigated.Effects of pertinent parameters are also verified.Results indicate that the foam texture strongly governs foam flow in porous media.Required entrance region may be quite different for foam texture to accede local equilibrium,depending on the case and physical properties that are used.According to the fact that the aim of foaming of injected gas is to reduce gas mobility,results show that CO2 is a more proper injecting gas than N2.There are also some ideas presented here on improvement in foam displacement process.This study will provide an insight into future laboratory research and development of full-field foam flow in a porous medium. | Fereshteh Samimi Zahra Sakhaei Masoud Riazi | 2020 | Petroleum Science2020，17，6： | 1 |

| 10 | Interactive Kinetic Canopy with Industrial Architecture Legacy Preservation Approach显示文摘Architecture has long sought to improve both in terms of form,space and other elements.Meanwhile,the use of innovative techniques that enhance design is always one of the concerns in the field of design.Biomimetic and Nature-Friendly architecture have always inspired by natural organisms aims to emphasize harmony with the environment.From another approach,contemporary industrial architecture has a valuable place in this knowledge,and the restoration and preservation of this heritage is a serious subject.Using attractive methods like an integration of new technology and monumental heritage lead to a profound impact.To this end,designing a canopy using an interactive and kinetic pattern to value this theme can be effective on sustainable development goals in area.This canopy which is inspired by biomimetic pattern and natural potentials from the site,responses to external motivation and adapts its kinetic movements to follow human interactions.The innovative techniques are involved with choosing a precise geometrical frame and order,kinetic patterns suitable for the project and finally fabrication of an scale model from actual dimensions.By choosing a suitable site that houses building of contemporary industrial architecture such as a railway station,this paper aims at learning from nature to fulfill industrial heritage legacy retention that is in both physical and spiritual interaction with humans. | Hamidreza Sakhaei | 2020 | Journal of Architectural Research and Development2020，4，2： | 0 |
