21  High Resolution Volumetric Three-dimensional Display- state of the Art in Information Technology GENG Zheng Abstract: Institute of Automation, Chinese Academy of Sciences, Beijing 100080, China Abstract: As an important branch of information technology, display technology plays a significant role in the high technology development. Traditional information display technologies and devices confine the three-dimensional (3D) world into a flat two-dimensional screen. Lack of depth cues greatly limits the ability of human beings in perceiving and understanding the complexity of real-world objects. We propose herein a novel volumetric 3D display concept that offers high resolution 3D display. The viewers of the displayed images can see the displayed object without using any special eyewares. Key Words: three-dimensional display; high resolution CLC Number: G202  Document Code: A  Article ID: 1000-7857(2007)20-0021-06
27  Study on Pre-thrombotic States in Complex Diseases ABUDUREYIMU Shajidan, JIN Wei, AIZEZI Renaguli, et al. Abstract: The objective of this study is to reveal some common features of pre-thrombotic states in complex diseases. The methods used include the expression of CD62p on platelets, the level of plasma tissue plasminogen activator (t-PA) and its inhibiter (PAI-1), the level of endothelin (ET-1), activated partial thromboplastin time (APTT), fibrinogen (FIB),  prothrombin time (PT) and thrombin time (TT), which were tested by using Flow Cytometer, ELASA method, radioimmunoassay method and auto coagulometer. It is shown that, compared with the control group, the average expression of CD62P, the level of plasma PAI-1 in complex disease group are significantly increased (P<0.05); the level of t-PA in complex disease group is decreased; there is a significant increase in the level of serum ET-1 in the tumor group; however, there is no significant difference of ET-1 level between the control group and the rest complex disease groups (P>0.05); there is no significant difference of above indexes between disease groups (P>0.05); the APTT is significantly shortened in the complex disease group (P<0.05); the level of FIB is significantly increased in the complex disease group and the change is especially significant in the tumor group (P<0.05); PT is significantly shortened in tumor, diabetes and hypertension patients (P<0.05); there was no significant changes in APTT, PT, TT between disease groups (P>0.05). It is concluded that there is an increased platelet activation, thrombin activity, lower fibrinolytic function in complex disease patients; there is an obvious pre-thrombotic state in complex diseases; the pre-thrombotic state is one of the probable  common pathophysiological mechanisms of complex diseases. Key Words: complex disease; prethrombotic state CLC Number: R363  Document Code: A  Article ID: 1000-7857(2007)20-0027-06
33  Hydrogen Isotope Separation Using Temperature Programmed Desorption with Chromatographic Column XIE Bo, LIU Yunnu, WENG Kuiping, et al. Abstract: A series of hydrogen isotope separation experiments using temperature programmed desorption were carried out with chromatographic column, including half-saturation test, saturation test and enrichment test with low abundance samples. Experimental results show that the separation method using temperature programmed desorption enjoys high separation efficiency and big treatment capacity. The abundance ratio of D/H mixed gases reaches 30% from 0.1%, and more than 90% from 10%, the ratio is less than 10-5 in the depleted gas. The treated capacity reaches 70 m3/d. Key Words: temperature programmed desorption; hydrogen isotopes; chromatographic column; enrichment CLC Number: O643.14  Document Code: A  Article ID: 1000-7857(2007)20-0033-03
36  Experimental Study and Numerical Calculation on the Performance of Electrostatic Precipitators DANG Xiaoqing, REN Yan, MA Guangda, et al. Abstract: In this paper, the current density on the collecting plate is measured on 12 kinds of discharge electrodes combined with C480 and ZT24 collecting plates. The effect of different discharge electrodes and settings on the experiment results is discussed in terms of average current density and relative deviation. The distributions of electric potential and potential gradient at V type discharge electrodes combined with ZT24 collecting plate are calculated by using finite element method .Based on the results of the experiment and numerical calculation, the effect of potential gradient on the corona current is discussed. Key Words: electrostatic precipitator; distribution of current density; average current density; potential gradient at collecting plate; finite element method CLC Number: TQ172.6+88.1  Document Code: A  Article ID: 1000-7857(2007)20-0036-047
43  The Grooving Top-caving Method for Controlling Ground-pressure in the Gob-side Entry Retained LI Junping, LU Lianning, YU Huijun Abstract: The grooving top-caving method, a local grooving top-caving technique with controlled explosion, not only can economically reduce the continuous area of mining abandoned stope and separate it from the mining system at deep level, but also eliminate the hidden danger of large scale roof sudden falling, and redistribute the roof stresses to insure a safe production. In this paper, the characteristics of ground-pressure are studied at gob-side entry retained in Jixi Coal-mining Group Company. To control the ground-pressure in gob-side entry retained, a local grooving top-caving technique with controlled explosion is applied. The results show that the safe production is insured, and obvious economical benefit is obtained. Key Words: the grooving top-caving method/local grooving top-caving technique with controlled explosion; gob-side entry retained; ground-pressure; ground-pressure control CLC Number: TD853.391+.2  Document Code: A  Article ID: 1000-7857(2007)20-0043-05
48  Modeling of Clapboard Delay Device of Gasless Delay Composition by ANSYS FAN Fan, QIAO Xiaojing, SHI Shaomei Abstract: With respect to theoretical studies on gasless delay composition, the combustion model and computer software for delay composition are reviewed systematically. According to the hypothesis of the reaction combustion model of gas-solid phases and the spherical combustion model starting from a hot spot, the corresponding calculation of burning rate is carried out and the burning model empirical formula are obtained. The basis of theory and formula for delay burn rate codes (HARDT) is discussed, including the burning rate formula and the computing accuracy. ANSYS is used to establish a model to study the delay device with separated cavity. The results show that the temperature in the center of the clapboard is higher than that at the edges, and will first reach the ignition temperature of the igniter composition. The experimental values of delay time are compared with the predicted ones, and the error is about 10%.
