分别以TiH2,ZrH2为原料,结合原位反应与脉冲电流辅助烧结制备了TiB2-SiC及ZrB2-SiC复相陶瓷。研究发现,所制备的复相陶瓷表现出一定的织构化现象,TiB2及ZrB2晶粒在反应烧结过程中其(001)面沿垂直压力和电流方向生长。金属氢化物粉体的粒径大小对复相陶瓷的致密化及微结构有较大影响:粒径越小越有利于陶瓷的致密化和硼化物晶粒的定向生长。由于金属硼化物的定向,复相陶瓷的机械性能表现出各向异性。TiB2-SiC复相陶瓷具有较高的断裂韧性,最高可达7.3 MPa.m1/2,而ZrB2-SiC复相陶瓷具有更高的抗弯强度(937 MPa)。

提出一种考虑噪声影响基于改进损伤识别因子和遗传算法的结构损伤识别方法。介绍结构损伤识别的参数化思想,并提出一种考虑不同模态信息和权重系数的损伤识别因子。在选择算子、交叉算子、变异算子以及自适应交叉和变异等方面对遗传算法进行改进,并在无噪声情况下,对一简支梁和连续梁进行了损伤识别,识别效果非常好,验证了方法的正确性和有效性。分别考虑随机噪声和高斯白噪声对简支梁进行损伤识别,发现该方法在噪声水平不很高情况下,识别效果很好。最后,在一钢框架基准有限元模型基础上,考虑四种损伤工况进行损伤识别,识别结果较好,该方法能够很好地应用于结构的损伤识别和健康监测。

提出了一种基于应力波因子的金属材料表面塑性损伤检测方法。将AZ31镁铝合金试件加载到不同的拉伸载荷后,利用Ritec SNAP非线性超声测试系统激发和接收Rayleigh表面波,通过实验测试在不同载荷作用后基于应力波因子的声学非线性系数与应力的关系。研究结果表明,当加载应力接近材料的屈服极限时,基于应力波因子的声学非线性系数随着应力的增加明显增大,因此可以利用基于应力波因子的声学非线性系数对金属材料表面的塑性损伤进行非线性超声无损评价。

AIM: To develop a hepatocyte cell line, we immortalized primary porcine hepatocytes with a retroviral vector SSR#69 containing the Simian Virus 40 T antigen (SV40T ag). METHODS: We first established a method of porcine hepatocyte isolation with a modified four-step retrograde perfusion technique. Then the porcine hepatocytes were immortalized with retroviral vector SSR#69 expressing SV40T and hygromycin-resistance genes flanked by paired loxP recombination targets. SV40T cDNA in the expanded cells was subsequently excised by Cre/LoxP site-specific recombination. RESULTS: The resultant hepatocytes with high viability (97%) were successfully immortalized with retroviral vector SSR#69. One of the immortalized clones showed the typical morphological appearance, TJPH-1, and was selected by clone rings and expanded in culture. After excision of the SV40T gene with Cre-recombinase, cells stopped growing. The population of reverted cells exhibited the characteristics of differentiated hepatocytes. CONCLUSION: In conclusion, we herein describe a modified method of hepatocyte isolation and subsequently established a porcine hepatocyte cell line mediated by retroviral transfer and site-specific recombination.

The method used in our previous papers is adopted to estimate four basic parameters （the central black hole mass （M）, the boosting factor （or Doppler factor）（6）, the propagation angle （Φ） and the distance along the axis to the site of the γ-ray production （d）） for 59 γ-ray loud blazars （20 BL Lacertae objects and 39 flat spectrum radio quasars）. The central black hole masses estimated for this sample are in a range of from 107 Me to 109 MG. In the case of black hole mass, there is no clear difference between BL Lacertae objects and flat spectrum radio quasars, which is consistent with the previous results suggesting that the central black hole masses do not play an important role in the evolutionary sequence of blazars.
