The understanding of the behavior of chlorine in silicon is useful for several applications, for example, plasma etching of silicon, a proposed technique for electronic device development. In the present study, specimens of silicon (p-type) were implanted at room temperature with chlorine ions to four successfully increasing doses of 1×1015(40 keV and 80 keV), 5×1015(100 keV), 1×l016(100 keV), and 5×l016(100 keV) Cl+ ions/cm2.

研究了用于核反应堆低放射性结构材料 Fe- Cr- Mn( W,V)奥氏体钢。通过 ( C+ N)复合强化有效地提高 Fe- 1 2 % Cr- 1 5% Mn( W,V)钢高温强度和蠕变断裂寿命 ,并改善高温塑性。在温度 673K以下 ,该合金比 SUS31 6钢和 JPCAS钢强度和塑性优良。合金强度和塑性与形变温度的相互关系是和合金形变组织变化密切相关。对 673K以上塑性降低的原因进行断口和显微组织分析 ,控制晶界碳化物粗化是进一步提高高温塑性的主要途径。

利用氦离子(he+)束和电子(e-)束双束同时辐照化学溶胶法制备的新型12Cr-ODS铁素体钢。实验结果表明,辐照初期,随着辐照剂量增加,点缺陷团(黑斑)在基体内形成,密度不断增大,尺寸长大缓慢,辐照剂量为0.8 dpa时形成间隙型位错环。不同试验温度下,辐照均产生小尺寸高密度的空洞,随着辐照剂量增加,空洞尺寸长大缓慢,空洞密度降低也缓慢,辐照剂量达15 dpa时,空洞肿胀均小于0.05%,表明12Cr-ODS铁素体钢具有良好抗辐照损伤性。

Experimented results showed that energetic ion induced phase change in a solid could be achieved not only by irradiation at high fiuences but also by singe ion induced huge electronic excitations. The phase change produced in the later condition is just along individual ion latent tracks. Recently, we have proposed a novel technique, "low energy ion implantation + swift heavy ion irradiation", for synthesizing new structures in

A high angular resolution near-infrared image that shows the intensity of polarization for the GG Tau A binary system was obtained with the Subaru Telescope. The image shows a circumbinary disk scattering the light from the central binary. The azimuthal profile of the intensity of polarization for the circumbinary disk is roughly reproduced by a simple disk model with the henyey-Greenstein phase function and the Rayleigh function, indicating there are small dust grains at the surface of the disk. Combined with a previous observation of the circumbinary disk, our image indicates that the gap structure in the circumbinary disk orbits counterclockwise, but material in the disk orbits clockwise. We propose that there is a shadow caused by material located between the central binary and the circumbinary disk. The separations and position angles of the stellar components of the binary in the past 20 yr are consistent with the binary orbit with a = 33.4 AU and e = 0.34.
