高职院校经管类专业工学结合实现形式研究

高职教育的目标是培养适应生产、建设、管理和服务第一线需要的高技能人才。这一目标仅靠学校教育是难以实现的,必须走“校企合作、工学结合”的道路。探索高职经管类专业工学结合的实现形式,以有效解决学生的实习和就业问题、学校的教育资源紧张问题及企业的用人难问题。为高职经管类专业找到一条可持续发展之路。     

化学共沉淀法合成纳米Nd：YAG陶瓷粉体

以碳酸氢铵为沉淀剂,采用化学共沉淀法合成出多晶Nd：YAG纳米陶瓷粉体．采用XRD,SEM,BET等测试手段对粉体的相组成和微观结构进行表征,研究了煅烧温度、反应温度、Al（NO3）3浓度对粉体形貌、粒径以及分散性的影响．结果表明：前驱体在900℃煅烧2h直接生成Nd：YAG,并且随着煅烧温度的升高,粉体粒径逐渐变大,1100℃时煅烧所得粉体的平均粒径约为70nm．反应温度为30～40℃、硝酸铝溶液浓度为0．1～0．2mol／L时,所得粉体为球形或类球形,分散性最佳．     

蕴涵着魔化力量的诗的语言——漫论洛夫诗的语言艺术

诗歌是语言的艺术,诗的语言能使诗有别于或超越现实世界,从而达到超验的完美境界.台湾诗人洛夫十分注重营造、熔铸诗的语言,把现实陌生化,从而创造全新的审美时空.而且擅于运用比喻、象征、联想、韵律、含蓄等必要的技巧,将生活语言提升为诗的语言.此外,诗人还善于吸收中国古典诗歌的传统并运用于现代诗的创作,并且创造了新的诗体"隐题诗".

佛经刻写与中国书法艺术的发展

佛教传入我国以来,高僧和其他书法家以佛教经典文化作为书法书写的主要内容,其目的是书写佛经作功德、作供养。修心养身,净化心灵。从而推动了书法艺术的发展,也留下了浩如烟海的碑帖。同时。书法艺术也弘扬了佛法。两者相辅相成,共同发展,共同进步。

Effects of dietary fresh fermented soybean meal on growth performance,ammonia and particulate matter emissions,and nitrogen excretion in nursery piglets

This study was conducted to investigate the effects of fresh fermented soybean meal (FSM) on the growth performance of nursery piglets, nitrogen excretion in feces, and the concentrations of ammonia (NH₃) and particulate matter (PM) in the piggery. A total of 472 nursery piglets (Landrace×Yorkshire, (16.3±0.36) kg body weight) were randomly allocated into two treatments with 236 pigs in each treatment. The pigs were fed the basal diet without fresh FSM (control) or diet containing 10% (100 g/kg) fresh FSM (FSM group), and the crude protein content of the two groups was consistent. The feeding trial lasted for 28 d. The results showed that the pigs fed fresh FSM had increased (P<0.05) average daily gain (ADG) compared with the control. There was no significant difference (P>0.05) in feed to gain ratio (F:G) between the two groups. During the whole experiment, the concentration of NH₃ in the piggery decreased (P<0.05) by 19.0%, and the concentrations of PM (PM₁₀ and PM_2.5) in the piggery decreased (P<0.05) by 19.9% and 11.6%, respectively, in the FSM group, compared with the control. The ammonia nitrogen and nitrite content in feces increased (P<0.05) by 32.9% and 28.4%, respectively, in the FSM group. The fecal pH declined (P<0.05) significantly in the FSM group compared with the control. At the end of experiment, total protein (TP) concentration was increased (P<0.05) significantly and blood urea nitrogen (BUN) concentration was decreased (P<0.05) for pigs fed the diet with fresh FSM. The results indicated that dietary fresh FSM not only improved the growth performance of nursery piglets, but also reduced the NH₃ concentration in the piggery due to nitrogen conversion, and decreased the concentrations of PM₁₀ and PM_2.5 in the piggery.
