“干没荣利,得不以道”:入隋南人术艺化之表现、特征与缘由

隋代南人多有从事术业者,成为一个特殊群体,颇为活跃。就其术艺类别而言,阴阳、卜筮、医巫、音律、相术、技巧等皆有代表人物,在隋文帝、隋炀帝的诸多军政活动中扮演着重要角色。他们揣摩上意,奉承其旨,政治品格佞幸化,因而“待遇甚厚”,屡受封赏。在南北文化整合的历史背景下,诸人多有传输江左伎艺、融通南北之表现。这些术艺化南人多出自南朝士族,之所以“得不以道”,主要在于作为“亡国之余”,入隋南人普遍受到以关陇旧族为代表的北人的排抑,隋文帝、隋炀帝“雅信符应”,以致一些投机之南人以术艺附合,“干没荣利”。

上古时代的游吟诗人——先秦瞽艺人考

说唱艺人多为瞽人,瞽艺人起源于先秦的瞽乐官。先秦之"瞽"由"巫"而来,呈现出职业化、伎艺化和程式化的特点。他们擅长讽诵,名列"王官",是礼乐文化重要的传播者。"瞽"主要活动在宫廷之中,礼乐文化的繁荣使其"说唱"伎艺得以提高与完善。奢华的宫廷文化使得"说唱"伎艺日益由仪式趋向娱乐化。"礼坏乐崩"后,"瞽"逐渐被"优"取代而失去宫廷音乐主角的地位。上古文明的终结最终裹挟"王官"逐渐淡出朝堂,泯入民间,汇为民间的"说唱"洪流,成为以说唱谋生的瞽艺人。"瞽"可以说是上古时期的说唱艺人,他们代表我国说唱伎艺的萌芽阶段。

Effects of Tobacco Curing on Accumulation of Chemical Components and Aroma Components in Tobaccos

[Objective]The aim was to explore effects of curing technique parameters on chemical components and aromatic material accumulation to formulate a suitable curing technique and for and to achieve tobacco scalding, drying and giving aromat- ic flavor. [Method] With tobacco variety KRK 26 as test materials, the test involved parameters of three curing-techniques in down, middle and upper parts of flue-cured tobaccos in an oven to measure chemical components and aromatic substances in tobaccos. [Result] The effects of curing techniques on total sugar and reducing sug- ar differed upon temperature and humidity. The contents of chemical components, such as total alkaloid, total N and the ratio of sugar/ alkali by moderate temperature and high humidity technique were of significant differences with those by moderate temperature and moderate humidity technique and with low temperature and low hu- midity technique; the chemical components by moderate temperature and moderate humidity were of insignificant differences with the treatment by low temperature and low humidity technique. Total amount of aroma components by different curing tech- niques from high to low was the treatment by low temperature and low humidity technique （461.72 μg/g）, the treatment by moderate temperature and moderate hu- midity technique （450.06μg/g） and the treatment by moderate temperature and high humidity technique （385.12μg/g）, suggesting the content of aromatic substances is high at low temperature and low humidity. [Conclusion] Moderate temperature and high humidity curing technique has significant effects on total alkaloid, total N and the ratio of sugar/ alkali of tobaccos and different curing techniques also affect the total amount of aromatic substances of flue-cured tobaccos.

Melting purification process and refining effect of 5083 Al-Mg alloy

To improve the poor stability of casting process of Al alloy with high Mg content, which leads to poor final product quality, the melting purification process and the influences of the refiner on the microstructure and defect of 5083 alloy were studied. The results show that the optimized process for the rotary impeller degassing of 5083 alloy is as follows： a rotary speed of 250-400 r/min; a gas flow of 1.2-2.0 L/s, a refining time of 10-15 min. This optimized process can reduce the gas content in the solid alloy to 2× 10^-3 mL/g or lower. Due to the addition of grain refiner, the cast microstructure of 5083 alloy is refined. The Al-5Ti-IB wire shows the best refining effect among all the refiners. The refining effect is improved with the increase of grain refiner addition amount. And the refinement effects become stable when Ti content reaches 0.1% or higher. The surface crinkling defect of the billet can be easily found in the alloy refined with Al-5Ti-IB wire compared with the alloys refined with other refiners.

Grain refinement in AZ31 magnesium alloy rod fabricated by extrusion-shearing severe plastic deformation process

A new severe plastic deformation （SPD） method that is extrusion-shearing （ES）, which includes initial forward extrusion and shearing process subsequently, was developed to fabricate the fine grained AZ31 Mg alloys. The components of ES die were manufactured and installed to gleeble1500D thermo-mechanical simulator. Microstructure observations were carried out in different positions of ES formed rods. The results show that homogeneous microstructures with mean grain size of 2 μm are obtained at lower temperature as the accumulated true strain is 2.44. Occurring of continuous dynamic recrystallization （DRX） is the main reason for grain refinement during ES process. The experimental results show that the ES process effectively refines the grains of AZ31 magnesium. The production results of ES extrusion with industrial extruder under different extrusion conditions show that the ES extrusion can be applied in large-scale industry.

The interaction of inoculum size and original alcohol content was non-significant, that of inoculum size and p H also non-significant. On contrast, original alcohol content and p H had significant interaction.

Influence of pretreatment process on structure, morphology and electrochemical properties of Li[Ni_(1/3)Co_(1/3)Mn_(1/3)]O_2 cathode material

The layered Li[Ni1/3Mn1/3Co1/3]O2 was separately synthesized by pretreatment process of ball mill method and solution phase route, using [Ni1/3Co1/3Mn1/3]3O4 and lithium hydroxide as raw materials. The physical and electrochemical behaviors of Li[Ni1/3Mn1/3Co1/3]O2 were characterized by X-ray diffraction （XRD）, scanning electron microscopy （SEM）, field emission scanning electron microscopy （FESEM） and electrochemical charge/discharge cycling tests. The results show that the difference in pretreatment process results in the difference in compound Li[Ni1/3Co1/3Mn1/3]O2 structure, morphology and the electrochemical characteristics. The Li[Ni1/3Mn1/3Co1/3]O2 prepared by solution phase route maintains the uniform spherical morphology of the [Ni1/3Co1/3Mn1/3]3O4, and it exhibits a higher capacity retention and better rate capability than that prepared by ball mill method. The initial discharge capacity of this sample reaches 178 mA-h/g and the capacity retention after 50 cycles is 98.7% at a current density of 20 mA/g.

High temperature deformation behavior and optimization of hot compression process parameters in TC11 titanium alloy with coarse lamellar original microstructure

The high temperature deformation behaviors of α＋β type titanium alloy TC11 （Ti-6.5Al-3.5Mo-1.5Zr-0.3Si） with coarse lamellar starting microstructure were investigated based on the hot compression tests in the temperature range of 950-1100 ℃ and the strain rate range of 0.001-10 s-1. The processing maps at different strains were then constructed based on the dynamic materials model, and the hot compression process parameters and deformation mechanism were optimized and analyzed, respectively. The results show that the processing maps exhibit two domains with a high efficiency of power dissipation and a flow instability domain with a less efficiency of power dissipation. The types of domains were characterized by convergence and divergence of the efficiency of power dissipation, respectively. The convergent domain in a＋fl phase field is at the temperature of 950-990 ℃ and the strain rate of 0.001-0.01 s^-1, which correspond to a better hot compression process window of α＋β phase field. The peak of efficiency of power dissipation in α＋β phase field is at 950 ℃ and 0.001 s 1, which correspond to the best hot compression process parameters of α＋β phase field. The convergent domain in β phase field is at the temperature of 1020-1080 ℃ and the strain rate of 0.001-0.1 s^-l, which correspond to a better hot compression process window of β phase field. The peak of efficiency of power dissipation in ℃ phase field occurs at 1050 ℃ over the strain rates from 0.001 s^-1 to 0.01 s^-1, which correspond to the best hot compression process parameters of ,8 phase field. The divergence domain occurs at the strain rates above 0.5 s^-1 and in all the tested temperature range, which correspond to flow instability that is manifested as flow localization and indicated by the flow softening phenomenon in stress-- strain curves. The deformation mechanisms of the optimized hot compression process windows in a＋β and β phase fields are identified to be spheroidizing and dynamic recrystallizing controlled by self-diffusion mechanism, respectively. The microstructure observation of the deformed specimens in different domains matches very well with the optimized results.

Effect of normalizing cooling process on microstructure and precipitates in low-temperature silicon steel

Microstructure, precipitate and magnetic characteristic of fmal products with different normalizing cooling processes for Fe-3.2%Si low-temperature hot-rolled grain-oriented silicon steel were analyzed and compared with the hot-rolled plate by optical microscopy （OM）, transmission electron microscopy （TEM）, and energy dispersive spectrometry （EDS）. The results show that, the surface microstructure is uniform, the proportion of recrystallization in matrix increases, and the banding textures are narrowed; the precipitates, whose quantity in normalized plate is more than that in hot-rolled plate greatly, are mainly A1N, MnS, composite precipitates （Cu,Mn）S and so on. Normalizing technology with a temperature of 1120 ℃, holding for 3 min, and a two-stage cooling is a most advantaged method to obtain oriented silicon steel with sharper Goss texture and higher magnetic properties, owing to the uniform surface microstructures and the obvious inhomogeneity of microstructures along the thickness. The normalizing technology with the two-stage cooling is the optimum process, which can generate more fine precipitates dispersed over the matrix, and be beneficial for finished products to get higher magnetic properties.

Quantitative Description of the Effects of Sweep Efficiency and Displacement Efficiency during Chemical Flooding on a Heterogeneous Reservoir

The processes of flooding—water flooding, polymer flooding and ternary combination flooding—were simulated respectively on a 2-D positive rhythm profile geological model by using the ASP numerical modeling software developed by RIPED (Yuan, et al. 1995). The recovery coefficient, remaining oil saturation, sweep efficiency and displacement efficiency were calculated and correlated layer by layer. The results show that the sweep efficiency and displacement efficiency work different effects on different layers in the severely heterogeneous reservoir. The study shows that the displacement efficiency and sweep efficiency play different roles in different layers for severely heterogeneous reservoirs. The displacement efficiency contributes mainly to the high permeability zones, the sweep efficiency to the low permeability zones, both of which contribute to the middle permeable zones. To improve the sweep efficiency in the low permeability zones is of significance for enhancing the whole recovery of the reservoir. It is an important path for improving the effectiveness of chemical flooding in the severely heterogeneous reservoirs to inject ternary combination slug after profile control.
