| 1 | Differences in lithospheric structures between two sides of Taihang Mountain obtained from the Zhucheng-Yichuan deep seismic sounding profile显示文摘A 2-D model of lithospheric velocity structures in the southern part of the North China Craton was obtained using data from the Zhucheng-Yichuan deep seismic sounding profile.Results show that there are great differences in lithospheric structures between two sides of Taihang Mountain.In the eastern region,the lithosphere is thinner,with a thickness of about 70-80 km,while in the western region,the thickness is 85-120 km.There is a jump of the lithospheric thickness across Taihang Mountain gravity anomaly belt with a magnitude of about 30 km.P wave velocities of the lithospheric mantle and lower crust are lower in the eastern region and higher in the western region.In the eastern region,there are low velocity bodies in the middle and lower crust,while none were found in the western region.These differences indicate that the Taihang Mountain gravity anomaly belt is a belt with a abrupt change of lithospheric thickness and lithological composition.According to the Pm waveform,it can be deduced that the Moho in the eastern region is not a sharp discontinuity,but a complex transitional zone.From a preliminary analysis,it is found that the geothermal mechanical-chemical erosion could be the main mechanism causing the thinning and destruction of the lithosphere beneath the eastern side of Taihang Mountain.In addition,subduction of the Pacific Plate is an important factor which changes the properties of the lithospheric mantle of the North China Craton. | LI SongLin LAI XiaoLing LIU BaoFeng WANG ZhiSuo HE JiaYong SUN Yi | 2011 | Science China Earth Sciences2011，54，6： | 27 |
| 2 | Preparation and microstructure characterization of a nano-sized Ti^(4+)-doped AgSnO_2 electrical contact material显示文摘A Ti4+-doped nano-structured AgSnO2 material was prepared using sol-gel method and characterized by X-ray diffraction (XRD), transmis-sion electron microscopy (TEM), and scanning electron microscopy (SEM). The results show that Ti4+ cations are successfully doped into the crystal lattice of SnO2, and thus significantly improve the electrical conductivity of the sample. Furthermore, the coating of Ag on Ti4+-doped SnO2 nano-sized particles enhances the surface wettability and enables the resulting AgSnO2 material to have better mechanical properties. | ZHENG Ji LI Songlin DOU Fuqi LI Tonghui | 2009 | Rare Metals2009，28，1： | 24 |

| 4 | Additive manufacturing technology for porous metal implant applications and triple minimal surface structures: A review显示文摘Recently,the fabrication methods of orthopedic implants and devices have been greatly developed.Additive manufacturing technology allows the production of complex structures with bio-mimicry features,and has the potential to overcome the limitations of conventional fabrication methods.This review explores open-cellular structural design for porous metal implant applications,in relation to the mechanical properties,biocompatibility,and biodegradability.Several types of additive manufacturing techniques including selective laser sintering,selective laser melting,and electron beam melting,are discussed for different applications.Additive manufacturing through powder bed fusion shows great potential for the fabrication of high-quality porous metal implants.However,the powder bed fusion technique still faces two major challenges:it is high cost and timeconsuming.In addition,triply periodic minimal surface(TPMS)structures are also analyzed in this paper,targeting the design of metal implants with an enhanced biomorphic environment. | Li Yuan Songlin Ding Cuie Wen | 2019 | Bioactive Materials2019，4，1： | 24 |
| 5 | Molecular cloning,characterization and expression analysis of Sox9a and Foxl2 genes in half-smooth tongue sole(Cynoglossussemilaevis)显示文摘Two transcription factors,Sox9a and Foxl2 were cloned from half-smooth tongue sole (Cynoglossus semilaevis).Sox9a is a new duplication of C.semilaevis Sox9 gene.The complete cDNA of Sox9a gene was 1 842 bp long coding for 487 amino acids and Foxl2 gene was 1 817 bp coding for 308 amino acids.Sox9a was expressed higher in male brain,pituitary and gonad and Foxl2 were higher in female brain,pituitary and gonad.The expression of Sox9a gene in gonads of neo-males was higher than that of normal females.Sox9a and Foxl2 were expressed higher in gastrula stage than in other stages.In the period of sex differentiation,the expression of Sox9a was first going up and then going down and Foxl2 was higher expressed at 37 dph.The highest expressions of Sox9a and Foxl2 genes occurred in nine-month and 12-month old gonad tissues,respectively.Sox9a gene was considered to have inevitable links with sex reversal,sex differentiation and cell differentiation of embryos and formation of spermatogenic cells.Foxl2 was considered to play a role in sex differentiation,cell differentiation of embryos but not to be necessary for sex determination and sex reversal. | DONG Xiaoli CHEN Songlin JI Xiangshan SHAO Changwei | 2011 | Acta Oceanologica Sinica2011，30，1： | 20 |

| 7 | Single whispering-gallery mode lasing in polymer bottle microresonators via spatial pump engineering显示文摘Single-mode lasing in whispering-gallery mode(WGM)microresonators is challenging to achieve.In bottle microresonators,the highly non-degenerated WGMs are spatially well-separated along the long-axis direction and provide mode-selection capability.In this work,by engineering the pump intensity to modify the spatial gain profiles of bottle microresonators,we demonstrate a simple and general approach to realizing single-mode WGM lasing in polymer bottle microresonators.The pump intensity is engineered into an interference distribution on the bottle microresonator surface.By tuning the spacing between axial positions of the interference pump patterns,the mode intensity profiles of single-bottle WGMs can be spatially overlapped with the interference stripes,intrinsically enabling single-mode lasing and selection.Attractive advantages of the system,including high sidemode suppression factors 420 dB,large spectral tunability 48 nm,low-lasing threshold and reversible control,are presented.Our demonstrated approach may have a variety of promising applications,ranging from tunable single-mode lasing and sensing to nonlinear optics. | Fuxing Gu Fuming Xie Xing Lin Shuangyi Linghu Wei Fang Heping Zeng Limin Tong Songlin Zhuang | 2017 | Light(Science & Applications)2017，6，1： | 17 |
| 8 | 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 |
| 9 | Numerical Simulation and Experimental Study of Heat-fluid-solid Coupling of Double Flapper-nozzle Servo Valve显示文摘The double flapper-nozzle servo valve is widely used to launch and guide the equipment. Due to the large instantaneous flow rate of servo valve working under specific operating conditions, the temperature of servo valve would reach 120℃ and the valve core and valve sleeve deform in a short amount of time. So the control precision of servo valve significantly decreases and the clamping stagnation phenomenon of valve core appears. In order to solve the problem of degraded control accuracy and clamping stagnation of servo valve under large temperature difference circumstance, the numerical simulation of heat-fluid-solid coupling by using finite element method is done. The simulation result shows that zero position leakage of servo valve is basically impacted by oil temperature and change of fit clearance. The clamping stagnation is caused by warpage-deformation and fit clearance reduction of the valve core and valve sleeve. The distribution rules of the temperature and thermal-deformation of shell, valve core and valve sleeve and the pressure, velocity and temperature field of flow channel are also analyzed. Zero position leakage and electromagnet's current when valve core moves in full-stroke are tested using Electro-hydraulic Servo-valve Characteristic Test-bed of an aerospace sciences and technology corporation. The experimental results show that the change law of experimental current at different oil temperatures is roughly identical to simulation current. The current curve of the electromagnet is smooth when oil temperature is below 80℃, but the amplitude of current significantly increases and the hairy appears when oil temperature is above 80℃. The current becomes smooth again after the warped valve core and valve sleeve are reground. It indicates that clamping stagnation is caused by warpage-deformation and fit clearance reduction of valve core and valve sleeve. This paper simulates and tests the heat-fluid-solid coupling of double flapper-nozzle servo valve, and the obtained results provide the reference value for the design of double flapper-nozzle force feedback servo valve. | ZHAO Jianhua ZHOU Songlin LU Xianghui GAO Dianrong | 2015 | Chinese Journal of Mechanical Engineering2015，28，5： | 16 |
| 10 | Broadband achromatic metalens in terahertz regime显示文摘Achromatic focusing is essential for broadband operation, which has recently been realised from visible to infrared wavelengths using a metasurface. Similarly, multi-terahertz functional devices can be encoded in a desired metasurface phase profile. However, metalenses suffer from larger chromatic aberrations because of the intrinsic dispersion of each unit element. Here, we propose an achromatic metalens with C-shaped unit elements working from 0.3 to 0.8 THz with a bandwidth of approximately 91% over the centre frequency. The designed metalens possesses a high working efficiency of more than 68% at the peak and a relatively high numerical aperture of 0.385. We further demonstrate the robustness of our Cshaped metalens, considering lateral shape deformations and deviations in the etching depth. Our metalens design opens an avenue for future applications of terahertz meta-devices in spectroscopy, time-offlight tomography and hyperspectral imaging systems. | Qingqing Cheng Meilin Ma Dong Yu Zhixiong Shen Jingya Xie Juncheng Wang Nianxi Xu Hanming Guo Wei Hu Shuming Wang Tao Li Songlin Zhuang | 2019 | Science Bulletin2019，64，20： | 16 |
| 11 | Solvent de binding of water soluble binder in powder injection moulding显示文摘The solvent debinding of water soluble binder in powder injection moulding (MIM) was investigated systematically, including the effects of solvent types, temperature and the thickness of green parts on the solvent debinding rate. After studying the debinding of a green part with a thickness of 4.26 mm, it was found that, the debinding rate of polyethylene glycol(PEG) in water and alcohol was high initially, and then decreased; however, it would increase with temperature increasing. At room temperature, the dissolution rate of PEG in water was higher than that in alcohol, but the latter would be much faster with temperature increasing because the debinding activation energy in alcohol was 51.44 kJ·mol -1 ·K -1 , much higher than 24.23 kJ·mol -1 ·K -1 in water. With a green part thickness larger than 4.26 mm, the debinding was controlled by diffusion; but with that smaller than 2.36 mm, the debinding was controlled by both dissolution and diffusion. | Li Songlin(李松林) Huang Baiyun(黄伯云) Qu Xuanhui(曲选辉) Li Yimin(李益民) | 1999 | 中国有色金属学会会刊:英文版1999，9，3： | 14 |
| 12 | Fault zone structures of northern and southern portions of the main central fault generated by the 2008 Wenchuan earthquake using fault zone trapped waves显示文摘The rupture process of the May 12,2008 MS8.0 Wenchuan earthquake was very complex. To study the rupture zones generated by this earthquake,four dense temporary seismic arrays across the two surface breaking traces of the main-shock were deployed in July and recorded a great amount of aftershocks. This paper focuses on the data interpretation of two arrays across the central main fault,the northern array line 1 and southern array line 3. The fault zone trapped waves recorded by the two arrays were used to study the structure of the central main fault and the difference between the northern and southern portions. The results show that the widths of the rupture zone are about 170?200 m and 200?230 m for northern and southern portions respectively. And the corresponding dip angles are 80° and 70°. The seismic velocity inside the fracture zone is about one half of the host rock. By comparison,the northern portion of the rupture zone is slightly narrower and steeper than the southern portion. Besides these differences,one more interesting and important difference is the positions of the rupture zone with respect to surface breaking traces. At the northern portion,the rupture zone is centered at the surface breaking trace,while at the southern portion it is not but is shifted to the northwest. This difference reflects the difference of rupture behaviors between two portions of the central main fault. The width of the rupture zone is smaller than that of M8.1 Kunlun earthquake though these two earthquakes have almost the same magnitudes. Multiple ruptures may be one factor to cause the narrower rupture zone. | Songlin Li Xiaoling Lai Zhixiang Yao Qing Yang | 2009 | Earthquake Science2009，22，4： | 14 |
| 13 | Development of real-time laser-scanning system to detect tree canopy characteristics for variable-rate pesticide application显示文摘Improving pesticide application efficiency is increasingly important in orchard spraying.In this study,a laser-scanning system was designed to acquire gridding volumes of a tree to quantify the geometry characteristics of the tree canopy in real-time.A laser-scanning sensor mounted on a linear guide was utilized to measure the structure of a target tree canopy.A computer was used to receive measurement data from the laser scanner and obtain the movement distance of the laser-scanning sensor from a controller.An algorithm written with VC#program was designed to calculate gridding volumes of trees by recognizing valid measurement data from the laser scanner.Laboratory evaluations were conducted on three kinds of regular objects,and the maximum relative errors of section volumes of the cuboid,triangular prism and cylinder objects were 3.3%,7.9%and 9.4%,respectively,which illustrated that the algorithm could calculate the section volumes in different parts of the objects with high accuracy.A conifer tree and an apple tree were chosen to verify detecting accuracy of the laser-scanning system at variable speeds and grid sizes.The variation coefficients of total volumes for each kind of the tree were 0.078 and 0.041,respectively,which indicated that the laser-scanning system could be applied to provide the gridding volumes of different canopy densities in real-time with good reliability for guiding a variable-rate sprayer. | Cai Jichen Wang Xiu Song Jian Wang Songlin Yang Shuo Zhao Chunjiang | 2017 | International Journal of Agricultural and Biological Engineering2017，10，6： | 14 |
| 14 | Research and Practice of Blending Teaching Based on “MOOC + SPOC + Flipped Classroom” for Software Engineering显示文摘Based on 'MOOC + SPOC + Flipped Classroom', a particular blending teaching pattern adapting to MOOC teaching is proposed to strengthen software engineering students' abilities to study themselves and practice innovatively. Firstly, the process of MOOC development in China is introduced. The distinguishing feature and effect of MOOC teaching are analyzed, followed by the comparison with traditional class. The online Plus offline blending teaching pattern is the combination of online self-study on MOOC before class, seminar study of flipped classroom in class and the summary after class. With the demonstration of a typical case, a progressive strategy is given to implement blending teaching. Finally, the blending teaching pattern is assessed from multiple perspectives, of which both advantages and disadvantages are dissected. Through primary exploration, introducing online study and flipped classroom, blending teaching plays a positive role in software engineering teaching, which means traditional teaching pattern is changed. Meanwhile, students' innovative consciousness and practical ability are inspired. Nevertheless, new problems arise, so that intensive practice and improvement are necessary. | Ce Zhang Dianhui Chu Songlin Gu Xiaofei Xu Jianan Jiang Zheng Wang Hua Zhang | 2018 | 计算机教育2018，，12： | 14 |
| 15 | Estimates of genetic and phenotypic parameters for weight and length in Paralichthys olivaceus(Temminck et Schlegel)显示文摘The complete diallel cross design was employed to estimate the genetic parameters of the growth of Japanese flounder (Paralichthys olivaceus). A total of 60 full-sib families were cultivated and two growth-related traits, body weight (BW) and body length (BL), were examined at average 2, 3 and 8 months of age respectively, with 1 800 individuals measured in each age group (30 per family). Based on the additive-dominance-maternal-effect genetic analysis model, the restricted maximum likelihood approach was used to estimate various (co)variance components. The results showed that narrow-sense heritability estimates of BW and BL were respectively: 0.29 ± 0.01 and 0.22 ± 0.02 at 2 months of age, 0.32 ± 0.02 and 0.30 ± 0.04 at 3 months of age, 0.48 ± 0.04 and 0.40 ± 0.05 at 8 months of age; broad-sense heritability estimates were respectively: 0.44 ± 0.02 and 0.54 ± 0.04 at 2 months of age, 0.35 ± 0.01 and 0.36 ± 0.03 at 3 months of age, 0.49 ± 0.03 and 0.45 ± 0.04. All heritabilities were statistically significant (P <0.05). Additive genetic correlations between BW and BL at 2, 3 and 8 months of age were consistently positive and highly significant (P <0.01): 0.93 ± 0.02, 0.95 ± 0.03 and 0.92 ± 0.03 respectively. Maternal effect was significant (P <0.05) only at 2 months of age, and was not detected at 3 and 8 months of age. According to the heritability estimates, the mass selection strategy should be efficient for the breeding of Japanese flounder. | TIAN Yongsheng XU Tianjun LIANG You CHEN Songlin | 2011 | Acta Oceanologica Sinica2011，30，6： | 13 |

| 17 | Non-coding RNAs as Emerging Regulators of Neural Injury Responses and Regeneration显示文摘Non-coding RNAs(ncRNAs) are a large cluster of RNAs that do not encode proteins,but have multiple functions in diverse cellular processes.Mounting evidence indicates the involvement of nc RNAs in the physiology and pathophysiology of the central and peripheral nervous systems.It has been shown that numerous ncRNAs,especially micro RNAs and long non-coding RNAs,are differentially expressed after insults such as acquired brain injury,spinal cord injury,and peripheral nerve injury.These ncRNAs affect neuronal survival,neurite regrowth,and glial phenotype primarily by targeting specific mRNAs,resulting in translation repression or degradation of the mRNAs.An increasing number of studies have investigated the regulatory roles of micro RNAs and long non-coding RNAs in neural injury and regeneration,and thus a new research field is emerging.In this review,we highlight current progress in the field in an attempt to provide further insight into post-transcriptional changes occurring after neural injury,and to facilitate the potential use of ncRNAs for improving neural regeneration.We also suggest potential directions for future studies. | Songlin Zhou Fei Ding Xiaosong Gu | 2016 | Neuroscience Bulletin2016，32，3： | 12 |
| 18 | Anlotinib has good efficacy and low toxicity: a phase Ⅱ study of anlotinib in pre-treated HER-2 negative metastatic breast cancer显示文摘Objective:Anlotinib is a novel tyrosine kinase inhibitor blocking angiogenesis.This study was performed to assess the efficacy and safety of anlotinib in patients with metastatic breast cancer.Methods:Patients with HER2-negative breast cancer,who were pre-treated with anthracycline or taxanes in a neoadjuvant,adjuvant,or metastatic setting,and had treatment failure after at least one prior chemotherapy regimen in the metastatic setting were enrolled.Anlotinib was administered at 12 mg daily for 14 days in a 21-day cycle until disease progression or unacceptable toxicity occurred.Simultaneously,5–10 m L of venous blood was collected to perform circulating tumor DNA(ct DNA)testing every 2 treatment cycles.The primary endpoint was the objective response rate(ORR).Secondary endpoints included the disease control rate(DCR),progression-free survival(PFS),overall survival,safety,and biomarkers.Results:Twenty-six eligible patients were enrolled,with a median age of 56(30–75)years.The median follow-up time was 10.5 months.The ORR was 15.4%,the DCR was 80.8%,and the median PFS was 5.22 months(95%confidence interval 2.86–6.24).Fourteen(53.8%)patients survived for more than 10 months.The changes in the detectable ct DNA variant allele frequency were consistent with the tumor response.The most common treatment-related adverse events were hypertension(57.7%),thyroidstimulating hormone elevation(34.6%),and hand-foot syndrome(23.1%).Conclusion:Anlotinib showed objective efficacy with tolerable toxicity in heavily pre-treated,metastatic HER2-negative breast cancer.The dynamic changes in the ct DNA variant allele fraction may be predictive of the tumor response. | Nanlin Hu Yiran Si Jian Yue Tingting Sun Xue Wang Zhuqing Jia Songlin Gao Qiao Li Yang Shao Jiayu Wang Yang Luo Fei Ma Binghe Xu Peng Yuan | 2021 | Cancer Biology & Medicine2021，18，3： | 11 |

| 20 | Microstructure, porosity and mechanical properties of selective laser melted AlSi10Mg显示文摘Finite element modeling(FEM),microscopy,X-ray computed tomography(CT)and mechanical property tests were used to study the microstructure,porosity and mechanical properties of an AlSi10Mg alloy produced by selective laser melting(SLM).The simulation of the melt pool and thermal history under different energy densities produced an optimized result with an energy density of 44.5 J·mm-3.The high cooling rate during the SLM process significantly refined the previous a-Al dendrites.The growth direction of the network-like Al-Si eutectic structure at different orientations confirmed the anisotropic nature of the microstructure.Furthermore,the microhardness,tensile testing and fracture analysis results proved that there were no obvious distinctions in the strength between the transverse and longitudinal directions,and that the ductility was anisotropic,possibly due to the shape and distribution of the pores.The pores measured by X-ray CT at different energy densities confirmed that the sphericity of the pores was inversely related to pores volumes.With optimized processing conditions,the porosity of the selective laser melted sample decreased leading to the improved fabricated fuel system component via SLM. | Jing CHEN Wei HOU Xiuzhuan WANG Songlin CHU Zhiyi YANG | 2020 | Chinese Journal of Aeronautics2020，33，7： | 9 |
