In order to communicate colour, a requisite is the ability to specify colour appearance. Before this can be achieved, a systematic method of describing colour appearance is necessary. Several colour order systems exist, but their approaches are often quite different and their colour ranges limited. Rather than choose a single system for internationalstandardisation, Neville Smith and Fred Billmeyer argue that it would be better todevelop a wealth of user-specific systems that could be interconverted by a common intermediary notation. 相似文献

The performance of a modified virtual impactor with a clean air core in the center of an aerosol flow is described. With this feature, the modified virtual impactor has overcome the inherent disadvantage of conventional designs which have fine particle contamination in the coarse particle fraction. Furthermore, the separation efficiency of this impactor can be predicted from the efficiency curve of the conventional type virtual impactor and the ratio of clean air flow to the total flow rate. With a higher clean air flow, the 50% cutoff Stokes number slightly increases and the efficiency curve has better separation characteristics. Internal wall losses in the impactor are a function of particle size and reach a local maximum near the 50% cutoff size. 相似文献

A multistage virtual impactor has been designed and fabricated consisting of two separation stages yielding three particle size classes. Efficiency and loss curves have been experimentally determined at ambient conditions for each stage. The small physical size and ability to operate at low flow rates make the impactor very versatile. The uses for a multistage virtual impactor range from high pressure, high temperature applications to ambient personnel monitoring. 相似文献
