| 1 | Color stability of FCC gasoline显示文摘The color changes of one representative FCC gasoline were studied. The red substance in the FCC gasoline was concentrated and separated by chromatography and analyzed by elemental analysis and gas chromatography-mass spectrometry (GC-MS). The main components of the red substance were found to be aromatic amines. Complexes formed from quinones and aromatic amines are the reason why gasoline being red, and acids can destroy the complex by reaction with aromatic amines leading to decoloration of red gasoline. A mechanism for the color change of gasoline is proposed. | Song Lechun Li Peibo Lu Liang Chen Jihai Zhou Yulu Xiang Yuzhi Xia Daohong | 2012 | Petroleum Science2012，9，2： | 2 |

| 10 | SOLUTION OF MULTIPLE CRACKS IN A FINITE PLATE OF AN ELASTIC ISOTROPIC MATERIAL WITH THE DISTRIBUTED DISLOCATION METHOD显示文摘This paper presents a numerical solution to model multiple cracks in a finite plate of an elastic isotropic material. Both the boundaries and the cracks are modeled by distributed dislocations. This method results in a system of singular integral equations with Cauchy kernels which can be solved by Gauss-Chebyshev quadrature method. Four examples are provided to assess the capability of this method. | Jiong Zhang Zhan Qu Qiqing Huang Lechun Xie Cenbo Xiong | 2014 | Acta Mechanica Solida Sinica2014，27，3： | 1 |
| 11 | 表面硬化技术和硬化层深度对合金钢滚动接触疲劳性能的影响显示文摘与其他零件相比,滚动接触疲劳(RCF)是轴承、齿轮、轴中常见的一种失效模式。通常通过特殊热处理来提高这些零件的滚动接触疲劳寿命。然而热处理淬火产生的残余拉应力对零件的疲劳性能不利。此外,相对于其强度而言,全硬化零件的韧性较低。因此,表面硬化工艺被应用。通常,这些工艺的主要作用是提高表层的硬度和耐磨性。 | LECHUN XIE 王浩 王珊珊 | 2015 | 国外轴承技术2015，0，4： | 0 |
| 12 | Numerical Study for a Class of Variable Order Fractional Integral-differential Equation in Terms of Bernstein Polynomials显示文摘The aim of this paper is to seek the numerical solution of a class of variable order fractional integral-differential equation in terms of Bernstein polynomials.The fractional derivative is described in the Caputo sense.Four kinds of operational matrixes of Bernstein polynomials are introduced and are utilized to reduce the initial equation to the solution of algebraic equations after dispersing the variable.By solving the algebraic equations,the numerical solutions are acquired.The method in general is easy to implement and yields good results.Numerical examples are provided to demonstrate the validity and applicability of the method. | Jinsheng Wang Liqing Liu Yiming Chen Lechun Liu Dayan Liu | 2015 | Computer Modeling in Engineering & Sciences2015，，1： | 0 |
| 13 | 骨巨细胞瘤软组织内复发两例报道及文献复习(英文)显示文摘We investigated the clinical features of soft-tissue recurrence in giant cell tumor of bone (GCTB). Among 106 cases with GCTB in our hospital, there were 2 cases occurring soft-tissue recurrence which histories were reported. These two soft-tissue recurrences occurred with the interval of 6.9 years and 2.5 years respectively from primary diagnosis. The clinical presentation was nonspecific masses in soft tissue. Radiographic ossification was not found at periphery or within the masses. Through pathological examination peripheral ossification was found in 1 case and malignant transformation occurred in the other case. Through retrieving and reviewing literatures in PubMed, 19 cases of soft-tissue recurrence with detailed materials were collected and analyzed. Soft-tissue recurrence of GCTB is a rare episode which reflects its locally aggressive nature, the reasons of which are tumor cells implantation and tumor residual. Ossification at periphery or in the masses can be considered as a pathognomonic character of this episode in radiographic and pathohistological examination. The prevention lies in determining tumor extension preoperatively, proper non-tumor manipulations, removing the tumor and irrigating operative wound as completely as possible. | Qiang Yang Lechun Wang Zhiping Yang Xin Li Bin Meng Jianmin Li | 2009 | The Chinese-German Journal of Clinical Oncology2009，8，11： | 0 |
| 14 | Influence of Electroshocking Treatment on Microstructure and Mechanical Properties of Ti-6.5Al-3.5Mo-1.5Zr-0.3Si Thin-Wall Specimen Manufactured by Laser Melting Deposition显示文摘In order to improve the properties of titanium alloys manufactured by laser melting deposition(LMD),the electroshocking treatment(EST)was proposed in this work.The effects of EST on microstructure and mechanical properties of LMD Ti-6.5Al-3.5Mo-1.5Zr-0.3Si were investigated.The results showed that the width of the heat affected band decreased and disappeared under the thermal and athermal effects of EST,resulting in the uniform microstructure.In the microstructure,theαlaths became coarser gradually,and the quantity ofα/βinterface was reduced.The reduction of the quantity ofα/βinterface leads to make less resistant to dislocation,resulting in the reduction in hardness and strength.The discontinuous grain boundaryαphase and nucleationαcolony near grain boundary inhibited the crack propagation and improved the ductility.Summary,EST can manipulate the microstructure and improve the mechanical properties of LMD titanium alloys. | Yan Wen Xuan Sun Jian Zhou Bingliang Liu Haojie Guo Yuxin Li Fei Yin Liqiang Wang Lechun Xie Lin Hua | 2024 | Acta Metallurgica Sinica(English Letters)2024，37，1： | 0 |

| 16 | Chinese Tuina remodels the synaptic structure in neuropathic pain rats by downregulating the expression of N-methyl D-aspartate receptor subtype 2B and postsynaptic density protein-95 in the spinal cord dorsal horn显示文摘OBJECTIVE:To investigate whether the Chinese massage system,Tuina,exerts analgesic effects in a rat model of chronic constriction injury(CCI)by remodeling the synaptic structure in the spinal cord dorsal horn(SCDH).METHODS:Sixty-nine male Sprague–Dawley rats were randomly and evenly divided into the normal group,sham group,CCI group,CCI+Tuina group,CCI+MK-801[an N-methyl D-aspartate receptor subtype 2B(NR2B)antagonist]group,and CCI+MK-801+Tuina group.The neuropathic pain model was established using CCI with right sciatic nerve ligation.Tuina was administered 4 d after CCI surgery,using pressing manipulation for 10 min,once daily.Motor function was observed with the inclined plate test,and pain behaviors were observed by the Von Frey test and acetone spray test.At 19 d after surgery,the L3-L5 spinal cord segments were removed.Glutamate,interleukin 1β(IL-1β),and tumor necrosis factor-α(TNF-α)levels were detected by enzyme-linked immunosorbent assay.The protein expression levels of NR2B and postsynaptic density protein-95(PSD-95)were detected by Western blot,and the synaptic structure was observed by transmission electron microscopy(TEM).RESULTS:CCI reduced motor function and caused mechanical and cold allodynia in rats,increased glutamate concentration and TNF-αand IL-1βlevels,and increased expression of synapse-related proteins NR2B and PSD-95 in the SCDH.TEM revealed that the synaptic structure of SCDH neurons was altered.Most of these disease-induced changes were reversed by Tuina and intrathecal injection of MK-801(P<0.05 or<0.01).For the majority of experiments,no significant differences were found between the CCI+MK-801 and CCI+MK-801+Tuina groups.CONCLUSIONS:Chinese Tuina can alleviate pain by remodeling the synaptic structure,and NR2B and PSD-95 receptors in the SCDH may be among its targets. | HUANG Hongye WANG Bingqian CHEN Shuijin FANG Jiayu WANG Xiaohua CHEN Lechun JIANG Yu ZHANG Huanzhen CHEN Jincheng LIN Zhigang | 2023 | Journal of Traditional Chinese Medicine2023，43，4： | 0 |
