浅谈外墙保温粘贴苯板技术

我国是在20世纪80年代中期才开始进行外保温工程试点,对于外保温的发展起了很大的促进作用,由于烧结砖外贴苯板技术温在建筑节能和室内环境舒适等方面中能有效的消除热桥、保温效率高、热稳定性能好、增大使用面积、节能效率高等优点而成为目前我国北方寒冷地区主导的节能型墙体,非常适合于我国北方寒冷地区新建节能建筑和现有住宅建筑节能改造的墙体保温,是一种非常值得推广的外保温技术.     

“送课”岂如“送研”

时下,在推动新课程教学改革的进程中,在一些地区盛行由教研部门牵头,城区优秀教师"送课下乡""送课上门"活动,其目的就是让乡村学校的教师能够呼吸新鲜气息,学习新的教学方法,让其学有目标,用意良好。然而,最近我走访了一些乡村学校的教师     

原子、原子核常见错解分析

原子、原子核内容包括α粒子散射、能级、天然放射性现象、α射线、β射线、γ射线、核子、中子、质子、原子核、核能、质量亏损、裂变、链式反应、聚变等,以及原子核式结构、半衰期、核反应方程、爱因斯坦的质能方程等规律．所涉及的基本方法,由于知识点相对分散,要加强对物理现象本质的理解,运用逻辑推理的方法,根据已有的规律和事实、条件作出新的判断．在核能的计算时对有效数字的要求也很高。     

当体育中考遭遇兴奋剂

新闻:广州中学生网上发帖寻兴奋剂应对中考"广州中考体育救救命!""体育中考有兴奋剂检查么?""中考体育能不能吃兴奋剂?"今年,广州中考体育考试项目首次由200米取代50米跑,不少初三学生担心会发挥失利影响成绩,纷纷在网上交流增强体力的招数,使用"兴奋剂"的心得,何处能购买到"兴奋剂"。有网友干脆调侃说,可以上网看看美女,刺激肾上腺分泌,提高成绩。     

Novel distribution pattern of fibrinolytic components in rabbit tissues extract： a preliminary study

Objective: The purpose of this work was to investigate the distribution pattern of fibrinolytic factors and their inhibitors in rabbit tissues. Methods: The components of the fibrinolytic system in extracts from a variety of rabbit tissues, including tissue plasminogen activator (tPA), plasminogen activator inhibitor-1 (PAI-1), plasminogen (Plg), plasmin (Pl) and α2 plasmin inhibitor (α2PI), were determined by colorimetric assay. Results: The tissue extracts in renal, small intestine, lung, brain and spleen demonstrated strong fibrinolytic function, in which high activity of tPA, Plg and Pl was manifested; whereas in skeletal muscle, tongue and stomach, higher activity of PAI-1 and α2PI showed obviously. Also excellent linear correlations were found between levels of tPA and PAI-1, Pl and α2PI, Plg and Pl. In related tissues, renal cortex and renal marrow showed distinctly higher activity of tPA and lower activity of PAI-1, with the levels of Plg and Pl in renal cortex being higher than those in renal marrow, where the α2PI level was higher than that in renal cortex. Similarly, the levels of tPA, Plg and Pl in small intestine were higher than those in large intestine, but with respect to PAI-1 and α2PI, the matter was reverse. In addition, the fibrinolytic activity in muscle tissue was lower, however, the levels of tPA, Plg, and Pl in cardiac muscle were obviously higher than those in skeletal muscles, and the levels of PAI-1 and α2PI were significantly lower than those in skeletal muscle. Conclusion: Our data demonstrate that a remarkable difference of the fibrinolytic patterns exists in rabbit tissues, which has probable profound significance in understanding the relationship between the function of haemostasis or thrombosis and the physiologic function in tissues.
