Sheng Fang,Xiao-Bo Zuo,Hua-Neng Xu,Yue-Cheng Meng,Yan-Mei Liu 한국식품과학회 2016 Food Science and Biotechnology Vol.25 No.3

Effects of sucrose fatty acid esters (SEs) with hydrophilic-lipophilic balance (HLB) values of 5 (S-570), 9 (S-970), and 15 (S-1570) on the pasting and rheological properties of waxy rice flour (WRF) were investigated. Rapid Visco Analyzer (RVA) showed that addition of SEs affected the pasting properties of WRF. Rheological experiment includes the steady shear flow characteristics, and dynamic viscoelastic properties were also determined using a controlled-stress rheometer. The steady shear tests demonstrated that the viscosity data fitted well with the power law model (R2≥0.976) and all WRF pastes exhibited typical pseudoplastic and shear-thinning properties. Dynamic rheological measurements revealed that the addition of S-970 and S-1570 significantly increased the values of G' and G'' of samples, whereas the addition of S-570 decreased these values. The addition of S-1570 reduced the value of tanδ, whereas S-570 and S-970 increased it.

Sheng Fang 사단법인약침학회 2014 Journal of Acupuncture & Meridian Studies Vol.7 No.5

In this case report, a 48-year-old female who had suffered severe scar pain for 3 months was treated with acupuncture using the Wei Ci technique (surrounding the dragon). Scar tissue usually forms after deep trauma, such as piercings, burns, and surgery, to the dermis. In Chinese Medicine, scar tissue causes local Qi and blood stagnation which lead to pain. The Wei Ci technique (surrounding the dragon) and distal points Hegu-LI-4, Tai- chong-LIV-3, Zusanli-ST-36 were used. The patient received a total of eight treatments in 5 weeks. The scar pain decreased from 7 to 1 or 2 on a Likert scale of 0e10, with 0 being no pain and 10 being the worst pain. Acupuncture may have a good short-term pain-relieving effect on scar pain but its long- term scar-pain-relieving effects are still unclear.

Shengfang Qiao,Huqing Liang,Jia-Bao Yan,Wanying Wang 국제구조공학회 2019 Structural Engineering and Mechanics, An Int'l Jou Vol.71 No.4

Shear studs are often used to connect steel girders and concrete deck to form a composite bridge system. The application of precast concrete deck to steel-concrete composite bridges can improve the strength of decks and reduce the shrinkage and creep effect on the long-term behavior of structures. How to ensure the connection between steel girders and concrete deck directly influences the composite behavior between steel girder and precast concrete deck as well as the behavior of the structure system. Compared with traditional multi-I girder systems, a twin-I girder composite bridge system is more simplified but may lead to additional requirements on the shear studs connecting steel girders and decks due to the larger girder spacing. Up to date, only very limited quantity of researches has been conducted regarding the behavior of shear studs on twin-I girder bridge systems. One convenient way for steel composite bridge system is to cast concrete deck in place with shear studs uniformly-distributed along the span direction. For steel composite bridge system using precast concrete deck, voids are included in the precast concrete deck segments, and they are casted with cast-in-place concrete after the concrete segments are erected. In this paper, several sets of push-out tests are conducted, which are used to investigate the heavier of shear studs within the voids in the precast concrete deck. The test data are analyzed and compared with those from finite element models. A simplified shear stud model is proposed using a beam element instead of solid elements. It is used in the finite element model analyses of the twin-I girder composite bridge system to relieve the computational efforts of the shear studs. Additionally, a parametric study is developed to find the effects of void size, void spacing, and shear stud diameter and spacing. Finally, the recommendations are given for the design of precast deck using void for twin I-girder bridge systems.

Shengfang Qiao,Huqing Liang,Mengxiong Tang,Wanying Wang,Hesong Hu 국제구조공학회 2019 Structural Engineering and Mechanics, An Int'l Jou Vol.71 No.4

Seismic performance analysis of steel-brace reinforced concrete (RC) frame using topology optimization in highly seismic region was discussed in this research. Topology optimization based on truss-like material model was used, which was to minimum volume in full-stress method. Optimized bracing systems of low-rise, mid-rise and high-rise RC frames were established, and optimized bracing systems of substructure were also gained under different constraint conditions. Thereafter, different structure models based on optimized bracing systems were proposed and applied. Last, structural strength, structural stiffness, structural ductility, collapse resistant capacity, collapse probability and demolition probability were studied. Moreover, the brace buckling was discussed. The results show that bracing system of RC frame could be derived using topology optimization, and bracing system based on truss-like model could help to resolve numerical instabilities. Bracing system of topology optimization was more effective to enhance structural stiffness and strength, especially in mid-rise and high-rise frames. Moreover, bracing system of topology optimization contributes to increase collapse resistant capacity, as well as reduces collapse probability and accumulated demolition probability. However, brace buckling might weaken beneficial effects.

Shengfang Qiao,Xiaolei Han,Kemin Zhou,Weichen Li 국제구조공학회 2017 Steel and Composite Structures, An International J Vol.23 No.2

Conceptual configuration and seismic performance of high-rise steel frame-brace structure are studied. First, the topology optimization problem of minimum volume based on truss-like material model under earthquake action is presented, which is solved by full-stress method. Further, conceptual configurations of 20-storey and 40-storey steel frame-brace structure are formed. Next, the 40-storeystructure model is developed in Opensees. Two common configurations are utilized for comparison. Last, seismic performance of 40-storey structure is derived using nonlinear static analysis and nonlinear dynamic analysis. Results indicate that structural lateral stiffness and maximum roof displacement can be improved using brace. Meanwhile seismic damage can also be decreased. Moreover, frame-brace structure using topology optimization is most favorable to enhance lateral stiffness and mitigate seismic damage. Thus, topology optimization is an available way to form initial conceptual configuration in high-rise steel frame-brace structure.

Shengfang Qiao,Kemin Zhou,Jing Ji,Xiaolei Han 국제구조공학회 2016 Steel and Composite Structures, An International J Vol.21 No.3

Seismic analysis for steel frame structure with brace configuration using topology optimization based on truss-like material model is studied. The initial design domain for topology optimization is determined according to original steel frame structure and filled with truss-like members. Hence the initial truss-like continuum is established. The densities and orientation of truss-like members at any point are taken as design variables in finite element analysis. The topology optimization problem of least-weight truss-like continuum with stress constraints is solved. The orientations and densities of members in truss-like continuum are optimized and updated by fully-stressed criterion in every iteration. The optimized truss-like continuum is founded after finite element analysis is finished. The optimal bracing system is established based on optimized truss-like continuum without numerical instability. Seismic performance for steel frame structures is derived using dynamic time-history analysis. A numerical example shows the advantage for frame structures with brace configuration using topology optimization in seismic performance.

试析“多+V(一)點”與“V+多(一)點”

田生芳(Tian Shengfang) 중국어문학연구회 2014 중국어문학논집 Vol.0 No.88

This article from syntax and semantics explores the differences between how the linguistic forms “DUO+V(YI)DIAN” and “V+DUO(YI)DIAN” are employed in the sufficient language data. And we reach several conclusions: First, both “DUO+V(YI)DIAN” and “V+DUO(YI)DIAN” often use monosyllabic verbs(and a few disyllabic verbs), most of which are also autonomous verbs. However, the overall number of distinct verbs used with “V+DUO(YI)DIAN” is smaller than the number used with “DUO+V(YI)DIAN”. Additionally, the form “DUO+V(YI)DIAN” may be used in imperative sentences and with modal verbs. In terms of meaning, we can say that the form “DUO+V(YI)DIAN” typically denotes an increase in the amount of verbal activity (i.e. eating) or the amount of the patient object (i.e. food), but that the amount is not above normal. In contrast, while the form “V+DUO(YI)DIAN” also denotes an increase in eating or food, in some cases (depending on the context) this form can indicate a negative situation.
