胸神经后皮支及其营养血管的解剖学研究

目的：为临床设计背部皮神经营养血管皮瓣提供解剖学基础。方法：在l7例34侧成人躯干标本上，用显微解剖法观测第l—l2胸神经后皮支及其营养血管的来源．走行及分布规律。结果：第l—l2胸神经后皮支的伴行动脉为肋间后动脉的背侧皮支。皮神经及其伴行动脉于脊柱两旁相应肋间穿出深筋膜，呈节段性、重叠性分布于背部皮肤，皮神经营养血管相互间形成丰富的吻合。结论：可设计以第l—12胸神经后皮支及其营养血管为蒂的皮神经营养血管皮瓣。     

异花玉兰的冬态特征观测

对异花玉兰的冬芽种类、拟花蕾、分枝习性及成枝规律等因子进行了观测,并对冬芽和拟花蕾进行解剖,结果表明:1当年生枝上有休眠芽、叶芽和拟花蕾3种;2叶芽与拟花蕾外均包被着3~4层芽鳞状托叶,最外层薄革质,外面密被短柔毛,内层纸质-膜质,外面疏被长柔毛;3分枝习性基本为预生分枝呈单阶无歧生长规律。     

Utilization of Livestock''s Dejection as Biogas Origin in Building New Countryside in Heilongjiang Province--Developing Utilization of Biogas and Promoting Energy-saving and Emission Reduction

With the startup and execution of new socialistic countryside construction in Heilongjiang Province,the transition from castoff to resource is strengthened in the countryside,aiming at neat appearance of the countryside,clean production and saving energy.People produce biogas and provide the countryside with new energy by means of turning livestock's dejection into resources,composting of the plant and animal's leavings in the courtyard and even in the factory.It is helpful for the countryside to conserve t...     

农村基层党组织“枢纽型”人才开发模式研究——以农村党建助理员和乡村振兴协理员为例

深入推进 “街乡吹哨，部门报到 ”工作需要农村基层党组织培养更多 “枢纽型 ”人才。通过对北京怀柔区和门头沟区等地党建助理员和乡村振兴协理员进行专题调研，发现农村基层党组织人才培养存在重形式轻评估、重制度轻机制、重业务轻意识等问题，建议从标准化课程、全域化师资、规范化流程、交互化平台、长效化管理等五个方面开展人才培养系统工程建设，从而更好地为京郊农村社会事业发展服务。     

不同激素对金花茶圈枝繁殖生根的影响

分析NAA、IBA及2种激素等体积混合溶液对金花茶圈枝繁殖生根成活率的影响。结果表明:采用萘乙酸和吲哚丁酸的等体积混合激素溶液1 000~1 500 mg/L能明显提高金花茶圈枝繁殖苗的生根率,达到95%以上。该技术简化了操作程序,可节省人力,在基质方面也节约了生产成本,可直接应用于金花茶苗木大规模生产。     

萝卜各级分枝种子质量比较

对萝卜各级分枝种子质量检验表明，萝卜各级分枝种子质量不一，以主轴顶端和基部新发枝种子质量最差，3级分枝种子质量最好，2分枝和1级分枝稍次。各分枝种子播种后，幼苗质量与种子室内检验质量结果相统一，1级、2级、分枝种子收获量最多，分别为种子收获总量的45％和38％。     

不同花生品种侧枝发育动态与产量性状研究

花生一级侧枝发育具有不均衡性。第一、二对侧枝出现早，伸长快，其他一级侧枝出现晚，伸长慢。86036－26－1第一、二对侧枝发育相对较早，而其他一级侧枝发育较晚；海花1号和豫花1号第一、二对发育相对较晚，而其他一级发育较快；豫花7号和鲁花9号居中。海花1号一级侧枝及第一对侧枝的二级侧枝数最多，86036－26－1的一级侧枝数及第一对侧枝的二级侧枝数量少。在花针期之前第一对侧枝的伸长与主茎基本同步；花针期之后，第一对侧枝伸长速度超过主茎。86036－26－1的一级侧枝长及株高居首位。86036－26－1第一、二对侧枝饱果率，产量居第一，豫花7号居第二。海花1号虽然荚果数较多，但第一、二对侧枝孢果率较低，产量也较低；鲁花9号居中。     

Existing Situation on Disposal of Sludge from Wastewater Treatment Plant in Three-Gorges Reservoir Area

At present 18 wastewater treatment plants operateing in the Small towns of Three Gorge Areas of Chongqing Municipality, producing 132.95 tons surplus sludge everyday. As regards to the disposition of such numerous surplus sludge, the major disposition technique in these wastewater water treatment plants, i. e. , thickening and mechanical dewatering technique followed by feeding into the municipal solid waste landfill, seems to have a rather bad effect on the normal operation of the municipal solid waste landfill, due to the unstabilized sludge resulted from this technique of the sludge disposition and high moisture in the sludge, which is higher than 80%. This paper has paid some attention to this phenomenon. With respect to the small towns having the the municipal solid waste landfill, the techniques of mechanical dewatering, calcareousness stabilized etc. before feeding into the municipal solid waste landfill, seem to be feasible, while the composting and comprehensive utilization of sludge is available in the small towns which have no municipal solid waste landfills.
