| 1 | Characteristics of gas-solid micro fluidized beds for thermochemical reaction analysis显示文摘Fuel conversion and clean energy reaction systems involve a variety of catalytic and non-catalytic gas-solid thermochemical reactions.A good understanding of the correct reaction mechanism and kinetics,as well as the profiles of reaction products,is of great significance to the development,design,and operation of such reaction systems.The micro fluidized bed reaction analysis provides an efficient and reliable method to acquire this essential information with low capital and operating costs,low energy consumption and enhanced safety.This paper provides an overview of the system and its characteristics for the micro fluidized bed reaction analyzer that has been well proven to be a reliable new approach as well as an instrument for characterizing various gas-solid thermochemical reactions. | Zhennan Han Junrong Yue Xi Zeng Jian Yu Fang Wang Shaozeng Sun Hong Yao Guangqian Luo Xuejing Liu Yining Sun Fu Ding Liangliang Fu Lei Shi Kangjun Wang Jiebin Yang Shaonan Wang Xueqing Chen Dingrong Bai Guangwen Xu | 2020 | Carbon Resources Conversion2020，3，1： | 6 |
| 2 | Experimental investigation on flow asymmetry in solid entrance region of a square circulating fluidized bed显示文摘To study the influence of back feeding particles on gas-solid flow in the riser, this paper investigated the flow asymmetry in the solid entrance region of a fluidized bed by particle concentration/velocity measurements in a cold square circulating fluidized beds (CFB). The pressure drop distribution along the riser and the saturation carrying capacity of gas for Geldart-B type particles were first analyzed. Under the condition of u0=4 m/s and Gs=21 kg/(m2 s), the back feeding particles were found to penetrate the lean gas-solid flow near the entrance (rear) wall before reaching the opposite (front) wall, thus leading to a relatively denser region near the front wall in the bottom bed. Higher solid circulation rate (u0=4 m/s, Gs=33 kg/(m2 s)) resulted in a higher particle concentration in the riser. However the back feeding particles with higher momentum increased the asymmetry of the particle concentration/velocity profile in the solid entrance region. Lower air velocity (u0=3.2 m/s) and Gs=21 kg/(m2 s), beyond the saturation carrying capacity of gas, induced an S-shaped axial solid distribution with a denser bottom zone. This limited the penetration of the back feeding particles and forced the fluidizing air to flow in the central region, thus leading to a higher solid holdup near the rear wall. Under the conditions of u0=4 m/s and Gs=21 kg/(m2 s), addition of coarse particles (dp=1145 m) into the bed made the radial distribution of solids more symmetrical. | Zhengyang Wang Shaozeng Sun Hao Chen Qigang Deng Guangbo Zhao Shaohua Wu | 2009 | Particuology2009，7，6： | 4 |
| 3 | Conceptual Metaphor and Literary Discourse:A Study of the Implicit Conceptual Metaphor in Somerset Maugham's Rain显示文摘This paper looks into the implicit conceptual metaphor in the short story Rain by Somerset Maugham from a cognitive-functional perspective. The word 'rain',with its unusual frequency of occurrence and used in a less common clause structure in the discourse,is obviously foregrounded. But rain is not what the story is about,it is about the protagonist,a missionary,Davidson by name and his relationship with a woman named Thompson. Rain is used symbolically as the source domain,but where is the target domain? The recurrence of 'the rain',which forms a metaphoric chain,moves the narrative through its entire structure,beginning with Orientation,through 11 phases in Complication Actions until it reaches Resolution,which takes the form of Davidson's suicide. The ending comes as a surprise to the reader and forces him to look back and re-contextualize the story on the basis of a series of counter-expectancies and linguistic expressions so that he finds the relationship between Davidson and Thompson was not one between a preacher and a sinner,but one between a man and a woman. Linguistic analysis and cognitive analysis bring to light the fact that what made Davidson behave the way he did was not only his religious fanaticism but,more decisively,also his inner urge or desire,which turns out to be the target domain. The fascinating role metaphor and metonymy play in the unfolding of discourse makes it possible to establish the cross-domain mapping of knowledge about rain onto knowledge about desire,so the dominant conceptual metaphor,Desire Is Rain,finally takes shape. This is how the discourse realizes the conceptual metaphor. As the metaphor is implicit,it takes a lot of inferencing to see how the discourse realizes it as it unfolds,and how the metaphor shapes the meaning of the discourse as it gradually emerges. The target domain is implied in order to make the story stylistically unique and heighten the cognitive impact of the short story. | REN Shaozeng | 2016 | 外国语2016，39，5： | 2 |

| 14 | Numerical Study of the Effect of Imaginary Circle Diameter and Initial Flow Field on the Aerodynamic Field in a Tangentially Fired Furnace显示文摘In this paper, the effect of the imaginary circle diameter opi and the initial flow field on the aerodynamic field in a tangentially fired furnace was studied by numerical simulation and experiments in the cold model. Results show that merely reducing the imaginary circle diameter rki can not significantly reduce the rotatiollal diameter op in the range considered. The flow still rotates coullter-clockwise stably and does not change rotation direction when the direction of all jet axes are defiected suddenly to the opposite rotation direction by up to 5.4' in a countereclockwise llow field. It is the first time that the numerical sAnulation results were obtained which agreed quite well with this experimental phenomena qualitatively. The experimental data, i.e., the rotational diameter & and the maximum velocity on the syrnmetric central line of fUrnace Vm, are only a bit larger than the simulation results. It is shown that the initial flow field has an important influence on the aerodynamic field in the furnace. Other measures have to be taken as wel1 in order to reduce & to resist slagging and high temperature corrosion of furnace tubes. Moreover, a new kind of grid arrangement was proposed in this paper, which can reduce effectively the false diffosion at the exit zone of burner. | Zhu Tong Sun Shaozeng Xia Chunyi An Baizeng Wu Shaohua Qin Yukun(School of Energy Science and Engineering, Harbin Institute of Technology, 150001, Harbin, China)Ma Xichen(Haxbin Boiler Works) | 1997 | Journal of Thermal Science1997，6，2： | 1 |

| 16 | On the Age of the Dongtang Formation in the Hengyang Basin of Hunan and the Cretaceous and Tertiary Boundary显示文摘Since the coexistence of the Cretaceous and Palaeocene was ascertained in the Hengyang Basin of Hunan in the middle of the 1960’s, the Cretaceous and Tertiary boundary has been discussed in several papers, but it still remains controversal. The points at issue are the connotation, stratigraphical position and lateral correlation of the Dongtang (or Chejiang) Formation. | Guan Shaozeng Geological Institute for Chemical Mineral Products, Ministry of Chemical Industry, Zhuozhou, Hebei Jia Zhongpeng | 1989 | Acta Geologica Sinica(English Edition)1989，63，3： | 1 |
