2012年计算机应用与系统建模国际会议

作者： Ji Li Rong mo Key Laboratory of Contemporary Design and Integrated Manufacturing Technology Ministry of Education Northwestern Polytechnical University

The merge and interaction of manufacturing and services trigger emergence of service-embedded manufacturing paradigm. Due to the development of this advanced manufacturing paradigm, product Service Network modeling is proposed in this paper. Firstly, the concept and characteristics of the network as well as the relationship between products and services were deeply analyzed. Then the BOM to meet the needs of the service-embedded manufacturing was established. The service-embedded manufacturing network model was constructed on this basis. The model includes design, manufacturing and maintenance and was oriented to product life. The network model will Provide valuable information and research material to the service-embedded manufacturing both in theory and practice.

通过对扬子克拉通古大陆边缘不同时期沉积岩的mo同位素进行测定,结合mo微量元素组成,对古大陆边缘mo的自生作用规律进行了研究,并根据mo丰度对原始有机碳堆积速率进行了计算.结果表明,其原始有机碳堆积速率在0.17～0.67mmol/m2/day之间.利用已建立的现代大陆边缘δ98mo与有机碳埋藏速率模型,对该区不同时期沉积岩的有机碳埋藏速率进行恢复.结果表明,扬子克拉通显生宙不同时期沉积岩的有机碳埋藏速率有较大的变化范围(0.43～2.87mmol/m2/day),并与原始有机碳堆积速率具有明显的相关性,因此,δ98mo有可能成为评价有效烃源岩的潜在指标.

【目的】探明不同氮磷钾配比施肥对1年生中国无忧花(Saraca dives Pierre)幼苗生理特性的影响,为培育中国无忧花幼苗提供理论依据。【方法】以中国无忧花幼苗为试验材料,采用尿素(N)、过磷酸钙(P2O5)、氯化钾(KCl)施肥量的L9(34)正交试验设计,以不施肥处理为对照(CK),分析不同氮磷钾配比施肥中国无忧花幼苗的生理特性。【结果】不同氮磷钾配比施肥处理中国无忧花幼苗叶片POD和SOD酶活性均存在显著差异(Pmol/g;N_(2)P_(1)K_(2) 处理最低,为10.33μmol/g。各光合色素含量均高于CK,其中,叶绿素a、叶绿素b和总叶绿素与CK间差异达显著水平。叶绿素a和总叶绿素含量N3P1K3处理最高,分别为2.14 mg/g和3.07 mg/g,叶绿素b和类胡萝卜素含量N3P2K1处理最高,分别为0.94 mg/g和0.46 mg/g。POD和SOD酶活性间及各光合色素含量间呈极显著正相关。【结论】不同氮磷钾配比施肥下,中国无忧花幼苗各生理指标均优于未施肥处理,其中,叶片可溶性蛋白、可溶性糖含量显著高于未施肥处理;随着氮肥量增加,叶绿素、类胡萝卜素含量均显著高于未施肥处理。合理的钾肥量搭配适量的氮、磷肥更能有效促进中国无忧花幼苗可溶性蛋白、可溶性糖的产生与富集,氮素在中国无忧花幼苗光合色素方面起主导作用。以施用尿素2 g/株、过磷酸钙1.6 g/株、氯化钾3 g/株处理(N_(2)P_(2)K_(3))的中国无忧花幼苗生理状况最好。

在新时期教育对外开放的背景下,我国高职教育中外合作办学进入了由规模扩张转向内涵发展、以提质增效为显著特征的新阶段,但是,其在区域、专业、外方合作者和学位文凭的获得上存在着与我国经济和社会发展不符的现象。这些现象的出现,既有利益驱动的误导,也有政策安排缺位及本土化环境缺失的原因。鉴于此,新时期高职教育中外合作办学需要在办学定位、政府引导、质量建设等方面进一步完善,以促进其可持续发展。
