微波浪水池开展海洋工程实验的可行性
Feasibility of Micro Wave Tank for Ocean Engineering Experiments
 [PDF]

赵天奉, , 余阳
Adances in Marine Sciences (AMS) , 2015, DOI: 10.12677/AMS.2015.22002
Abstract:
随着海洋油气开发向深水推进,海洋工程水池趋于大型化,试验成本不断上升。考虑到小尺度波浪实验所具有的参考意义,微波浪水池概念得以提出。微波浪水池具有与大水池相同的造波机制和控制参数,仅是造波机构和实验水体大幅度缩小。在水力试验的几个重要方面,微波浪水池的实验意义得到预测和展望,同时也初步探讨了微波浪水池的局限性及其实验验证的方法。在溢油扩散研究、波面物理场景表现、波能转化、实验工况筛选方面,微波浪水池实验被认为是可行的。
As offshore oil and gas explorations gradually go into deepwater, marine engineering pools tend to be larger and test cost continues to rise. Based on the reference significance of small-scale wave experiments, Micro Wave Tank concept was put forward. Micro Wave Tank has the same wave- making mechanism and control parameters as big pools, but the wave paddles and water area sig-nificantly shrink. In several important respects of hydrodynamic test, the experimental significance of Micro Wave Tank has been expected, and also the limitation and experimental verification methods of Micro Wave Tank are discussed. On the research aspects like oil spill diffusion, wave-front scene simulation, wave energy conversion and filtering conditions, Micro Wave Tank expe-riments are considered feasible.

异丁烯氢甲酰化用负载型PPh3-Rh-Co/SiO2配合物高效催化剂
易敏,徐士伟,,
分子催化 , 2005,
Abstract: 制备了SiO2担载的Rh-Co双金属配合物催化剂,用FT-IR、TPR和TPD等手段对催化剂进行了表征,并用异丁烯氢甲酰化反应考察了催化剂的性能.结果表明,Co和Rh之间存在协同效应,这种协同效应可以促进二者在载体表面的分散;可以促进催化活性物种前驱物数量的增加,从而提高催化剂的催化性能;氢甲酰化反应产物中没有副产物特戊醛的生成;经过研究和优化,高效催化剂在2.5 MPa反应压力下5 b内异戊醛的平均产率可达1257.5 mol/mol-Rh?h.

华西口腔医学杂志 , 2010, DOI: 10.3969/j.issn.1000-1182.2010.01.022
Abstract: 目的探讨植入位点不同时颧骨种植义齿种植体-骨界面的应力分布规律。方法计算机模拟建立上颌后牙区重度萎缩三维有限元模型,分别在第一前磨牙区、第二前磨牙区、第一磨牙区和第二磨牙区模拟颧骨种植义齿修复。进行垂直向、颊向30°和舌向30°加载100N,统计分析植入位点不同时颧骨种植义齿种植体-骨界面的应力。结果1)第一前磨牙区颧骨种植体颊侧暴露较多,与临床不符。2)上颌后牙区拉应力峰值比较:选择第二磨牙区植入时最大,第二前磨牙区次之,第一磨牙区最小。上颌后牙区压应力峰值比较:选择第二磨牙区植入时最大,第一磨牙区次之,第二前磨牙区最小。颧骨区拉应力及压应力峰值比较:选择第二前磨牙区植入时最大,第一磨牙区次之,第二磨牙区最小。结论选择第一磨牙区颧骨种植义齿修复较好。

Mine Engineering (ME) , 2015, DOI: 10.12677/ME.2015.33013
Abstract: 采用层次分析法,计算矿区内的企业(包括露天煤矿、井工煤矿、石灰厂、硅石厂、洗煤厂、焦化厂、水泥厂、石料厂和铁矿厂)的加权总产污量,全面评价矿区内企业的污染程度。利用污染程度、风频和距离城镇的远近,将矿区划分为四个区块,并制定了相应的治理和预防机制。为矿区环境污染防治工作提供科学依据和指导。
Using analytic hierarchy process, the weighted total pollutant amount of mining enterprises ( in-cluding opencast coal mine, coal mine, lime plant, silica plant, coal preparation plant, coking plant, cement factory, stone material factory and iron ore plant) is calculated to evaluate the compre-hensive pollution degree of the mining enterprises. Pollution degree, wind frequency and the dis-tance from the town are used to divide the mining area into four parts. The results can provide a scientific basis for environment pollution prevention.
