Stakeholder Management in Power Equipment Marketing Projects: A Case Study of H Company
随着近年我国国民经济的高速发展以及智能电网概念的提出和建设工作的逐渐推进,电网对电力仪器设备的需求量正逐步放大。随着市场需求的增加,电力仪器设备企业营销项目的数量也出现了相应的增长,从而对电力仪器设备销售企业的营销项目管理能力提出了更高的要求。尤其是在公司各方面资源基本不变的情况下,如何有效的组织和利用有限的资源,协调内外部关系,在有限的时间内同时管理好上百个营销项目,确保或提升项目完成率,是迫切需要解决的问题。而一直以来,电力仪器设备企业在营销项目管理方面的观念较为落后,由于欠缺科学的管理手段,企业对项目干系人的管理往往只停留在传统的客户关系层面,而忽略了项目全生命周期各阶段的干系人管理,仅...As the rapid development of China's national economy in recent years, as well as the concept of smart grid proposed and the gradual progress of the construction work, the demand for the power equipments is gradually enlarged. Along with the increasing of market demand, the quantity of the power equipment marketing projects also appeared the corresponding growth. Especially in the situation of the ...学位:工程硕士院系专业:管理学院_工程硕士(项目管理)学号:X201215307

长江中游三个湖泊中华绒螯蟹生长变化研究
选择长江中游的牛山湖、武湖和东汤逊湖三个典型的河蟹养殖湖区作为研究地点,从2009年2月起逐月调查湖泊放流河蟹体重和壳宽的生长变化,并同时记录投喂管理情况和收集试验湖区的水化特征及底栖生物资源状况。调查发现,河蟹在4、5、6月特定生长率最大,此时为河蟹生长的高峰期。在三个湖区间,生长有显著性差异,在收获季节,武湖河蟹的平均壳宽和体重均显著性大于另外两个湖区(P0.05);这种情形可能主要与为湖泊的天然饵料资源的种类和丰度有关

Effect of ZnO on Cu/ZnO/Al_2O_3 catalysts for methanol synthesis
[中文文摘]用高速碰撞共沉淀法制备m(CuO) /m(ZnO) /m(Al2 O3 )比分别为 60 /3 0 /1 0和 3 0 /60 /1 0的 1 #和 2 #催化剂 ,结果表明高ZnO的 2 #催化剂活性较好 ,分散度较大。XPS测试表明 2 #催化剂表面ZnO吸附的中间体 (CHx 或CHxO)较多且表面的Cu+1浓度较高 ,从而促进CO加氢合成甲醇的活性。[英文文摘]Cu/ZnO/Al_2O_3 catalysts with ratios of 60/30/10 and 30/60/10 have been prepared by high speed collision coprecipitation method. The performance of the catalyst with the higher ZnO content shows the higher activity in methanol synthesis. The characterization results indicated that the catalyst with the higher ZnO content has higher dispersion. On the surface of the higher ZnO content catalyst, there was more Cu+1 and more intermediate (CH_x and CH_xO) adsorpted. It is beneficial for the CO hydrogenating to produce methanol

Photosynthetic capacity of three common species of macroalgae and the application in coral aquarium
利用水下饱和脉冲调制叶绿素荧光仪(dIVIng-PAM)测定了珊瑚养殖水处理中3种常见大型海藻石莼(ulVA lACTuCA)、条浒苔(EnTErOMOrPHA ClATHrATA)和羽状蕨藻(CAulErPA MEXICAnA)光能转化效率(fV/fM),快速光曲线(rlC)相关参数和非光化学淬灭(nPQ)。结果表明:石莼和条浒苔的fV/fM分别为0.808±0.004和0.816±0.009,显著高于羽状蕨藻。最大相对电子传递速率rETrMAX(17.52±2.92和19.59±4.43μMOl E·M-2·S-1)、半饱和光强Ik(53.41±8.18和59.71±13.52μMOl PHOTOnS·M-2·S-1)也明显高于羽状蕨藻(rETrMAX和Ik分别为13.72±5.41μMOl E·M-2·S-1和32.67±14.06μMOl PHOTOnS·M-2·S-1),表明石莼和条浒苔有着比羽状蕨藻更高的光合能力和对强光的耐受能力,光保护能力更强;羽状蕨藻较高的rlC初始斜率α表明其在弱光下拥有更强的光捕获能力,弱光下光合效率更高;随光照的增强(0~373μMOl PHOTOnS·M-2·S-1),羽状蕨藻nPQ的增幅有限(0~0.2),最大值仅为条浒苔和石莼的38.1%和62.5%,表明这种藻类更容易受到强光的抑制。因此,在珊瑚养殖的水处理中,可以根据不同的光照选择适宜的藻种或藻种组合并根据光梯度进行布局,反之也可以根据藻种来选择合适的光源,以达到最佳的处理效率。This study investigated the difference of photosynthetic capacity in three macroalgae species( Ulva lactuca,Enteromorpha clathrata,and Caulerpa mexicana) commonly used for nutrient removal in coral aquariums.The photochemical efficiency( Fv/Fm),parameters relevant to rapid light curve( RLC) and non-photochemical quenching( NPQ) in the macroalgae were measured by underwater saturation pulse modulated chlorophyll fluorometer( Diving-PAM).The results showed that Fv/Fmwas 0.808 ± 0.004 for U.lactuca and 0.816 ± 0.009 for E.clathrata,which were higher than that for C.mexicana.Higher maximum relative electron transfer rates( rETRmax)( 17.52 ±2.92 and 19.59 ±4.43 μmol e·m- 2·s- 1) and half-starved value of light intensities( Ik)( 53.41 ±8.18 and 59.71 ±13.52 μmol photons·m- 2·s- 1) were observed in U.lactuca and E.clathrata than that in C.mexicana( 13.72 ± 5.41 μmol e·m- 2·s- 1for rETRmaxand 32.67 ± 14.06 μmol photons·m- 2·s- 1for Ik),indicating that U.lactuca and E.clathrata have stronger photosynthetic capacities,photo-protection capacities and tolerance to higher intense light than C.mexicana.A significantly lower RLC initial slope α in C.mexicana implied that this algal species has a higher photosynthetic capacity under weak light condition.With increasing the light intensity( 0- 373 μmol photons·m- 2·s- 1),however,C.mexicana had a limited increase of NPQ( 0- 0.2),the maximum of which was equivalent to 38.1% of that in U.lactuca and 62.5% of that in E.clathrata.These results indicate that the photosynthesis of E.clathrata may be more easily limited by intense light.Our study suggests that the selection of algal species for nutrient removal in a coral aquarium should be adapted to the light intensity.Single species or the combination of different species of macroalgae can be selected according to the illumination of the coral aquarium in order to maximize the efficiency of nutrient removal.国家海洋局第三海洋研究所基本科研业务项目(海三科2011033); 厦门海洋研究开发院共建项目; 海洋公益性行业科研项目(201105012)资
