The grain refinement mechanism and synergistic effect of Mn and Ti involved in the Ti-microalloying technology of thin slab casting and direct rolling （TSCR） were elucidated. Because the inevitable precipitation of TiN in high Ti-containing liquid steel decreases the volume fraction of TiN precipitated from austenite and the rapid coarse- ning rate leads to a large size of TiN particles, a relatively weak inhibition effect on the recrystallized grain growth was obtained compared with that in the low Ti-containing steel. However, the ferrite grain size in high Ti-containing steel can be refined by the so-called non-recrystallization rolling. The complex addition of Mn and Ti can improve the strength and toughness of strip remarkably, and the mechanisms are that Mn decreases the transformation tempera- ture, refines the ferrite grains, and enhances the formation of bainite and TiC precipitation in ferrite.

Extractive agents of extractive distillation separation for mixtures of dichlorobenzene were analyzed and compared, gas-liquid equilibrium data （VLE data） was measured for dichlorobenzene and diphenylamine, the appropriate extractive agent was selected by relatively volatility, the temperature was studied on the effect of extractive separation. VLE data was measured for dichlorobenzene, the parameters were simulated in Wilson equation. The infinite dilute activity coefficient of dichlorobenzene in diphenylamine were measured by chromatogram apparatus, the model parameters were correlated by the single parameter method for dichlorobenzene and diphenyl -amine, VLE data of m-dichlorobenzene-p- dichlorobenzene -o-dichlorobenzene-diphenylamine system was measured and calculated by six part model parameters. The results of correlation and experiment were provided a basis for study of extractive distillation simulation and experiment in this work.

Background The surgical treatment of intramedullary spinal cord tumor aims at complete removal and minimal postoperative deficit. This study was undertaken to evaluate the microsurgical features of intramedullary spinal cord tumors and the time for surgery and prognosis. Methods Twenty-one patients with intramedullary spinal cord tumor who had been treated at Nanfang Hospital, Guangzhou, China since 2000 were studied retrospectively. Fifteen patients were men and 6 women, aged 2-60 years （mean 29.28 years）. Thirteen patients had the tumor in the cervical segments, 4 in medulla-cervical segments, 1 in cervicothoracic segment, and 3 in thoracic spine. All the patients underwent microsurgery for the tumor through posterior approaches by laminectomy. The tumor was exposed through dorsal myelotomy, then tumor plane was removed carefully from the entire rostrocaudal area. The dura was sutured routinely. In case of tumors occupying too many spinal segments, titanium strip was applied to reconstruct the vertebral plate and keep the spinal column stable. All the patients were subjected to MR imaging early after operation. Results Complete removal of the tumor was made in 15 patients, subtotal removal in 5, and partial resection in 1. Neurological recovery was related primarily to preoperative neurological conditions of the patients. Patients with minor neurological deficit showed stable sensory and motor function or minor loss in the early postoperative period, and neurological function tended to improve with time. But those with significant or long-standing deficit could hardly demonstrate any recovery. The dissection interface between the tumor and normal cord tissue was the most important factor influencing the extent of surgical removal. Conclusions Intramedullary spinal cord tumor mostly take place in cervical segments, with glioma as the commonest type. Microsurgery is the major treatment of choice, by which tumor plane could be totally resected. Excellent micros

　　On the basis of their characteristic polar nature, phase behavior and lack of vapour pressure, ionic liquids are considered as green solvents and have attracted significant attention as an alternative reaction medium for homogeneous catalysis.[1] However, the "greenness" of typical ionic liquids used in the literature consisted of halogen-containing anions (such as [AlCl4]-, [BF4]- and [PF6]-) was limited in some sense, due to the serious environment concerns if the hydrolysis stability of the anion is poor (e.g. for [AlCl4]-and [PF6]-) or thermal stability of used ionic liquid is undesired. In both cases, the additional effort is needed to avoid the liberation of toxic and corrosive HF or HCl into the environment.……
