The CrO2 -Cr, O3 equilibrium curve has been determined up to 35 kbars and 1400° C with a piston-cylinder apparatus. The phases were determined by magnetic, X-ray, and microscopic examination. The phase boundary can be represented by a straight line log P versus 1/T plot, where log P = 5.3 - 1400/ T. These results can be extrapolated to agree reasonably well with the results of previous investigations using gas pressure techniques. 相似文献

Phase equilibrium in the system MgO-H2 O was investigated from 500° to 1450° C at 5 to 40 kbars by a quenching technique using a piston-cylinder apparatus. Brucite decomposed to periclase plus vapor at 810° and 10 kbars, 945° and 20 kbars, 1000° and 32 kbars, and 975°C and 40 kbars. The slope of the decomposition P-T curve became steeper with increasing pressure, infinite at 32- kbars and 1000C, and then negative above 32 kbars. The extrapolation of this curve to lower pressures agrees well with data of other workers who used hydrothermal techniques. 相似文献

Nowadays, trials to use even higher frequencies are pursued to realize high‐speed wireless communications. In order to respond to such a trend, dielectric properties of insulating polymers at high frequencies have to be clarified, although the importance of clarifying low‐frequency properties is still very high, especially for use as high‐voltage insulators. In this regard, complex permittivity spectra from 10 mHz to 4.0 THz were obtained for various insulating polymers. The spectra obtained in the very wide frequency range are important, because they can be a valuable database and they provide various pieces of important information on dielectric characteristics. 相似文献

An adjustable‐speed flywheel generator (FWG) can control both active power and reactive power rapidly. We have studied the effect of FWG installation on a large‐ capacity, long‐distance transmission system, especially when the system includes loops. In this paper, we describe the selection of FWG location, the selection of stabilizing control input signal, and the required quantities of FWG. FWG location is selected by a PQ‐sensitivity method, calculation of which is simple and permits easy understanding of the effect of both FWG's active and reactive power. As a stabilizing control input signal, we use bus voltage frequency instead of power flow because the flow changes stepwise by opening three‐phase single‐circuit. Additionally, we clarify the FWG quantities that must be designed, such as FWG's active power and reactive power. We considered FWG's slip to determine the quantity because the capacity of the exciter depends on slip. © 1999 Scripta Technica, Electr Eng Jpn, 127(2): 32–41, 1999 相似文献

We examined the effect of a solution-stirring method on human triosephosphate isomerase crystallization. The crystals diffracted to more than 1.4 A resolution, whereas those obtained by the normal vapour-diffusion technique diffracted to 2.8 A. These results clearly show that the solution-stirring method is valuable and useful for protein crystallization because of its effectiveness and simplicity. 相似文献
