| 1 | Lightweight Design of Automobile Drive Shaft Based on the Characteristics of Low Amplitude Load Strengthening显示文摘There are two kinds of internationally recognized approaches in terms of lightweight design.One is based on fatigue accumulated damage theory to achieve better reliability by optimal structural design;another is to use high performance lightweight materials.The former method takes very few considerations on the structural strengthening effects caused by the massive small loads in service.In order to ensure safety,the design is usually conservative,but the strength potential of the component is not fully exerted.In the latter method,cost is the biggest obstacle to lightweight materials in automotive applications.For the purpose of light weighting design on a fuel cell vehicle,the new design method is applied on drive shafts.The method is based on the low amplitude load strengthening characteristics of the material,and allows the stress,corresponding to test load,to enter into the strengthened range of the material.Under this condition,the light weighting design should assure that the reliability of the shaft is not impaired,even maximizes the strength potential of machine part in order to achieve the weight reduction and eventually to reduce the cost.At last,the feasibility of the design is verified by means of strength analysis and modal analysis based on the CAD model of light weighted shaft.The design applies to the load case of half shaft in independent axle,also provides technological reference for the structural lightweight design of vehicles and other machineries. | ZHENG Songlin XU Honghui FENG Jinzhi ZHENG Zuanxi WANG Youtao LU Leilei | 2011 | Chinese Journal of Mechanical Engineering2011，24，6： | 16 |
| 2 | Microelement analysis of source of raw materials of terracotta warriors and horses of Qin's Mausoleum in pits No.1 and No.2显示文摘In order to search for sources of the raw material of the Qin’s terracotta warriors and horses, we selected 20 samples of pottery warriors and pottery horses of the Qin’s Mausoleum from pit No. 1,19 samples of pottery warriors and brick from pit No. 2, 20 samples of clays near the Qin’s Mausoleum and 2 samples of Yaozhou porcelain bodies. The 32 kinds of element content of each sample were measured by neutron activation analysis (NAA). These data were analyzed by fuzzy cluster analysis, the trend cluster analysis diagram was obtained. The results showed that samples of terracotta warriors and horses from pits No.1 and No. 2 were closely related to the loam layer near Qin’s Mausoleum, but their relations with the loess layers were not so close, and they were out of all relation to Yaozhou porcelain bodies. Thus, it could be deduced that the Li Mountain clay may be considered as the original place of the raw materials of the terracotta warriors and horses, the kiln sites might be located nearby the Qin’s | Weijuan Zhao Aijun Xu Rongwu Li Zhengyao Gao Guoxia Li Jianzhong Xie Guohe Han Songlin Feng Dongyu Fan Ying Zhang et al. | 2002 | Chinese Science Bulletin2002，47，16： | 6 |

| 4 | Fatigue Life Prediction under Service Load Considering Strengthening Effect of Loads below Fatigue Limit显示文摘Lightweight design requires an accurate life prediction for structures and components under service loading histories. However, predicted life with the existing methods seems too conservative in some cases, leading to a heavy structure. Because these methods are established on the basis that load cycles would only cause fatigue damage, ignore the strengthening effect of loads. Based on Palmgren-Miner Rule(PMR), this paper introduces a new method for fatigue life prediction under service loadings by taking into account the strengthening effect of loads below the fatigue limit. In this method, the service loadings are classified into three categories: damaging load, strengthening load and none-effect load, and the process for fatigue life prediction is divided into two stages: stage I and stage II, according to the best strengthening number of cycles. During stage I, fatigue damage is calculated considering both the strengthening and damaging effect of load cycles. While during stage II, only the damaging effect is considered. To validate this method, fatigue lives of automobile half shaft and torsion beam rear axle are calculated based on the new method and traditional methods, such as PMR and Modified Miner Rule(MMR), and fatigue tests of the two components are conducted under service loading histories. The tests results show that the percentage errors of the predicted life with the new method to mean life of tests for the two components are –3.78% and –1.76% separately, much lesser than that with PMR and MMR. By considering the strengthening effect of loads below the fatigue limit, the new method can significantly improve the accuracy for fatigue life prediction. Thus lightweight design can be fully realized in the design stage. | ZHAO Lihui ZHENG Songlin FENG Jinzhi | 2014 | Chinese Journal of Mechanical Engineering2014，27，6： | 4 |
| 5 | Fiber-shaped organic electrochemical transistors for biochemical detections with high sensitivity and stability显示文摘Precise and continuous monitoring of biochemicals by biosensors assists to understand physiological functions for various diagnostics and therapeutic applications.For implanted biosensors,small size and flexibility are essential for minimizing tissue damage and achieving accurate detection.However,the active surface area of sensor decreases as the sensor becomes smaller,which will increase the impedance and decrease the signal to noise ratio,resulting in a poor detection limit.Taking advantages of local amplification effect,organic electrochemical transistors(OECTs)constitute promising candidates for high-sensitive monitoring.However,their detections in deep tissues are rarely reported.Herein,we report a family of implantable,fiber-shaped all-in-one OECTs based on carbon nanotube fibers for versatile biochemical detection including H2O2,glucose,dopamine and glutamate.These fiber-shaped OECTs demonstrated high sensitivity,dynamical stability in physiological environment and antiinterference capability.After implantation in mouse brain,7-day dopamine monitoring in vivo was realized for the first time.These fiber-shaped OECTs could be great additions to the'life science'tool box and represent promising avenue for biomedical monitoring. | Xiaoying Wu Jianyou Feng Jue Deng Zhichang Cui Liyuan Wang Songlin Xie Chuanrui Chen Chengqiang Tang Zhengqi Han Hongbo Yu Xuemei Sun Huisheng Peng | 2020 | Science China Chemistry2020，63，9： | 3 |
| 6 | Neutron activation analysis and Mossbauer spectroscopy research on coloring mechanism of Chinese Ru porcelain显示文摘The characteristic spectrum and its main wavelength of Ru porcelain glaze are measured by color difference instrument to determine the relations between glaze color and its main wavelength. The content of the 30 coloring elements in Ru porcelain is determined by neutron activation analysis (NAA), which showed that iron is the major coloring element. Mossbauer spectroscopy analysis shows that the iron element in the glaze exists in the form of structural iron (Fe2+, Fe3+). The quantitative relationship between the main wavelength of glaze in various colors and the relative content of structural iron (Fe2+/Fe3+) is determined. Thus the coloring mechanism of Ru porcelain is investigated entirely. | LI Rongwu YANG Lei LI Guoxia ZHAO Weijuan GAO Zhengyao XIE Jianzhong CHEN Jin ZHANG Bin SUN Xinmin FENG Songlin JIA Xiuqin HAN Song HUANG Zhongxiang | 2002 | Chinese Science Bulletin2002，47，14： | 2 |
| 7 | Nitrate increases cisplatin chemosensitivity of oral squamous cell carcinoma via REDD1/AKT signaling pathway显示文摘Although cisplatin is one of the chemotherapeutics most frequently used in oral squamous cell carcinoma(OSCC)treatment,it exerts multiple side effects and poor chemosensitivity.Nitrate reportedly demonstrates several beneficial biological functions,and synthesized nitrates enhance the therapeutic efficacy of chemotherapy.However,the role of inorganic nitrate in cisplatin chemotherapy remains unclear.We therefore investigated the effect of inorganic nitrate exerted on cisplatin sensitivity in OSCC.We found that nitrate did not affect OSCC cell growth and apoptosis in OSCC cells and OSCC xenograft tumor animal studies.Cisplatin induced REDD1 expression and AKT activation in OSCC.However,nitrate could increase cisplatin chemosensitivity,reduce its REDD1 expression,and attenuate AKT signaling activation in OSCC cells.Dysregulation of high levels of REDD1,which could enhance AKT activation,was positively associated with poor prognosis in OSCC patients.Thus,reduced REDD1 expression and retarded AKT activation induced by inorganic nitrate might be a new potential approach to the sensitization of oral cancer to cisplatin treatment in the future. | Yuanyong Feng Xuedi Cao Bin Zhao Chunyan Song Baoxing Pang Liang Hu Chunmei Zhang Jinsong Wang Junqi He Songlin Wang | 2021 | Science China(Life Sciences)2021，64，11： | 2 |

| 14 | Design and applicability analysis of independent double acquisition circuit of all-fiber optical current transformer显示文摘The advantages of the all-fiber optical current transformer include but are not limited to being small in size,having no magnetic saturation,exhibiting high measurement accuracy,and boasting strong electromagnetic interference resistance.However,the high cost of the all-fiber optical transformer limits its promotion and application in engineering.This paper proposes a design scheme of an independent double acquisition loop for the all-fiber optical current transformer based on the single optical path.Firstly,based on the closed-loop control mode and open-loop control mode,the twochannel sampling signal demand for relay protection,and the independent dual-acquisition loop design scheme of the all-fiber optical current transformer are proposed.Secondly,the reliability and economic feasibility of the scheme are demonstrated by an analysis of system failure and cost.The results show that the scheme can actualize the acquisition function of two independent all-fiber optical current transformer products on a single all-fiber current transformer in an integrated manner,which greatly reduces the cost of the all-fiber optical current transformer in engineering applications. | Songlin Gu Liu Han Dongwei Liu Wenbin Yu Zhihong Xiao Teng Feng | 2019 | Global Energy Interconnection2019，2，6： | 1 |
