This project was established based on the first cooperative development of optical in situ real time detecting technique probing the atomic scale layer-by-layer epitaxy growth of oxide film. Over the last three years, we have given full play to the advantages and characteristics of both sides and have finished the assumptions and plans of this subject satisfactorily. 1. In Institute of Physics, we set up advanced oblique-incidence reflectivity difference equipment and wrote one data acquisition procedure that made the simultaneous detection of optical signal and RHEED signal into reality. 2. The first observation of sustained oscillations over hundreds of monolayers in both real and imaginary signals during the epitaxy growth of SrNb0.1Ti0.9O3 on SrTiO3 substrate in LMBE testifies that oblique-incidence is an excellent method to detect and monitor film epitaxy growth real time. 3. For the first time, we verify that oblique-incidence reflectivity difference method can be used to monitor the layer-by-layer growth mode during continuous growth through the correspondence between optical signals to atomic or molecular step edge density on the growth surface. 4. Phenomenological analysis shows that optical signals comprise three parts, the first is proportional to the average thickness of the film and depends on the bulk phase dielectric response; the second is proportional to the coverage of terraces and depends on the dielectric response of atoms or unit cells in the terrace; the third is proportional to the coverage of step edges and depends on the effective dielectric response of atoms or unit cells at step edges. This makes oblique-incident reflectivity difference technique a quantitative macroscopic method to monitor film growth.
中文摘要:本课题是在合作首次发展了氧化物薄膜原子尺度层状外延生长光学原位实时探测方法的基础上立项的,三年来,我们充分发挥双方的优势和特点,圆满完成了课题的设想和计划。1、在物理所建立了一套先进的光反射差法装置,编写了计算机系统的数据采集程序,实现了两路光学信号和RHEED数据的同步采集和显示。2、用激光分子束外延在SrTiO3基底上生长SrNb0.1Ti0.9O3薄膜,首次观测到连续外延几百个原胞层,周期振荡的光反射差实部和虚部信号,证明了光反射差法是一种能原位实时探测与监控薄膜层状外延生长的好方法。3、首次验证了通过对生长表面原子或分子台阶密度的响应,光反射差法可用于原位实时监测在连续生长条件下薄膜的层式生长模式。4、通过唯象理论的研究,证明光反射差信号由三项组成,第一项只与薄膜的平均厚度和宏观光学电介质常数有关;第二项与分子台阶面覆盖度和台阶面上分子层的光学电介质常数有关;第三项与台阶边缘的覆盖度成正比,并和在台阶边缘的分子的有效光学介电常数有关。

CuS and CdS nano-particulate films were obtained with these two methods, and some interesting phenomena were observed: under the Gibbs film formed by CTAB, CuS nano-rods were obtained at the oil/water interface, and disklike aggregates of CdS nano-crystals were obtained at both the air/water and oil/water interfaces; under the Langmuir film formed by NaAOT at air/water interface, disk-like aggregates of CdS were also obtained.

The microstructure of MDF and MDF tested were studied. The results showed that the fibers in MDF are arranged randomly. Some of them arranged separately, most of them arranged in bundles. There are many blind holes between the fiber cells in MDF. The damage of MDF's compressive creep is the result of new cranny occuring, spreading and the combination of old cranny. In the repressing process, besides the pressure, heat is also the main factor on the damage of MDF, which can accelerate the adhension layer to deteriorate and lead to the gule strength decreasing.
结果表明:MDF的纤维排列无规则,纤维排列形态除少量纤维呈单根状外,大量的纤维以纤维束的形态排列;纤维之间存在许多大小不等的孔洞,呈不贯通状;MDF蠕变损伤是不断萌生新的裂隙并扩展和合并原有裂隙的结果;MDF二次加工过程中,除了压力是破坏MDF结构的主要因素外,加热温度使MDF胶层老化,胶合强度下降,也是破坏MDF结构的主要因素;MDF的破坏形态除了有纤维拉断外,还有纤维拔出和胶粘剂脱落。

A 46-year-old man presented with a gradually growing nodule on the left dorsal foot, which had been present for over 10 years. In the beginning, the lesion was treated as a keloid. Because of poor response to treatment, biopsy was arranged. Sections showed a dermal tumor composed of numerous foamy cells, hyalinized wiry collagen, spindle cells and entrapped collagen. The foamy cells were positive for KP1(CD68) and negative for S-100 protein and HMB-45. The histological and immunohistochemical results were consistent with the diagnosis of lipidized fibrous histiocytoma.
