On the other hand, under high-frequency wave conditions, the two bodies move in an inverted phase, enlarging the relative motions. Further, when the larger floating body is located upstream, there is a significant shielding effect on the downstream small body. Keywords: hybrid two-way ...
12."Gasoline engines vary significantly in size, weight per unit of power generated, and arrangement of components."汽油引擎的尺寸、重量功率比和部件安排的变化范围很大。 13.The relationships between oscillation frequency, pressure wave amplitude (ratio) and the size (length and diameter) of the acou...
Therefore this chapter will focus on the discharge characteristics of the switching impulse of the air gap, and mainly introduce the effect of wavefront time, size, and structure of the air gap on the discharge characteristics of the air gap under switching impulse voltage. For the design of ...
The stop-band characteristics of waves in cholesteric-liquid-crystal half-space are investigated using the exact wave solution, the Floquet theorem, and th... C Elachi,C Yeh - 《Journal of the Optical Society of America》 被引量: 17发表: 1973年 ...
Plot of frequency content as AC voltage is increased. Closing Remarks In this blog post, we have looked at a particularly attractive approach if you are solving for the time-periodic steady state of a system that can be described by a set of algebraic equations. Note that this approach admit...
