The three-layer delay-line anode(Hexanode) has an increased ability of detecting multi-hit events,compared with a standard two-layer delay-line anode.

The article analyses the relations among active dissipation, power factor and input voltave of asychronous electric motor in operation, explains the electricity-saving Principle of the opcrstive asychronous electric motor when its voltave is reduced, and works out its applied condition under SCR-controlled triggered dy specific delay angle.

The azimuth jam-delay is calculated while the false target and early warning aircraft all move,through reasonable hypothesis,the aerial radiation pattern is drawn,then the model of the amplitude modulated is established and its principle of operation is introduced.

Design and Accomplishment of high-speed Programmable digital delay line system based on CPLD;

158MHz Surface Acoustic Wave Fixed\| Delay Line on GaAs\+*;

Methods A detection delay line and a reference delay line were constructed and the phase of the two delay line changes was evaluated in different ion concentration,pH value,and glycerol PBS at different viscosities.
