The procedure and characteristic of the arc discharge,feature of ignitron,firing way,structure features and its application are described in the paper.
Retroengine's firing time must the accuracy control, the firing time differ 1 second, will cause the airship point of descent position difference kilometer.
This paper introduced substitutes for lead,leadless frits and leadless glaze formulation design and making techniques,and then expatiated on firing of leadless glazes,plumbeous recontamination,etc.
The paper also presents the relationship between structures of different kindsof glost-colours formed in the course of firing and the amount of dissolved lead.
Results It showed the changes of field potentials and neural firing rates in hippocampal CA1 region tinder anesthetization of Pentobarbital sodium and Urethane respectively.
Abstract: Objective To investigate the changes in the firing activity of noradrenergic neurons in the locus coeruleus (LC) in a rat model of Parkinson disease (PD).
