提高曲面近似展开精度的方法与实现

通过对不可展曲面近似展开精度的研究，提出了根据曲面曲率的大小对曲面自动进行网格划分，通过对综合展开误差数据场进行数据拟合来选取最优展开基点，基于空间曲面与其展开图间近似的等距变换关系进行展开样形的误差矫正等3种方法，这几种方法的实现在不同程度上有效地减小了曲面的近似展开误差，提高了曲面的近似展开精度。     

A multicriteria approach to identify investment opportunities for the exploitation of the clean development mechanism

The aim of the present paper is to investigate the prospects for the exploitation of the Kyoto Protocol's Clean Development Mechanism (CDM) in Greece. The paper is addressing 3 questions: in which country, what kind of investment, with which economic and environmental return? The proposed approach is based on a multicriteria analysis for identifying priority countries and interesting investment opportunities in each priority country. These opportunities are then evaluated through a conventional financial analysis in order to assess their economic and environmental attractiveness. To this purpose, the IRR of a typical project in each investment category is calculated by taking into account country-specific parameters, such as baseline emission factors, load factors, costs, energy prices etc. The results reveal substantial differences in the economic and environmental return of different types of projects in different host-countries and show that for the full exploitation of the CDM a multifaceted approach to decision-making is necessary.     

New Engineered Particles from Spray Dryers: Research Needs in Spray Drying

This article reviews developments in the simulations of spray dryer behavior, including the challenges in modeling the complex flow patterns inside the equipment, which are often highly transient and three-dimensional in nature. There appears to be considerable scope for using CFD simulations for investigating methods to reduce the rates of wall deposition and of thermal degradation for particles by modifying the air flow patterns in the chamber through small changes in the air inlet geometry. Challenges include building particle drying kinetics and reaction processes, as well as agglomeration behavior, into these simulations. The numerical simulations should be valuable supplements to pilot-scale testing, enabling more extensive and accurate optimization to be carried out than hitherto possible. New understanding of reaction processes and materials science, in combination with recent knowledge of the application of CFD to these problems, may enable new engineered powder products to be developed from the one-step spray-drying process.

我国钢铁行业清洁生产标准HJ/T189存在的问题与修订建议

2006年10月1日起实施的《清洁生产标准钢铁行业》(HJ/T189-2006)存在着一些不足之处,如不及时修订,将无法适应“十一五”期间钢铁工业的发展形势和清洁生产形势,在某种程度上还很容易对国内钢铁企业造成误导,而且会产生一些负面不良影响。根据目前我国钢铁工业的发展形势和国内外钢铁企业已经达到的实际清洁生产水平,就其存在的问题和今后的修订谈了一些看法。

高温型Mo-Al2O3金属陶瓷的研制

将Mo与Al2O3粉体按摩尔比为0．3、0．4、0．5配料，混合均匀后通过粉末冶金法制成3种Mo-Al2O3金属陶瓷试样。在1800℃，2h氢气气氛中烧结后，试样的气孔率随Mo含量的增加呈降低趋势，而强度呈增加趋势。同时，随Mo含量增加，金属陶瓷中Al2O3的晶粒尺寸减小，Mo的形态从以弥散状为主转变为以连续状为主。研制的高温型Mo-Al2O3金属陶瓷测温套管（金属与陶瓷摩尔比为0．4）在真空或N2保护条件下测量高温合金熔液温度时，平均使用寿命达到100次。
