红色5月,和风徐徐,朗朗天空,山青水秀…… 我们来到了邓小平同志曾题词“镜泊胜景”、叶剑英元帅曾题诗:“山上平湖,水上山;北国风,胜江南”的国内外驰名的黑龙江省宁安市境内的高山堰塞湖——镜泊湖。 那湖光山色,美丽可人的景致,让你留连忘返。 中午时分,我们来到刘少奇同志1964年曾下榻的“哈尔滨工业大学镜泊湖休养所”6栋稍事休息。客厅左角圆茶几上的长木箱里的竹制两节带轮的钓鱼竿和《贺老总的钓鱼竿》说明立即引起了我们的兴趣。 《贺老总的钓鱼竿》介绍:“1964年夏天,贺老总来到了镜泊湖。接待单位忙着要给贺老总做鱼吃。贺老总说:‘到了镜泊湖,我要吃自己钓的鱼, 相似文献

The preparation of calcium phosphate (CP) coating on alumina ceramics using electric pulse stimulating method has been investigated. The cup-shaped alumina ceramics were soaked in a simulated body fluid ( SBF), and a square pulse potential with frequency of 1 Hz and voltage of 110 V was applied between the inner and outer surfaces of the alumina cup. Surface morphology of CP coatings during different deposition periods was observed by a Philips XL-30 scanning electron microscope (SEM). Compositional analysis was examined by EDAX. The mechanism of nucleation and growth of CP coating was discussed. SEM result indicates that the coating comprises of a large number of tiny needle-like grains and has a porous microstructure. There is a strong bond between the deposited layer and Al2O3 substrate, which may be due to the gentle growth of the biomimetic method. The EDAX analysis indicates that main composition of the coating is calcium and phosphor. The formation of CP coating may be contributed to the stimulation of electric pulse and the high ions concentration which is 1.5 times of the concentration of SBF solution ( 1.5SBF solution). Such surface functionalization method by electric pulse potential can be used to prepare CP coating on various electric-insulating bioinert materials for improving their bioactive character. 相似文献
