In this paper, the quality of unstructured grids generated by Delaunay Triangulation Method and Bubble Packing method is compared by the classical lid-driven square cavity flow solved by SIMPLE algorithm on collocated unstructured grid. The velocity distributions on vertical and horizontal center lines are in good agreement with bench mark, which shows that both of the two grids can be used in CFD.

The results of interior ballistic theoretical simulationindicates that the single PSS charge application need propellants be provided with upperburning rate, adopting PSS and traditional model frame propellants commix charge is apractical applied technique approach.. By optimizing the PSS model frame parameter, wecan obtain "flat roof" domino offect with better even peak value "double peak" p-tcurve. Comparing with current 19 hole propellants charge with the best increasing burningsurface characteristic, the muzzle velocity of projectile can be enhanced about 55m/s, andthe instruct pressure efficiency can be enhanced about 5.7％.

While the market is booming, the discussion of interest transfer and redistribute in the issue of convertible bonds is slight. In the second half of 2003, the Merchants Bank Convertible Bonds Event broke this equability and cause on the market discussion on the protection of the circulating shareholders' rights.

与市场上投资者追捧可转债的热潮相比，对我国可转债的相关者利益转移和再分配的讨论略显冷淡。2003年下半年沸沸扬扬的"招商银行可转债事件"却打破了这一平静，引发了市场上对流通股股东权益保护的讨论和反思。

The current research points out that for the CFCHS joints the linear extrapolation method can be used for chords,whereas the quadratic extrapolation method must be used for braces.The hot spot stress distributions on the CFCHS joints tend to be more uniform and their SCFs become smaller significantly,compared with the CHS joints.Axial tension on the brace puts the CFCHS joints at a disadvantage,which produces higher SCFs than axial compression.The effects of nondimensional geometric parameters β,τ and γ on SCFs of the chords of the CFCHS joints are basically the same as those of the CHS joints,but for the braces,there is a bit difference in the effects of parameters β,τ and γ between the two kinds of joints.Concrete has the function of improving the CFCHS joint rigidity and then decreasing SCFs which is expected to increase fatigue strength,but concrete strength grade does not exert significant influence on SCFs.

研究表明：CFCHS节点的热点应力，对主管可采用线性外推方法，对支管需采用二次外推方法；相比CHS节点，CFCHS节点的热点应力分布趋于均匀，SCF显著减小；CFCHS节点支管轴向受拉比受压不利，SCF增大；CFCHS节点几何参数β，τ，γ对主管SCF的影响效应与CHS节点基本一致，但是对支管SCF的影响效应与CHS节点有些差异；混凝土的作用主要是改善CFCHS节点刚度，从而降低SCF，并预期可提高疲劳强度，但混凝土自身强度等级的高低没有显著影响节点的SCF。

Quantification of tissue heterogeneity at the infarct periphery was strongly associated with inducibility for monomorphic ventricular tachycardia (noninducible versus inducible: 13±9 versus 19±8 g, P=0.015) and was the single significant factor in a stepwise logistic regression.

Based on these results and inferred to related reports from other labratories, it was possible to make some analyses and conclusions or inferrences:(1) CD〓AK with tumoricidal activity were induced and expanded in number througth costimulation of PBMC with anti-CD〓 McAb . and r IL-2 ;(2) CD〓AK induced and expanded in such manner did exibit more potent proliferation·ability and cytotoxicity which maintained for lonser time than those of LAK cells, thus CD〓AK was a new variety of antitumor effector cells worth to be explored;(3) CD〓AK could mediate MHC nonrestricted cytotoxicity and kill tumor target cells through inducing necrosis and apoptosis;(4) Normal mature lymphocytes of PBMC could be induced to proliferate and /or to die from apoptosis when they were costimulated by anti-CD〓McAb and rIL-2. Both proliferation and apoptosis were existing in the same cultivation system sugsesting that the presence of rIL- 2 might provide some accessary signals for apoptosis.

以这些结果为基础并参考其它有关文献可能做出如下分析与结论或推论：(1)用抗CD〓单抗和rIL-2共刺激外周血单个核细胞能诱生扩增出具有杀瘤活性的CD〓AK细胞，(2)与LAK相比，用这种方法诱生扩增的CD〓AK增殖能力强、细胞毒活性强而且维持时间长；CD〓AK是一类值得开发的抗瘤效应细胞；(3)CD〓AK能够介导MHC非限制性细胞毒活性，可以通过诱导靶细胞坏死和/或凋亡杀伤肿瘤细胞；(4)正常外周血单个核细胞中的成熟淋巴细胞在受到抗CD〓单抗和rIL-2共同刺激后既可诱导增殖也可诱导凋亡，两者并存于同一体系，推测rIL-2的存在可能为细胞凋亡提供一些辅助信号。

Bubble nucleating and porosity were improved by adding lignin granule, and cell size of the polyurethane foam was decreased. Not only physical property but also thermal property of the material were enhanced. Compared with soft polyurethane foam, tensile strength of lignin reticulated polyurethane foam was raised by 140% at most which lignin content was 5%, and the heat-degradation temperature at the first stage was 50℃ more than soft polyurethane foam which lignin content was 10%. There had been a great improvement in heat resistance of the material. It was showed that weight of biological film reached to 10000 mg/L and 12100 mg/L when the lignin content of the polyurethane foams was 5% and 8% respectively via 30-day biofilm formation testing.

The outstanding feature of the new cutting dynamometer contrary to other type of dynamometer sensor is that it is more similar to general lathe tool. It can be installed on knife rest, so it is same wit practice state of cutting. Sensitivity of dynamometer is more high, especially main cutting force can attain 7.4pC/N. The calibration results show that it has high static linearity, and its natural frequency is greater than 5 kilohertz, so the cutting dynamometer has fully reached the dynamometer standard stipulated by CIRP-STCC.Finally, in order to measure the cutting force, the orthogonal experiment method in which the three factors are the diameter of cutting, feed and spindle speed is performed.
