鲁北地区商周时期的海盐业

采用XRD和XRF分析测试方法，研究了山东省渤海湾地区滨州市阳信县李屋遗址和寿光市大荒北央遗址出土的商代晚期的陶器——盔形器及附着土壤．样品的Na元素和Cl元素XRF分析结果表明：李屋遗址和大荒北央遗址出土的盔形器的含盐量明显高于其他样品，显示这二地的盔形器与早期海盐生产有关．李屋遗址出土的盔形器表面附着土样用去离子水过滤后，滤液结晶体的XRD分析结果，进一步表明该盔形器是商周时期渤海湾地区海盐生产的器物．大荒北央遗址出土的盔形器的内壁沉淀物与长江三峡中坝遗址出土的花边陶釜的内壁沉淀物具有基本相同的物相，这进一步表明其与海盐生产有关．

Fecundity of the blood-feeding insectRhodnius prolixus increases in successive periods of egg production

The fecundity of the blood-feeding insect,Rhodnius prolixus, was observed to increase in successive periods of egg production, each period being triggered by a single large blood meal. As previously published, the fecundity of mated animals was significantly higher than that of unmated animals for the first period of egg production. For a second period of egg production, fecundity increased significantly in both mated and unmated animals. By the fourth period, fecundity had returned to first-feed values for mated animals, but remained high for unmated animals, and the fecundity of mated and unmated animals was not significantly different. Thus, during successive periods of egg production, the processes which maintain fecundity of unmated animals below that of mated animals are overcome.     

Lack of effect of dihydroergotamine on endothelial and smooth muscle cell proliferation and endothelial cell prostanoid production

Summary The most important effect of dihydroergotamine is venoconstriction, but certain metabolic effects and changes in vessel prostanoid activity have also been suggested. In this study endothelial cell production of 6-keto PGF₁ and TxB₂ was quantitated in vitro. No evidence of altered prostanoid production was noted after incubation with dihydroergotamine (exposure ranging from 5×10^–3 to 5×10^–7 g/l). Similarly, no effect of dihydroergotamine on the growth rates of endothelial cells or smooth muscle cells in vitro was documented.     

FMS生产计划的柔性研究

通过对影响FMS利用率的因素进行分析,本文提出了FMS生产计划的柔性的概念,建立了柔性的指标体系,并对柔性的归一化和综合评判等问题进行了研究.需要特别指出的是,本文首次将系统可靠性理论引入FMS生产计划,并根据其不同运行阶段系统可靠性的变化情况,对制定生产计划提出了建议.
