We introduce in detail the circuit current and voltage when the relay is switch - on and switch - off , and make the software in dos and windows . the equipment can dynamic shows the wave of the current and voltage when the relay is switch - on and switch - off
24.
According to the environment of using the car relay , we conclude the condition of switch - on and switch - off of the relay , and make the computer test and control equipment . the theme introduces the simulative load and the design of the equipment hardware
25.
The two analytic examples show that : if the heating and moistening due to convection at the switch - on point is much smaller than all the other terms in the tendency equation , then keeping the " on - off " switches the same as the basic state will produce the right tangent linear model and adjoint model

Urban group , the largest property asset and facility management group in hong kong lights up the central shopping hub of tsimshatsui on 18th november through its 2004 christmas lighting switch - on ceremony cum park lane shopping carnival launching ceremony at the park lane shopper s boulevard
27.
Under operation system of dos and windows , control software is developed respectively . the wave of voltage and current as the ac contactors switch - on and switch - off is displayed dynamically , which make the equipment not only used as general electric life test instrument , but can apply test date for contactor study
