Gold films deposited by direct current magnetron sputtering are used for synchrotron radiation optics. In this study, the microstructure and surface roughness of gold films were investigated for the purpose of developing high-reflectivity mirrors. The deposition process was first optimized. Films were fabricated at different sputtering powers (15, 40, 80, and 120 W) and characterized using grazing incidence X-ray reflectometry, X-ray diffraction, and atomic force microscopy. The results showed that all the films were highly textured, having a dominant Au (111) orientation, and the film deposited at 80 W had the lowest surface roughness. Subsequently, post-deposition annealing from 100 to 200℃ in a vacuum was performed on the films deposited at 80 W to investigate the effect of annealing on the microstructure and surface roughness of the films. The grain size, surface roughness, and their relationship were investigated as a function of annealing temperature. AFM and XRD results revealed that at annealing temperatures of 175 ℃ and below, microstructural change of the films was mainly manifested by the elimination of voids. At annealing temperatures higher than 175℃, grain coalescence occurred in addition to the void elimination, causing the surface roughness to increase.

Indica-japonica hybrid rice(Oryza sativa L.) cultivars showed high yield potential and poor tasting quality when compared with common japonica rice cultivars. Large panicle is a prominent factor of high yield for indica-japonica hybrid rice cultivars, and the panicle weight varies greatly among different indica-japonica hybrid rice cultivars. It is important to research on yield and grain quality of different panicle weight indica-japonica hybrid rice cultivars. In this study, two different panicle types indica-japonica hybrid cultivars were used to research on the relation of yield and grain quality. The yields of two heavy panicle weights indica-japonica hybrid cultivars were significantly higher than that of two medium panicle weight rice cultivars. The cooking and eating quality and starch properties of different panicle type cultivars were evaluated. Yongyou 6715(medium panicle) and Yongyou 1852(heavy panicle) got the relatively higher cooking and eating quality. Rice cultivars with medium panicle weight had more large starch granules and higher relative crystallinity than cultivars with heavy panicle weight. Transition temperature and retrogradation enthalpy(ΔHret) of medium panicle type cultivars were significantly higher than that of heavy panicle type cultivars. There was no significant difference in amylose content among different panicle type cultivars. Protein content of heavy panicle type cultivar was higher than that of medium panicle type cultivar, and protein content is the main factor affect cooking and eating quality in this study. The cultivar Yongyou 6715 got the highest taste value with the lowest protein content. Thus, it is suggested that the emphasis on improving rice cooking and eating quality of indica-japonica hybrid rice cultivars is how to reduce the protein content in rice grain. According to the results of this study, medium panicle type with high grain weight is the desired panicle type for high quality indica-japonica hybrid rice bre

In a time of the global market economy, if one wants to live harmoniously together with nature or living environment, he should not think with a theoretical mode of dualist contradiction but that of harmony and coexistence such as ＂wholeness of man and nature＂. To illustrate this point, this paper thinks The Woman Warrior and Ballad of Eternal Sorrow are two significant texts： Ballad of Eternal Sorrow tells an ordinary, self-respecting, and life-respecting story of WANG Qi-yao and the girls like her as well as the city Shanghai. They blend into one harmonious whole： The city is like the girls and the girls match the city. Likewise, The Woman Warrior highlights the significance of naturc on the girl narrator＇s epiphany and healthy growth. The narrator comes to understand that paradoxes are the basic existent condition of human beings and so what she needs to do is to be magnanimous and balanceable in accepting these paradoxes.

Background Cryopreserved conduit valved homografts （CVH） have been widely used in surgical treatment of cardiac disease. This study aimed to determine the extent of host cell ingrowth and the durability and immunogenicity of CVH,and to compare the performance of CVH stored at 4℃ and CVH cryopreserved in liquid nitrogen at -196℃.Methods Heterotopic transplants of canine CVH stored at 4℃ （n=14） and cryopreserved in liquid nitrogen （n=14） were made onto the abdominal aorta of recipient dogs. Animals were sacrificed at 7 and 15 days and at 1, 3, 6, 9, and 12months after transplantation to excise the implanted CVHs. Tissue DNA extraction and quantitative polymerase chain reaction （PCR） were performed to calculate the ratio of donor cells and host cells in the CVH. The tissue viability of CVH after implantation was analyzed by detecting alkaline fibroblast growth factor 2 （FGF-2） using immunohistochemical staining and by observation under transmission electron microscope and scanning electron *** All the animals survived and recovered well. There were few repopulating host cells （0.04-0.83%） in the implanted CVH at 7 or 15 days. The ratio of ingrowing host cells into the CVH continued rising after implantation and reached 40%-47% in the 12th month postoperation. Histology, transmission electron microscopy and FGF-2immunohistochemical staining indicated that fibroblasts and the host＇s endothelial cells were the main cellular elements invading the CVH. There were no significant differences in results between CVH stored at 4℃ and CVH cryopreserved in liquid *** Host cells growing into CVH are very important for maintaining the long-term structure and function of the implanted CVH. There is no significant difference between CVH storing at 4℃ or in liquid nitrogen in regard to the ingrowth of host cells or of morphologic features after CVH allografting.
