Historical Perspectives: Practices,st because such a system affords a comparatively easy means for analytically predicting composition In the second phase. The various methods used for the analytical calculations and the assumptions made therein can then be evaluated by direct comparison with experimental data on the system.

International Political Economy Seriesping performance. The low-temperature (about 20°K) surfaces needed to condense nitrogen and oxygen must be shielded from thermal radiation to minimize the load on their refrigeration system, but the shielding surfaces also cause a significant reduction in pumping capability, as measured by the pumping speed of the system for “permanent” gases.

Lu Fo: Fusing Western and Daoist Poetics,search and industry for an evacuating system of low cost capable of handling high mass flows, a pump working on a principle other than volumetric is required. The cryogenic pump, the pumping rate of which can be independent of pressure, is suitable for this role.
