An antenna device shared by three different waves has a single two- stage collinear antenna constituted by half-wave dipole antennas which are adapted for a vehicle telephone signal and are stacked one upon the other. The device allows an AM-FM radio receiver to receive AM and FM broadcast ...
摘要: Unstable regions are determined mainly by means of a graphical analysis for three kinds of waves: electron beam‐electron coupling; ion beam‐electron (electron beam‐ion) coupling; and ion beam‐ion coupling.关键词: physics plasma physics and thermonuclear processes ...
Three kinds of extreme waves are evidenced geologically on Anegada, a low-lying island 120 km south of the Puerto Rico Trench: (1) Modern and historical storms: A coral-rubble ridge lining the island's north shore was refreshed by modern storms and was probably emplaced by historical hurricane...
There are four kinds of brain waves(脑电波)(a, b, o, and e) in our brain.Listening to different kinds of music can make a difference to different brain waves. People think that soft(轻柔的) music is good for a waves. And they can make us remember things better....
Using observed daily temperatures in China, three independent types of heat waves (HWs), including daytime HWs, nighttime HWs, and compound HWs (with both extreme daily maxima and minima), were defined. Different types of HWs showed distinctive preferenc

three kinds of architectural glass,respectively.Moreover, the numerical simulations were carried out to analyze the action processes of the explosion shock waves on the toughened PVB-laminated glass,the common PVB-laminated glass and the float glass, respectively.And the anti-explosion experiments were...
With the wind and waves, we were going in the direction of the whirlpool. We were hopeless. Nothing could save us. It may appear strange, but at that moment, when we were in the edge of the whirlpool, I felt calmer than when we were moving towards it. I saw clearly that there we...
The three primary colors of light to synthesize a virtual experiment is to see. Red, second, three kinds of waves of light can be turned on or off by dragging each other can be viewed together. Select another shadow in front of the light considers apology shadow color, you can create a...
