This paper presents the results of correlation analysis between the data of energetic particle pulses obtained by IMP-J spacecraft (P4: 230keV>.E>160keV) and auroral electrojet index AE. The magnetotail is devided into three regions: neutral sheet region, low latitude region and high latitude region. It is found that: (1) In the neutral sheet region, the average energetic particle fluxes is the highest among all three regions. In the high latitude region the fluxes is the lowest.

This paper presents the results of correlation analysis between the data of energetic particle pulses obtained by IMP-J spacecraft (P4: 230keV>.E>160keV) and auroral electrojet index AE. The magnetotail is devided into three regions: neutral sheet region, low latitude region and high latitude region. It is found that: (1) In the neutral sheet region, the average energetic particle fluxes is the highest among all three regions. In the high latitude region the fluxes is the lowest. This indicates that the "source" of energetic particle pulses may be located in the neatral sheet region. (2) The correlation between energetic particle pulses and AE index is most significant in the neutral sheet region, the correlation coefficient R is 0.59. In low and high latitude region, R decreases sharply. It coincide with the idea that energetic particle pulses event is substorm relevant event, the particles are accelerated by induced electric field caused by magnetic field line reconnection near the neutral sheet region. (3) Accelerated area is limited to a thin layer around neutral sheet, it coincides with Hones results.

利用行星际监察卫星IMP-J取得的高能粒子探测数据(质子能档P4:230 keV>E>160keV)与极光电激流指数AE作相关分析,在地心太阳磁层坐标下,按照Fairfield关于中性片对地心太阳磁层“赤道面”的偏离模式,把磁尾分成三个区域:中性片区域、低纬区域和高纬区域.结果表明:(1)高能粒子脉冲的平均强度在中性片区域最强,低纬次之,高纬最弱,表明高能粒子脉冲源区在中性片区域;(2)中性片附近,粒子脉冲和AE指数相关最好,达0.59,低纬次之,高纬几乎无相关,表明粒子脉冲与亚暴事件有关,它是磁尾中性片附近磁力线重联产生的感应电场加速的结果;(3)粒子加速区局限于中性片附近的薄层内,与国外结果完全一致.

During power discharges in the HL—1 Tokamak, in situ titanium coating has been used to prepare clean surface for the vacuum chamber. Titanium gettering restrains the recycllng between the impurities and the wall. The densities of the impurity gases decrease by a factor of about 3—10 in the vacuum chamber. It appears that the technique of titanium gettering is effective for controlling the plasma impurities, and improve the plasma parameters. The loop voltage V_(?) has been reduced from 3.0V to 0.4V. The average effective ion charge Z_(eff) of the plasma has been reduced to 1.4. The loss of ohmic heating power due to the radiation of an energetic neutral particle fluxes has been reduced by about 30%. The spectrum intensities of impurities—OⅤ, CⅢ, CⅣ, MoⅩⅢ, and CrⅩⅢ are reduced by about 62%, 52%, 58%, 34% and 25%, respectively. To combine with the pulse puffing gas contro lled by the program, the following results are obtained: the maximum line-averaged electron density(?) is 6.8×10~(19)m~(-3); the density and the current plateau period has been extendned to 400 ms; the confinement time of energy reaches 28 ms; the device has got into stable discharges of low q(a), i. e., q(a)=1.8; and the operation region of the device is expanded The experimental results also show that the impurity control is essential for improving the quality of the plasma in the HL—1 Tokamak.

A comprehensive,predictive two-channel model has been proposed to describe the core/annular internal recirculation flow structure in gas-solid cocurrent upflow system. The flow patternshave been determined based on minimizing the available interaction between gas and particles andthe prineiple of conservation of mass and momentum in the system.Computational results,such as those of the core region radius,voidage,gas and particlevelocities,gas and particle fluxes and their axial distributions in the core...

A comprehensive,predictive two-channel model has been proposed to describe the core/annular internal recirculation flow structure in gas-solid cocurrent upflow system. The flow patternshave been determined based on minimizing the available interaction between gas and particles andthe prineiple of conservation of mass and momentum in the system.Computational results,such as those of the core region radius,voidage,gas and particlevelocities,gas and particle fluxes and their axial distributions in the core and annular channels,arequite rational and in agreement with experimental results.The proposed model can also be used topredict the drag coefficients and backmixing in two channels,and the mass exchange between coreand annular regions.

提出了一个概念合理、预测性能好的两通道模型,描述垂直向上气固流动系统的环/核内循环流动结构。基于气固相互作用最少及质量、动量守恒原理,确定了气固两相流动状态、计算结果(如预测核心区半径、核心区及环形区内空隙率、气体速度、颗粒速度及其轴向分布等)合理,且与实验结果有良好的一致性。该模型还可以用于预测在两通道内的曳力系数,气、固返混以及两区间质量交换速率等,对反应器设计具有一定参考价值。
