| 3 | Characterizing center pivot irrigation with fixed spray plate sprinklers显示文摘An indoor experiment with a fixed spray plate sprinkler(FSPS) of 36-grooved plate D3000 was conducted to evaluate the discharge-pressure relationship,wetted diameter,effective width,and water application rate in this research.In addition,a field experiment with a center pivot system equipped with the same measured FSPS was carried out to investigate the radial and circular uniformity under different cycle times and settings of the percent-timer.A package of nozzles numbering from #9(1.79 mm) to #33(6.55 mm) was tested with a nozzle elevation of 1.2 m and a 20-psi pressure regulator.The results showed that the wetted diameter and average application rate increased with nozzle size,but the effective wetted width and peak instantaneous application rate had no significant relationship with nozzle size.The simulated application rate of the center pivot system using the measured water distribution data of single FSPS was in good agreement with the measured result,which verified that the improved measurement procedure and modified nozzle sizing equation of the D3000 sprayhead in this paper were correct.Reducing the percent-time cycle time from 60 s to 40 s resulted in a slight increase in the radial uniformity coefficients,with an average of 1.09% to 1.17%,while there was no significant influence on the circular uniformity coefficients. | YAN HaiJun1,JIN HongZhi2 & QIAN YiChao2 1 College of Water Conversancy and Civil Engineering,China Agricultural University,Beijing 100083,China 2 Institute of Drainage and Irrigation Machinery,Chinese Academy of Agricultural Mechanization and Sciences,Beijing 100083,China | 2010 | Science China(Technological Sciences)2010，53，5： | 11 |
| 4 | Kinetic studies of gas hydrate formation with low-dosage hydrate inhibitors显示文摘Pipeline blockage by gas hydrates is a serious problem in the petroleum industry.Low-dosage inhibitors have been developed for its cost-effective and environmentally acceptable characteristics.In a 1.072-L reactor with methane,ethane and propane gas mixture under the pressure of about 8.5 MPa at 4 °C,hydrate formation was investigated with low-dosage hydrate inhibitors PVP and GHI1,the change of the compressibility factor and gas composition in the gas phase was analyzed,the gas contents in hydrates were compared with PVP and GHI1 added,and the inhibition mechanism of GHI1 was discussed.The results show that PVP and GHI1 could effectively inhibit the growth of gas hydrates but not nucleation.Under the experimental condition with PVP added,methane and ethane occupied the small cavities of the hydrate crystal unit and the ability of ethane entering into hydrate cavities was weaker than that of methane.GHI1 could effectively inhibit molecules which could more readily form hydrates.The ether and hydroxy group of diethylene glycol monobutyl ether have the responsibility for stronger inhibition ability of GHI1 than PVP. | TANG CuiPing 1,2,DAI XingXue 1,2,DU JianWei 1,2,LI DongLiang 1,2,ZANG XiaoYa 1,2,YANG XiangYang 1 & LIANG DeQing 1 1 Guangzhou Institute of Energy Conversion,Key Laboratory of Renewable Energy and Gas Hydrate,Chinese Academy of Sciences,Guangzhou 510640,China 2 Graduate University of the Chinese Academy of Sciences,Beijing 100039,China | 2010 | Science China Chemistry2010，53，12： | 9 |
| 5 | Design,fabrication and experimental research for an electrohydrodynamic micropump显示文摘This paper presented a novel electrohydrodynamic (EHD) micropump based on MEMS technology. The working mechanisms and classification of EHD micropump were introduced. The fabrication process of EHD micropump was presented with the material selection,optimal design of microelectrode and assembly process. Static pressure experiments and flow experiments were carried out using different fluid and the channel depth. The results indicated that the micropump could achieve a maximum static pressure head of 268 Pa at an applied voltage of 90 V. The maximum flow rate of the micropump-driven fluid could reach 106 μL/min. This paper analyzed the future of combining micropump with heat pipe to deal with heat dissipation of high power electronic chips. The maximum heat dissipation capacity of 87 W/cm2 can be realized by vaporizing the micropump-driven liquid on vaporizing section of the heat pipe. | YU He, YU Jian & MA ChongFang Key Lab of Enhanced Heat Transfer & Energy Conservation, Ministry of Education and Key Lab of Heat Transfer & Energy Conversion, Beijing Municipality, College of Enviromental and Energy Engineering, Beijing University of Technology, Beijing 100124, China | 2010 | Science China(Technological Sciences)2010，53，10： | 6 |

| 11 | Gas hydrate fast nucleation from melting ice and quiescent growth along vertical heat transfer tube显示文摘During the observation of HCFC141b gas hydrate growth processes outside a ver- tical heat transfer tube, two exciting phenomena were found: fast nucleation of gas hydrate from melting ice, and the spontaneous permeation of water into the guest phases along the surface of heat transfer tube to form gas hydrate continuously. These two phenomena were explained with Zhou & Sloan’s hypothesis and the theory of surface free energy respectively, and a novel method of gas hydrate formation was presented——gas hydrate fast nucleation from melting ice and quiescent growth along heat transfer tube. There is no mechanic stirring in this method, the formed gas hydrates are compact, the ratio of unreacted interstitial water is little, which overcome the drawback of high energy cost and high ratio of unreacted interstitial water among the formed gas hydrates in the system with mechanic stirring. This finding will benefit the gas hydrate ap- plication technologies such as natural gas storage technology or cool storage technology with gas hydrate. | XIE Yingming1,2, GUO Kaihua2, LIANG Deqing2, FAN Shuanshi2, GU Jianming1 & CHEN Jinggui2 1.

| 12 | EFFECT OF MAGNETIZATION OF WATER ON INDUCTION TIME AND GROWTH PERIOD OF NATURAL GAS HYDRATE显示文摘The effect of diluted solution's magnetization on induction time and growth period of natural gas hydrate (NGH) has been investigated in quiescent reaction system at pressure of 4. 5 MPa and temperature of 274 K with SDS as surfactant, by using volume fixed and pressure falling method. Experimental results show that magnetization will have effect on the induction time of NGH. After magnetization with magnetic field intensity of 0.33 T, the induction time of NGH has been reduced to 47 min (average) from 99 min (average) in which there is no magnetization. On the other hand, the induction time has been prolonged after magnetization of the diluted solution with magnetic field intensity of 0.05 T, 0. 11 T, 0.22 T, 0.44T. Especially with magnetic field intensity of 0.11 T, the induction time had even been prolonged to 431min (average). The effect of magnetization on the growth period of NGH has not been found at the experimental condition. | KUANG Li and FAN Shuanshi(Guangzhou Institute of Energy Conversion, Chinese Academy of Sciences, Guangzhou 510070, Guangdong, China) | 2003 | 化工学报2003，54，z1： | 3 |
| 13 | Transformation Plasticity─The Effect on Metallo-Thermo-Mechanical Simulation of Carburized Quenching Process显示文摘Theory of metallo-thermo-mechamics and the developed CAE code offer a powerful tool to simulate residual stresses and distortion during heat treatment processes, in which the transformation plasticity is one of factors to be considered being coupled with stress/strain and metallic structure. It is pointed out in this paper that, especially in the case of carburized quenching, transformation plasticity plays very important role on the distortion, which is verified by axisymmetric finite element, employing heat treatment simulation code 'HEARTS'. Simulated results with the careful consideration on the effect of transformation plasticity reveal to improve remarkably the accuracy of prediction of the displacement and the mode of distortion, compensating the discrepancy between experimental and calculated results. Attention is also paid on the difference in transformation plasticity and conventional plasticity in simulating the volume fraction, stress and strain in ring-shaped specimen during quenching. Moreover some discussions are made on practical use of the effect, and recent experimental results on the coefficient of transformation plasticity are presented. | Shigeru Yamanaka, Takayuki Sakanoue, Toshikazu Yoshii, Tatsuo Inoue 1.

| 15 | Hypocrellin B doped and pH-responsive silica nanoparticles for photodynamic therapy显示文摘pH-responsive 1O2 photosensitizing systems may serve as selective photodynamic therapy(PDT) agents by targeting the acidic interstitial fluid of many kinds of tumors.In this work,a natural and clinically used photosensitizer(Hypocrellin B,HB) and a pH indicator(Bromocresol Purple,BCP) were co-encapsulated in organically modified silica nanoparticles.BCP successfully regulated the 1O2 generation efficiency of HB through the 'inner filter' effect,which shows much stronger 1O2 generation ability in an acidic than in a basic environment.In vitro experiments also demonstrated that HB-doped nanoparticles are effective in killing tumor cells by PDT. | LI ZhaoBo1,2,WANG JianGuang1,2,CHEN JingRong1,LEI WanHua1,WANG XueSong1 & ZHANG BaoWen1 1Key Laboratory of Photochemical Conversion and Optoelectronic Materials,Technical Institute of Physics and Chemistry,Chinese Academy of Sciences,Beijing 100190,China 2Graduate University of Chinese Academy of Sciences,Beijing 100049,China | 2010 | Science China Chemistry2010，53，9： | 2 |
| 16 | Molecular dynamics study of the water/n-alkane interface显示文摘Molecular dynamics simulations on the interface between liquid water and liquid n-alkane (including octane, nonane, decane, undecane and dodecane) have been performed with the purpose to study the interfacial properties: (Ⅰ) density profile; (Ⅱ) molecular orientation; (Ⅲ) interfacial tension and the temperature effect on the interfacial tension. Simulation results show that at the interface the structures of both water and n-alkane are different from those in the bulk. Water has an orientational preference due to the number of hydrogen bonds per molecule maximized. N-alkane has a more lateral orientation with respect to the interface in order to be in close contact with water. The calculated individual phase bulk density and interfacial tension of water/n-alkane systems are in good agreement with the corresponding experimental ones. | XIAO HongYan1, ZHEN Zhen1, SUN HuanQuan2, CAO XuLong2, LI ZhenQuan2, SONG XinWang2, CUI XiaoHong2 & LIU XinHou1 1Key Laboratory of Photochemical Conversion and Optoelectronic Materials, Technical Institute of Physics and Chemistry, Chinese Academy of Sciences, Beijing 100190, China 2Institute of Geological Science, Shengli Oilfield, Dongying 257001, China | 2010 | Science China Chemistry2010，53，4： | 2 |
