When cab signalling equipments receive 25Hz AC count- ing code signals from rails,there is severe interference from the interference signals,in which the most serious is from the 50Hz unbalanced rail pulling current.
In this paper, on-line monitoring and diagnosis system for traction transformer is designed based on DGA (dissolved gas-in-oil analysis) technology to realize the online monitoring the traction transformer oil dissolved gas H2、CO、CH4、C2H6、C2H4、C2H2.
The model of helical motion [4] is used in this paper in considering the influence of the three-dimensional behavior of an adiabatic flow on the flow and traction characteristics of the nozzle.
rectus femoris) transfer forces/powers from one joint to another, thereby compensating for the physiological shortcoming of monoarticular muscles, that is, a decrease in the tractive force with increasing contraction rate.
The tension tests prove that transversal fractures, fractures due to a tearing apart of the tendons, and other rents will not occur due to a merely linear diverging tractive power.
Even by applying tractive forces in the range between 30-40 kg or by enhancing with a manual draw we did not succeed in bringing about an obstruction of the vertebral arteries.
It is shown that the reason for such an effect can be the pulling of cations into the dense layer resulting from the formation of associates of cations and specifically adsorbed anions OH-.
A relation between the transition of investing tissue to the oriented and stressed-deformed state and the direction of the traction vector was established.
The effect of the managanese(II) acetate concentration on the traction selectivity with respect to the oxidation of the methyl group of the substrate is reported.
The traction distribution as a function of oscillation frequency, which is needed in calculations of transducer efficiency, has been determined with the help of the method of finite boundary elements.
