The experimental results showed that the frictional factor periodically fluctuated with the time variable, and its amplitude was obviously affected by the change of Reynolds number and pipe diameters. The amplitude and average value of frictional factor both decreased with the increase of Re number, but the bigger the tube diameter was, the larger the amplitude of frictional factor was.

modulation is the transmission of information to be loaded onto a high-frequency signal in the process.amplitude modulation using signal to control the rate of carrier,with its linear modulation signal changes,and maintain the same carrier frequency.in the amplitude modulation,in accordance with the strength of signals in the spectrum of different components,it is divided into ordinary am (amplitude modulation standard am),with inhibition of bilateral carrier am,the carrier single sideband suppression am.the main difference is the different methods and structure of the spectrum.
摘 要:调制是将要传送的信息装载到某一高频信号上去的过程。振幅调制是用调制信号去控制载波的幅度,使其随调制信号线性变化,而保持载波的频率不变。在幅度调制中,根据已调信号的频谱分量不同,分为普通调幅、抑制载波的双边带调幅、抑制载波的单边带调幅。它们的主要区别是产生的方法和频谱结构不同。

Home position shear tests of slope rock, point loading tests and indoor AMD simulation action tests in XingQiao concave slope had show shearing strength and coherence between body layers of quartz sandstone decrease by 13.2%~21.3% after attacked by AMD, the angle of internal friction between layers is decreased by 5.0%~7.5%, in general, AMD affects the rocks mechanical property at range of 60~100m interior the perpendicular slop. Data analysis shows: 1 The actions to slope are major focused on zone of weakness, shearing strength of slope foot and AMD centre are reduced by 52% and 64.7% separately. 2 The explosion stress wave of long distance field has obviously increasing influence to disturbance amplitude value of slope with increasing of the slope height and distance, the response of the top of slope and fault region are obvious as well as damage effect; the foot of slope is with smallest disturbance amplitude value, the disturbance amplitude value of the step close to free face is obviously bigger than the interior of slope. 3 With the coupling effect of the AMD and explosion loading, the stress distribution inside of slope mainly presents characters of explosion stress field; the area affected by AMD becomes a weak area of shearing stress.

The quantum amplitude amplification is the generalization of quantum Grover search algorithm. In this strategy, the Grover iteration has been replaced by two different quantum amplitude amplification operations. This makes it possible to collapse the system with probability 1, in other words, with certainty. The measurement operation in this scheme is only used to cancel the phase factor. Finally, one can use the admissible control to drive the system from the eigenstate to the target state and the control task is accomplished.
