| 1 | Does diffusion tensor data reflect pathological changes in the spinal cord with chronic injury?显示文摘Magnetic resonance diffusion tensor imaging has been shown to quantitatively measure the early pathological changes in chronic cervical spondylotic myelopathy.In this study,a novel spongy polyurethane material was implanted in the rat C3–5epidural space to establish a rat model of chronic cervical spondylotic myelopathy.Diffusion tensor data were used to predict pathological changes.Results revealed that the fractional anisotropy value gradually decreased at 4,24,and 72 hours and1 week after injury in rat spinal cord,showing a time-dependent manner.Average diffusion coefficient increased at 72 hours and 1 week after implantation.Hematoxylin-eosin staining and Luxol-fast-blue staining exhibited that the number of neurons in the anterior horn of the spinal cord gray matter and the nerve fiber density of the white matter gradually reduced with prolonged compression time.Neuronal loss was most significant at 1 week after injury.Results verified that the fractional anisotropy value and average diffusion coefficient reflected the degree of pathological change in the site of compression in rat models at various time points after chronic spinal cord compression injury,which potentially has a reference value in the early diagnosis of chronic cervical spondylotic myelopathy. | Erjian Lin Houqing Long Guangsheng Li Wanlong Lei | 2013 | Neural Regeneration Research2013，8，36： | 2 |

| 8 | Numerical Simulation of Injection Molding of three-Dimensional Thin Parts显示文摘This paper is concerned with the numerical simulation of the injection mold filling process.A mathematical model based on generalized Hele-Shaw flow for an inelastic non-Newtonian fluid undernonisothermal conditions is used.A hybrid numerical scheme is employed.The numerical simulating re-sults,pressure and temperature profile,location of the melt fronts,are in a good agreement with the ex-perimental ones. | YING Daoning WANG Erjian CHENG Wenxing LU Bin | 1991 | Computer Aided Drafting,Design and Manufacturing1991，2，1： | 0 |
| 9 | AN ALGORITHM ACHIEVING VALID BOOLEAN OPERATION RESULTS ON POLYHEDRAL SOLIDS显示文摘A polyhedral solid modeler that operates on boundary representations (B-reps) of ob-jects must derive topological information from numerical data.Due to finite precision of the com-puter,unavoidable numerical calculation errors may result in ambiguous or contradictory decisionof topology.These effects cause existing polyhedral modelers to fail when confronted with objectsthat nearly align or barely intersect.Based on analysing the reasons which cause the failure of Boolean operation to fail,this paperdescribes an algorithm using solid integrity to carefully design each step of Boolean operation,sothat valid polyhedral modeling results may be achieved. | YING Daoning GU Zhengchao WANG Erjian HU Zengjia Ronghang Mold High-Tech Institute,Zhejiang University,Hangzhou 310027 P.R.China | 1992 | Computer Aided Drafting,Design and Manufacturing1992，3，1： | 0 |

| 12 | Solution properties and self-association of multi-blocks like copolymer P(AM/AA) prepared by template copolymerization显示文摘The association and properties of multi-block like copolymers(TP)of acrylamide(AM)and acrylic acid(AA)prepared by template copolymerization in aqueous solution were studied.The results showed that the copolymers of this type exhibited a significant structure effect compared with that of similar random copolymers(CP)obtained by copoly-merization in the absence of template.Decreasing the value of pH or adding Ca2+ion to the copolymer solution will make phase separation occur.The TEM images demonstrated that the phase separation caused by Ca2+ion was due to the forma-tion of extensively intermolecular cross-linking.With the increase of the pH value of copolymer solution,the changes of the solution viscosity was similar with that of homopoly-acrylic acid,which originally increased and then decreased.But the increase range of template copolymer was higher than that of homopolyacrylic acid.TEM images indicated that at the maximal viscosity the copolymer obtained in the presence of template formed coiled aggregates. | ZHANG Yuxi WU Feipeng LI Miaozhen WANG Erjian | 2007 | Frontiers of Chemical Science and Engineering2007，1，1： | 0 |
