国家林业局昆明勘察设计院职工队伍存在着:知识结构单一,缺乏复合型高级人才;离退休人员过多,职工负担过重;市场观念淡薄,竞争意识不强;功能单一,机制不活,职工队伍缺乏生机和活力等诸多问题。自1984年实行差额拨款后,已经采取了以下措施:建立“能上能下”的干部选拔任用机制;建立“能进能出”的人才管理机制;建立“能多能少”的弹性分配机制。并对今后工作提出了若干建议。 相似文献

本文就如何保证农产品农药残留能力验证实验结果满意需要注意几个关键点进行探讨分析。要想通过板栗中毒死蜱农残的能力验证,样品前处理采用NY/T 761的方法,必须注意:提取液的过滤要用定性滤纸或脱脂棉,提取液过滤后静置时间控制在30 min~40 min之间,吸取10 mL乙腈液体要准确,净化步骤的水浴温度要严格按照方法要求,氮吹切记不要吹的太干,吹到潮乎乎为宜,SPE小柱的活化平衡要充分,上样时液面不能流干,上样后尽可能流干再洗脱,最后定容5.00 mL要准确。检测结束后,对结果进行验证很重要,可采用盲样的空白基质基质配标和空白基质基质加标画标准曲线两种办法。 相似文献

In the process of evaluating the physical quality of soil for crop production, measurable sources of stress that the soil imposes on growing crops must be identified. Approaches for monitoring or evaluating soil physical quality should then be based on properties or processes that relate to these stresses and must be measured against definable standards. We hypothesized that process capability analysis applied to measurements of soil water content and the least limiting water range (LLWR) would meet these requirements and could be used to evaluate the physical quality of soils for crop growth. Previously published data obtained over 3 years in a field with a variable landscape planted to corn under no-till were used to test the hypothesis. The temporal variability of soil water content was regarded as a process which aims to generate individual values for soil water content inside the limits specified by the LLWR. Process capability analysis successfully linked the temporal variability of soil water content in relation to the LLWR. The main process capability parameter, i.e. distance to nearest specification (DNS) varied by a factor of three across the landscape and was related to clay and organic carbon contents. Values of DNS were strongly correlated with shoot growth (R2 = 0.97) suggesting that DNS effectively characterized the spatial variability in stresses imposed on plant growth by soil and described changes in the soil physical quality for crop growth across the site. The results supported our hypothesis. 相似文献

高效聚磷菌的筛选及除磷特性分析 总被引:3,自引:0,他引:3
从运行稳定的SBR反应池好氧末端的活性污泥中分离筛选出1株高效聚磷菌LB4,结合生理生化特征分析和16S rDNA分子生物学技术,鉴定该聚磷菌为鲍曼不动杆菌(Acinetobacter baumannii);以EBPR工艺过程为载体,模拟将来可能采用的含可利用碳源的工业废水作为进水,探讨了不同营养条件下菌株LB4的除磷行为,初步分析了其代谢机理,研究表明:菌株LB4除磷的最佳温度为30℃、最适pH值为7.0,微量元素的有无对该菌株的除磷效能影响不大,提高生物除磷系统除磷效率的关键是提高厌氧释磷量. 相似文献
