静脉穿刺成功因素的体会

在临床治疗与应急抢救过程中，静脉穿刺是一项最频繁而又最普遍的手段之一。特别是抢救危重病人及急慢性患者补给药物、营养、血液等的一个重要途径。所以对于静脉穿刺成功与否，在治疗和抢救过程中起着重要作用。现将多年临床静脉穿刺中摸索到的一些经验和体会总结如下：     

阑尾根部穿孔并阑尾周围脓肿的Ⅰ期手术治疗

胫骨骨折不愈合外固定架治疗体会

在四肢长管状骨骨不连中，胫骨骨不连发生率很高，尤其胫骨中下段最为多见。我院从2000年5月-2004年12月，采用小腿半环外固定架，植骨治疗，取得较好疗效，现报告如下。     

浅谈特殊教育中的游戏治疗

游戏治疗作为特殊儿童心理行为障碍的主要方法之一,它是利用游戏机制与心理学理论相结合,应用于特殊儿童身上的心理治疗方法。游戏治疗法可以让特殊儿童在游戏中获得积极的体验,培养特殊儿童的主动性,提高特殊儿童与他人的交流兴趣。从游戏治疗、游戏治疗的发展、技巧及优势做一总结,并阐述游戏治疗对特殊儿童的意义。     

让音乐徜徉在课堂中

面对低年级学生,该怎样让他们喜欢上课堂,爱上很多人认为枯燥的语文课?把音乐融入语文文本,为每一篇课文找一首与之相配的音乐,让文本为旋律填词,让音乐为文本谱曲。音乐,在语文课堂上发挥了巨大的作用:音乐让学生爱上了文本,音乐让学生体会到了文本的意境,音乐让孩子体验到了文本的情感,音乐让学生的朗读韵味十足。让音乐徜徉在语文课堂吧,它能让课堂充满艺术的气息,它会让课堂更具有情感的活力。     

如何在小学音乐教学中有效落实情感教育目标

作为一门独特的学科,音乐教学最核心的目标便是培养学生对音乐的理解、感悟以及审美等综合能力,并在学习过程中获得情感方面的陶冶。从这一点看,小学音乐教育更应该侧重于情感教育,它需要的是源自内心的情感投入。但是,纵观当前的小学音乐课堂,由于音乐教师自身对情感教育在音乐教学中重要作用认识不足,导致了他们的教学行为往往只停留在对歌曲的反复教唱这一目标上,因而无法真正激活学生对音乐学科的学习兴趣。立足于小学音乐教学过程中情感教育的意义以及发展现状,具体阐述了如何在音乐教学中更为有效地落实情感教育。     

Effects of physical and chemical characteristics of surface sediments in the formation of shallow lake algae-induced black bloom

Surface sediments are closely related to lake black blooms. The dissolved oxygen （DO） distribution and its penetration depth in surface sediments as well as the migration and transformation of redox sensitive elements such as Fe and S at the sediment-water interface are important factors that could influence the formation of the black bloom. In this study, dredged and undredged sediment cores with different surface properties were used to simulate black blooms in the laboratory. The Micro Profiling System was employed to explore features of the DO and ∑H2S distribution at the sediment-water interface. Physical and chemical characteristics in sediments and pore waters were also analyzed. The results showed that sediment dredging effectively suppressed the black blooms. In the undredged treatment, DO penetration depth was only 50 μm. Fe^2＋ concentrations, ∑H2S concentrations, and ∑H2S production rates were remarkably higher in surface sediments and pore waters compared to control and dredged treatments. Furthermore, depletion of DO and accumulation of Fe^2＋ and ∑H2S in surface sediments and pore waters provided favorable redox environments and necessary material sources for the blooms. The study results proved that physical and chemical characteristics in surface sediments are important factors in the formation of the black bloom, and could provide scientific guidance for emergency treatment and long-term pre-control of black blooms.     

Waste oyster shell as a kind of active filler to treat the combined wastewater at an estuary

Estuaries have been described as one of the most difficult environments on Earth. It is difficult to know how to treat the combined wastewater in tidal rivers at the estuary, where the situation is very different from ordinary fresh water rivers. Waste oyster shell was used as the active filler in this study in a bio-contact oxidation tank to treat the combined wastewater at the Fengtang Tidal River. With a middle-experimental scale of 360 ma/day, the average removal efficiency of COD, BOD, NH3-N, TP and TSS was 80.05%, 85.02%, 86.59%, 50.58% and 85.32%, respectively, in this bio-contact oxidation process. The living microbes in the biofilms on the waste oyster shell in this bio-contact oxidation tank, which were mainly composed of zoogloea, protozoa and micro-metazoa species, revealed that waste oyster shell as the filler was suitable material for combined wastewater degradation. This treatment method using waste oyster shell as active filler was then applied in a mangrove demonstration area for water quality improvement near the experiment area, with a treatment volume of 5 × 10^3 m^3/day. Another project was also successfully applied in a constructed wetland, with a wastewater treatment volume of 1 ×10^3 m^3/day. This technology is therefore feasible and can easily be applied on a larger scale,
