Taking an example of developing auxiliary system on 200 km/h Electric Multiple Unit, the au-thor describes the basic concepts and methods for confirming the electric system principle, system structure andcontrol logical, and makes a proposal for the development of auxiliary system.
The article presents the development intention of HTS transformer for electric multiple unit and the characteristics of 300 kVA HTS transformer's prototype,describes the main technical theories of the project research,and puts forward 3 000 kVA HTS transformer's concept design on the base of 300 kVA HTS transformer's prototype development and manufacture.
The compounds have ferromagnetic properties, and their Curie temperature ranges between 280 and 340 K, the saturation magnetization σs(5 K)≈7.5 emu/g.
Measurements on SQUID and vibrating-coil magnetometers suggested that CoBO3 is a magnetically ordered crystal with a saturation magnetization of 50 emu/g in the basal plane at 4.2 K and a Néel temperature of 53 K.
The spontaneous weakly-ferromagnetic moment is 0.56 emu/g at 10 K.
The coercive force and saturation magnetization of amorphous samples were found to be 1 Oe and 130 emu/g, respectively.
The coercive force and the saturation magnetization of the amorphous samples were found to be 1 Oe and 130 emu/g, respectively.
Parentage in emus (Dromaius novaehollandiae) was examined by microsatellite analysis using four independent loci.
These results lead to a reassessment of behavioural observations of emus, the consequences of parentage distribution, and theories about mating systems and sexual selection.
In control emus, 94.8% of water, 99.8% of Na, and 98.7% of Cl were reabsorbed.
Data from emus sitting and standing at-5°C, when metabolism is 1.5x and 2.6x basal metabolic rate, respectively, indicate that at least in the emu an increase in oxygen extraction can be stimulated by low temperature independent of oxygen demand.
A biochemical approach was used to study the evolution of ratite birds, i.e., the ostriches, rheas, cassowaries, emus, and kiwis.
