| 1 | FLEXIBLE MAGNETIC WHEEL TYPE INTELLIGENT WELDING ROBOT FOR SPHERICAL TANK显示文摘An intelligent welding robot for spherical tank's all-position multi-layer welds is developed. Based on the dynamics analyzing and simulation testing, a flexible magnetic wheel mechanism is created as the robot's walking carriage. It makes the robot directly attracted to the surface of the spherical tank so as to realize the all-position walking and welding without rail. At the same time, a CCD real-time tracing system is developed for the robot to repeatedly trace the all-position and multi-layer seams. The welding tests show that the welding robot can make the all-position and multi-layer welds with high tracing accuracy, excellent quality and reliable behavior, and it can be applied for practical production. | Jiang Lipei Jiao Xiangdong Xue Long Ma Hongze Li Mingli Yang Zhaochun Department of Mechanical Engineering, Institute of Petro-chemical Technology,Beijing 102600, China | 2002 | Chinese Journal of Mechanical Engineering2002，15，2： | 9 |

| 12 | Effect of heat-treatment on the surface properties of gallium phosphide nanosolids by Raman spectroscopy显示文摘Raman spectra of gallium phosphide (GaP) nanosolids (unheated and heat-treated at 598 and 723 K, respectively) were investigated. It was observed that both the longitudinal optical mode (LO) and the transverse optical mode (TO) dis-played an asymmetry on the low-wavenumber side. The scattering bands were fitted to a sum of four Lorentzians which were assigned to the LO mode, surface phonon mode, TO mode, and a combination of Ga?O?P symmetric bending and sum band formed from the X-point TA + LA phonons, respectively. Analysis of the characteristic of surface phonon mode revealed that the surface phonon peak of the GaP nanosolids could be confirmed. In the infrared spectrum of the GaP nanoparticles, we observed the bands on account of symmetric stretching and bending of PO2, as well as stretching of Ga?O. The Raman scattering intensity arising from the Ga?O?P linkages increased as increasing the heat-treatment temperature. | ZHANG Zhaochun YUE Longyi GUO Jingkang | 2006 | Rare Metals2006，25，3： | 1 |

| 14 | Calculation of Interaction Parameters from Immiscible Phase Diagram of Alkali Metal or Alkali Earth Metal-Halide System by Means of Subregular Solution Model显示文摘In this paper, the interaction parameters in the subregular solution model, λ1 and λ2, are regarded as a linear function of temperature, T. Therefore, the molar excess Gibbs energy of A-B binary system may be reexpressed as follows: GmE= xAxB[(λ11 +λ 12T) + (λ21 + λ22T)xB] The calculation of the model parameters. λ11 ,λ12, λ21 and λ22, was carried out numerically from the phase diagrams for 11 alkali metal-alkali halide or alkali earth metal-halide systems. In addition, artificial neural network trained by known data has been used to predict the values of these model parameters. The predicted results are in good agreement with the calculated ones. The applicability of the subregular solution model to the alkali metal-alkali halide or alkali earth metal-halide systems were tested by comparing the available experimental composition along the boundary of miscibility gap with the calculated ones which were obtained by using genetic algorithm. The good agreement between the calculated and experimental results across the entire liquidus is valid evidence in support of the model. | Zhaochun ZHANG, Deliang CUI, Baibiao HUANG, Xiaoyan QIN and Minhua JIANG (Institute of Crystal Materials, Shandong University, Jinan 250100, China) | 2000 | Journal of Materials Science & Technology2000，16，3： | 1 |
| 15 | MR-seq:measuring a single cell's transcriptome repeatedly by RNA-seq显示文摘We described a novel single-cell RNA-seq technique called MR-seq(measure a single-cell transcriptome repeatedly),which permits statistically assessing the technical variation and identifying the differentially expressed genes between just two single cells by measuring each single cell twice. We demonstrated that MR-seq gave sensitivity and reproducibility similar to the standard single-cell RNA-seq and increased the positive predicate value. Application of MR-seq to early mouse embryos identified hundreds of candidate intra-embryonic heterogeneous genes among mouse 2-,4-and 8-cell stage embryos. MR-seq should be useful for detecting differentially expressed genes among a small number of cells. | Lu Yang Zhaochun Ma Chen Cao Yuhao Zhang Xinglong Wu Raymond Lee Boqiang Hu Lu Wen Hao Ge Yanyi Huang Kaiqin Lao Fuchou Tang | 2017 | Science Bulletin2017，62，6： | 1 |

| 17 | Calculation of Thermodynamic Properties from Two-liquid Coexisting Phase Diagram of Al-In System by Means of NRTL Equation显示文摘In this paper, the NRTL equation approach has been used for calculating the activity coefficientand excess Gibbs free energy of the binary alloy system involving two-liquid coexisting phases.The parameters needed for the calcutation are the differences of interaction energies (g12 - g22),(g21 - g11) and nonrandomness constant α, which are determined by solving NRTL equation withthe aid of genetic algorithm. The calculation is carried out numerically for Al-In system. Theagreement between the calculated and experimentally determined values of activity coefficientand excess Gibbs free energy is rather good, indicating the validity of the NRTL equation for thedescription of two-liquid coexisting phase alloy systems. | Zhang, Zhaochun Chen, Nianyi Peng, Ruiwu Su, Hang

| 18 | Optical and acoustic phonon modes confined in gallium phosphide nanoparticles显示文摘The main aim of this paper is to discuss the confinement effects on the optical and acoustic phonon vibrational modes in gallium phosphide(GaP) nanoparticles(cylindric grain).The Raman scattering from the GaP nanoparticles was investigated.It was found that the red-shifts of the longitudinal optical(LO) mode and transverse optical(TO) mode were 15 cm?1 and 13.8 cm?1,respectively.It is generally accepted that the red-shifts of the optical phonon modes are due to the presence of smaller nanosized particles(~1.2 nm) acting as the nanoclustered building blocks of the GaP nanoparticles.In the low frequency Raman spectrum,a set of Stokes lines with almost the same spacing was clearly observed.The scattering feature originates from the discrete phonon density of states of the nanoclustered building blocks.According to Lamb's vibrational theory,the Raman shift wavenumbers of the spheroidal mode and torsional mode of the lowest energy surface modes for the nanoclustered building blocks were calculated.Good agreement can be achieved between the calculated results and the observed scattering peaks.These results indicate that the corresponding Raman peaks are due to scattering from the localized acoustic phonons in the nanoclustered building blocks in the GaP nanoparticles. | ZHANG Zhaochun and ZHANG Neng School of Material Science and Engineering,Shanghai University,Shanghai 200072,China | 2010 | Rare Metals2010，29，6： | 0 |
| 19 | Determination of spin-orbit splitting Δ_0 of valence band at Γ for gallium phosphide nanoparticles using fluorescence and infrared spectroscopes显示文摘The value of spin-orbit splitting Δ 0 of gallium phosphide (GaP) nanoparticles was determined. The information concerning the spin-orbit splitting of the valence band at Γ was acquired using fluorescence and infrared spectroscopes. Detailed investigation on the fluorescence characteristics under ultraviolet photoexcitation reveals that two doublets of emission transitions are related to the spin-orbit splitting of the valence band. The origin of two broad violet emissions, 3.00 and 3.10 eV, can be attributed to the direct transitions near the Γ point of the Brillouin zone between the Γ 1 conduction band and Γ 15 valance band, that is, Γ 6c -Γ 8v and Γ 6c -Γ 7v , respectively. The origin of two blue emissions, 2.74 and 2.64 eV, can be attributed to the indirect transitions between the X 1 conduction band and Γ 15 valance band, that is, Δ 5c -Γ 8v and Δ 5c -Γ 7v , respectively. Based on these transitions, the spin-orbit splitting Δ 0 of the GaP nanoparticles is determined as 0.10 eV. The infrared spectrum of the GaP nanoparticles shows a band at 817 cm -1 which is assigned to the transition between the Γ 7v and Γ 8v valence band maxima. It follows therefore that the spin-orbit splitting Δ 0 is 0.10 eV. | ZHANG Zhaochun LI Jianlin | 2011 | Rare Metals2011，30，5： | 0 |
| 20 | Operational and structural aspects of a vapor-feed semi-passive direct methanol fuel cell supplied with concentrated methanol显示文摘Direct methanol fuel cell(DMFC)has great potential to replace the traditional battery in the field of portable power sources.This study investigates the operational and structural aspects of a vapor-feed semi-passive DMFC supplied with concentrated methanol.The effectiveness of using vaporous methanol to improve the cell performance is experimentally validated.Results indicate that there exits an optimal value of methanol concentration that favors both methanol supply and control of methanol crossover(MCO).With the increase in vaporization temperature,the cell performance can be enhanced.Based on the traditional structural design,a sintered porous metal plate is further used to depress the impact of MCO so that the cell performance can be significantly improved at a relatively higher methanol concentration.This is of great importance to enhance the energy density and operating duration for portable applications.The mechanisms related to the performance behaviors are discussed in detail. | Wei Yuan Yong Tang Zhaochun Zhang Bo Zhou Jun Deng | 2014 | Chinese Science Bulletin2014，59，25： | 0 |
