AIM: To investigate the state of infection, replication site, pathogenicity and clinical significance of transfusion transmitted virus (TTV) in patients with hepatitis, especially in patients of unknown etiology. METHODS: Liver tissues taken from 136 cases of non-A non-G hepatitis were tested for TT virus antigen and nucleic acid by in situ hybridization (ISH) and nested-polymerase chain reaction (PCR). Among them, TT virus genome and its complemental strand were also detected in 24 cases of autopsy liver and extrahepatic tissues with ISH. Meanwhile, TTV DNA was detected in the sera of 187 hepatitis patients by nested-PCR. The pathological and clinical data of the cases infected with TTV only were analyzed. RESULTS: In liver, the total positive rate of TTV DNA was 32.4% and the positive signals were located in the nuclei of hepatocytes. In serus, TTV DNA was detected in 21.4% cases of hepatitis A-G, 34.4% of non-A non-G hepatitis and 15% of healthy donors. The correspondence rate of TTV DNA detection between liver tissue with ISH and sera with PCR was 63.2% and 89.3% in the same liver tissues by ISH and by PCR, *** double-strand probes and single-strand probes designed to detect TTV genome, the correspondence rate of TTV DNA detected in liver and extrahepatic tissues was 85.7%. Using single-strand probes, TTV genome could be detected in liver and extrahepatic tissues by PCR, but its complemental strands (replication strands) could be observed only in livers. The liver function of most cases infected with TTV alone was abnormal and the liver tissues had different pathological damage such as ballooning, acidophilia degeneration, formation of apoptosis bodies and focus of necrosis, but the inflammation in the lobule and portal area was mild. CONCLUSION: The positive rate of TTV DNA among cases of hepatitis was higher than that of donors, especially in patients with non-A non-G hepatitis, but most of them were coinfected with other hepatitis viruses.

基于Tersoff势描述的硅原子间相互作用,通过分子动力学方法模拟考察了在垂直于生长方向上分别对晶体施加了不同应变时,硅沿[100]和[112]晶向的晶体生长。结果显示,在压应变条件下,随着应变的增大晶体生长速率减小;而在拉应变条件下,在小应变范围内,晶体生长速率随应变增大并不减小,甚至还可能增大,只有当应变达到一定程度时,晶体生长速率才会随着应变的增大而减小;拉应变对[112]方向生长中液-固界面的形态也产生了显著影响。

The near-infrared responsivity of a silicon photodetector employing the impurity photovoltaic （IPV） effect is investigated with a numerical method. The improvement of the responsivity can reach 0.358 A/W at a wavelength of about 1200 nm, and its corresponding quantum efficiency is 41.1%. The origin of the enhanced responsivity is attributed to the absorption of sub-bandgap photons, which results in the carrier transition from the impurity energy level to the conduction band. The results indicate that the IPV effect may provide a general approach to enhancing the responsivity of photodetectors.

为了研究0.5mm厚的Ta-10W合金微束等离子弧焊过程中温度对焊接接头质量的影响,利用有限元分析软件ANSYS,对微束等离子弧焊温度场进行了数值模拟。模拟所得焊缝形状及尺寸与实验结果吻合较好,从而验证了所建有限元模型的可靠性。此外,还对焊接接头的质量进行了大量实验研究,分析了焊接温度与微观组织形态及表面显微硬度之间的关系。实验结果表明,焊缝未被氧化;晶粒主轴的成长方向随着最大温度梯度方向的变化而变化,从熔合线处开始垂直向焊缝中心生长,到最终与焊缝中心线重合;沿着焊接方向,焊缝金相组织大小与显微硬度有规律的不断变化;垂直于焊接方向,从焊缝中心到两边,金相组织逐渐变小。

In this paper, two types of silicon（Si） particles ball-milled from n-type Si wafers, respectively, with resistivity values of 1 Ω·cm and 0.001 Ω·cm are deposited with silver（Ag）. The Ag-deposited n-type 1-Ω·cm Si particles（nl-Ag） and Ag-deposited n-type 0.001-Ω·cm Si particles（n0.001-Ag） are separately used as an anode material to assemble coin cells,of which the electrochemical performances are investigated. For the matching of work function between n-type 1-Ω·cm Si（nl） and Ag, nl-Ag shows discharge specific capacity of up to 683 mAh·g^-1 at a current density of 8.4 A·g^-1, which is40% higher than that of n0.001-Ag. Furthermore, the resistivity of nl-Ag is lower than half that of n0.001-Ag. Due to the mismatch of work function between n-type 0.001-Ω·cm Si（n0.001） and Ag, the discharge specific capacity of n0.001-Ag is 250.2 mAh·g^-1 lower than that of nl-Ag after 100 cycles.
