Here we presented a novel technology to achieve a Super-hydrophobic coating with microscopic roughness on copper surface. First, make a layer of verdigris grow on the fresh pure copper surface. Gain it by exposing the copper to air and the mist of acetic acid solution. The green coating is a mixture of basic copper（II） carbonate and copper（II） acetate. Second heat the coating and make it decompose to CuO. Lastly, form an n-octadecanethiol self-assembled monolayers coating on the outermost surface. Contact angle test, scanning electron microscope analysis and electrochemical testing were carded out to characterize the surface, and a heat transfer experiment for dropwise condensation of steam was performed also. Results show that the modified surface bears a few Super-hydrophobic features, the static contact angle is higher than that in literatures, reaching 153.1±1.7°. The microscopic roughness can be seen in SEM images, differing much from H2O2 etched surface and bare copper surface. The condensation of steam on the surface is a typical form of dropwise condensation, in the measured range of temperature difference, under 0.1 MPa, the average convection heat transfer coefficients of the vertical surface are 1.7-2.1 times for those of film condensation. At the same time, the inhibition efficiency of surface is improved to some extent comparing with the same kind of SAMs, which suggests that the lifetime of maintenance dropwise condensation would have the possibility to surpass the existing record.

“没有财产权就不能保护社会财富、资源和劳动”的“财产权的效率观点”,是个抽掉了人力产权这一产权本质内核的壳命题。财产权的效率以人力产权权能和权益的充分实现为前提。而人力产权权能和权益的充分实现基于社会基本经济制度和人力产权所有者对其人力产权运用的把握和认知。历史证明,唯有排除凭借生产资料私人垄断实现对他人剥削可能的社会主义公有制为主体的社会经济制度,才能真正保障劳动大众的权益并提供人力产权权能得以充分实现的基本条件。全盘私有化产权改革倾向不具有任何历史必然性,私有产权神话有诱导中国落入“和平演变”陷阱的危险。

Objective： To investigate the clinical significance of survivin in endometrial carcinoma and to investigate the relationship between the expression of survivin and Ki-67. Methods： Immunohistochemical S-P （streptavidin-biotin-peroxidase complex）method was performed to detect the expression of survivin and Ki-67 antigen in 15 cases of normal endometrium, 21 cases of endometrial simple and complex hyperplasia, 22 cases of endometrial atypical hyperplasia, and 61 cases of endometrial carcinoma. Results： Survivin was hardly detected in some normal endometrium in the proliferative phase and in the secretory phase. However, the level of survivin expression in atypical hyperplasia endometrium（72.73%）was higher than that in normal en- dometrium （7.14%）（P 〈 0.05）, including simple and complex hyperplasia （42.38%）（P 〈 0.01 ）, and was lower than that in endometrial carcinoma（90.17%）（P 〈 0.05）. Moreover, significant correlation was present between the expression of survivin and the characteristics of endometrial carcinoma, including clinical stage, histological grade and the presence of invasion to myometrium （P 〈 0.05）. In addition, Ki-67 antigen expression was positively correlated with survivin expression in all specimen. Ki-67 labeled indexes （LIs）in hyperplasia endometrium were significantly lower than those in atypical hyperplasia endometrium and endometrial carcinoma （P 〈 0.01 ）, while there was no significant difference in Ki-67 LIs between atypical hyperplasia endometrium and endometrial carcinoma（P 〉 0.05）. There was no significant relationship between Ki-67 LIs and the characteristics of endometrial carcinoma, including histological grade, clinical stage or the invasion to myometrium（P 〉 0.05）. Conclusion： Survivin may participate in the onset and progression of endometrial carcinoma through inhibiting apoptosis and promoting proliferation. Survivin expression is correlated with the malignant degree and prognosis of tumor. Ki-67 is also associated with carcinogenesis
