    基于场量测量和频率扫描技术的交变漏磁无损检测系统
    The key of this part is to verify that the structured singular value of a one-unknown matrix function is not equal to one. This work can be accomplished by a frequency sweeping test method.
    后者的核心是判定某个以频率为变元的矩阵的结构奇异值不等于1,这一问题由频率扫描测试法解决。
    All structure of bifurcation and chaos can be shown on the V0-ω parameter plane by the method of frequency sweeping. The normal and inverse bifurcation sequences are fully symmetric.
    在V_0-ω外控参数平面上,频率扫描显示了分岔与混沌的整体结构:正的和逆的倍周期分岔序列的对称性;
    This paper mainly discusses the precise positioning method for the urban seismic mobile moving fault, and the study results shows: the frequency sweeping method and the mutual correlation method of data processing can effectively suppress the disturbances from strong vibrations with the vibroseis in the strong-disturbance background in the city so as to carry out the seismic investigations in the urban area;
    重点讨论了城市地震活动断层精确定位方法. 研究结果表明:面对城市的强干扰背景,利用可控震源,采取频率扫描方法和数据处理的互相关技术,可以有效压制强振动干扰,实现城市市区的地震勘探;
    This paper studied the aging effect of Short Term Oven Aging method and Long Term Oven Aging method on asphalt mixes. Penetration,Brookfield Viscosity and DSR Frequency Sweeping tests were used to evaluate the aging of the different aged asphalt reclaimed from the STOA and LTOA mixes.
    应用沥青针入度、布氏粘度和DSR频率扫描等试验方法,评价了SHRP沥青混合料短期老化(STOA)和长期老化模拟方法(LTOA)的老化程度,并与经过SHRP沥青胶结料的标准短期老化(RTFO)和长期老化(PAV)方法后的沥青胶结料性能进行了对比研究。
    The fast flaw-recognition model based on the magnetic field measurement and the depth-detection model based on the frequency sweeping method were built. Experimental results proved their accuracy.
    在对交变漏磁检测理论进行分析的基础上,提出了基于场量测量和频率扫描技术的快速识别和深度定量检测模型,并通过试验证明了该模型能实现表面缺陷的快速检测和缺陷深度的定量检测。
